Fast acidified soil ecological restoration agent for preventing and controlling successive cropping obstacles of melons and restoration method

Abstract

The invention discloses a fast acidified soil ecological restoration agent for preventing and controlling successive cropping obstacles of melons and a restoration method, the fast acidified soil ecological restoration agent includes the following components by mass: 80-90 parts of silkworm excrement, 10-20 parts of bone meal and 0.1-0.3 part of a yeast agent, the yeast agent comprises Saccharomycopsis fibuligera. The ecological restoration method comprises the following steps: cleaning, spreading materials, preparing lands, ditching, irrigating, coating the surface of the soil layer with a film, keeping close at above 20 DEG for 10-15d, uncovering the film, turning the soil over for planting of the melons. The fast acidified soil ecological restoration agent aiming at the defects of prevention and control technologies in the prior art, from a technical point of view of ecological restoration of soil, soil acidification can be improved in a short period of time, salinization can be reduced, pathogenic microbes in the soil can be effectively killed, controlling successive cropping obstacles of the melons can be eliminated, the normal production of the melons can be ensured.

Description

technical field [0001] The invention relates to the technical field of soil ecological restoration, specifically an acidified soil rapid ecological restoration agent and restoration method for the prevention and control of continuous cropping obstacles of melons, an ecological prevention and control technology capable of eliminating the obstacles of continuous cropping of melons, and is specially used to overcome and eliminate the obstacles of continuous cropping of crops. Background technique [0002] my country is the largest melon planting country in the world. According to the statistics of the "China Watermelon and Melon" magazine, in 1989 the planting area of ​​melons reached about 107,000 hectares; after the 1990s, with the promotion and development of cultivation in protected areas, the area of ​​melons increased by leaps and bounds. It is estimated that the total area of ​​melons in the country has reached 200,000 to 250,000 hectares, ranking first in the global mel...

Problems solved by technology

Although many domestic research institutions have done a lot of research work on the breeding of crop disease-resistant varieties, the current disease resistance needs to be improved, and the decline in disease resistance caused by pathogenic bacteria mutations can easily lead to a high incidence of Fusarium wilt. Many melons and fruits Vegetables still lack effective disease-resistant germplasm resources

However, high-efficiency but highly toxic chemical disinfectants such as methyl bromide have seriously damaged the soil ecology, have hidden dangers of pollution to agricultural products, and are prone to produce drug resistance, so they have been banned; biological control has made some research progress, but the effect still needs to be improved, and it is difficult to effectively improve occurrence of blight

Moreover, most of the current research on fusarium wilt control technology focuses on a single technology, a single link, and a single area, and seldom focuses on soil restoration, regulation of soil micro-ecological environment, maintenance of soil health, prevention of soil quality degradation, and realization of sustainable soil productivity. It is difficult to fundamentally prevent the degradation of soil quality and the occurrence of blight diseases
