Problems solved by technology

[0006] At present, in the prevention and control of watermelon wilt, melon farmers still generally use pesticides. Although some achievements have been made in the prevention and control of watermelon People's health awareness is constantly improving, and there is more and more demand for organic melons and fruits. The strong efficacy of pesticides will cause some residues on melons and fruits while preventing and treating watermelon wilt, which is harmful to human health. On the other hand, the large-scale use of pesticides will not only produce drug resistance, but also bring serious burdens to the soil, causing soil environmental pollution, reducing soil fertility and increasing energy consumption.

Embodiment 1

[0033] Weigh 200 g of peeled and cut potatoes into 1400 mL of deionized water, boil at 100 ° C for 10 minutes, filter through three layers of gauze and set the volume to 1000 mL as a solvent; weigh 20 g of glucose, add it to the solvent and stir evenly, and pack in In the triangular flask, seal the package and sterilize it in a sterilizing pot at 121°C for 20 minutes. After cooling, it will be the prepared mold liquid culture medium;

[0034] The mold liquid culture is based on the inoculation ring of mold spores—Paecilomyces lilacinus—inoculated on the aseptic operation table, and the sealed package is placed in a shaker at 28°C for 4 days to obtain the mold—Paecilomyces lilacinus fermentation broth. Leave it for 5 days to make the liquid surface form a layer of spores for later use;

[0035] Weigh 100 g of soybean meal, 400 g of cornmeal, 200 g of bran, and 300 g of sawdust in a fermentation tank and stir evenly, then add 600 mL of deionized water to mix evenly, seal the packa...

Embodiment 2

[0038] Weigh 5 g of beef extract, 10 g of peptone, and 5 g of sodium chloride into a measuring cup, add deionized water to 1000 mL, stir evenly and adjust the pH to 7.0~7.2, then pack them into Erlenmeyer flasks, seal and store Sterilize in a sterilizing pot at 121°C for 20 minutes, and wait to cool to obtain a bacterial liquid culture medium;

[0039] Inoculate the sterilized and cooled liquid culture medium on the aseptic operating table with bacteria—Bacillus subtilis, seal the package and put it in a shaker at 36°C for 24 hours to obtain the bacteria—Bacillus subtilis fermentation broth;

[0040] Weigh 180 g of soybean meal, 300 g of cornmeal, 320 g of bran, and 200 g of sawdust in a fermentation tank and stir evenly, then add 600 mL of deionized water and mix evenly, seal the package and sterilize it in a sterilizing pot at 121°C for 40 minutes , the preparation medium of the acquired bacterial agent;

[0041] Inoculate 400 mL of bacteria—Bacillus subtilis fermentation b...

Embodiment 3

[0043] The method in Example 2 was adopted to prepare bacterial liquid culture medium. Bacterial liquid culture is based on the inoculation of bacteria-Pseudomonas fluorescens on the aseptic operation table, and the sealed package is placed in a shaker at 36°C for 24 hours to obtain the bacteria-Pseudomonas fluorescens fermentation broth;

[0044] Adopt the method in the embodiment 2 to prepare bacterial inoculum preparation culture medium. After cooling to room temperature, the preparation and cultivation of the bacterial agent is based on inoculating 400 mL of bacteria—Pseudomonas fluorescens fermentation broth on the aseptic operation table, stirring evenly, sealing the package and placing it in an incubator at 36°C for 24 hours. After successful fermentation Air-dried in a cool place and crushed into powder to obtain bacteria—Pseudomonas fluorescens biological agent T3.

Abstract

The invention discloses an agricultural microbial preparation, including a mold preparation or / and a bacterial preparation, wherein the mold preparation is inoculated with mold spores in a specially prepared liquid medium to obtain a mold fermentation liquid; Prepare the culture medium by obtaining the mold inoculum; mix the two in proportion, culture and ferment them, air-dry and crush them; the bacterial preparation also prepares the liquid medium first, and inoculates the bacteria to obtain the bacterial fermentation liquid; prepare and cultivate it with the bacterial inoculum The bases are mixed in proportion to be cultured and fermented, then air-dried and pulverized. The microbial preparation prepared by the present invention is green and safe, and after being applied in the soil, it plays an effective role in preventing and controlling soil root-knot nematode and watermelon wilt, enhances the growth and reproduction of beneficial bacteria in crop roots, inhibits the growth of harmful bacteria, and reduces pests and diseases Occurrence; Since pesticides are no longer applied, there is no problem of pesticide residues, and the requirements for the production of green and healthy agricultural products are realized; and it can make crops grow vigorously, increase production and income.

Description

technical field [0001] The invention relates to a microbial preparation, in particular to an agricultural microbial preparation, and also relates to the application of the microbial preparation in preventing and controlling melon root-knot nematode and watermelon wilt. Background technique [0002] Root-knot nematode infection of crops, especially for melons, fruits and vegetables cultivated in protected areas and off-season cultivation, is a very common phenomenon of pests and diseases. The color of vegetable leaves becomes pale or yellow, and the root system of the plant is damaged, resulting in a decrease in the ability of the plant to absorb nutrients, resulting in short plants, weak growth, rigid fruit, cessation of growth, and reduced yield. In severe cases, it will lead to crop death and failure. [0003] At present, with the improvement of human living standards and the increasing demand for green food, biopesticides are favored by growers of melons, fruits and veget...
