The golden privet was an ornamental evergreen tree native to southern China. According to legend, it was the incarnation of a young girl. The girl loved to plant flowers when she was alive, so she was blessed by God and given the name of "Privet". Later on, she transformed into a tree and became the object of worship. The symbolic meaning of the privet tree was auspicious, longevity, beauty, happiness, and so on. In traditional Chinese culture, the privet tree was regarded as an auspicious thing, representing family harmony, smooth career, health and peace. In addition, it also symbolized hope and beauty. It was a symbol of people's pursuit of happiness and a good life. The golden privet was highly regarded because of its unique leaf color. Its leaves were golden yellow or grayish green, shining in the sun, very beautiful. In addition, it had small white or pink flowers and a long flowering period. It had high ornamental value. The golden privet was more tolerant of shade, but it liked a sunny and humid environment. The golden privet was suitable for cuttage reproduction. The cost of cuttage was low, and the survival rate was high. It was suitable for mass reproduction. The most suitable season for cuttage was after the Spring Festival. At this time, the climate was suitable, and the roots of the cuttage were better. The cultivation method of the golden leaf privet was relatively simple and had strong adaptability. It did not have strict requirements for the soil and grew well. The golden privet was widely used in the garden. It could be used to form patterns and build hedges. It could also be used for viewing in porches or halls. In addition, the golden privet also had medicinal value. It had the effects of convergence, diuretics, excitement, and could treat muscle pain and other symptoms.

The price of large-leaf white wax varied due to the origin, specifications, and other factors. The price range fluctuated greatly, ranging from 1 yuan/tree to 2980 yuan/tree. For example, in Cangxi County, Sichuan Province, 3.00 yuan/tree; Huimin County, Shandong Province, 1.00 yuan/tree; and there were large-leaf white wax landscape trees in Liaoning that cost 2980 yuan.

The following points needed to be paid attention to when planting and maintaining the golden privet. First of all, in terms of planting, the golden privet had strong adaptability and did not have strict requirements for soil. However, in order to grow better, it could be planted in loose and sandy soil. Before planting, the soil should be tilled and plowed, and the base fertilizer should be applied in the tree hole. For potted plants, they had to be planted with nutritious soil. Secondly, in terms of maintenance, the golden privet liked to be wet and drought-resistant. In the first year of planting, watering management should be strengthened, and it should be watered once or twice a month. In the summer, the amount of watering should be determined according to the rainfall situation. On rainy days, the accumulated water should be removed in time. After October, attention should be paid to controlling watering to prevent autumn hair. At the end of November, it should be watered with sufficient freezing water to facilitate the safe winter. In the early spring of the following year, they should be watered with thaw water. After that, they should be watered once a month. In July and August, they should also be managed according to the method of the first year. At the end of November, they should also be watered with frost water. From the third year onwards, watering would be determined according to the rainfall, but the water needed to be sufficient to thaw and freeze. In terms of fertilizer application, pen manure could be applied as base fertilizer during planting. After autumn, some decomposed and fermented sesame paste residue could be applied in combination with watering with frozen water. In the next spring, it could be applied with nitrogen, phosphorus and potash compound fertilizer. In addition, they had to pay attention to trimming the branches regularly to prevent the occurrence of pests and diseases, as well as provide a suitable temperature and humidity environment. Through reasonable planting and maintenance management, the golden privet could grow healthily and add green ecological value to the environment.

