Abstract

The invention relates to a compound fertilizer special for corn and a preparation method thereof, and belongs to the field of crop fertilizers. The compound fertilizer special for corn is prepared by silkworm excrement, vinasse, fulvic acid, fermented bean dregs, broomcorn, a peanut cake, a corn straw fermenting liquid, gelatin, urea, diammonium phosphate and potassium sulphate through a special method. Different components in the fertilizer are released according to a certain sequence, so that the demand for different elements in different growth stages of soybean is satisfied, and the growth rhythm of soybean is met. Therefore, yellow leaves in the initial growth stage can be avoided, and strain collapse in the mature stage can be avoided. Meanwhile, the yield and quality of corn are further effectively improved, so that the content of trace nutritional ingredients is higher so as to better meet the dietary standard of modern people.

Description

technical field [0001] The invention relates to a special compound fertilizer for corn and a preparation method thereof, belonging to the field of crop fertilizers. Background technique [0002] my country is a large agricultural country. Chemical fertilizers and pesticides play a very important role in the agricultural production process. With the improvement of people's living standards and health awareness, people attach great importance to the safety of agricultural products, and the demand for pollution-free and green food is increasing year by year. Increase. Corn is the main crop in my country; currently there are many types of fertilizers used for corn planting, and most of the special fertilizers for corn are NPK compound fertilizers available on the market, especially controlled-release fertilizers. However, the existing controlled-release compound fertilizers dedicated to corn have the problems that the release rate of the fertilizer does not match the growth requ...
