Problems solved by technology

However, its control effect is often unstable, which may be related to the fact that the soil environment after continuous cropping is not necessarily suitable for the growth of exogenously added antagonistic microorganisms, and these exogenously added antagonistic microorganisms also need to compete with indigenous microorganisms for nutrients and ecological niches (WeiZ, Yang TJ, Friman VP, et al.Trophic network architecture of root-associated bacterial communities determines pathogen invasion and plant health[J].Nature Communications, 2015, 6)
Therefore, the method of exogenously adding antagonistic microorganisms may work well in some soil conditions, but it is not universally applicable
In addition, in the process of planting cruciferous vegetable crops, it is necessary to supplement the antagonistic microorganisms multiple times to enhance the control effect, but it also greatly increases the production cost

[0038] 2. Preparation of organic preparations

[0039] 2.1 Preparation of Bagasse Organic Preparations

[0040] 1) The bagasse is thoroughly crushed to a particle size of 2 mm to 100 mm and used as a solid raw material for organic preparations. The technical indicators of the solid organic raw material are: moisture: 10%; total organic carbon TOC: 40%; total organic nitrogen TN: 0.4 %, easily oxidizable carbon EOC: 8%.

[0041] 2) Mix special microorganism Bacillus (Bacillus amyloliquefaciens) and Aspergillus in a mass ratio of 50:50 as ingredients for promoting decomposition.

[0042] 3) In terms of mass percentage, the above-mentioned decomposition-promoting ingredients are 1%, and the balance is solid organic raw materials;

[0043] The above-mentioned raw materials are mixed at a rotating speed of 100-200 rpm, dried at 70-100° C. for 10-60 minutes, and then naturally cooled at room temperature for 10-60 minutes to obtain an organic bagasse preparation.

Embodiment 1

[0051] Using the bagasse organic preparation obtained in 2.1 to conduct an experiment on the control effect of clubroot in the kale soil of continuous cropping for seven years 1) General situation of the test site

[0052] The test is located in the kale production base of Yunnan Hengjin Agricultural Development Co., Ltd., Bajie Town, Anning County, Kunming City, Yunnan Province. The base has seven years of kale cultivation history, and 7 to 8 crops of kale are planted every year. , That is, the phenomenon of clubroot appeared. During this period, various prevention and control measures were adopted, but the prevention and control effects were not good. Before the experimental treatment, the incidence of clubroot in Chinese cabbage was as high as 60%, and the yield of Chinese cabbage was severely reduced. The basic physical and chemical properties of the 0-20cm soil layer before the test were pH 6.80, organic carbon 35.1g / kg, total nitrogen 2.88g / kg, ammoniacal nitrogen 2.23mg...

Embodiment 2

[0066] Using the organic preparation of molasses obtained in 2.2 to conduct an experiment on the control effect of clubroot in the kale soil of continuous cropping for seven years 1) General situation of the test site

[0067] The experimental site profile is as described in Example 1.

[0068] 2) Experimental design

[0069] Two treatments were set up in the field test: 1) the control (CK) without any soil treatment; 2) the treatment of organic molasses preparation, that is, the soil of the plow layer (0-30cm) was first turned by a root-rotator to make it evenly mixed , and then evenly sprayed on the surface of the soil to be treated by sprinkling irrigation at a rate of 400kg / mu, irrigated to the maximum water holding capacity in the field and covered with film (MO). Each treatment was repeated 3 times and distributed according to random arrangement. The area of ​​each plot is 120m 2 (3m×40m), and each plot is separated by a cement ridge 60cm deep and 20cm wide. The anae...

Abstract

The invention belongs to the technical field of agricultural sustainable development, relates to preparation of organic preparations and in particular relates to an organic preparation for controllingcruciferous vegetable club root and application thereof. The organic preparation is composed of organic raw materials and decomposition-promoting ingredients, wherein the organic materials include but not limited to one or more of crop straws, saw dust and other solid organic materials and molasses, alcoholic fermentation liquor and other liquid organic materials; the decomposition-promoting ingredients include but not limited to one or more of special microbes and organic catalysts; and a ratio (mass) of the organic raw materials to the decomposition-promoting ingredients is (95-100):(5-0).The invention further discloses a preparation method and application of the organic preparation. The organic preparation disclosed by the invention is ecologically environment-friendly and is applicable to soil with high incidence of club root after continuous cropping of various cruciferous vegetables. The quantity of plasmodiophora brassicae woron in soil and the incidence rate of the club rootof crops can be effectively reduced after treatment, the sterilization rate and the club root control rate respectively reach 60-90%, and the yield of the crops is obviously increased.

Description

technical field [0001] The invention belongs to the technical field of sustainable agricultural development and relates to the preparation of organic preparations, in particular to an organic preparation for preventing and controlling cruciferous vegetable clubroot and its application. Background technique [0002] Cruciferae (Cruciferae) vegetable crops are the most important vegetable crops in my country. There are many kinds of them, mainly including cabbage, cabbage, mustard greens and aquatic vegetables. Among them, Chinese kale and broccoli are not only rich in nutrition, but also can prevent various diseases such as esophageal cancer and bladder cancer, so they are deeply loved by the public. With the improvement of people's living standards, the consumption of cruciferous vegetables has increased year by year, which has promoted the development of cruciferous vegetables from the traditional planting mode to the large-scale and intensive planting mode.
