Problems solved by technology

[0002] For agricultural production, fertilization and pesticide application are necessary links. In the first stage of crop growth, fertilization and pesticide application are often carried out many times due to different growth periods and insect pest periods, but not all fertilizers or pesticides are applied. Absorbed by crops, part of it is volatilized or lost due to the impact of the environment, resulting in a waste of resources and indirectly increasing production costs. Moreover, repeated fertilization and topdressing not only destroy the soil, pollute the environment, but also cause a large number of diseases and serious agricultural damage to crops. Disabled
[0003] In addition, in addition to some large-scale production farms in China that can carry out mechanized production, there are many others that are in semi-mechanized production. In these areas, crop production cannot fully meet the family's income, and many people are working outside. The management of crops in the field Some fertilizers and insect pest control can only be done at the time of sowing. This kind of crop management method that cannot meet the needs of adding fertilizers in various growth periods often leads to a significant drop in crop yields, and fertilization and pesticide application cannot be completed at one time. Greatly increased the workload and labor time of farmers, so the production of a controllable, slow-release fertilizer that integrates medicine and fertilizer has become inevitable

Abstract

The invention provides a coating agent chemical fertilizer which is prepared from the following materials in parts by weight: 1 part of a coating agent, 500-900 parts of chemical fertilizer particles and 20-60 parts of a film-forming agent. The invention further provides a preparation method of the coating agent chemical fertilizer. The preparation method comprises the steps of heating the coating agent to 150-200 DEG C, and spraying the coating agent to the chemical fertilizer particles; 2, uniformly mixing the sprayed chemical fertilizer particles with the film-forming agent; 3, cooling, screening and packaging. According to the method, the obtained coating agent chemical fertilizer can be released in a controlled slow manner and has the effect of preventing disease and pest damage.
