The planting of white birch trees needed to pay attention to the following aspects: ##I. Selection of seedling base and soil treatment 1. ** Nurturing Base Selection ** - They had to choose a plot of land with high moisture and good drainage capacity, ensure that the plot was flat without excess soil, and a place with soft soil and good ventilation as the nursery base. At the same time, there must be sufficient water sources to meet the irrigation and drainage needs, convenient transportation, and a superior geographical location to facilitate maintenance and management. 2. ** Soil Treatment ** - Before raising seedlings, the soil should be disinfected and disinfected to remove harmful organisms such as cutworms and mole cricket. The fertilizer should be applied in advance, mainly with farmyard manure and adding an appropriate amount of compound fertilizer. ##2. Seed Selection and Treatment 1. ** Seed Selection ** - Seeds with full grains and smooth surfaces should be selected to avoid problems such as spots or dents. If conditions permitted, they could go to the seedling base to inspect the sprouting and seedling growth, and conduct a sample survey before the official planting. 2. ** Seed treatment ** - Seven days before the official sowing, the seeds were soaked in a solution containing 0.48% of potassium permanganate for two hours, then taken out and placed into a sealed bag to seal for 30 minutes, and then washed repeatedly with water for 4 - 6 times. The seeds were then soaked in clear water for a whole day, and then germinated indoors at a room temperature of about 19 degrees Celsius. They were rinsed three times a day with clear water at 18 - 20 degrees Celsius. When about 30% of the seeds had cracks on the surface, they could be sown. When dealing with seeds, it is necessary to remove seeds that do not meet the planting standards in time. ##3. Sowing 1. ** Sowing Time ** - The sowing time in different areas should be based on the actual local temperature. For example, in Gansu Province, the average annual temperature is 0 - 15 degrees Celsius, and the rainfall is concentrated in June to August. The altitude is 1500 - 3000 meters, and the average annual rainfall is 300 millimeters. Sowing is usually chosen around May (when the surface temperature is stable at 13 - 15 degrees Celsius). 2. ** Sowing Method ** - In our country, the main method is broadcast sowing. Sow the seeds evenly in the seedling bed, first cover with a layer of 0.5 cm thick fine soil, then cover with a thin layer of river sand and compress it appropriately, and finally cover with a shade gauze. The fine soil, river sand, and gauze must be sterilized. Before the seeds fully germinated, the humidity and temperature of the seedling bed should be controlled within a reasonable range. ##4. Planting 1. ** Planting Planning ** - It should not be planted on the side where the sun shines directly. It should not be used as a roadside tree. It can be used as a landscape or courtyard tree, but it must be planted in a shady area. 2. ** Spring and autumn planting method (for small trees of about 3 cm)** - The best transplant area was in the plains of the northern border. The survival rate was very low in areas with slightly higher altitudes. When transplanting, the soil ball should be 10 times the diameter of the tree. It should be suitable for slightly acidic soil. When planting, it should not be buried too deep and should be consistent with the original planting depth. When planting, a small amount of fermented sheep manure (organic fertilizer) should be placed at the bottom of the pit to ensure the timely supply of water. 3. ** Soil treatment (if soil quality does not match)** - The soil was improved by changing soil in planting holes to make the PH value of the planting soil reach 5.0 - 7.0. It was mixed with organic fertilizer and slag to increase the nutrient content and breathability of the soil. As the white birch tree is not suitable for soaking, it needs 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; a net bag made of fine yarn net is used to fill wood chips, furnace slag, and fungus residue, so that water can be poured to the bottom when watering. The roots can fully absorb water and improve the survival rate. 4. ** Pillar Support ** - After planting it into the hole, the tree was straightened and slightly lifted up to make the root stretch, then filled with soil and stepped on. Build triangular supports, each triangular support forming a 120-degree angle. One end of the support is buried in the soil about 20cm (the depth can be adjusted according to the actual situation) and must be buried firmly. The other end is fixed at the first branch, and the three ends are firmly tied without hurting the bark. A layer of cloth can be wrapped at the binding place to protect the bark. ##5. Care 1. ** Watering ** - White Birch was a water-loving tree species. It needed to be watered frequently, but the amount of water needed to be strictly controlled. It should not be watered too much at one time, and attention should be paid to drainage. The first few watering can be combined with the application of the dilute solution of the iron sulphuric acid. After three consecutive penetrative irrigation, the application of the dilute solution of the iron sulphuric acid can be gradually reduced and the watering frequency can be reduced. After that, the normal management and protection can be carried out. 2. ** Trimming ** - It was not suitable to trim in spring to prevent bleeding. In autumn, it could be done by thinning and trimming dead and bad branches. After trimming, the cut should be treated and applied with wound smearing agent to prevent nutrients and moisture from evaporating and wound infection. 3. ** Fertility ** - After planting in spring and autumn, a small amount of organic fertilizer should be applied in the water weir and mixed evenly with the soil. After planting, within one year, circular or scattering nutrient ditches can be dug at 50cm around the root of the tree for fertilizer. In addition to winter, the application of potash fertilizer once a month could improve the resistance of transplanted seedlings, which was conducive to the growth of branches and leaves, making the bark smoother and whiter. 4. ** Sunscreen ** - During the hot summer, the white birch trees should be protected from the sun, such as covering the shade net or setting up micro-sprayers on the branches to cool down and moisturize. After transplanting, the white birch trees that had never been in the local summer should be sprayed with some anti-transpirant in the hot summer to meet their growth environment.

