Soybean molecular breeding technology successfully developed by South Korea
The Agricultural Biotechnology Research Institute of South Korea's Rural Development Administration recently successfully developed a soybean molecular breeding technology, which means that South Korea's mass production of organic soybeans containing anti-cancer components will become a reality. South Korea's regeneration technology for soybean plant bodies through tissue culture is not well developed, so trait-transformed soybeans are mainly imported from the United States. The Rural Development Administration revealed that molecular breeding technology is called third-generation genetic engineering technology. Using this technology, soybeans with higher added value can be produced, which is of great significance for increasing farmers' income.

How can cotton be given base fertilizer skillfully to increase yield?
For base fertilizer in cotton fields, first, apply more organic fertilizers of various kinds, or bio-organic compound fertilizers; second, achieve formula fertilization and balanced fertilization, applying nitrogen, phosphorus and potassium in a ratio of 3:1:3; third, for insect-resistant cotton, apply more potassium fertilizer, with no less than 15 kg per mu as base fertilizer, plus 0.5-0.7 kg of zinc fertilizer and 0.4 kg of Chilibor; fourth, apply fertilizer in an appropriate amount, and do not blindly pursue quantity; applying 25-30 kg per mu of high-content ternary compound fertilizer is sufficient; fifth, change broadcast application to furrow application or hole application, and the cotton seedling roots should maintain

How to Apply Fertilizer Skillfully to Cotton? A Explanation of Practical Technical Points
Fertilizer is the material basis for high cotton yields, and applying fertilizer according to need is the highest principle of cotton fertilization. Where conditions allow, soil testing and fertilizer recommendation should be carried out, and based on the available nutrient content of the soil and the needs for high cotton yields, the type and amount of fertilizer to apply should be determined. For most cotton fields in the north, the amount of potassium fertilizer should be increased, the amount of phosphorus fertilizer reduced, and nitrogen fertilizer mainly used for topdressing, or a formula fertilizer with "high potassium, low phosphorus, medium nitrogen" should be applied. If a compound fertilizer with equal amounts of nitrogen, phosphorus and potassium is used, the amount per mu should not exceed 25 kg, plus an additional 12.5 kg of potassium fertilizer
