Problems solved by technology

[0002] Soil is the carrier of plant growth and can provide most of the essential elements in the metabolic process of plant life. However, in recent years, due to people's blind pursuit of high yield, a large amount of inorganic fertilizers have been applied to the soil, resulting in compaction and aging of the soil. Part of the fertilizer is consolidated and cannot be used by plants, resulting in waste of resources
At the same time, chemical fertilizers will also produce some toxic substances in the production process, which will seriously pollute the environment, so it is very necessary to use a new type of fertilizer to replace the use of chemical fertilizers in whole or in part.

Embodiment 1

[0015] The compound biological fertilizer is calculated by weight percentage: 40% of organic matter, 15% of corn stalks, 14% of the fermentation product of biological bacteria fermentation liquid, and finally adding 31% of inorganic nutrients, which is the compound biological fertilizer.

[0016] Preparation: Dry 15% corn stalks in the sun, crush them into powder and place them in the fermentation tank, add appropriate amount of water, hold them into a ball with your hands, no water drops dripping, it is better to disperse when touched, then add 40% organic matter, 1% yeast fermentation broth, 2% Rhodopseudomonas palustris fermentation broth for mixed fermentation, fermented at 30-40°C for 3-4 days, then added 3% Bacillus megaterium, 5% Azotobacter torus and 3% Silicate bacteria are fermented at 25-30° C. for one more day, and finally 8% nitrogen nutrients, 12% phosphorus nutrients, and 11% potassium nutrients are added to form a compound biological fertilizer.

Embodiment 2

[0027] The difference from Example 1 is:

[0028] Compound biological fertilizer, by weight percentage, humic acid 20%, bean cake 10%, mixed plant straw 25%, 15% fermented biological bacteria liquid that is 2% yeast, 4% Rhodopseudomonas palustris, 3% phosphate solubilizing bacteria , 3% of silicate bacteria, 3% of nitrogen-fixing bacteria and 30% of the fermentation product of inorganic nutrients, that is, compound biological fertilizer. Wherein, the mixed plant straw is a mixture of wheat straw, rice straw, soybean straw and corn straw of the same weight.

[0029] Preparation: According to the weight percentage, dry 25% of the mixed plant stalks in the sun, crush them into powder, put them in the fermentation tank, add an appropriate amount of water, and hold them into a ball with your hands. There is no water drop, and it is better to disperse as soon as you touch it. Add 20% humic acid, 10% bean cake, 2% yeast, 4% Rhodopseudomonas palustris for fermentation, ferment at 30-...

Abstract

The invention relates to an agricultural compound biofertilizer, in particular to a compound biofertilizer capable of improving the physical and chemical properties of soil and improving the yield and quality of agricultural products and a preparation method thereof. The fertilizer contains the following materials in percentage by weight: 30-40% of organic substance, 15-25% of plant straw, 14-15% of mixed biological fermentation bacterium liquid and 30-31% of inorganic nutrient, wherein the biological bacteria used in the invention comprise Rhodopseudomonas palustris, microzyme, azotobacter, phosphorus-solubilizing Bacillus megaterium and silicate bacteria; the organic substance components are humic acid, worm excretion and bean cakes; and the inorganic nutrient comprises N, P and K nutrient. The compound biofertilizer can be applied as basal fertilizer or additional fertilizer, and is applicable to all crops. By using the compound biofertilizer, the yield increase amplitude can be 8-10%.
