Embodiment 1

[0038] A kind of bio-organic fertilizer with the function of preventing and controlling anthracnose of Chinese cabbage is obtained through the production method of following steps:

[0039] 1. Preparation for stockpiling

[0040] Animal manure such as pig manure, chicken manure or cow manure and plant residues such as hay, branches or straw are crushed and mixed at a mass ratio of 3.5:1, and the moisture content of the pile is adjusted to 60%, and stored for later use.

[0041] 2. Preparation of mixed bacterial solution and poly-γ-glutamic acid solution:

[0042] Cultivation of antagonistic Paenibacillus polymyxa ABTNL-X1 and Bacillus subtilis ABTNL in liquid medium -2 , mixed in equal proportions to prepare a mixed bacterial solution; the preparation concentration was 200mg L -1 solution of poly-gamma-glutamic acid.

[0043] Among them, the liquid medium is prepared by dissolving 10.0g of sodium chloride, 10.0g of tryptone, and 5.0g of yeast powder in 1L of distilled water...

Abstract

The invention provides a bioorganic fertilizer with a Bok choy anthrax control function. The raw materials of the bioorganic fertilizer comprise Paenibacillus polymyxa, Bacillus subtilis, a compost produced from animal manure and plant residues, and a poly(gamma-glutamic acid) solution. The invention also provides a preparation method of the bioorganic fertilizer. The preparation method comprises the following steps: inoculating he compost produced from the animal manure and the plant residues with a mixed bacterial liquid prepared after culturing and activating two antagonistic bacteria comprising Paenibacillus polymyxa and Bacillus subtilis, carrying out fermentation to obtain a decomposed product, adding the a poly(gamma-glutamic acid) solution, and drying the obtained mixture in a shady place to prepare the bioorganic fertilizer with a Bok choy anthrax control function. The bioorganic fertilizer prepared in the invention has a substantial control effect on Bok choy anthraxes; and the preparation method of the product has the advantages of simplicity, wide sources of the raw materials, and low production cost, and is suitable for large-scale production of the bioorganic fertilizer with the Bok choy anthrax control function.

Description

technical field [0001] The invention relates to the field of bio-organic fertilizers, in particular to a bio-organic fertilizer capable of preventing and controlling anthracnose of Chinese cabbage and a preparation method thereof. Background technique [0002] Bok choy (Bok choy) is a herbaceous plant of Brassica genus Brassicaceae with leaves as its product. It is an important vegetable crop in the world. It is native to the Mediterranean coast and China. China has the largest cultivation area and the highest total output. Cabbage anthracnose is a worldwide disease caused by Higgins anthracnose fungus (Colletotrichum higginsanum Sacc.). Easier to be popular. Anthracnose of pakchoi is one of the main diseases of pakchoi, which can lead to a substantial reduction in the production of pakchoi, and severe fields are almost impossible to harvest. [0003] At the same time, with the separation of aquaculture and planting in our country, there is not enough farmland to absorb a ...
