Composite water-retention fertilizer and its preparation method

Abstract

The invention discloses a composite traditional Chinese medicinal water-retention fertilizer and its preparation method, wherein the composite organic fertilizer comprises the following components: by weight, 1-4 parts of soluble chitosan, 4-8 parts of fulvic acid, 5-7 parts of corn flour and the like. The components are used in synergism, thus satisfying nutrient supply required by health growth of crops, effectively killing soil insects on crops and raising use efficiency of soil moisture. Meanwhile, the composite water-retention fertilizer is safe to human and animals and causes no environmental pollution.

Description

technical field [0001] The invention relates to a composite water-retaining fertilizer and a preparation method thereof. Background technique [0002] At present, there are generally three kinds of agricultural fertilizers in the Chinese market: one is chemical raw material fertilizer, one is organic fertilizer, and the other is chemical raw material and organic fertilizer mixed fertilizer; the disadvantage of chemical raw material: long-term use will cause land soil compaction, Affect the growth of crops, resulting in a gradual reduction in production; the disadvantages of organic fertilizers are: the nutrients required by plants are insufficient to meet the needs of crop production; they affect crop yields; the disadvantages of mixed fertilizers: the organic matter and total nutrients in the fertilizer formula are contradictory, so High and low, if the organic matter content is too high, it is difficult to produce granules. In addition, the total area of ​​arid and semi-a...

[0002] At present, there are generally three kinds of agricultural fertilizers in the Chinese market: one is chemical raw material fertilizer, one is organic fertilizer, and the other is chemical raw material and organic fertilizer mixed fertilizer; the disadvantage of chemical raw material: long-term use will cause land soil compaction, Affect the growth of crops, resulting in a gradual reduction in production; the disadvantages of organic fertilizers are: the nutrients required by plants are insufficient to meet the needs of crop production; they affect crop yields; the disadvantages of mixed fertilizers: the organic matter and total nutrients in the fertilizer formula are contradictory, so High and low, if the organic matter content is too high, it is difficult to produce granules

At present, the prevention and control of crop pests mostly depends on chemical pesticides. However, due to the relatively long residual period of chemical pesticides, it not only pollutes the soil environment, but also affects the quality of agricultural products. It is not suitable for the production of pollution-free agricultural products, especially agricultural products for export.
