Problems solved by technology

At present, cotton long is widely used in soil disinfection of serious soil-borne diseases of economic crops, which can effectively kill fusarium wilt, root rot, rhizoctonia solani, sclerotinia, anthracnose, gray mold, morning and evening blight, yellow Wilt wilt, root-knot nematode and common weed seeds and other harmful organisms (but have no inhibitory effect on most bacteria in the environment), soil-borne diseases are serious in strawberry, cotton, watermelon, banana, cucumber, tomato and other fruit and vegetable crops The planting area where it occurs is widely used, but there are no literature and patent reports on killing plant pathogenic bacteria in the harmless composting of vegetable residues

Embodiment 1

[0019] Embodiment 1: The growth inhibitory action test of cotton long to common phytopathogenic fungi hyphae and spores

[0020] Inoculate 6 kinds of pathogenic fungi: Rhizoctonia solani, Pythium solani, Fusarium wilt of pepper, Phytophthora capsici, Anthracnose capsicum, Sclerotinia sclerotiorum into PDA plate culture medium respectively, culture at 28-30°C for 5 days and use The mycelium block with a diameter of 5mm is obtained by punching a hole for subsequent use.

[0021] (1) Metron's inhibition test on mycelia growth of common plant pathogenic fungi

[0022] Inoculate the mycelia blocks of 6 kinds of pathogenic fungi in the middle of the PDA plate culture medium respectively (at this moment, the gas space volume in the petri dish is 63.7cm 3 ), add a certain amount of cotton wool to the center of the petri dish cover, so that the concentration of cotton wool in the gas space in the petri dish is 0, 0.2, 0.4, 0.6, 1, 2, 6, 10 mg / L and then add cotton wool Sterile water ...

Embodiment 2

[0034] Example 2 The killing effect test of Mironon in the composting of vegetable residues to Sclerotinia sclerotiorum of pepper

[0035] Time: September 2014;

[0036] Location: Liuhe Animal Science Base, Jiangsu Academy of Agricultural Sciences;

[0037] Use a pulverizer to crush the pepper plants harvested from the pepper fruits to 5-8 cm as compost materials. When the ambient temperature is above 15°C, measure the carbon-nitrogen ratio of the compost materials according to the standard NY884-2012 of the Ministry of Agriculture, and the result is 21. Determine according to the measurement results Add 0.5% (w / w) bran in the vegetable residue, adjust the carbon-to-nitrogen ratio to be 28, measure the water content of the material to be 67%, then evenly add cotton wool, the dosage form is 98% wettable powder, and the addition is 0.15 kg per cubic meter, stir quickly and evenly, and then stack the materials into 5 circular piles with a bottom diameter of 1.5 meters and a heig...

Embodiment 3

[0042] Embodiment 3 Vegetable residues are sterilized and decomposed

[0043] Use a pulverizer to grind the pepper plants harvested from the pepper fruits to 5-8 cm as compost materials. When the ambient temperature is above 15°C, measure the carbon-nitrogen ratio of the compost materials according to the standard NY884-2012 of the Ministry of Agriculture, and adjust the vegetable residues according to the measurement results. The carbon-to-nitrogen ratio of the body is 28, and the water content of the measured material is 67%, and then evenly add cotton wool, the dosage form is 98% wettable powder, the addition amount is 0.15kg per cubic meter, stir quickly and evenly, and then pile the material into the bottom A circular pile with a diameter of 1.5 meters and a height of 1 meter is covered with a plastic film with a thickness of 0.05 cm. The bottom of the film is pressed into the bottom of the pile close to the ground to ensure that the surroundings of the pile are well seale...

Abstract

The invention discloses a method for efficiently killing pathogenic bacteria in vegetable wrack compost. The method comprises the following steps of: carrying out compost fermentation on vegetable wrack, crushing the vegetable wrack with water content of 80-85%, thus obtaining compost material; regulating carbon nitrogen ratio of the compost material to 25-30, evenly scattering the compost material into dazomet according to addition quantity of 0.15kg / m<3> and quickly mixing well, then, covering the compost material with a plastic film, carrying out sealed fermentation for 10-12 days, lifting up the plastic film and turning, and then, laying aside for 1-2 days. In the method, a chemical fumigant, namely dazomet, is used for processing the vegetable wrack post; in comparison with the existing pathogenic bacteria killing method by steam heating, adding chemical pesticide, and so on, the method provided by the invention is efficient, economic, safe, simple and easy to carry out, thus, a new thought for agricultural residue resource recycling, environment protection and diseases and suppression of insect pests spreading is provided.

Description

technical field [0001] The invention relates to the field of comprehensive utilization of agricultural waste, in particular to a method for efficiently killing pathogenic bacteria in vegetable residue compost. Background technique [0002] Over the years, my country's vegetable production has continued to develop steadily and has become the world's largest vegetable producer and consumer. The vegetable planting area increased from 95 million mu in 1990 to 295 million mu in 2011, and the output increased from 195 million tons in 1990. Increased to 679 million tons in 2011, and in recent years, the area has grown by about 3% every year. The vegetable industry has become an indispensable pillar industry for the national economy and people's livelihood. However, it must be noted that while vegetable planting and processing meet people's living needs and drive economic development, they also produce a considerable amount of vegetable residues, which also poses a huge pressure on r...
