Abstract

The invention relates to a resin detoxification, desalination and degerming technology for preventing and controlling continuous cropping obstacles of facility cultivation crops and application, and belongs to the field of agriculture and environmental protection. The technology comprises the following implementation steps that on the facility cultivation continuous cropping obstacles for many years, groundwater wells are dug, anion-cation resin columns are adopted for preventing and controlling the continuous cropping obstacles, groundwater is pumped out, salt, especially sodium ions, in thegroundwater, harmful microorganisms in continuous cropping soil and allelochemical substances and / or autotoxins in the continuous cropping soil are adsorbed and filtered out by special ion exchange columns, harmful heavy metal ions and organic pesticides in the soil can be adsorbed and filtered out at the same time, the surface of the facility soil is irrigated with filtered clean water, the sodium ions, harmful microorganisms and allelochemical substances and / or autotoxins of a soil tillage layer are eluted, continuous cropping obstacle factors of the facility cultivation crops are eliminatedaccordingly, the soil is remediated, the production and ecological functions of the soil are restored, the healthy growth of the crops is ensured, convenience is provided for farmers to produce green, pollution-free and high-quality agricultural products, and the sustainable development is facilitated.

Description

technical field [0001] The invention belongs to the fields of agriculture and environmental protection, and in particular relates to a resin detoxification, desalination and bacteria removal technology for preventing and controlling obstacles to continuous cropping of facility cultivated crops. Background technique [0002] Protected cultivation agriculture, also known as off-season cultivation, can grow plants in colder weather that is not suitable for planting, which has changed the traditional planting methods and habits. As of 2018, my country's protected cultivation area is 60 million hectares, creating a value of 1.5 trillion yuan, which meets the needs of the people's food basket. [0003] Due to the high comparative economic benefits of protected cultivation, farmers usually carry out long-term continuous cropping for many years, resulting in serious obstacles to continuous cropping in protected cultivation, outbreaks of pests and diseases, serious secondary saliniza...