Birch trees were relatively easy to plant. White Birch trees were highly adaptable to soil. They liked acidic soil, were resistant to barren soil, and could adapt to lower temperatures. They could grow rapidly in an environment with sufficient sunlight, warm climate, and moist land (usually on slopes). It did not have high requirements for soil quality, and it was common to grow in mixed forests in the northern region. In terms of planting, it was necessary to make scientific planning as the guide. Starting from the local soil and climate characteristics, scientific investigation and research should be carried out according to their growth characteristics, and the planting area should be arranged reasonably. For example, when planting, priority should be given to half-slope land with high acidic soil; do a good job of soil and climate research; select good seeds, such as carefully selected seeds of better quality, soaking them in the seed soaking method (soaking for 24 hours), and then disinfecting them with chemical soaking method for about 2 days. When planting, pay attention to attaching a thin layer of suitable soil on the surface of the seeds. In terms of management, when using the transplanting method, one must pay attention to the climate and soil characteristics of the intended transplanted land. The transplanting method must conform to the growth characteristics of the tree itself. It must not be transplanted with "light roots" and ensure that the soil depth of the planting land is similar to the original growing land. The maintenance of the white birch trees was also relatively routine. In terms of watering, White Birch was a water-loving tree species, but the amount of water needed to be controlled. It should not be watered too much at one time, and attention should be paid to drainage. The first few watering could be combined with the application of dilute solution of Ferrous Sulphate, and then gradually reduce the application of dilute solution of Ferrous Sulphate and the frequency of watering. When trimming, it is not suitable to trim in spring to prevent bleeding. In autumn, it can be thinned and trimmed with dead and bad branches. After trimming, the cut should be treated. In terms of fertilizer application, after planting in spring and autumn, a small amount of organic fertilizer should be applied in the water weir and mixed evenly with the soil. After planting, circular or scattering nutrient ditches could be dug around the roots of the trees to apply fertilizer in different seasons. Except in winter, the application of potash fertilizer once a month could help improve the resistance of transplanted seedlings and the growth of branches. In addition, during the hot summer, sun protection measures should be taken, such as covering the sun with a shade net or setting up micro-sprayers on the branches. For the birch trees that have never been in the local summer after transplanting, anti-transpirant agents should also be sprayed. Although it was relatively easy to plant white birch trees, planting techniques still needed to be improved according to local conditions to ensure the normal development and high-quality growth of white birch trees.

Here are a few ways for children to draw a white birch tree: - One method was to use the method of cutting and scraping to represent the branches and trunk of the birch tree. First, he prepared white and black cardboard. He cut the white cardboard into long strips of different lengths with scissors, then stuck the long strips on the black cardboard with glue sticks to form trunks and branches. Then, he used the dry brush strokes of water chalk to draw the stripes on the trunks. Then, he prepared a blow-molded board, cut out the shape of the leaves, dipped it in gouache paint, and used rubbing to draw the shape and color of the leaves. Finally, he used ultra-light clay to make two birds and paste them in the picture to make the picture more lively and interesting. - You could also choose a piece of gouache paper, choose a fresh or contrasting color to paint the background color and paint the grass at the bottom of the picture. Dip the white gouache paint and draw the front, back, height of the birch tree trunk with long strokes. Dip the brown gouache paint with a small pen and add the tree grain and thin branches on the bark. Dip the green gouache paint and point the leaves around the branches with small strokes. Use different shades of green to point out the color changes of the leaves and use the length of the brush to represent the grass. You can also use gouache or light clay to represent the wildflowers on the grass. Finally, you can adjust the details of the picture to make the work more complete and beautiful.
