Big shape, no shape, elephant, no shape
In traditional culture, as mentioned in the Tao Te Ching, Chapter 41," Great sounds are rare, but elephants are invisible." It meant that the most beautiful music sounded lonely and silent, and the tall image could not be seen. This concept reflected the Taoist understanding of the nature of things. Truly great and grand images or things often exceeded the definition of shape and form in people's conventional cognition. They were a kind of metaphysical and abstract existence. In addition, there were other levels of interpretation of the " invisible elephant ". From the point of view of an elephant, an elephant was huge and powerful, but its existence was not only reflected by its size and strength. Its existence could be felt through symbolic meaning. In Asian culture, elephants were regarded as mascots, symbolizing strength and wisdom, not only because of their size and strength, but also because of their wisdom and gentleness. From a historical and cultural point of view, in ancient India and Southeast Asia, elephants were used as tools of war and work, as well as for religious ceremonies and celebrations. These historical and cultural meanings deepened the significance of elephants 'existence. In terms of ecological value, elephants were key species in the forest ecosystem. They helped maintain the balance of the forest, promote the growth and reproduction of plants, and protect the habitat of other wild animals, which made the existence of elephants more important and indispensable. Other than that, there was also a mystery novel and manga titled " The Invisible Elephant."
The difference between the Birch and the White Birch
Birch was a general term for about 100 species of trees and shrubs in the Birch family, and the white birch was a decidual tree in the Birch family. White Birch was also known as Iron Birch, commonly known as Pink Birch and Birch Bark Tree, and its scientific name was Beta platyphylla Suk. Birch was found in the cold regions of the Northern Hemisphere. White Birch was widely distributed in the northern hemisphere's Temperate and Cold Temperate, such as China's Qinghai, Inner Mongolia, Yunnan, Xizang, Ningxia and other provinces (regions). In appearance, the bark of the birch tree was smooth, containing resin, white or mottled, with horizontal skin holes, usually peeling off into thin slices. The bark of the old trunk was thick and deep, splitting into irregular fragments. The bark of the white birch tree was gray-white, the branches were dark gray or dark brown, without hair, and the leaves were thick and papery. They were triangular or triangular-oval, with double serrated edges. "Life Like a White Birch" is equally exciting. Everyone is welcome to click and read it!
Birch
In the section of " Journey to the West in the Tang Dynasty ", it was mentioned that Birch was a mythical beast. It was a dream eater that appeared in the dark and shuttled between graves. People still had dreams before they rotted after death. When their dreams were all eaten by Birch, their bodies began to rot. Birch was also an ancient monster. When people held funerals, they would usually use a mask to ward off ghosts and collect the souls of the deceased to guard against monsters like Birch.
birch juice
Birch sap, also known as birch sap, was a liquid that flowed from the trunk of a birchwood tree. In China, white birch trees are mostly distributed in Northeast China, North China, Shaanxi, Ningxia, Gansu, Qinghai, Henan, Sichuan, Yunnan, Xizang and other places. They often grow in mountain forests with an altitude of 400 - 4100 meters. They are common species in broad-leaved forests and mixed conifer and broad-leaved forests, often growing in communities. Birch sap was usually collected in winter and spring. For example, the 15 days from mid-late April to early May in the Xiaoxing 'an Mountains were the prime time for sap collection. Most of the collection methods used were the closed liquid collection method (single plant hanging barrel scattered liquid collection method), which involved liquid collection tubes, infusion tubes, liquid receiving barrels or liquid receiving bags and other liquid collection devices. Fresh birch juice was a colorless, transparent liquid with a slight sweetness. After two or three days, it would ferment and turn sour. In terms of nutrition and efficacy: - In terms of nutritional content, it contained a variety of ammo acid, vitamins (such as vitamins C, B1, B2), fatty acid, minerals (such as potassium, calcium, Mn, iron, etc.), as well as bio-active ingredients such as betulol, betulinic acid, niotic acid, etc. However, there were also opinions that the content of protein, fat, and biochemistry was extremely low, or even zero. The main component was water, the sugar content was between 0.5% and 2%, and the content of protein in every 100ml drink was 0.0003g-0.006g. - In terms of medicinal effects, traditional medicine believed that it had the effects of dispelling phlegm, relieving cough, clearing heat and detoxification, and could be used to treat cough, asthma, red urine, etc. It was also recorded in the "Common Chinese Herbs in Hei Longjiang" that it could also be used to clear heat and detoxify, treat scurvy, gout, and kidney disease. Modern research showed that it had anti-fatigue, anti-oxygen effects, increased the weight of immune organs, and promoted growth and development. - Other uses included the preparation of skincare products, such as birch juice hydrating liquid mask, etc. It could also be used to make wine, make natural refreshing drinks, make syrup, and so on. In terms of commercial products, due to production constraints and other factors, the price of birch juice drinks was relatively high. On an e-commerce platform, the price of 500ml of beverages with 100% pure birch juice ranged from 10 yuan to 20 yuan. The raw juice was difficult to preserve at room temperature. When the temperature was higher than 10 degrees, it should be collected and frozen within 24 hours. Now, there was also a preservation technology that could preserve it for two years.

