CN122010614ACN 122010614 ACN122010614 ACN 122010614ACN-122010614-A

Abstract

The invention discloses a biological fertilizer synergist and application thereof, and the biological fertilizer synergist comprises 30-85% of the synergist and 15-30% of the auxiliary agent in percentage by weight. The biological fertilizer synergist is uniformly sprayed on the surface of the granular fertilizer, and the granular biological fertilizer is obtained after low-temperature drying. The biological fertilizer synergist can adopt inorganic fertilizer, organic fertilizer or organic-inorganic fertilizer as granular fertilizer, and can be suitable for almost all granular fertilizers (except fertilizers with a function of killing microorganisms or antagonizing components in the biological fertilizer synergist) on the market at present. The production process is simple, the cost is low, the added value of the product can be effectively improved, the novel fertilizer belongs to the production process of the novel fertilizer, and the novel fertilizer has great market popularization value.

Description

Biological fertilizer synergist and application thereof Technical Field The invention belongs to the technical field of microbial fertilizers, and particularly relates to a biological fertilizer synergist and application thereof. Background The traditional organic fertilizer mainly has an improvement effect on soil, has no obvious synergistic effect on crops, can show an effect after long-term use, is not favored by growers when the agricultural planting period is obviously shortened, and gradually shows a plurality of defects when the application amount of the chemical fertilizer is increased, such as eutrophication of rivers and lakes caused by abuse of the chemical fertilizer, damage of ecological systems, excessively high nitrate content in underground water threatens human health, and causes soil hardening, reduction of organic matter content, imbalance of microbial communities and resistance to sustainable development of agriculture after long-term application of the chemical fertilizer. The development direction of the current fertilizer is integration of multiple fertility, research of a novel fertilizer and quality improvement and synergy of a traditional fertilizer, aiming at the defects of the current fertilizer, the fertilizer synergist which has the advantages of prolonging the fertilizer efficiency, improving the fertilizer utilization rate, promoting the crop growth and increasing the stress resistance of crops is adopted to be compatible with the fertilizer, the additional value of the traditional fertilizer can be improved, the integration of multiple fertility is carried out, the thinking of sustainable development is met, and the novel fertilizer product which is green, environment-friendly and efficient is obtained. Meanwhile, the preparation method of the patent is to uniformly mix the compound microbial agent with an auxiliary agent prepared by any one or more of aminobutyric acid, polyglutamic acid, molasses and chitosan, then spray-coating the mixture on the surface of a granular fertilizer, and drying the mixture at a low temperature to obtain the compound microbial fertilizer with high nutrient content and the preparation method thereof (application number: 201410851245.5), the granular biological fertilizer prepared by the method can keep the effective viable count of the product to the maximum extent, the moisture content of the obtained finished product is lower, the effective viable count is in an ascending trend after 90 days of shelf life observation, and the appearance is good after 180 days of storage, so that the fertilizer has no phenomena of hardening, deliquescence, moisture absorption and bacteria growth.
