Embodiment 1

[0019] (1) Isolation and identification of strains

[0020] Isolation of Aspergillus niger, Trichoderma viride, and Bacillus licheniformis: These three bacteria were separated from garden waste and straw piles, and separated by streaking on a plate with garden waste as the only carbon source of the medium;

[0021] Pichia burtonii was purchased from Guangdong Institute of Microbiology.

[0022] Isolation of Bacillus subtilis: The bacterium was sampled from the rhizosphere soil of crops where bacterial wilt occurs, and was isolated by dilution plate method and antibacterial method.

[0023] Screening and isolation of Bacillus glialis and Bacillus pumilus: samples were taken from the rhizosphere soil of crops, and screening and isolation were carried out by the growth promotion contrast method and the dilution plate method.

[0024] Identification of Aspergillus niger, Trichoderma viridans, Bacillus licheniformis, Bacillus subtilis, Bacillus coli, and Bacillus pumilus: traditio...

Abstract

The invention discloses a microbial organic fertilizer for preventing bacterial wilt as well as a preparation method and an application thereof. The fertilizer is formed by mixing garden waste, animal excrement, decomposing inoculums and a microbial agent according to a given weight ratio, the number of active live bacteria in the fertilizer is 2*10<7> / g or more, the pH value is 7.3, the water content is 29.7 percent, the content of organic matters is 41.2 percent, the total nitrogen content is 1.28 percent, the total potassium content is 1.45 percent, and the total phosphorus content is 1.60 percent. The invention also provides a preparation method of the microbial organic fertilizer and an application. The problems in the prior art are solved, the microbial organic fertilizer for preventing the eggplant crop bacterial wilt and the preparation method thereof are provided, the problems in the traditional method that the effect is unstable, the prevention effect is poor and the like are overcome, the advantages of the ecological control and prevention and microbial prevention are combined, and the recycling of waste can be promoted.

Description

technical field [0001] The invention relates to the technical field of biological fertilizers, in particular to a microbial organic fertilizer for preventing and treating bacterial wilt of solanaceous crops. Background technique [0002] Bacteria wilt is a common soil-borne disease of Solanaceae crops in southern China. It is caused by R. solanacearum. It is more serious in high-temperature and high-humidity areas and continuous cropping plots. Traditional soil additive control, agricultural control, The effect of chemical control is not obvious, and it is easy to bring many negative effects. Soil additives not only kill pathogenic bacteria, but also seriously damage indigenous microorganisms; agricultural measures are heavy in workload, and the intensive use of land is not high; chemical control methods such as spraying pesticides are not only ineffective, but also lead to pathogenic bacteria. disease resistance. Therefore, it is imperative to study a new method of preven...
