Embodiment 1

[0036] 1. the preparation method of slow-release compound medicinal fertilizer, comprises the following steps:

[0037] (1) Preparation of culture medium: Weigh materials according to the following weights: bran 3.6kg, corn flour 1.2kg, glucose 0.20kg, water 5.0kg, ammonium dihydrogen phosphate 0.05kg, adjust the pH value to 6.0, and steam at 115°C Sterilize for 20 minutes to obtain;

[0038] (2) Preparation of fermentation agent: inoculate Bacillus subtilis and Penicillium fungus into the above-prepared culture medium respectively, expand and cultivate Bacillus subtilis for 4 days under aerobic conditions at 25-30°C, and Penicillium fungus The mold was cultured for 5 days, and the culture was dried at 39°C under normal pressure and then pulverized evenly. The effective number of viable bacteria in the obtained bacterial preparation was more than 100 million / g, and the rate of miscellaneous bacteria was lower than 30%;

[0039] (3) Weigh 40kg of molasses alcohol waste liquid,...

Embodiment 2

[0047] 1. the preparation method of slow-release compound medicinal fertilizer, comprises the following steps:

[0048] (1) Weigh 50kg of molasses alcohol waste liquid, 50kg of animal manure, 30kg of bagasse, and 30kg of straw;

[0049] (2) Put the molasses alcohol waste liquid, animal manure, bagasse, and rice straw in the fermentation tank, add 5% of the total weight of the material fermenting agent (the fermenting agent is a commodity purchased on the market, made of Trichoderma longifolia, fake urin Trichosaccharomyces, Schizosaccharomyces and Candida tropicalis are produced by culturing, the effective number of viable bacteria in the agent is more than 50 million / g, and the rate of miscellaneous bacteria is less than 30%), mixed evenly, at 40-70℃, Fermented under aerobic conditions for 7 days, dried at 70°C, and powdered to obtain bio-fertilizer;

[0050] (3) Weigh 30kg of tea meal and 2kg of chlorantraniliprole, crush the materials separately, pass through a 60-mesh sie...

Embodiment 3

[0056] 1. the preparation method of slow-release compound medicinal fertilizer, comprises the following steps:

[0057] (1) Preparation of medium: same as Example 1

[0058] (2) Preparation of fermentation agent: Inoculate Aspergillus niger and Geotrichum candidum into the above-mentioned prepared culture medium respectively. Under aerobic conditions at 25-30°C, expand and cultivate Aspergillus niger for 4 days, and Geotrichum candidum for 2 days. After drying in the sun, the compound is crushed evenly, the effective number of viable bacteria of the obtained bacterial agent is more than 100 million / g, and the rate of miscellaneous bacteria is lower than 30%;

[0059] (3) Weigh 30kg of molasses alcohol waste liquid, 30kg of animal manure, 20kg of bagasse, and 20kg of straw;

[0060] (4) Put the molasses alcohol waste liquid, animal manure, bagasse, and wheat straw into the fermentation tank, add 0.2% of the total material weight of the fermentation agent (Aspergillus niger: Ge...

Abstract

The invention discloses a controlled-release compound pesticide fertilizer. The controlled-release compound pesticide fertilizer is characterized by being prepared from the following raw materials in parts by weight: 60-70 parts of biological fertilizer, 20-30 parts of pesticide fertilizer, 2-5 parts of calcium phosphate, 2-5 parts of magnesium sulfate, 0.5-1 part of zinc sulfate, 0.5-1 part of borax and 0.5-1 part of compound sodium nitrophenolate; the biological fertilizer is formed from the following materials in parts by weight: 30-50 parts of sugarcane molasses alcohol wastewater, 30-50 parts of animal waste, 20-30 parts of bagasse, 20-30 parts of straws and also a fermenting microbial agent accounting for 0.2-5% of the total weight of the materials through microbial fermentation; the pesticide fertilizer is formed by crushing the following materials in parts by weight: 20-30 parts of tea seed cake and 0.5-2 parts of chlorantraniliprole, mixing the materials evenly, pelleting, and coating the granular pesticide fertilizer by using a coating material accounting for 2-10% of the total weight of the materials. The controlled-release compound pesticide fertilizer is scientific in formula, and capable of providing comprehensive nutrition for crops, promoting the growth of the crops and improving the quality of soil, and also has the effects of insect prevention and insect killing; the active ingredients are slowly released in the growth process of the crops, and therefore, the utilization rate of the fertilizer and the pesticide can be increased and the pollution on the environment caused by the pesticide and the fertilizer can be reduced.

Description

technical field [0001] The invention relates to an agricultural compound fertilizer, in particular to a slow-release compound medicinal fertilizer. Background technique [0002] There are direct or indirect relationships between fertilizers, pesticides, soil and crops. With the development of agricultural production and the continuous improvement of the level of science and technology, the mixed use of fertilizers and pesticides, which makes the two operation steps in the field into one, has become an important development direction in the agricultural field. The research on medicinal fertilizers in our country began in the 1980s, and there have been many studies at present, but there are still relatively few studies on slow-release medicinal fertilizers. The biggest feature of slow-release medicinal fertilizers is that the release of fertilizers and pesticides is synchronized with the absorption of crop growth needs, so that one-time fertilization can meet the needs of cro...
