Problems solved by technology

The growth and development of diseased plants are severely hindered, which greatly affects the yield of strawberries
[0003] Although a variety of microorganisms have been confirmed to have antagonistic effects on Phytophthora fragariae, such as Bacillus amyloliquefaciens (Bacillus amyloliquefaciens), Pseudomonas fluorescens (Pseudomonas fluorescens) and Arbuscular mycorrhiza (Arbuscular mycorrhiza), etc. There are few biological products for the treatment of strawberry root rot, and most of them have problems such as poor therapeutic effect, easy to be affected by the environment and low product promotion rate

preparation example Construction

[0081] According to a second aspect of the present invention, there is provided a method for preparing a composite microbial inoculum, comprising the following steps: mixing Trichoderma, Bacillus, Penicillium, actinomycetes and carriers uniformly in proportion to obtain a composite microbial inoculum .

[0082] The preparation method of the composite microbial bacterial agent has simple process, convenient operation and convenient industrial application.

[0083] According to the third aspect of the present invention, the application of the compound microbial agent in the prevention and treatment of plant root rot is provided; the preferred plant is strawberry.

[0084] In the application of compound microbial bacterial agent in the prevention and treatment of plant root rot, you can choose how to use it according to actual needs. For example, you can treat crops by seed treatment, soil spraying or irrigation. The control effect of compound microbial bacterial agent on strawb...

experiment example

[0095] 1. Experiment site selection and design

[0096] The experiment was carried out in a strawberry greenhouse in Dongjia Town, Jinan City, Shandong Province. The experiment was carried out in September 2017. There were 5 treatments in total, each treatment had 3 repetitions, and each treatment was randomly assigned.

[0097] Second, the test drug

[0098] The microbial agents provided in Examples 1-12 and Comparative Examples 1-5 were respectively diluted 500 times as the treatment group, and sprayed with clear water was used as the control group in the test.

[0099] 3. Drug application

[0100] Spray each treatment on the strawberry leaves, once every half a month, and 5 times throughout the growing season, with spraying water as a control. After slowing down the seedlings, enter the flowering and fruit-setting period, and measure the morphological indicators as soon as the strawberry seedlings enter the flowering period, green fruit period, ginkgo fruit period, and r...

Abstract

The invention discloses a compound microbial agent as well as a preparation method and an application thereof and relates to the technical field of microbial agents. The microbial agent is prepared from components in parts by weight as follows: 20-40 parts of trichoderma, 30-75 parts of bacillus, 3-8 parts of penicillium, 5-10 parts of actinomyces and 25-50 parts of a carrier. By cooperation of all stains, reasonable matching of content and addition of the carrier, the compound microbial agent has the advantages of high activity, high stability and good effects of controlling plant root rot and promoting plant growth. The preparation method of the compound microbial agent is simple in process and convenient to operate and facilitates industrial application. Besides, the invention also discloses an application of the compound microbial agent in control of the plant root rot.

Description

technical field [0001] The invention relates to the technical field of microbial inoculum, in particular to a composite microbial inoculum and its preparation method and application. Background technique [0002] Plant root rot is a plant disease caused by fungi. The disease will cause root rot, the function of absorbing water and nutrients will gradually weaken, and finally the whole plant will die. The main symptoms of the disease are yellowing and withering of the leaves of the whole plant. Strawberry red center root rot, also known as strawberry red heart root rot, is the main disease of strawberries in cold and humid areas. The incidence is more serious in paddy and dry rotation fields and old production areas. It has become a devastating root disease that is difficult to control among strawberry diseases. one. Strawberry root rot is mainly caused by host-specific Phytophthora fragariae infection. The root system begins to darken and soften from the tip of the young ro...
