Disease-resistant, wireworm-resistant seedling raising matrix and production method thereof

Abstract

The invention relates to a soilless seedling culturing substrate for resisting diseases and root nematode of plants and a production method thereof. In the invention, organic wastes such as straws are taken as raw materials, inoculated with zymogen according to certain proportion, subjected to moisture content regulation, evenly mixed and stacked for primary fermentation; when the temperature of a pile reaches 60 DEG C, the pile is turned; the pile is turned and oxygen and moisture content are supplemented every seven to ten days afterwards; after the pile is turned for three times, when the temperature is lower than 35 DEG C, the pile is inoculated with a bio-antagonist for secondary fermentation, turned every three to four days and kept at a temperature of between 35 and 40 DEG C; and after 15 to 20 days, the seedling culturing substrate containing the 108 / gram bio-antagonist is obtained. The seedling culturing substrate has chemiotaxis for interfering pathogenicbacteria and nematode, can reduce infestation chance of the pathogenicbacteria and nematode on the root surface, and has double effects of resisting phytophthora disease and root nematode disease through the secondary fermentation and microorganism activation technology.

Description

technical field [0001] The invention relates to a seedling raising substrate for plant disease resistance and root nematode resistance soilless cultivation and a production method thereof. Background technique [0002] With the rapid development of protected horticulture, soilless culture technology and plug seedling technology are being popularized and applied on a large scale, which quickly promotes the research, development and application of solid cultivation substrates. [0003] In the developed countries of protected horticulture, such as the Netherlands, the United States, the United Kingdom, and Japan, there are specialized substrate research and development institutions and production enterprises. The Dutch succeeded in growing crops with rock wool, which was later popularized and applied worldwide. However, rock wool cannot be reused after a few years of use. It is difficult to dispose of waste rock wool, and it has become a public hazard in the Netherlands. Some ...

Problems solved by technology

The research and development of bio-control bacteria in foreign countries mainly focus on the direction of bio-pesticides. According to new investigations, there are no reports on the application of seedling substrates and disease-resistant production.
