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] Mix 79kg of organic fertilizer with an organic matter content of 45%, and 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. Release the inorganic chemical fertilizer and then coat 1kg clothianidin, and evenly mix the organic fertilizer and the slow and controlled release inorganic chemical 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 matter content, 35kg of slow-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 chemical fertilizer is then coated with 0.5 kg clothianidin, and the organic fertilizer is evenly mixed with the slow-controlled release inorganic chemical fertilizer coated with the pesticide to obtain the fertilizer of the present invention.

Embodiment 3

[0030] Mix 49kg of organic fertilizer with an organic matter content of 60%, and 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. Release inorganic chemical fertilizer and then coat 1 kg of pesticide mixed with monosultap and clothianidin at a ratio of 9:1, and evenly mix organic fertilizer with slow-controlled release inorganic fertilizer coated with pesticide to obtain the fertilizer of the present invention.

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 an agricultural fertilizer, in particular to a mixed organic and inorganic pesticide slow and controlled release fertilizer. Background technique [0002] my country is a large 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 lack of cultivated land. However, the utilization rate of chemical fertilizers is very low. The utilization rate of nitrogen fertilizer is 25%-40%, phosphorus fertilizer is only about 20%, and potassium fertilizer can reach more than 30%. Moreover, the lost chemical fertilizer will cause environmental pollution. Scientific fertilization, convenient fertilization, and improving the utilization rate of fertilizers have become the issues that farmers are very concerned about today. [0003] Most of th...
