Problems solved by technology

For bottom topdressing, if there is no rain during topdressing, a large amount of chemical fertilizers will evaporate, and if there is too much rain, the chemical fertilizers will be lost with water, the utilization rate is extremely low, and a lot of labor is wasted; with one-time input, deep fertilization is required, and it is easy to burn the roots and seeds

Embodiment l

[0026] 79kg of organic fertilizer with 45% organic content, 20kg of slow and controlled release inorganic fertilizer resin coated particles mixed with 46% urea, 57% diammonium phosphate and 60% potassium chloride in a ratio of 5:3:2, slow control The release inorganic fertilizer is then coated with 1kg clothianidin, and the organic fertilizer is uniformly mixed with the slow and controlled release inorganic fertilizer coated with the pesticide to obtain the fertilizer of the present invention.

Embodiment 2

[0028] Mix 64.5kg of organic fertilizer with 50% organic content, 35kg of slow and controlled release inorganic fertilizer resin coated particles mixed with 46% urea, 55% monoammonium phosphate and 60% potassium chloride in a ratio of 7:3:4. The controlled-release inorganic fertilizer is coated with 0.5kg clothianidin, and the organic fertilizer is uniformly mixed with the controlled-release inorganic fertilizer coated with pesticide to obtain the fertilizer of the present invention.

Embodiment 3

[0030] 49kg of organic fertilizer with 60% organic content, 50kg of slow and controlled release inorganic fertilizer resin coated particles mixed with 46% urea, 55% monoammonium phosphate and 60% potassium chloride in a ratio of 7:3:4, slow control The fertilizer of the present invention is obtained by coating 1 kg of inorganic fertilizers with a mixture of insecticide and clothianidin in a ratio of 9:1, and uniformly mixing organic fertilizers and slow and controlled-release inorganic fertilizers coated with pesticides.

Abstract

The invention discloses a mixed slow controlled-release fertilizer of organic and inorganic pesticides. The mixed slow controlled-release fertilizer comprises the following components by weight percent: 0.01-1% of pesticides, 20-50% of slow controlled-release inorganic chemical fertilizer, and the balance of organic fertilizer. The slow controlled-release inorganic chemical fertilizer is evenly mixed with the organic fertilizer according to the ratio after being coated by a pesticide, so as to obtain the fertilizer disclosed by the invention. By adopting the mixed slow controlled-release fertilizer, soil can be effectively prevented from hardening and degenerating, the mixed slow controlled-release fertilizer is high in fertilizer utilization rate, and long in lasting period, balanced supply of nutrients of the crops from the seedling stage to the mature period can be ensured, meanwhile, an insect pest can be prevented and controlled, the yield of the crop is further increased, and the cost is reduced.

Description

Technical field [0001] The invention relates to a fertilizer for agriculture, more specifically a mixed slow and controlled release fertilizer of organic and inorganic pesticides. Background technique [0002] my country is a big agricultural country, and agricultural development is the guarantee of national economic and social development. Chemical fertilizers play a huge role in agricultural development, such as increasing crop yields, improving soil fertility, and compensating for insufficient arable land. However, the utilization rate of chemical fertilizers is very low. The utilization rate of nitrogen fertilizer is 25%-40%, phosphate fertilizer is only about 20%, and potash fertilizer can reach more than 30%, and the lost chemical fertilizer will cause environmental pollution. Scientific fertilization, convenient fertilization, and improvement of fertilizer utilization have become issues of great concern to farmers today. [0003] At present, most of the fertilizer fertiliz...
