Problems solved by technology

However, the current application of lumbrokinase in agricultural production is very limited. On the one hand, due to technical reasons, it is difficult for farmers to grasp the application method and dosage of lumbrokinase. not obvious
Using modern industrial technology, compound fertilizer and lumbrokinase are granulated together in a certain proportion, and one-time application in the farmland can effectively solve the above problems. At present, there are no related technologies and patent reports on stable lumbrokinase fertilizers.

Abstract

The invention discloses a stable lumbrukinase granulated fertilizer. The fertilizer comprises the following components: basic fertilizer, lumbrukinases and long-acting stabilizer, wherein the content of the lumbrukinase is between 0.2 and 0.6 per mill, and the content of the long-acting stabilizer is between 0.20 and 0.60 percent. The preparation method of the fertilizer comprises the following steps of A, amplifying the lumbrukinase and the long-acting stabilizer; B, measuring the components and uniformly stirring; C, extruding; D, crushing and classifying; E, polishing and trimming; and F, and screening for the second time, and measuring and packaging. The product and the preparation method provided by the invention have the characteristics of green environment friendliness, can be used for effectively improving the soil aggregation structure, eliminating soil hardening and reinforcing the soil infiltration capability, and can be used for promoting growth and development of beneficial microorganisms in the soil, improving the utilization of fertilizer, and finally promoting root growth of crops, so that the effect of remarkably increasing production can be achieved.

Description

technical field [0001] The invention relates to the technical field of agricultural compound fertilizers, in particular to a long-acting compound fertilizer containing lumbrokinase. Background technique [0002] The decisive role of chemical fertilizers in crop production has been recognized, but the fertilizer utilization rate is low and waste is very serious. There are many reasons for the low utilization rate of chemical fertilizers. On the one hand, the release rate of fertilizer nutrients is not synchronized with the growth period of crops is one of the important reasons; The soil microbiota is damaged to varying degrees and crop diseases occur frequently, resulting in weakened crop nutrient absorption capacity and reduced fertilizer utilization efficiency. At present, fertilizers added with natural organic raw materials are widely used, and are gradually achieving the purpose of improving fertilizer efficiency and reducing the amount of chemical fertilizers.