The following is a summary and reflection on the research report on the production of plant wax leaf specimens: ** I. Summing Up ** 1. ** Production process ** - ** Collection **: Pay attention to the completeness of the plants when collecting. Try to collect the complete plants of short herbs, including roots, stems, leaves, flowers, and fruits. Tall plants can be collected in sections with corresponding parts. After the collection, a label number must be hung, and the information such as the person who collected it and the time and place must be recorded. - ** Suppression of specimen **: Before suppression, clean up and remove rotten leaves, residual leaves, and soil at the root. The specimens were placed on papyrus paper, arranged so that the leaves could be unfolded, and the flower parts could be covered with toilet paper to prevent sticking. Then, the specimens were separated with cardboard and wavy aluminum plates, and then fixed with splints. - ** specimen drying **: The drying methods include natural drying and drying. Natural drying was to change the straw paper every day to absorb water, which was affected by the weather temperature and humidity and took a long time. For drying, small dryers, air warmers and other equipment could be used. Corrugated aluminum plates could make the specimens evenly heated, which was suitable for large-scale production of specimens in school laboratories. - ** Binding of specimen **: Requires paper, scissors, a utility knife, a pen, and other tools. Take the dried specimen from the papyrus and place it on the table paper. It can be placed in different positions. If it exceeds the size of the table paper, it can be folded. Mark the fixing point with a pencil, carve a slit, and fix it on the back with glue. You can also glue it directly. - ** specimen information **: The bound specimen must be attached with a collection label and identification label, including the date of collection, location, altitude, living environment, plant height, breast diameter, leaves, flowers, fruits and seeds, Chinese name, family name, scientific name, economic value, and other information. 2. ** The significance of wax leaf specimens ** - ** Plant classification **: Wax-leaf specimens are an important tool for plant classification. Botanists can use a large number of wax-leaf specimens to describe and identify plants, which is not limited by seasons and regions, and has promoted the development of plant classification. - ** Production feasibility **: The production of wax leaf specimens does not require complex chemical reagents and professional equipment. It is suitable for family production and can be used as a parent-child activity. The production materials are easy to obtain, such as using newspapers instead of papyrus, books instead of splints, etc. 3. ** The difference between a wax leaf specimen and a dried flower ** - ** Different purposes **: Wax-leaf specimens focus on plant integrity and biological information display. They do not pursue beauty and generally do not undergo dyeing and other processing. Dried flowers are for decorative purposes and pursue color and shape beauty. They have no scientific research value. - ** The difference in the production process **: The wax leaf specimen has a pressing process. The dried flowers are naturally dried or dehydrated with silica gel during the dehydration process, which can maintain the three-dimensional shape. For example, the baby's breath and forget-me-not are suitable for natural drying to make dried flowers. ** 2. Reflection ** 1. ** Problems in the production process ** - ** Problem with specimen preservation **: Even if careful work such as dust removal, disinfection, fixing, and moisture absorption were done during the production process, the specimen may still have problems such as yellowing, moldy, falling leaves, and long insects. This reflected the need to further explore better methods for specimen preservation, such as improving the humidity and temperature control of the storage environment, or finding more effective anti-insect and anti-mold agents. - ** Pressing and drying **: During the pressing process, some specimens may not be completely flat or dried unevenly. This may be related to the materials used (such as the water absorption of the paper, the thermal conductivity of the wavy aluminum plate, etc.) and the details of the operation process (such as the frequency of changing the paper, the density of the specimen, etc.). He needed to further improve the operational standards of these links. 2. ** Exhibition **: After the specimen is made, a better method of presentation is needed so that more people can intuitively obtain knowledge from the specimen. This might involve the design of the exhibition space and the innovation of the exhibition tools. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The breeding methods and precautions of the golden leaf privet included the following points: 1. Light and temperature: The golden privet likes plenty of sunlight, so choose a place with plenty of light. It was not resistant to high temperatures, but it had strong cold resistance. It could be maintained in a sheltered place with a better climate to keep its leaves from falling. 2. Water and fertilizer: Golden privet was afraid of waterlogging, so it was necessary to pay attention to drainage on rainy days to avoid long-term soaking of its roots in water. Water the soil frequently during drought to keep it moist. When applying fertilizer, pay attention to the reasonable combination of nitrogen and phosphorus fertilizer to promote the growth of saplings and avoid excessive application of nitrogen fertilizer. 3. Trimming and cleaning: Spray disinfectant immediately after trimming to prevent the saplings from getting infected. Try to avoid trimming during the rainy season. At the same time, they had to clean up the weeds and other debris in the plantation in time to prevent the breeding of pests and diseases, which would affect the growth of the saplings. 4. Pest control: Golden privet has strong disease resistance and few pests. However, after the hedges were formed and the ventilation was poor, they could start spraying in the spring to prevent pests and diseases. Commonly used pesticides included rapid-kill and scale-kill, while antimicides included carbendazim, cyanothalonil, thiophanate, etc. To sum up, the cultivation methods and precautions of the golden privet included providing sufficient light and suitable temperature, paying attention to the reasonable control of water and fertilizer, regular trimming and cleaning, and preventing pests and diseases.

Waxing jade was the last step of jade processing. There were several waxing methods: 1. Wax Steaming (Wax Steaming): Put the jade into a steamer, heat it up, and sprinkle wax powder on it. The wax will melt and cover the jade. This method only works on the naturally formed shallow cracks on the surface. 2. ** Boil wax **: First melt the wax and keep it at a constant temperature. Put the jade into a sieve-shaped flat-bottom container and immerse it in the melted wax. After a few hours, take it out and shake off the excess wax and remove the surface wax. This method could go deep into the interior and cover the cracks and deep hidden cracks, increasing the value of the jade. It was more common in the jade industry. 3. For waxing jade, one was to soak the jade in melted liquid wax, and the other was to heat the jade slightly, spray white wax powder on it, and then wipe it with a rag to let the wax soak into the tiny cracks. 4. ** In terms of waxing Hetian jade **: - [Solid wax: Solid wax is commonly used. There are steaming, fire roasting, and heating with a hairdryer.] For example, the hair dryer heating method, first clean and dry the jade, then use the hair dryer to blow it hot (about the degree of scalding), sprinkle a little solid wax powder (fine particles), brush it evenly with soft hair, and then wipe it with a cotton cloth to brighten it. The advantage of solid wax was that it was not easy to dirty the jade when playing with it, but it was easy to turn yellow and difficult to remove after turning yellow, which might damage the jade quality. - [Liquid Wax: A simple, convenient and widely used waxing method for Hetian jade.] First, clean the Hetian jade (you can add a small amount of cleaner and brush it with a toothbrush), dry it with a hairdryer until it is warm to the touch, and then use a brush to dip in the liquid wax to brush it once. Waxing could make jade more transparent and shiny, cover up flaws, and make jade more beautiful. It could prevent the jade from cracking and maintain its smoothness. It was a common optimization method recognized by the industry and national jewelry standards. However, after a period of time, the wax would evaporate and disappear, and the cracks on the jade might reappear. You could tell if the jade was waxed by soaking it in slightly cooled boiling water for a few minutes and then wiping it. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

In the maintenance of jewelry and jade, wax was a commonly used maintenance material. For example, jadeite must be waxed in the final polishing process. This process was recognized as a "traditional and widely accepted method of optimization to show the potential beauty of jewelry and jade." For the maintenance wax of jade and other jade, Sichuan wax was a commonly used wax. It was a white insect wax produced in Sichuan Province. It was an organic substance secreted by white wax insects that parasitized on privet trees or white ash trees when they laid eggs and built nests. It formed a crystallized organic protective film on the surface of jade. There were also products such as jade polishing and repairing wax, jade agate boiled Sichuan wax, etc., which were used to wax gemstones. There were also grade 1 solid wax for mirror light maintenance. The melting point of this kind of wax was 60, the oil content was 80, and the appearance was a block wax. The color was white and tasteless. During the jade maintenance process, wax can protect its surface luster, color, and hardness, avoid oxidization with oxygen and impurities in the air, reduce scratches and wear, and extend the life of the jade. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
