Problems solved by technology

In the process of corn planting, fertilization is one of the most important agricultural production measures. However, for a long time, excessive fertilization, single fertilization, and partial application of nitrogen fertilizer have caused problems such as soil nutrient imbalance, decreased fertilizer utilization rate, and agricultural environmental pollution.
The contribution rate of chemical fertilizers to crops is only about 30%. The more fertilizers are applied, the lower the utilization rate of fertilizers. Excess fertilizers remain in the soil, forming part of agricultural pollution: as rainwater flows into rivers and lakes, it will lead to eutrophication. ; Leakage into the groundwater will pollute the groundwater

Abstract

The invention discloses a compound disease-resistant microbial fertilizer special for corn. The compound disease-resistant microbial fertilizer is prepared from straw, corncob, wheat bran, plant ash, distillers' grains, shrimp shell meal, betaine, polyacrylamide, compound microbial bacteria, a leavening agent and brassinolide. The fertilizer provided by the invention can improve soil physical and chemical properties, enhance water retention, fertilizer retention and fertilizer supply capabilities of soil, and improve the absorption effect of corn on the fertilizer at the same time. The fertilizer can also effectively protect crops, reduce diseases and improve stress resistance such as disease resistance, insect resistance, drought resistance, cold resistance and the like of the crops. The fertilizer provided by the invention improves the number of seeds per ear, the weight of seeds per ear and the yield of seed production corn, and improves the resource utilization rate. The components are rich in oxygen, the raw materials are easy to obtain, preparation is simple, waste utilization can be achieved, pollution is reduced, and ecological environmental protection is promoted.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special compound disease-resistant microbial bacterial fertilizer for corn and a preparation method thereof. Background technique [0002] Corn is an annual herbaceous plant of the grass family Zea genus. Alternative names: maize, cob, corn, rice. Maize is an annual monoecious cross-pollinated plant with tall plants and strong stems. It is an important food crop and feed crop. It is also the crop with the highest total output in the world. Its planting area and total output are second only to rice and wheat. Corn has always been known as a longevity food, rich in protein, fat, vitamins, trace elements, cellulose, etc., and has great potential for developing high-nutrition, high-biological function foods [0003] Rust, sheath blight and leaf spot of corn crops are some common diseases in corn crops. The existing main control methods for these diseases are still traditional...
