Disease-resistant fertilizer special for corn

Abstract

A disclosed disease-resistant fertilizer special for corn is prepared as follows: utilizing bacillus subtilis to perform fermentation on rapeseed cake, wheat bran, plant ash, animal manure and pond sludge, so as to obtain a fermentation material; fusing urea, then adding ferrous sulphate, monoammonium phosphate, diammonium phosphate, boric acid, potassium chloride, zinc sulfate, a magnesium-potassium sulfate fertilizer and ammonium molybdate, mixing uniformly, cooling, uniformly mixing with the fermentation material to obtain a material A; uniformly mixing the material A, Chinese medical stone, a soil improvement composition bamboo charcoal, oil shale ash and attapulgite powder, crushing and sieving to obtain the disease-resistant fertilizer special for corn. The disease-resistant fertilizer special for corn helps to improve the lodging resistant capability of corn, satisfies various element demands by corn growth, has a release speed satisfying different demands of corn at all growth stages on nutritional elements, also is capable of improving soil physical and chemical properties and increasing soil fertility, and also is capable of preventing attack of sclerotinia rot and avoiding large-area output reduction.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special fertilizer for disease-resistant corn. Background technique [0002] Corn is the main food crop in my country. Corn needs a large amount of fertilizer. Scientific and rational fertilization is an important aspect of high-quality, high-yield, and efficient development of corn production. After ordinary fertilizers are applied to the soil, due to the short fertilizer effect period, topdressing is required in the later stage. Spring corn areas in my country generally start sowing at the end of April and harvesting in October, with an average yield of 500 kg. However, with the increase in fertilization in recent years, although the yield has increased, the soil fertility has declined at the same time, the soil has hardened, and the bottom of the plow is getting worse.

Problems solved by technology

Spring corn areas in my country generally start sowing at the end of April and harvesting in October, with an average yield of 500 kg. However, with the increase in fertilization in recent years, although the yield has increased, the soil fertility has declined at the same time, the soil has hardened, and the bottom of the plow is getting worse. Shallow, corn lodging is very serious in the late stage. Although the country strongly advocates the use of organic fertilizers to improve the soil and improve the plow layer environment of the soil, but because organic fertilizers are troublesome to use, the amount of application is large, and the cost of labor input is too high, farmers do not use them now. They are willing to use organic fertilizers, so farmers now use a large amount of inorganic fertilizers. It is precisely because of the extensive use of inorganic fertilizers that the soil is compacted and the soil structure is destroyed.

At present, it is urgent to find a way to achieve the best of both worlds. On the one hand, it can meet the needs of high-yield fertilization, and on the other hand, it can improve the physical and chemical properties of the soil to achieve the purpose of improving the soil. It is also necessary to strengthen the lodging resistance of corn, and corn is often easily infected by bacteria. Nuclear disease, which caused a large area of ​​production reduction
