Disease-resistant compound biofertilizer special for corn and preparation method thereof

Abstract

The invention belongs to the technical field of fertilizer, particularly relates to disease-resistant compound biofertilizer special for corn and further relates to a preparation method of the disease-resistant compound biofertilizer special for the corn. The disease-resistant compound biofertilizer special for the corn comprises carbamide, compound microbial agents, bran, chitosan, furfural residues, ammonium sulfate, potassium sulfate, monoammonium phosphate, rape seed cakes, manure, humic acid, sesame seed cakes, microelements, calcium superphosphate and plant ash. The nutrient elements of the disease-resistant compound biofertilizer special for the corn are balanced, microelement compositions are abundant, soil productivity and soil fertility can be improved effectively, addition of compound microbial agents can remarkably restrain main corn diseases occurring universally, the disease-resistant compound biofertilizer special for the corn is long in fertilizer efficiency, corn yield can be improved by 25 to 30 percent effectively, the corn diseases can be prevented and cured effectively, soil can be improved effectively through long-term utilization of the disease-resistant compound biofertilizer, and the disease-resistant compound biofertilizer special for the corn can play a role in the whole growth period of the corn.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a special disease-resistant compound microbial bacterial fertilizer for corn, and also relates to a production method of the special disease-resistant compound microbial bacterial fertilizer for corn. Background technique [0002] Corn can be used as food, feed and industrial raw materials. It is planted in a wide range in my country. According to different natural conditions, it is divided into several major corn areas. troubled. [0003] In recent years, due to the serious phenomenon of heavy use of farmland and low cultivation, the quality of cultivated land has shown a downward trend, which is mainly manifested in soil degradation, shallow plow layer, water and fertilizer retention, and reduced ability to resist diseases and insect pests. In order to deal with this situation, inappropriate repeated use of pesticides and fertilizers , Excessive application has ...
