Slow-release long-acting biological bacterial fertilizer for controlling eggplant root rot

Abstract

The invention discloses a slow-release long-acting biological bacterial fertilizer for controlling eggplant root rot. The formula of the biological bacterial fertilizer comprises the following components by weight: 30-70g of loofah sponge, 20-30 parts of aloe, 20-40 parts of chrysanthemum coronarium, 30-60 parts of carpesium abrotanoides, 65-80 parts of daisy, 20-30 parts of artemisia scoparia, 40-50 parts of sophora alopecuroide, 20-40 parts of bone meal, 40-60 parts of wheat bran, 30-60 parts of a nitrogen-phosphorus-potassium ternary compound fertilizer, 50-70 parts of humic acid, 30-50 parts of livestock excrement, 5-10 parts of hexacyclic stone and 0.3-1.5 parts of a microbial agent. Specifically, the biological agent is prepared from yeast, trichoderma viride and non-pathogenic fusarium in a mass fraction ratio of (1-3):(2-4):(2-3); the total concentration of living bacteria of the biological agent finished product is 1*10<10>-1*10<12>cfu / ml. The invention also discloses a preparation method of the biological bacterial fertilizer. The formula provided by the invention is ecologically environment-friendly, avoids the use of chemicals, eliminates residual pesticides and harmfulsubstances in crops, improves the water and fertilizer retention performance of soil, and reduces soil hardening.

Description

technical field [0001] The invention relates to the technical field of vegetable planting, in particular to a slow-release long-acting biological bacterial fertilizer capable of preventing and treating eggplant root rot. Background technique [0002] Eggplant is an important solanaceous vegetable, which is planted in a large area across the country and is one of the vegetables with high economic value. In the process of eggplant planting, the root and stem of eggplant are often caused by Fusarium, Verticillium dahliae and other pathogens to wither and rot, resulting in a large area of ​​dead eggplant. When the disease occurs, the leaves will wither during the day, and they can recover sooner or later. After repeated for many days , the leaves begin to turn yellow and dry. At the same time, the epidermis of the root and stem base is brown, the epidermis of the primary root or branch root is brown, the cortex is damaged or rotted, and the capillary root is rotten, resulting i...

Problems solved by technology

[0004] At present, there are many ways to prevent and control diseases of eggplant root rot, but many of them are based on chemical spraying, and the control effect is not good enough, which is not ideal.

At the same time, each disease of root rot is divided and conquered, and the cost of prevention and control is increased instead.
