Problems solved by technology

[0003] At present, vegetable residues are usually discarded on the fields, roadsides, and drains to rot naturally, or are burned, which directly cause the following problems: (1) pollute the environment, and vegetable residues are decomposed through decomposition, producing a large amount of nitrogen, phosphorus, etc. Nutrient elements flow into rivers with surface runoff or directly infiltrate into the ground, becoming a source of agricultural non-point source pollution. In addition, rotting and burning also produce peculiar smells, which affect the beautification of the environment; Pathogens are cross-transmitted and infected between fields and crops; (3) waste of resources, vegetable residues contain a large amount of organic matter and minerals, and unreasonable treatment causes a large amount of nutrients to be lost

Embodiment 1

[0028] Source of raw materials: watermelon residues and wheat straw were collected from the experimental farm of the Chinese Academy of Agricultural Sciences, compost inoculant (EM bacterial agent, the number of viable bacteria ≥ 2×10 9 cfu / g) was purchased from Beijing Agricultural Production Material Company, and Eisenia chinensis was from Beijing Dahuan Farm.

[0029] Specific operation method:

[0030] Divided into 4 groups in the experimental farm of the Chinese Academy of Agricultural Sciences.

[0031] Group 1 (vegetable stump+wheat straw), the watermelon stump and wheat straw are pulverized to a length of about 1 cm respectively, watermelon stump: wheat straw=100: 0.8 is mixed in proportion by weight, naturally dehydrated to 60%, and naturally stacked for 42 days;

[0032] The 2nd group (vegetable stump+wheat straw+EM bacterial agent), watermelon stump and wheat straw are pulverized to about 1cm length respectively, watermelon stump: wheat straw=100: 0.8 mixes by weig...

Embodiment 2

[0042] Source of raw materials: Pepper residues and wheat straw were collected from the experimental farm of the Chinese Academy of Agricultural Sciences, compost inoculant (enzyme agent, the number of viable bacteria ≥ 2 × 10 9 cfu / g) was purchased from Beijing Agricultural Production Material Company, and Eisenia chinensis was from Beijing Dahuan Farm.

[0043] Specific operation method:

[0044] Divide into 3 groups and carry out in the experimental farm of Chinese Academy of Agricultural Sciences.

[0045] Group 1 (vegetable residues+wheat straw), pepper residues and wheat straw are crushed to a length of about 1 cm respectively, pepper residues: wheat straw=100: 1.0 is mixed evenly by weight, naturally dehydrated to 60%, and naturally stacked for 37 days ;

[0046] Group 2 (vegetable residues+wheat straw+enzyme bacteria), pepper residues and wheat straw are crushed to a length of about 1 cm respectively, mix uniformly by weight ratio pepper residues:wheat straw=100:1.0,...

Embodiment 3

[0052] Raw material source and specific operation method are basically the same as embodiment 1. The difference is that in this example, the transformation product of the present invention is fully mixed with the vegetable field soil at a ratio of 15:100 (wt / wt), put into a plastic bowl with a diameter of 20 cm, and the seeds of Zhongnong No. 16 cucumber are sown, and the growth and development of the cucumber seedlings are observed. condition and seedling index.

[0053] The experimental results are as follows:

[0054] As can be seen from Table 2, adding an appropriate amount of the transformation product of the present invention in the vegetable field soil has no adverse effect on the emergence rate of cucumber seeds, but promotes the growth and development of cucumber seedlings. The weight and seedling index were significantly better than those of the control. It shows that the product formed by the method of the present invention can be used as a high-quality organic fe...

Abstract

The present invention discloses microbe-earthworm inoculating vegetable stubble converting process in agricultural microbial conversion technology. The conversion process includes the following steps: 1. mixing vegetable stubble with wheat straw in certain weight ratio and C / N ratio of 25-30; 2. inoculating compost agent to ferment fast; and 3. post decaying while inoculating earthworm. The process can convert vegetable stubble into high quality organic fertilizer, and is favorable to reducing environmental pollution and utilizing resource effectively.

Description

technical field [0001] The invention belongs to the technical field of agricultural biomass conversion, and in particular relates to a step-by-step inoculation conversion method of vegetable residue microorganisms-earthworms. Background technique [0002] Since the 1980s, my country's vegetable industry has developed rapidly. According to statistics from the Ministry of Agriculture, the sown area and total output of vegetables (including melons) in China reached 19.928 million hectares and 640 million tons respectively in 2005, ranking first in the world. In the process of vegetable production, a large number of vegetable residues are produced, with an average of about 2000kg / 667m 2 , a total of more than 500 million tons nationwide. [0003] At present, vegetable residues are usually discarded on the fields, roadsides, and drains to rot naturally, or are burned, which directly cause the following problems: (1) pollute the environment, and vegetable residues are decomposed...
