Compound fertilizer with straw degradation function and preparing method thereof

Abstract

The invention discloses a compound fertilizer with a straw degradation function and a preparing method thereof. The preparing method of the compound fertilizer includes the following steps that a solid organic fertilizer is smashed, a solid microbial agent is added, the mixture is evenly mixed and then pelletized, and a fertilizer core is obtained; palm oil is sprayed to the surface of the fertilizer core, then an inorganic fertilizer, a pesticide and bentonite are added, the mixture is subjected to secondary pelletizing, drying is carried out, and the compound fertilizer is obtained. The compound fertilizer contains the microbial agent, and has the function of degrading straw, the degradation rate of the straw can be increased, the soil fertility is improved, and the compound fertilizer is suitable for being used as a base fertilizer.

Description

technical field [0001] The invention relates to the field of compound fertilizer preparation, in particular to a compound fertilizer with straw degradation function and a preparation method thereof. Background technique [0002] Chinese farmers have a long history of using crop stalks, but due to the low level of agricultural production and low output in the past, the amount of stalks was small. Except for a small amount of straw used for gaskets, feeding livestock, and some used for composting, most of the straw was used as fuel. Lost. With the development of agricultural production, since the 1980s, China's grain output has increased significantly, and the amount of straw has also increased. In addition, the promotion of firewood-saving and coal-saving technologies, the popularization of coal burning and the use of liquefied petroleum gas have resulted in a large amount of surplus straw in rural areas. . At the same time, due to the lack of convenient and effective utili...

Problems solved by technology

However, the direct return of straw to the field has the following disadvantages: the crushed straw is buried deep in the ground, it is difficult to rot, and the crops are planted, and the roots cannot penetrate into the soil, so they are easy to fall; the straw contains a large number of larval eggs, especially corn straw , if they are not completely removed during the process of returning to the field, they are buried in the ground and are easy to grow, which inadvertently increases the hidden dangers of diseases and insect pests
