Embodiment Construction

[0018] The present invention will be further described below in conjunction with embodiment:

[0019] The steps of the preparation method of Abamectin medicinal dregs fertilizer of the present invention are as follows:

[0020] (1) 100~110 parts of cow dung, 5~10 parts of slag, 3~7 parts of corn stalks, 24~26 parts of ammonium bicarbonate, 15~17 parts of superphosphate, 7.2~7.8 parts of sulfuric acid Compost and ferment after potassium mixing, turn over once every 3 days, ferment for 30 to 33 days, and obtain cow dung with inorganic nutrients fixed by microorganisms after fermentation;

[0021] (2) pave the abamectin dregs with a thickness of 15 to 25 cm, then dry them in a ventilated environment at 22 to 28° C., and detect the water content of the abamectin dregs every 2 to 3 hours. The drying is completed when the water content of the abamectin dregs is 40% to 55%;

[0022] (3) After mixing 40-60 parts of cow dung with inorganic nutrients fixed by microorganisms, 30-45 par...

Abstract

The invention relates to a preparation method of abamectin dreg fertilizer; the method solves the problem that: the existing preparation method of the organic fertilizer affects the content of total nitrogen, total phosphorus and total potassium when reducing the content of inorganic nitrogen, phosphorus and potassium in the fertilizer. The preparation method is characterized in that: the preparation method comprises the following steps: (1) dairy manure, slag, maize straw, ammonium hydrogen carbonate and potassium sulphate are uniformly mixed, composted and fermented; after the fermentation is finished, the dairy manure, the inorganic nutrients of which are fixed by microorganisms is obtained; (2) the abamectin dreg is dried to have 40-55% of the water content; (3) the dairy manure, the inorganic nutrients of which are fixed by microorganisms, the abamectin dreg, humic acid and argil are uniformly mixed and are made into particles, thus obtaining the abamectin dreg fertilizer. The method not only can improve the content of total nitrogen, total phosphorus and total potassium in the organic fertilizer, but also can effectively reduce the content of inorganic nitrogen, phosphorus and potassium in the fertilizer simultaneously; therefore, the produced fertilizer has high content of the total nitrogen, the total phosphorus, the total potassium and organic matters.

Description

technical field [0001] The invention belongs to the field of organic fertilizers, in particular to a method for preparing organic fertilizers containing abamectin dregs. Background technique [0002] Organic fertilizers usually refer to a type of fertilizer made from natural organic matter decomposed or fermented by microorganisms. Human manure and livestock manure are the main raw materials of organic fertilizers. The preparation method of organic fertilizer is usually composting or retting after mixing feces with auxiliary materials such as straw, and using the microorganisms in the feces to ferment. The organic nitrogen, phosphorus, and potassium contained in organic fertilizers can be slowly released in the soil, providing nutrients for crops for a long time, which is beneficial to the growth of crops; at the same time, organic nitrogen, phosphorus, and potassium are macromolecular nutrients that have A certain amount of adsorption can improve the drought resistance, wa...
