Problems solved by technology

However, this kind of fertilizer can only release fertilizer according to its unique speed, but cannot fully meet the fertilizer demand law of crops, and the production cost is high, it is difficult to be accepted by the majority of farmers, and it is not conducive to large-scale promotion and application. Developing a more environmentally friendly and effective fertilizer , more economical and more practical loss control technology has become an urgent problem to be solved in agricultural production
[0003] In addition, China's current agricultural non-point source pollution problem is relatively serious.

Abstract

The invention relates to a loss-control fertilizer additive and a preparation method thereof, belonging to the technical field of agricultural fertilizers. The additive is prepared from the following raw materials in parts by weight: 30.00-49.50 parts of bentonite, 30.00-49.50 parts of smectite, 1.00-37.00 parts of polyacrylamide, 0-0.50 part of chitosan, 0-1.00 part of compound sodium nitrophenolate, 0-0.50 part of DMPP (dimethyl-phenyl-piperazinium) and 0-1.00 part of DA-6. The loss-control fertilizer additive has the advantages of high environment friendliness and favorable flocculability, can effectively prevent the nutrients in the fertilizer from loss, and does not influence the fertilizer absorption of crops, thereby achieving the goal of long lasting. Meanwhile, the loss-control fertilizer additive has the effect of improving the soil; after being applied into soil, the loss-control fertilizer additive can loosen the soil structure and improve the physical behaviors of the soil; and thus, the loss-control fertilizer additive has multiple functions and is very effective.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, and in particular relates to a loss-controlling fertilizer additive and a preparation method thereof. Background technique [0002] my country is a large agricultural country. According to statistics, the utilization rate of various fertilizers in my country is relatively low at present, among which nitrogen fertilizer is only 20%-50%, phosphorus fertilizer is 15%-25%, and potassium fertilizer is 30%-35%. In order to solve this problem, the current relatively common technology is to use controlled-release coating technology, using low-density polyethylene, sulfur and other substances as coating materials to achieve the purpose of slowing down the release rate of fertilizers and prolonging fertilizer efficiency, thereby reducing loss and saving energy. cost effect. However, this kind of fertilizer can only release fertilizer according to its unique speed, but cannot fully meet th...
