Yingbuluo Nanguo Pear Builds Its Brand Through Scientific Management
1. Fruit tree pruning: Through winter pruning and spring pruning, the fruiting branches are spread out and an umbrella-shaped canopy is formed to achieve ventilation and light penetration. Pay special attention to summer pruning (mid-summer pruning), removing all water sprouts, back branches and new shoots from mature fruit trees, reducing waste of tree nutrients, maintaining the canopy in a moderate state, and ensuring that all nutrients produced by the leaves are effectively used for fruit growth and tree development. 2. Applying farmyard manure: Farmyard manure has a complete range of nutrients and is the most ideal fertilizer for improving fruit quality. Bao Dianhong's orchard applies farmyard manure once every two years, with 200-250 kg of fully decomposed farmyard manure per tree, plus some chemical fertilizer each year. He believes that doing so can both keep the tree vigorous and control excessive tree growth that causes canopy shading, ensuring fruit coloration and improving fruit quality.

Detailed Explanation of Drought Prevention and Drought Resistance Technical Measures for Tea Seedlings
Whether a newly developed improved-variety tea garden can achieve full stands, uniform seedlings and grow well into a mature plantation depends first and foremost on whether it can safely pass through the summer-autumn drought period. This year's climate is quite unusual; just after the plum rain ended, the scorching sun hung overhead, and since early July there has been continuous high temperature, with some districts and counties experiencing 38°C-39°C for 7-8 consecutive days, severely threatening the growth, development and survival of tea seedlings. In our city, tea seedlings are most easily killed by sunburn in July and August, so how to do a good job in drought prevention and drought resistance for seedlings is crucial. Six aspects must be achieved: "shade", "cover", "irrigate", "fertilize", "

Biological agents developed for pest and disease control throughout the goji growing season
With the creation of 4 compound pure biological agents formulated by the "Research on Biological Control Technology for Major Goji Pests and Diseases" team at the Institute of Plant Protection of the Ningxia Academy of Agriculture and Forestry Sciences, the pests and diseases constraining the development of Ningxia's goji industry have finally met their greatest "natural enemy." The use of these agents will achieve biological control of pests and diseases throughout the entire goji growing season, not only reducing the number of control applications but also improving goji quality. Goji is a traditional medicinal herb cultivated in Ningxia and is also a leading industry designated by the autonomous region's Party committee and government. However, the occurrence of goji pests and diseases is extremely complex,

Detailed Explanation of the Fertilizer Requirement Patterns of Lilies Throughout the Growing Period
Understanding the fertilizer requirement patterns of lilies at each growth stage is very beneficial for rational fertilization and promoting high yields. The patterns of lily demand for the three major nutrients: 1. Nitrogen fertilizer: The nitrogen absorption rate of lilies varies at different growth stages. At emergence, the nitrogen absorption rate is 3.5537 probit units, and the cumulative nitrogen absorption percentage is 7.4%, equivalent to 0.201 kg of nitrogen absorbed per mu. This indicates that during the seedling stage, in addition to receiving nutrients from the mother bulb, the plant also needs to absorb a certain amount of nitrogen from the soil. 2. Phosphate fertilizer: At emergence, the phosphorus

Monsanto's drought-tolerant GM cotton variety to be launched soon
Monsanto, the world's leading seed company, is developing a drought-tolerant genetically modified cotton variety that could be launched for commercial cultivation by 2015. Jerry Steiner, vice president of Monsanto, said: "We hope to launch a drought-tolerant cotton seed by the middle of the next decade. But five years from now, we will be able to announce whether we can launch drought-tolerant seeds by that time." Monsanto officials also said the company is currently researching genetically modified seeds that can minimize fertilizer use. Genetically modified seeds

How to Add Value to Sweet Potato and Rice Through Processing
Sweet Potato Starch Production Technology Wash the sweet potatoes, drain the water, crush them into pieces about 2 cm in size with a crusher, feed them into a stone mill or electric pulp grinder, add 3 to 3.5 times their volume of water, and grind into a starch slurry. Pour the starch slurry into a sieve with a mesh size of 60 and sieve out the potato residue to obtain starch milk. Place the starch milk in a settling tank and let it stand overnight so that the starch settles to the bottom of the tank. Drain off the supernatant, take out the crude starch, repeatedly rinse and settle it with clean water to obtain pure starch, then sun-dry, crush and sieve the starch to obtain

What is ground bed cultivation of Gastrodia elata? Let us walk you through this cultivation method
In low-lying flat land with a high water table, relatively low temperatures, and damp, rainy conditions, or when cultivating Gastrodia elata on a small scale in a new area, this planting method can be used. Bed cultivation is also divided into two methods: single-layer planting and double-layer planting. ① Single-layer planting method: Level the ground and make a bed 60-70 cm wide; the bed length depends on the terrain and the amount of Gastrodia elata to be planted. On the leveled bed surface, first spread a 2-3 cm thick layer of base culture material, then lay the fungus logs horizontally with a spacing of 6 cm. On both sides of the fungus logs, first add culture material up to half the height of the logs,

What Is Osteochondrosis in Dogs? Let Us Walk You Through This Disease
Osteochondrosis is a disease characterized by bone necrosis and impaired bone development in young dogs that are still in the growth and development stage. Examples include osteochondritis dissecans of the shoulder joint, osteochondrosis of the elbow joint, ununited anconeal process, and osteochondritis dissecans of the knee joint. [Causes] The cause is not yet clear. It is generally believed that the direct causes are circulatory disturbances or excessive traction and compression trauma. Endocrine dysfunction, malnutrition, and genetic factors are also related to the occurrence of this disease. [Symptoms] Osteochondritis dissecans of the shoulder joint is more common in large

New breakthrough in the treatment of self-biting syndrome in foxes, raccoon dogs and minks
Self-biting syndrome is a common disease of captive fur-bearing animals such as foxes and minks. In recent years, it has occurred in many farms and households in China, causing great economic losses. There had been no specific prevention or treatment measures for this disease, and the key point was that the cause had not been identified. Regarding the cause, people had put forward many hypotheses or claims, but these had not truly served to guide prevention and treatment. Since the early 1990s, researchers have carried out some research work on the cause of the disease. In the course of research and experiments, the cause of self-biting syndrome was identified,

What are the advantages of cultivating Gastrodia elata in indoor bed frames and troughs?
① Cultivating Gastrodia elata on indoor bed frames makes temperature and humidity easy to control, and it is not affected by heavy rain, drought, extreme heat, and so on. Indoors, there is good shading, and if water is lacking, it can be sprayed or watered, allowing for high and stable yields. ② The growth period of Gastrodia elata lasts as long as 300 days, with a high multiplication rate and a large weight-gain multiple. ③ It can effectively use the space area and can also save part of the wood (compared with box cultivation). Especially when iron frames are used for cultivation, the bed frames can be used for a long time. ④ It facilitates the prevention and control of pests and diseases, is easy to manage, and occupies less cultivated land.
