Fertilization Methods for Gastrodia: Can Diammonium Phosphate, Superphosphate, and Ammonium Nitrate Be Applied?
Yes, they can be applied. This is because all three fertilizers are acidic fertilizers and can increase soil acidity. In terms of their properties, they suit the growth and development requirements of Armillaria mellea and Gastrodia; in terms of composition, all three fertilizers contain phosphorus and nitrogen components; in theory, Armillaria mellea requires a certain amount of phosphorus and nitrogen during its growth and development. During the growth and development of Gastrodia, as it absorbs water from the substrate, it can take up some trace elements and phosphorus along with the water. Therefore, when cultivating Gastrodia, applying an appropriate amount of acidic fertilizer can increase Gastrodia yield. According to Dan Cunzhi and Wang Yingkui, Gastrodia specialists in Wangjiayuan Village, Siping Township, Danfeng County, Shanxi Province

How is pig artificial insemination technology applied in rural areas
Farmers raising sows in a free-range way can not only make full use of leftover food scraps, but also increase the family's economic income. Especially with the construction of rural biogas pits in recent years, in order to produce sufficient biogas, each household has expanded from raising one or two pigs to eight or nine pigs now. This makes timely breeding of sows in heat a problem. In the past, rural areas mostly used natural mating, bringing in someone else's boar or taking the sow out. Transporting pigs back and forth is very inconvenient, and it is also bad for disease control. Thinking from a different perspective, if others raise sows and I specialize in raising breeding boars, building a small boar station to serve the surrounding

Why must organic fertilizer be applied continuously for sustained high cotton yields?
Although cotton is a relatively tolerant crop when it comes to poor soil, achieving high and stable yields requires cotton fields to have fairly high fertility. According to measurements by the Cotton Research Institute of the Chinese Academy of Agricultural Sciences, most cotton fields nationwide currently have insufficient fertility, and the levels of various nutrients vary widely and are very unbalanced. This is especially true in the cotton region of the Yellow River basin, where organic matter content is low, nitrogen supply is insufficient, available potassium content is declining rapidly, and the trace elements zinc and boron are also in the deficient or potentially deficient range. These have become important factors restricting the sustained and stable increase of cotton yields. Cotton is a deep-rooted crop, and its growth

Why should fertilizer be applied promptly after cotton topping?
After cotton topping, it is the time when the various organs compete most intensely for nutrients. The development of young bolls after flowering requires nutrients, the enlargement of buds and flowering require nutrients, and the elongation of the upper fruiting branches and the growth of new leaves and flower buds require nutrients. If the nutrient supply is insufficient, either the boll set in the middle and lower parts decreases, or there are no bolls in the upper part, or after boll setting the plant prematurely ages, leaves drop, and boll weight decreases, none of which can achieve the goal of high yield. Therefore, supplementation should be carried out promptly by combining root-zone fertilization with foliar spraying, mainly with nitrogen and potassium fertilizers, and appropriately applying phosphorus fertilizer on phosphorus-deficient soil.

Rice straw return technology is being vigorously promoted and applied.
Vigorously promoting rice straw return is one of the most economical and effective ways to recycle nutrients through the soil-crop-soil cycle. It not only plays a very important role in improving soil and building up soil fertility, but also has great significance for improving soil potassium and silicon nutrient conditions, balancing crop nutrition, and alleviating the contradiction between the shortage of potassium fertilizer resources in our country and the excessively rapid rise in chemical fertilizer prices. 1. Increasing soil organic matter content. Rice straw has a high organic matter content. Generally, dry rice straw has an organic matter content of 40%. After being returned to the field, it is beneficial to the

How do vegetables get nitrogen fertilizer applied? Signs and dangers of excessive nitrogen fertilizer
It is worth noting that nitrate ions, upon contact with digestive enzymes in saliva, are converted into nitrosamines, a chemical compound that the medical community has confirmed to be a carcinogen. Therefore, Professor Zheng Zhengyong reminds the public that just as the Department of Health encourages children to eat more fruits and vegetables, they should also
