Compound microbial fertilizer for improving lodging resistance of crops

Abstract

The invention designs a microbial fertilizer. The composite microbial fertilizer comprises the following components in parts by weight: 10-30 parts of a microbial agent, 35-60 parts of potassium humate, 1-3 parts of a soil conditioner, 1-2 parts of a water-retaining agent, 45-80 parts of industrial starch waste and 0.5-1 part of a soil active enzyme. The microbial agent is prepared from two or more of bacillus megatherium, bacillus licheniformis, actinomycete flora and photosynthetic bacteria; the soil conditioner is composed of compound sodium nitrate and naphthylacetic acid; wherein the industrial starch waste is one or two of corn starch waste and potato starch waste. The composite microbial fertilizer disclosed by the invention can improve the soil structure and promote the growth of soil effective microbial communities so as to continuously improve the soil environment; moreover, the plant stems of the crops can be thick and strong, and the lodging resistance of the crops is further improved.

Description

technical field [0001] The invention relates to the technical field of microbial fertilizer, in particular to a compound microbial fertilizer for improving crop lodging resistance. Background technique [0002] Lodging refers to the situation in which vertically growing crops are skewed in pieces, and even the whole plant is prostrate on the ground. Lodging can reduce the quality of crops and reduce their yield. Lodging mostly occurs in the later stages of crop growth. There are many reasons for lodging , one of which is that the root system of the crop is shallow, resulting in poor nutrition of the crop stem, and the whole is not strong enough to support the ear of the crop, and soil compaction is one of the reasons for the shallow root system of the crop. One of the main reasons is the excessive use of nitrogen fertilizer and insufficient nutrient distribution of crops, resulting in excessive growth of crop stems, and insufficient fiber strength of stems, resulting in frag...

Problems solved by technology

[0004] 1. The use of crop growth regulators such as chlormequat alone cannot fundamentally solve the problem of land retention, and long-term use of such regulators will make the soil rich in such regulators. If it is replaced with other crops, its effect It may have the opposite effect. For example, the use of chlormequat in carob seedlings will affect the growth of carob vines, resulting in a relatively thick and short seedling, which will reduce the yield of carob;

[0005] 2. Using soil conditioners and microbial flora, the effect of improving the soil can only last for a short period of time, and cannot achieve the effect of continuously improving the soil
