Embodiment

[0033] The original strains of Streptomyces avermitilis, Paecilomyces lilacinus and Verticillium chlamydoides were used on the fungal culture medium plate, and the original strains of Bacillus sphaericus were activated and cultivated in the laboratory for 1 day on the slope of the bacterial culture medium. Each strain was cultured in shake flasks for 2 days in the liquid medium identical to the respective activation medium components, and then the strains cultured by the shake flasks were cultured in a 500L fermenter with the same 10% concentration of mashed potatoes and The culture medium of 3% soybean meal powder was cultivated for 27 hours, and finally the cultured Streptomyces avermitilis, Paecilomyces lilacinus, Verticillium chlamydoides, Bacillus sphaericus and sterilized glycerin were mixed with 30%, 15 %, 25%, 10% and 20% are mixed together.

experiment example

[0034] Experimental example: In mid-March 2012, the experimental work of the microbial preparation for inhibiting root-knot nematode was carried out in Daping Township, Tongcheng County, Hubei Province and Anjiang Town, Huaihua City, Hunan Province respectively. The demonstration area is 130 mu, and the soil conditions, water and fertilizer and various management levels are consistent during the demonstration process. The demonstration fields are all greenhouses where celery has been planted for many years, and the root-knot nematode disease is serious. Every year, the land is carefully cultivated, carefully managed and maintained, and a large amount of money is invested in the purchase of chemical fertilizers and pesticides to increase land fertility and eliminate pests and diseases. Area reduction of more than 40%. After using this invention this year, amazing changes have taken place in the vegetable field: the root-knot nematodes that were relatively useless in the invent...

Abstract

The invention belongs to the field of biological prevention and control on crop insect damage and provides a microbial preparation for inhibiting root-knot nematode. The preparation is formed by mixing bacterial liquids of streptomyces avermitilis, paecilomyces lilacinus, verticillium chlamydosporium and Bacillus sphaericus and glycerol. The invention also provides a production method and an application effect of the microbial preparation for inhibiting the root-knot nematode. The microbial preparation comprises viable bacteria of which the number is greater than 2,500 millions per milliliter, wherein the viable bacteria comprise the streptomyces avermitilis, the paecilomyces lilacinus, the verticillium chlamydosporium and the Bacillus sphaericus. After the microbial preparation is prepared into soil, eggs of the root-knot nematode are killed by metabolites generated in the continuous growth and reproduction activity process of the viable bacteria, so that a granular structure of the soil is improved, the utilization rate of a fertilizer is improved and an effect of increasing both production and income is achieved.

Description

technical field [0001] The invention belongs to the field of biological control of crop pests, and relates to a microbial preparation for inhibiting root-knot nematodes, a preparation method and application thereof. Background technique [0002] Since root-knot nematode disease was first reported in southern my country in 1932, root-knot nematode disease has occurred in more than ten provinces and autonomous regions across the country. In recent years, vegetables in my country's protected areas have developed rapidly, and the same vegetable crops have been planted in greenhouses year after year, resulting in the increasing severity of root-knot nematode diseases in many old greenhouses, which has caused a substantial reduction in vegetable production and brought huge economic losses to vegetable farmers. Generally, 20%-25% of the economic loss is caused every year, and the serious loss is 50%-60%, or even production is lost. Therefore, the management of root-knot nematode d...
