Abstract

The invention belongs to the technical field of land improvement, and in particular relates to a method for improving seashore saline land by plant intercropping. The method comprises the steps of: S1, turning over and leveling the saline land by adopting a deep plow harrow before planting, and digging drainage ditches; S2, throwing a mixed material into soil, turning over and leveling the salineland again, separating the land by ridges having widths of 1-1.5m, and digging holes at fixed points according to the size on the planted land with determined row spacings, wherein the rows are parallel, the diameters of the holes are 10-25 cm, and the plants are spaced (0.2-0.5) m * (0.2-0.5) m; S3, putting the soil in the holes into a crusher, crushing the soil and then filling the soil back into the holes; S4, putting wormcast to the bottoms of the holes, and then putting seedlings or treated seeds; and S5, regularly watering. The method can effectively improve the water retention, drainageand fertilizer retention of the soil and improve the survival rate of plants; and the method adopting plant intercropping can effectively regulate the pH value of the soil.

Description

technical field [0001] The invention belongs to the technical field of land improvement, and in particular relates to a method for improving coastal saline-alkali land by plant intercropping. Background technique [0002] Saline-alkali land is the general term for salt land and alkaline land. The distribution area of ​​saline-alkali land in my country is relatively wide, about 100 million hectares. According to the change of soil type and climatic conditions in my country, the distribution area of ​​saline-alkali soil includes coastal saline area, Huanghuai-Hai plain saline area, desert and desert grassland saline area, and grassland saline area. There are four types of stain areas. Among them, coastal saline-alkali land is an important type of saline-alkali land in my country, with a coastline of more than 18,000 kilometers and a wide distribution. The problems of land salinization and secondary salinization in coastal areas are very serious, and excessively high soil sali...
