Beet continuous cropping resisting agent and preparation method

Abstract

The invention discloses a beet continuous cropping resisting agent and a preparation method thereof. The beet continuous cropping resisting agent comprises continuous cropping resisting compound powder and compound bacterium liquid, and the compound bacterium liquid is evenly sprayed to the surface of the continuous cropping resisting compound powder and stirred to obtain a finished product. The preparation method comprises the following steps: S1, preparation of the continuous cropping resisting compound powder, S2, preparation of the compound bacterial liquid, and S3, preparation. The beet continuous cropping resisting agent and the method have the advantages that on the basis of biological prevention and treatment, the continuous cropping resistant microbial agent and the 5% abamectin emulsifiable concentrate are combined through a chemical prevention and treatment means, an ideal effect can be achieved through one-time spraying, the continuous cropping resistant effect is improved,and the crop morbidity can be controlled to be about 6%; on the basis of biological control, a compound microbial fertilizer and a polyglutamic acid solution having a concentration of 3% are added, rich nutrient substances are provided for crops, the resistance of the crops is improved, the yield of the crops can be increased while continuous cropping is resisted, and the yield increase rate canreach 24%; various microorganisms are added, and after spraying, the microorganisms survive and propagate in the soil, so that the soil condition is improved, soil hardening is prevented and controlled, and the organic matter content in the soil is increased.

Description

Technical field: [0001] The invention relates to the field of anti-cropping agents, in particular to a sugar beet anti-cropping agent and a preparation method. Background technique: [0002] In order to meet the demand of agricultural production and supply in our country, in view of the fact that the per capita agricultural land is less, increasing the multiple cropping index (double cropping) is the only way to solve the problem. However, with the continuation of heavy cropping, many crops, such as sugar beet, leguminous plants, melons, vegetables, strawberries, etc., are caused by the accumulation of plant root pathogens due to heavy cropping, resulting in plant wilt, leaf blight, viral diseases, etc. Occurs, seriously affects the growth of crops, and causes large-scale production reduction and extinction of crops. For example, sugar beet planting generally has a morbidity rate of 30-50% due to heavy cropping. The plants often die, resulting in lack of seedlings and broke...

Problems solved by technology

Among them, agricultural control has limitations. Because agricultural cultivation needs to follow the local climate conditions, it is impossible to prevent heavy cropping through agricultural control methods such as crop rotation and inversion in some areas; chemical control has the advantages of significant and rapid control effect, but its environmental compatibility is poor , long-term use will easily cause problems such as soil microbial imbalance, low fertilizer utilization rate, and soil compaction, which will cause pathogens to develop drug resistance and reduce the control effect; biological control through antagonism, competition, induced resistance and parasitism between microorganisms Interaction to control cropping diseases is a control method with great potential. However, the anti-cropping fungicides currently on the market have a single strain and a low number of effective viable bacteria, which is not ideal for the control of cropping diseases.
