The function and application method of the automatic mounting-cluster agent for ripe silkworms
(1) Brief introduction "Automatic mounting-cluster agent for ripe silkworms" is a new type of silkworm medicine that promotes uniform maturity of silkworms and automatic mounting of ripe silkworms onto clusters; at the same time, unripe silkworms, diseased silkworms and weak silkworms do not climb onto the clusters, improving cocoon quality and reducing the rate of inferior cocoons. (2) Advanced nature of the technology "Automatic mounting-cluster agent for ripe silkworms" passed appraisal organized by the Guangdong Provincial Higher Education Bureau in 1993, and experts unanimously considered that the result reached the domestic leading level. In China, molting hormone is used to make silkworms mature uniformly; when they are ripe, they are picked up one by one by hand and placed on clusters, or unripe and ripe silkworms are picked up together with both hands and placed on clusters.

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,

What are the precautions for using pear fruit swelling agent?
Pear fruit swelling agent is a plant growth regulator developed and utilized in recent years. Its effect is to promote fruit cell enlargement, especially when used on early and mid-season pears, where the swelling effect is obvious. However, improper use of pear fruit swelling agent will not only fail to achieve the ideal effect, but also cause side effects. Therefore, for pear trees using swelling agent, water and fertilizer must be kept up, especially full-element chemical fertilizers, to ensure sufficient nutrients to meet the needs of fruit growth and development, so as to achieve the ideal effect. In addition, harvest at the right time

How is reagent-grade starch made from potatoes?
Using potatoes, reagent-grade starch can be produced with low cost and high economic benefit. Production method 1. Washing and making potato pulp: Wash the potatoes with water 2 to 3 times, remove all mud and sand, and cut away potato pieces with hoe injuries and rotten holes. Start the crusher, feed in the washed potato pieces, and the potato pulp will flow out immediately. Because fresh potatoes themselves contain about 75% water, no additional water is needed when pulping. 2. Filtering the pulp and rinsing the starch: Filter the potato pulp by machine or by hand, and store the starch milk (water containing starch) in a tank to clarify. Wait for the starch in the tank to settle to the bottom
