Control method of plant root rot disease

Abstract

The invention provides a control method of a plant root rot disease. The control method comprises the following specific steps: leveling soil, applying biological organic fertilizer to the soil, uniformly stirring, and then covering with a black mulching film for 7 days; selecting an excellent variety, using 4-5 parts of foliar fertilizer, 0.4-0.5 part of agricultural avermectin and 1000 parts ofwater according to the parts by weight for preparing seed soaking liquid, soaking seeds for 3-5 hours, taking out and sowing; spraying the foliar fertilizer for 5-7 times in the plant growth period, and spraying 100-200 millimeter of foliar fertilizer per mu; and applying amino acid liquid fertilizer to the roots of plants once every 15 days in the seedling stage and vigorous growth period of theplants. The control method has beneficial effects that the organic fertilizer can provide abundant nutrients to crops and promote the growth of plant roots; added beneficial bacteria can effectively inhibit the growth and reproduction of pathogenic bacteria, purify the soil and improve the soil structure; and the control method has a significant effect on the control of the root rot disease.

Description

technical field [0001] The patent of the invention relates to the technical field of agricultural planting, in particular to a method for preventing and treating plant root rot. Background technique [0002] Root rot is a plant disease caused by fungi, nematodes, and bacteria. Root rot is a soil-borne disease, which is mainly transmitted by moisture in the soil, underground insects and nematodes. It mainly harms seedlings and also occurs in adult plants. In the initial stage of the disease, only a few branch roots and fibrous roots are susceptible to the disease, and gradually expand to the main root. After the main root is infected, the early plants do not show symptoms, and as the degree of root rot intensifies, the function of absorbing water and nutrients gradually weakens. Insufficient nutrient supply and demand, the new leaves will turn yellow first, and when the disease is severe, the whole leaves will turn yellow and wither. At this time, the root bark turns brown ...

Problems solved by technology

[0003] The traditional control methods of plant root rot include agricultural control and root irrigation treatment. The main way of agricultural control is intensive cultivation of land, pay attention to drainage, deep plowing of soil, and improvement of soil permeability; Polymyxa polymyxa root irrigation or rooting agent plus hymexazol and metalaxa hymexazol root irrigation control, 7 to 10 days, but the above methods have certain limitations, the intensive cultivation of traditional control methods is time-consuming and laborious, resulting in Increased labor costs; drug root irrigation, although killing pathogenic fungi in a short period of time, also kills beneficial fungi, resulting in reduced soil vitality. At the same time, the application of a large amount of nitrogen fertilizer soil is easy to harden and has poor permeability, which is not conducive to the growth of plant roots. permanent cure
