[0023] 1. Determination of effective nutrients of materials and determination of input amount

[0024] Sampling and determination of effective content and moisture content of nitrogen, phosphorus, potassium, magnesium, zinc and boron-related nutrients in raw materials required for the production of urea, monoammonium phosphate, ammonium sulfate, potassium chloride, magnesium sulfate, zinc sulfate and boric acid, etc. The organic matter and moisture content of the required humic acid powder and fermented materials (prepared by drying, pulverizing and sieving after mixing the fungus residue and livestock manure at high temperature) to determine the moisture content of the pentonite binder required for production . Adjust and determine the input amount of each material according to the measurement results.

[0041] Example 2 Fertilizer efficiency of special fertilizer for corn and rice

[0042] 7-10 days after rice seedlings are transplanted, apply 40Kg of corn and rice special fertilizer prepared in Example 1 per mu (NPK nutrient content≧30%, NPK ratio is 18-5-7), when corn seedlings are transplanted or corn When sowing, apply 40Kg (intercropping corn) special fertilizer for corn and rice prepared in Example 1 per acre, without adding other chemical fertilizers. The nutrient supply of rice vegetative growth period (seedling stage and tillering stage) and corn seedling stage and ear stage is mainly provided by the available nutrients in the outer layer of special fertilizer for rice and corn (accounting for 35% of the total fertilizer mass, NPK nutrient content ≧ 34%, NPK The ratio is 22-5-7) to ensure good growth at the seedling stage; when rice enters the reproductive stage (long ear stage and fruiting stage) and corn enters the flowering stage, its nutrient supply is provided b...

Abstract

The invention discloses an organic and inorganic fertilizer with quick-acting and controlled-release functions and a preparation method thereof, and relates to the fields of a chemical composition and a preparation method thereof. The preparation method comprises the following steps: preparing master batch fertilizer in a disc or tumbling granulation manner, spraying xanthan gum and sulphur suspension liquid on the surface of the master batch fertilizer, and drying so as to form a layer of membrane on the surface of the master batch fertilizer; then preparing fertilizer slurry by using raw materials of the outer fertilizer, spraying the fertilizer slurry to the surface of the master batch fertilizer, spraying alkanamine acetate anti-blocking agent for the last time, carrying out air drying, cooling and bagging, thus obtaining the organic and inorganic fertilizer with the quick-acting and controlled-release functions. The organic and inorganic fertilizer with the quick-acting and controlled-release functions disclosed by the invention has long residual action of common organic and inorganic fertilizers and quick-acting property of common inorganic fertilizers; medium trace element nutrients and macroelements in the organic and inorganic fertilizer are synchronously released, so that the quick-acting and controlled-release integrated high-efficiency fertilization effect is achieved.

Description

technical field [0001] The invention relates to the field of chemical compositions and preparation methods thereof, in particular to an organic and inorganic fertilizer with quick-acting and slow-release effects and a preparation method thereof. Background technique [0002] In recent years, due to the transfer of rural labor force to industry and sideline industries, the amount of farm manure has dropped sharply, and the fertilization method mainly dominated by chemical fertilizers has gradually decreased. use, low fertilizer utilization rate, a large amount of chemical fertilizer leaching or physical and chemical fixation, not only causes the production cost to rise continuously, the production and planting benefit declines; but also brings about soil nutrient imbalance, soil physical degradation, water eutrophication and farmland ecological security Many problems have already caused harm to people's lives. Therefore, changing the fertilizer mode, improving fertilizer util...