Birch planting
The following points should be paid attention to when planting White Birch: 1. ** Planting plan **: Not suitable for direct sunlight, not suitable for roadside trees; can be used as landscape and courtyard trees, but must be planted in a relatively shady area. 2. ** Spring and Autumn Planting Method ** - ** Selection of seedlings **: Choose a small tree with a size of about 3cm as the planting target. - ** Transplanting area **: The best place to transplant is in the plains of the northern border. The survival rate is very low in areas with slightly higher altitudes. - ** Soil ball **: When transplanting, the soil ball must be 10 times the diameter of the tree. It is suitable for slightly acidic soil. When planting, it cannot be buried too deep. It must be the same as the original planting depth. - <strong>**</strong></strong> - ** Watering **: To ensure the timely supply of water. 3. ** Soil quality ** - ** Soil improvement **: If the soil quality does not match, the soil should be improved. In order to save costs and achieve results, planting holes are generally used for soil improvement. The PH value of the planting soil should reach 5.0 - 7.0, and it should be mixed with organic fertilizer and slag to increase the nutrients and breathability of the soil. - ** Water drainage **: White Birch trees should not be soaked in water and need to be drained. A layer of stone chips and river sand of about 15 - 20cm can be laid at the bottom of the planting hole to play the role of water infiltration and drainage. The net bag made of fine yarn net can be filled with wood chips, furnace slag, and fungus residue. When watering, water can be poured to the bottom, so that the roots can fully absorb water and improve the survival rate. 4. ** Pillar support **: After planting the tree into the hole, support the tree straight and lift it up slightly to make the root stretch, which is conducive to better and faster rooting and soil reinforcement; fill the soil and step on the soil. Triangular support: Each triangular support should form a 120-degree angle. One end of the support should be buried in the soil about 20cm (buried depth should be determined according to the actual situation). It should be buried firmly. The other end should be fixed at the first branch. The three ends should be tied firmly without hurting the bark. A layer of strip cloth can be wrapped at the binding place to protect the bark from being damaged. "Life Like a White Birch" is equally exciting. Everyone is welcome to click and read it!
Nanjing Birch
There were villages related to the birch tree in Nanjing, such as Huashu Village. Huashu Village was located in Xigang Street, Qixia, Nanjing City. It had a history of more than 1500 years and was named after the planting of birch trees. There was a 150-year-old birch tree at the entrance of the village, and there was also a birch forest in the village. There was a rich natural landscape here, such as white walls and tiles, distant mountain reservoir, large grasslands, kiwifruit gardens, brilliant sunflower flowers, etc. It was surrounded by Qixia Mountain, Tang Mountain, and Baohua Mountain, and the mountains and rivers depended on each other. Huashu Village was also the ancestral home of Qin Ju, the hero of the Southern Song Dynasty who resisted the Jin Dynasty. The village retained the remnants of Qin's general platform, training ground, Zhuangyuan Well, etc. In the village, there were the stone Buddha Nunnery Grottoes carved in the Ming Dynasty. It has successively won the honorary titles of "National Forest Village","National ecological and cultural village","List of China's beautiful leisure villages","Jiangsu characteristic rural village" and so on. It has become a good place for Nanjing citizens to experience the rural scenery. There are many farmhouses and homestays in the village, and you can also buy seasonal agricultural products.

