Compound water-retention fertilizer and preparation method thereof

Abstract

The invention discloses a compound moisture-retention fertilizer and a preparation method thereof. The compound organic fertilizer is prepared from the following components in parts by weight: 1-4 parts of soluble chitosan, 4-8 parts of fulvic acid, 5-7 parts of corn flour, 6-8 parts of honeysuckle flower powder, 4-6 parts of bean pulp powder, 8-13 parts of rape seed cake, 5-8 parts of furfural residue, 6-10kg of calcium ammonium nitrate, 20-25 parts of potassium dihydrogen phosphate, 8.6-10.5 parts of urea, 1-4 parts of corn starch-acrylic acid copolymer, 4-7 parts of rare-earth element, 1-3 parts of dexon, 2-4 parts of chlorothalonil and 2-4 parts of adhesive. Under the synergistic actions of the components, the compound moisture-retention fertilizer can satisfy the nutrient supply required by crop healthy growth, effectively kill soil insects of the crops and enhance the utilization efficiency of soil water; and meanwhile, the invention is safety for people and livestock, and does not produce any 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.
