Example Embodiment

[0017] Example 1 Eggplant (variety "Xi'an green eggplant") was planted in soils containing Verticillium dahliae for continuous cropping. Seven days after the planting, the preparation of the present invention was used to irrigate around the rhizosphere of the eggplant plant. Apply 150 ml each time, 3 times in a row, once every 7 days, with no application as a control. After the eggplant Verticillium wilt disease plants began to appear in the field, samples were taken every 1 week to investigate the number of Verticillium dahliae in the soil, and the degradation rate of Verticillium dahliae was calculated (see Table 1). It can be seen that for the continuous cropping in the soil for one year The degradation rate of Verticillium dahliae is 85.24%-89.25%, and the degradation rate of Verticillium dahliae in the soil for 2 years of continuous cropping is 81.53%-84.14%, and the degradation rate of Verticillium dahliae in the soil of continuous cropping is 73.74%. -79.28%. Due to the...

Example Embodiment

[0021] Example 2 During the soil preparation in the shed, the planting holes were irrigated with the formulation, and each hole was irrigated with 150 ml at a time. If ditching and planting, the effect of irrigating all in rows is better, and the amount of irrigation should be appropriately increased according to the situation. Then apply 2 times after the eggplant slow seedlings survive. During the growth period, the incidence of eggplant verticillium wilt can be reduced by 80-82%, and the disease index is also significantly reduced (see Table 2).

Abstract

The invention discloses a preparation for degrading Verticilium dahliae in continuous cropping soil of eggplant, and a preparation method thereof. The method is characterized by comprising the following steps: grinding the following raw material components in part by weight: 1 part of asarum, 2 parts of radix sophorae flavescentis, and 2 parts of fructus cnidii with the grinder to the fineness of 40 meshes; fully mixing the three raw materials powder into a mixture, adding 10 parts of water, and pouring the mixture into a sealed plastic bag for decaying at 26 DEG C for 15 days; taking the decayed materials, adding 25 parts of 80 percent ethanol into the decayed materials, fully and uniformly mixing the mixture, keeping the mixture for 36 hours and then fully extracting the mixture; filtering the extract and storing the filtrate in a container; and taking the filtrate, adding 34 parts of water into the filtrate, and diluting and uniformly mixing the mixture to obtain the preparation. The method is characterized by environmental protection, no residue, no pollution to environment and farm products, and capacity of keeping high quality of farm products. The method has the advantages of no requirement of expensive instruments, easily controlled process, stable quality of preparation, low production cost, convenient use, and simple and easily controlled operation. Natural active ingredients in the product can promote growth of vegetables roots, make the plants keep good growth vigor, and is favor of the healthy growth of organs of products.

Description

technical field [0001] The invention relates to the technical field of harmless treatment of soil polluted by harmful microorganisms in vegetable production. Specifically, the invention relates to a preparation and a preparation method for degrading Verticillium dahliae in eggplant continuous cropping soil. Background technique [0002] Verticillium wilt of eggplant is a typical soil-borne disease caused by Verticillium dahliae. The pathogen has a wide range of hosts, many places for overwintering, and a long survival time in the soil (6-7 years). And for many years, due to continuous cultivation (continuous cropping) all the year round, heavy cropping is planted too much, the occurrence of this disease is very common, and the sickness rate of general continuous cropping plot is all at 20%-30%, and severe one never harvests. With the rapid development of vegetable production in my country, especially the continuous expansion of the area of ​​protected vegetables, the phenom...
