Problems solved by technology

[0006] Strawberry wilt is one of the main diseases that seriously affects the economic benefits and sustainable development of the strawberry industry. In the past, chemical fungicides were used to control strawberry wilt, but the large-scale use of chemical fungicides is likely to cause environmental pollution, ecological imbalance, drug residues, Food safety and other issues, so the use of low-cost, high-efficiency, environmentally friendly and drug-free biological methods to prevent and control strawberry wilt has attracted much attention

Embodiment 1

[0039] A special wilt-resistant bio-organic fertilizer for strawberries is prepared by a production method comprising the following steps:

[0040] (1) Pretreatment of compost raw materials

[0041] Mix fresh mink manure and corn stalks with a particle size of ≤1cm evenly at a mass ratio of 3-4.5:1-1.5, adjust the C / N between 25-30, adjust the moisture content to about 60%, and set aside.

[0042] (2) Preparation of compound microbial fermentation bacterium agent and biocontrol bacterium agent

[0043] Bacillus subtilis ABTNL-2, Bacillus thuringiensis ABTNL-4, Bacillus hescheri ZL-3, Bacillus megaterium, Bacillus coliformis and Bacillus licheniformis ABTNL-1 were separately fermented and produced in fermentation tanks , so that the bacterial concentration reached 10 8 ~10 9 CFU·ml -1 After fermentation, Bacillus subtilis ABTNL-2, Bacillus thuringiensis ABTNL-4, Helicobacter herstii ZL-3, Bacillus megaterium and Bacillus colloidus bacterial liquid are by volume percentage 1...

Embodiment 2

[0050] Step 1: Pretreatment of raw materials for composting

[0051] Mix fresh mink manure and corn stalks with a particle size of ≤1cm evenly at a mass ratio of 3-4.5:1-1.5, adjust the C / N between 25-30, adjust the moisture content to about 60%, and set aside.

[0052] Step 2: Preparation of compound microbial fermentation agent and biocontrol agent

[0053] Bacillus subtilis ABTNL-2, Bacillus thuringiensis ABTNL-4, Bacillus hescheri ZL-3, Bacillus megaterium, Bacillus coliformis and Bacillus licheniformis ABTNL-1 were separately fermented and produced in fermentation tanks , so that the bacterial concentration reached 10 8 ~10 9 CFU·ml -1 After fermentation, Bacillus subtilis ABTNL-2, Bacillus thuringiensis ABTNL-4, Helicobacter herstii ZL-3, Bacillus megaterium and Bacillus colloidus liquid are by volume percentage 1:1:1:0.5: 0.5 mixed as a composite microbial fermentation agent, Bacillus licheniformis ABTNL-1 fermented bacteria liquid as a biocontrol agent.

Abstract

The invention discloses a special anti-wilt biological organic fertilizer for strawberries prepared from mink, fox and raccoon dung and a preparation method thereof. The specific anti-wilt biologicalorganic fertilizer is prepared by taking the fresh mink, fox, raccoon dung and corn straw as stacking materials and inoculating a composite microbial fermentation agent consisting of bacillus subtilisABTNL-2, bacillus thuringiensis ABTNL-4, Herbaspirillum huttiense ZL-3, bacillus megaterium and bacillus mucilaginosus and bacillus licheniformis ABTNL-1 biocontrol agent through a one-step through composting fermentation process to obtain the biological organic fertilizer with anti-strawberry wilt function. According to the invention, a static aerobic composting system is established to realizeharmless treatment and resource utilization of agricultural wastes, and the Bacillus licheniformis which has an obvious inhibiting effect on strawberry wilt and the one-step through composting fermentation process are connected, so that the special anti-wilt bio-organic fertilizer for strawberries is prepared, and the production process of the bio-organic fertilizer is optimized to reduce the production cost.

Description

technical field [0001] The invention relates to the field of agricultural biotechnology, and more specifically relates to a method for preparing special wilt-resistant bio-organic fertilizer for strawberries from manure of rare breeds (mink, fox, and raccoon dog). Background technique [0002] The development of rare breeds such as raccoon dog, fox and mink has brought about an urgent problem to be solved, which is to deal with the excrement produced in the breeding process of rare breeds such as raccoon dog, fox and mink. [0003] Mink manure is rich in nutrients, metabolizable energy 6.59MJ / kg, crude protein 20.5%, crude fiber 6.9%, calcium 5.69%, phosphorus 3.5%, salt 0.7%, methionine 1.56%, lysine 0.82%, Arginine 0.9%, Threonine 0.54%, Cystine 1.6%, Isoleucine 1.95%. Improper treatment will cause huge pollution to the environment, but the mink manure that has been composted and harmlessly treated can change the content of soil organic matter and the microbial community ...
