Method for preparing pine-cypress substrate bacterial fertilizer

Abstract

The invention discloses a method for preparing a pine-cypress substrate bacterial fertilizer. The method comprises the steps of: implementing fermenting preparation indoors at the room temperature of 5-30 DEG C; airing and grinding cypress seed husks and sesame oil residues; passing the ground cypress seed husks and the sesame oil residues through a sieve net with fineness being 800 microns; evenly mixing and stirring the cypress seed husks and the sesame oil residues by a weight ratio of 2.5:1 to form a culturing medium; adding actinomycetes and trichodermin into the culturing medium, wherein the contents of the actinomycetes and the trichodermin are respectively 0.2 billion per gram and the weight ratio of the culturingmedium to the actinomycetes to the trichodermin is 40:2:1; evenly mixing and stirring the actinomycetes, the trichodermin and the culturing medium; adding clean water and evenly stirring to obtain mixed materials, wherein the water content is 70-75%; piling up the mixed materials; covering the mixed material pile with a thin plastic film; covering the thin plastic film with a light-proof straw or hair felt and then implementing fermentation; turning the pile when a white mildew layer occurs on the surface of the culturing medium; turning the pile again when another white mildew layer occurs on the surface of the culturing medium; preparing a finished product until the culturing medium becomes black brown. The method is simple and easy to master, and the product has the advantages of evading soil pests, adsorbing heavy metal elements from soil, supplementing organic substances in the soil, improving the physical and chemical properties of the soil, improving the permeability of the soil, and the like.

Description

technical field [0001] The invention relates to a method for preparing organic fertilizer, in particular to a method for preparing bacterial fertilizer with pine and cypress as the main matrix. Background technique [0002] The utilization rate of inorganic fertilizers in my country is maintained at about 20%. With the accumulation of unusable fertilizers in the soil, the soil permeability becomes worse year by year, and acidic soil appears, which leads to soil degradation, which is not conducive to the growth of crops, and at the same time, the quality of agricultural products deteriorates. . In recent years, the root diseases of crops have shown a trend of increasing year by year. The frequent use of soil fungicides not only prevents harmful bacteria from harming crops, but also kills beneficial bacteria in the soil, destroys the balance of soil colonies, and prevents the growth of crop roots. The environment tends to deteriorate, and the ratio of input and output is out o...

[0002] The utilization rate of inorganic fertilizers in my country is maintained at about 20%. With the accumulation of unusable fertilizers in the soil, the soil permeability becomes worse year by year, and acidic soil appears, which leads to soil degradation, which is not conducive to the growth of crops, and at the same time, the quality of agricultural products deteriorates.

In recent years, the root diseases of crops have shown a trend of increasing year by year. The frequent use of soil fungicides not only prevents harmful bacteria from harming crops, but also kills beneficial bacteria in the soil, destroys the balance of soil colonies, and prevents the growth of crop roots. The environment tends to deteriorate, and the ratio of input and output is out of balance, resulting in low agricultural production efficiency

Due to the emphasis on the use of chemical fertilizers and neglect of the use of organic fertilizers in agricultural production, the organic matter in the soil is severely lacking, which is not conducive to the activities of microorganisms and primitive animals in the soil.

The lack of organic matter in the soil, soil fertility and buffering properties are poor, and it is difficult to fertilize the soil
