Organic matter basis cultivation method for vegetable overcoming root-knot nematodiasis of soil

Abstract

The invention relates to a vegetable organic substrate culturing method which overcomes the root knot nematode disease, etc. of greenhouse soil. The culture troughs of the culturing method are open soil troughs not isolated from the soil; the spacing between the two troughs is about 1.5cm; the upper opening width of each trough is 25cm to 35cm, the bottom width is 20cm to 30cm, and the depth is 20cm to 30cm; the three optional substrate culturing prescriptions of the culturing method by the volume ratio are as follows: prescription 1: rice hull: fermented excrement: riversand =2: 1:1; prescription 2: decayed dairy manure: rice hull: riversand =5: 4:1; prescription 3: corn or wheat straw fermented materials: decayed excrement (or sheep manure): riversand =4: 1: 1. After the troughs are dug according to the specification, the cultured substrate is filled in the troughs, i.e. tomato, watermelon and other vegetables can be colonized in the culture troughs. The soil root knot nematode does not invade the cultured substrate with main roots of vegetables are distributed in; therefore, the method can effectively overcome the harm of the greenhouse soil root knot nematode to the vegetables. The cultured substrate essentially consists of rich hull, dairy manure, crop straw, excrement and other agricultural waste, has the advantages of easily available materials and low cost, can be fertilized to the field as fertilizer after being used to fertile the soil, and does not pollute the environment.

Problems solved by technology

[0002] Solar greenhouses and plastic greenhouses have become the most important off-season vegetable production facilities in my country. However, due to years of continuous cropping, soil obstacles such as root-knot nematodes have become increasingly serious, and have become the main limiting factors for the high-quality and efficient production of facility vegetables.

Soilless cultivation is the fundamental method to solve this problem, but the traditional nutrient liquid soilless cultivation technology is difficult to master, the input cost is high, the product has high nitrate content, and it does not meet the production requirements of green food, etc., so it is difficult to use it on a large scale in production application

The currently applied organic matrix soilless cultivation technology overcomes the above shortcomings to a certain extent, but because the cultivation tank is separated from the soil by plastic film, it is easily affected by unfavorable factors such as uneven water supply and inhibited root growth, and it is difficult to obtain vegetables. High quality, high efficiency and high yield