Birch planting
Birch planting required attention to the following aspects: ** 1. Selection of Afforested Land ** 1. ** Light and Terrain ** - Birch trees like light, but they can't stand shade. The planting site can be chosen to be a semi-sunny slope or a sunny slope. However, when planting landscape or courtyard trees, it should not be planted on the side where the sun shines directly. It should not be used as a roadside tree. If it is used as a landscape or courtyard tree, it must be in a relatively shady area. 2. ** Soil conditions ** - Strong adaptability to the soil, like acidic soil, like moist fertile sand or loam. If the soil quality is not suitable, soil improvement can be carried out. Generally, planting holes are used to change the soil to improve the soil, so that the PH value of the planting soil reaches 5.0 - 7.0. It is mixed with organic fertilizer and slag to increase the nutrient content and breathability of the soil. At the same time, the white birch tree should not be soaked and needed to be drained. It was better to plant trees with deep soil. ** 2. Planting plan and specifications ** 1. ** Planning ** - There were different plans for different application scenarios, such as solitary planting, cluster planting in the garden, lawn in the park, poolside, lakeside or beside the road. It was more beautiful to plant in the mountains or hills to form a beautiful scenic forest. 2. ** Specs ** - When planting in spring and autumn, it was better to choose a small tree with a size of about 3 cm as the planting target. The best transplanting area was in the plain area of the northern border. The survival rate was very low in the area with a slightly higher altitude. When transplanting, the soil ball should be 10 times the diameter of the tree. ** 3. Planting Method ** 1. ** Basal fertilizer application ** - When transplanting, put a small amount of organic fertilizer at the bottom of the pit (such as sheep manure, which must be fermented mature fertilizer. Because sheep manure is acidic, acidic fertilizer can improve the soil quality). 2. ** Placing seedlings and covering them with soil ** - The seedling planting time was after the seedlings had fallen leaves and before they germinated (usually before and after the "rain" in early spring). When planting the seedlings, the seedlings were placed in the center of the hole, so that the seedlings were upright and comfortable. They were covered with soil layer by layer, and the fine soil was used to block the roots and compact them. The surface was covered with soil to form a turtle-back shape. ** 4. Post-production Management ** 1. ** Mixed Tree Species Selection ** - Mixed species can choose Chinese Fir, Cryptomeria, oak, etc. 2. ** Nurturing and fertilising ** - Within 2 - 3 years after planting, hoe and fertilizer should be carried out once a year, and crops such as beans, potatoes, Scrophularia, and Dangshen could also be interplanted.

Birch seedling
Birch seedlings were used for planting trees. In terms of seedling cultivation, the seedlings should be sowed in a nursery with flat terrain, deep and fertile soil, sufficient sunlight, and convenient irrigation and drainage. After the suitable plot was selected, it should be cultivated. The depth was about 30cm. After the cultivation, the soil should be broken, and the pesticide (such as FeSO4 or CuSO4 to kill the eggs of soil parasites) and the base fertilizer (usually 1500 - 2000kg/667m squared of decomposed organic fertilizer) should be applied. Then, the ridge should be about 20cm high and 1.2 m wide. About two weeks before sowing, soak the seeds in clear water for 24 hours (stirring once or twice in the middle), take them out and soak them in 0.1% potassium Permanganate solution for 1 - 2 hours, rinse them with clear water and dry them in a cool place. It can be mixed with sand with two times the saturated water content of 60%, maintained at a sowing temperature of 15 - 20 degrees, and often turned over. When the seeds have 30% cracks, they can be sowed. Or because the seeds are small, the seed coat is thin and the penetration is good, they can also be sowed directly (watering before sowing, stirring evenly, and sowing after slightly drying and loosening). Sowing in the northeast region from early April to early May. The sowing was based on drilling, with a sowing width of 5 - 8cm, a row spacing of 20 - 25cm, and a sowing rate of about 3kg/667m <2>. One or two days before planting, water thoroughly. When the bed surface is slightly dry, make it into a dented surface and sow it. Because the seeds are small, there is no need to cover the soil. Use a rake to gently tidy the bed surface, press the wooden board lightly, wet the bed surface with a watering can, and use a bamboo curtain to shade it. Under the bamboo curtain, use a bamboo pole to raise 1 - 2cm along the bed. In terms of water and fertilizer management, the growth of birch seedlings required a high water content. A small amount of watering was needed to keep the soil moist. Water could be sprayed. There was no need for special fertilizers in the early stage of seedling emergence. After the seedlings grew to three or four true leaves, they could apply nitrogen fertilizer once (the amount of fertilizer applied was 4 - 5 kg/667 square meters). After growing to five to six true leaves, the lateral roots began to grow and the speed increased. Topdressing was applied once every two weeks (15kg/667 square meters). In July and August, phosphorus fertilizer could be applied once to promote the lignification of the seedlings. In terms of weeding, due to sufficient base fertilizer, weeds were easy to reproduce after rainfall. It was best to manually weed instead of using weeding agents, and farming could loosen the soil to promote the growth of seedling roots. In addition, the birch seedlings were fragile and extremely sensitive to sunburn and autumn frost. After the seedlings emerged, they should pay attention to rolling up the bamboo curtain to promote growth. "Life Like a White Birch" is equally exciting. Everyone is welcome to click and read it!
