Problems solved by technology

[0003] At present, there is no effective control method for pepper bacterial wilt. Resistant varieties are the most effective way to control bacterial wilt. However, due to the host diversity and genome variability of bacterial wilt pathogens, the resistance of resistant varieties is often caused loss, while the single application of biological agents and chemical agents is not effective

Embodiment 1

[0017] A method for controlling capsicum bacterial wilt, comprising the steps:

[0018] (1) Soil improvement: add a mixture of quicklime powder and soybean meal to the pepper planting land, the dosage is 200kg per 667m2, and then deep plow the soil before winter;

[0019] (2) Balance soil nutrients: Apply 105kg of special-purpose fertilizer to the improved soil, and then apply 15kg of special-purpose fertilizer to the hole before transplanting. The "Best" organic-inorganic compound fertilizer produced by Best Organic Active Fertilizer Co., Ltd. has a mass percentage of organic matter ≥ 25%, a mass ratio of nitrogen, phosphorus, and potassium of 7:6:7, and contains boron, zinc, and magnesium. ;

[0020] (3) Seedling stage treatment: before transplanting, dip the roots with a 30-fold bacterial solution of 50,000 to 100,000 cfu / gram Paenibacillus polymyxa or 1 billion cfu / gram marine Bacillus, and then use Zhongshengmycin at the initial flowering stage The mixed medicinal solut...

Abstract

The invention discloses a method of controlling pepper bacterial wilt. The pepper bacterial wilt is prevented and controlled through soil improvement, soil nutrient balancing, and a seedling stage resistance induction processing system; To be specific, soil amendment is added to cultivation land for peppers and then deep tillage on soil is performed before winter; then special fertilizer is applied in the improved soil and hole application of special fertilizer is performed before seedling stage transplantation; pepper roots are dipped in bacteria liquid of Paenibacillus polymyxa or marine bacillus before transplantation; then root-irrigation processing is performed with mixed solution of zhongshengmycin and thiediazole copper at early blooming period for 2 to 3 times and every 7 to 10 days each time. The use of the method disclosed in the present invention can delay the outbreak of pepper bacterial wilt and increase the yield of pepper, improve the quality of pepper and improve the soil, and can be widely used in pepper planting industry.

Description

technical field [0001] The invention belongs to the field of crop disease prevention and control, and relates to a method for controlling capsicum bacterial wilt. Background technique [0002] Pepper bacterial wilt is a typical bacterial soil-borne disease caused by Ralstia solanacearum ( Ralstonia solanacearum ), the disease is distributed in most areas such as East China, Central China, and Southwest my country. After the onset, about 30% of peppers died, causing great losses to agricultural production. The main factors for the occurrence of bacterial wilt include: soil, climate, fertilizer and fertilization measures, water conservancy conditions and drought and flood resistance measures and other environmental conditions; soil pathogen accumulation; disease resistance of pepper varieties; growth and development status and root system development; fertilization Factors such as level and type of fertilizer. With the increase of capsicum planting years, soil acidification...
