Why does over-applying nitrogen fertilizer reduce crop yields, and how much nitrogen is actually needed?
Nitrogen is one of the essential nutrient elements for crops, and supplying nitrogen fertilizer in appropriate amounts can increase crop yields and improve quality. But if nitrogen fertilizer is over-applied, crops will instead reduce yields. What is the reason for this? How much nitrogen do crops actually need? Over-applying nitrogen fertilizer causes the carbohydrates produced by crop photosynthesis

How to grow Angelica dahurica to reduce bolting and achieve high yields
In production, some Angelica dahurica plants often bolt and flower prematurely in the second year, generally 10%-30%, and in some cases more than 50%, seriously affecting yield and quality. There are many factors that cause bolting and flowering in Angelica dahurica. In view of bolting in Angelica dahurica, the following measures are mainly taken: according to the

Why do continuous and alternating soybean cropping reduce yields? Cause analysis and countermeasures
With China's accession to the WTO and the opening-up policies of the grain market, the problem of continuous and alternating soybean cropping has become increasingly serious, and the yield reduction increases as the number of consecutive cropping years rises. According to surveys and research, alternating cropping reduces yield by 6.1%, one year of continuous cropping by 9.9%, two years of continuous cropping by 13.8%, and three years of continuous cropping by 19.0%. Moreover, in continuous and alternating cropping soybeans, the 100-seed weight decreases, the rate of diseased seeds and insect-damaged seeds increases, and commercial quality drops significantly. With long-term continuous cropping of more than 3 years, the protein content of soybeans increases markedly while the fat content decreases markedly. According to research by scientific research departments

Early prevention and control of soybean diseases: seize the opportunity to reduce yield losses
To achieve high yields in soybean, the main challenge is to properly manage the four aspects of "seed, water, fertilizer, and light." The "deep-narrow-dense" cultivation technique is a comprehensive high-yield supporting cultivation model formed on the basis of this principle. It takes the selection of dwarf varieties as the breakthrough point, uses air-suction seeders and general-purpose machines as the carrier, and combines "deep" (i.e., deep loosening, deep fertilization, and layered fertilization), "narrow" (i.e., narrow rows), and "dense" (i.e., increased planting density) into a comprehensive high-yield supporting technique. It is a cultivation technique that uses large seeders as the carrier. "Seed" means variety,

Using the right corn growth regulator can increase yield, but using it wrong will reduce yield
Will an excessive amount of corn growth regulator cause a reduction in corn yield? I can tell you clearly: it absolutely will. The problem of using too much growth regulator does not only occur in corn; it also happens frequently in peanuts, wheat and rice. In production, the...
