But the root-knot nematode control effect of this patent is poor, and the disease removal rate is low
[0006] Patent document 3 discloses the preparation and application method of the plant health-care agent specially for root nematodes, and its formula ratio is in parts by weight: 30-63 parts of EM bacteria, 9-30 parts of Verticillium pallidum, potassium fulvic acid 25-35 parts, 1-6 parts of rooting powder, 0.2-2 parts of chitosan oligosaccharide, 1-2 parts of trace elements, the EM stock solution is composed of photosynthetic bacteria, lactic acid bacteria, yeast, actinomycetes, nitrifying bacteria, Bacillus, 5 families, 10 genera and more than 80 kinds of anaerobic and aerobic microbial flora are compounded. It is a high-quality EM flora produced by Jiangsu Werner Biotechnology Co., Ltd. or commercially available. The Verticillium pachytans described above , it has an effective control effect on root-knot nematodes, but the root-knot nematode control effect of this patent is poor, the disease removal rate is low, and the cost is high

Abstract
The invention discloses a method for preventing and treating plant root-knot nematodes and a fertilizing method. The method for preventing and treating the plant root-knot nematodes comprises the following steps: in a first step (S1), drying vinasse and then crushing the dried vinasse into organic powder; in a second step (S2), uniformly adding 2.08-8.32g of organic powder into each kilogram of soil, and then carrying out irrigation and film coating treatment in the mixed soil; and in a third step (S3), keeping the temperature of the irrigation and coating treatment at 30-35 DEG C and the lasting time of 30 minutes at the daytime, and at night keeping the temperature of the irrigation and coating treatment at 22-28 DEG C and the lasting time of 10-14 hours, wherein the treatment period is15-25 days.
Description
technical field [0001] The invention relates to the field of plant root-knot nematode treatment, in particular to a method for preventing and treating plant root-knot nematode and a fertilization method. Background technique [0002] Plant root-knot nematode (Meloidogyne spp.) is a parasite that parasitizes plant roots and is widely distributed around the world. Currently, there are more than 80 species of root-knot nematodes reported internationally, and 29 species of root-knot nematodes reported domestically. Root-knot nematode has the characteristics of wide distribution, diverse hosts, and strong infectivity. It can infect almost all vegetable crops. Under long-term single continuous cropping, the number of root-knot nematodes in greenhouse soil continues to increase. After annual reproduction, the damage area and degree continue to expand. . The incidence rate of root-knot nematode, a common disease, is 20% to 30%, and the incidence rate of vegetables in serious greenh...
