Problems solved by technology

[0002] With the growth of the population, in order to meet the needs of food, the amount of chemical fertilizers in my country is showing a continuous growth trend. The application of chemical fertilizers has made a great contribution to solving the problem of food shortages. The destruction of the balance also causes soil compaction, which sharply reduces the beneficial microorganisms in the soil, reduces the permeability of the soil, the ability to supply oxygen, and the ability to maintain nutrient balance. Absorption changes the soil structure, resulting in poor growth and quality of crops, and various diseases are becoming more and more serious. At the same time, the increase of pesticide residues in plants seriously threatens human health and safety.
[0003] With the development of green agriculture, the application of biological fertilizers or biological compound fertilizers in agricultural production has attracted more and more attention. At present, most countries use compound fertilizers as base fertilizers and additional fertilizers. Among the three major elements of phosphorus and potassium, nitrogen lacks slow-release and controlled-release technology, and thus loses the stable balance between nitrogen and phosphorus and potassium.
Nitrogen has a short validity period and a large amount of loss during use, so it is necessary to topdress nitrogen fertilizer in the middle of crop growth. The operation of topdressing fertilizer is time-consuming and laborious, which is not commensurate with modern agricultural production with high efficiency and simplified operation

Abstract

The invention relates to an agricultural fertilizer, in particular to a microbial compound fertilizer and application thereof. The microbial compound fertilizer specifically consists of a zymophyte agent and a compound fertilizer, wherein each gram of the compound fertilizer comprises not less than 0.2*108 bacterial cells; the compound fertilizer comprises the following components in percentage by weight: 5 to 15 percent of farmyard manure, 10 to 30 percent of humic acid, 5 to 8 percent of grass carbonic acid, 15 to 30 percent of nutrient and the balance of boric sludge; and the zymophyte agent is obtained by fermenting silicate bacteria, azotobacter chroococcum, actinomycetes, saccharomyces cerevisiae and rhodopseudomonas sphaeroides, wherein the silicate bacteria, the azotobacter chroococcum, the actinomycetes, the saccharomyces cerevisiae and the rhodopseudomonas sphaeroides are mixed together in a weight fraction of 1:1:1:1:1. The microbial compound fertilizer acting on a big field can increase the yield of crops by 20 to 30 percent, and simultaneously can obviously increase the percentage of fertile fruits, reduce fruit dropping and overgrow the fruits; besides, the maturation stage is shortened by 5 to 7 days, the yield-increasing effect is obvious, and simultaneously, the microbial compound fertilizer can obviously improve the appearance, the mouthfeel, the color and luster and the like of products, improve the quality by 1 to 2 grades, and prolong the product freshness date.
