Application method for potash fertilizer

Abstract

The invention relates to an application method for potash fertilizer. The application method for the potash fertilizer is characterized by comprising the following steps: sampling to-be-fertilized land so as to obtain a soil sample; preparing a liquid soil medium from the soil sample; culturing silicate bacteria with the liquid soil medium so as to obtain a culture solution; measuring the content of rapidly available potassium in the culture solution; and applying the potash fertilizer and silicate bacteria fertilizer according to the content of rapidly available potassium and demands of the to-be-fertilized land for potassium. The application method for the potash fertilizer is beneficial for reasonable fertilization.

Description

technical field [0001] The invention relates to a fertilization method of potassium fertilizer. Background technique [0002] Plant growth needs a lot of nitrogen, phosphorus, potassium and other elements. With the increase of chemical nitrogen fertilizer and potash fertilizer, the lack of straw returning to the field and the loss caused by rain erosion, the excess nitrogen fertilizer and insufficient potassium fertilizer in the plow layer have become an important problem in agricultural production. Soil nutrients are out of balance, and potassium-deficient areas continue to expand. Insufficient potassium in soil has constituted a limiting factor for increasing crop yields and improving varieties in my country. Therefore, the application of mineral potassium fertilizers in agricultural production is increasing. However, my country lacks potash resources and mainly relies on imports, resulting in high potash fertilizer prices. Insufficient potassium fertilization will affec...

Problems solved by technology

However, our country lacks potash resources and mainly relies on imports, resulting in high potash fertilizer prices.

Insufficient potassium fertilization will affect the yield of crops, but blindly applying a large amount of potassium fertilizer will cause waste of resources and increase costs on the one hand. On the other hand, a large amount of potassium will form insoluble or insoluble potassium compounds in the soil, which cannot be absorbed by crops. And it is not conducive to the protection of agricultural ecological environment
