Abstract

The invention relates to the technical field of avoiding damage to plant roots due to back-salt and improving extremely degraded saline-alkali land, and in particular relates to a plant cultivation system and method for preventing salt damage and maintaining water and fertilizer. The core of the system is the root housing: the root housing is a hollow shell with openings at both ends; the cross-sectional area of ​​the middle part of the root housing is larger than the cross-sectional area of ​​the openings at both ends; the root housing is used to be placed in the soil to wrap the plants the roots. The root storage part is buried in the soil, and then the soil in the root storage part is sprayed with water several times, and the salt is leached out through the salt-reducing aperture and the salt is prevented from rising, so as to minimize the soil salinity in the root storage part and create an environment suitable for plant growth. environment, so as to avoid the damage of plant roots due to returning salt, and also provide an effective technical method for crop cultivation in extremely degraded saline-alkali land.

Description

technical field [0001] The invention relates to the technical field of avoiding damage to plant roots due to back-salt and improving extremely degraded saline-alkali land, and in particular relates to a plant cultivation system and method for preventing salt damage and maintaining water and fertilizer. Background technique [0002] In today's society with a growing population, in order to meet the needs of human survival, human beings have fully developed arable land resources, and the further improvement of conventional arable land productivity is facing a bottleneck, which can no longer meet human needs. The improved utilization of saline-alkali land and desertified land has important practical significance for increasing the land area and improving the agricultural productivity of cultivated land. [0003] In related technologies, biological improvement is a conventional method for improving saline-alkali land, but due to the limitation of the range of biological physiolo...
