Saline and alkaline land stock growing method and application

Abstract

The invention relates to the field of plant cultivation, and particularly provides a saline and alkaline land stock growing method and application. A plant pit is provided, a water filter layer, a decaying plant straw layer and a soil improving layer are successively laid on the bottom wall of the plant pit, a waterproof layer and a decaying plant straw layer are successively laid on a side wall of the plant pit, and a tube is inserted in the plant pit. The purpose of reducing saline concentration can be achieved, and time and conditions for stocks to adapt to the environment are provided. Meanwhile, the water filter layer facilitates water drainage; after the decaying plant straw layer are decayed deeply, acid can be formed, and the effect of reducing alkaline concentration of soil is achieved; by the soil improving layer, the survival rate of stocks can be improved while soil quality is improved; and the tubes not only can breath and drain water, but also has a heat-dissipation effect. The stock growing method is simple to operate, the labor and materials are saved, the cultivation cost is low, the method is environmentally friendly, the survival rate of the stock is high, effects of wind prevention and sand fixation are achieved, water resources are improved, and thus, the saline and alkaline land stock growing method can be applied to production and life on a large scale.

Description

technical field [0001] The invention relates to the field of plant cultivation, in particular to a seedling cultivation method in saline-alkali land and its application. Background technique [0002] Soil salinization (soil salinization) refers to the natural geological process in which salt continuously accumulates on the soil surface to form saline soil. Saline soil is formed under certain natural conditions such as climate, topography, land, and hydrological substrate. Human activities, historical floods and droughts, changes in river courses, and land use, agriculture, and water conservancy technical measures have also had a major impact on the occurrence and development of soil salinization. [0003] Generally, the soil with a soluble salt content greater than 0.1% within a thickness of 0.2m in the soil layer is called saline soil. Soil salinization is divided into two types: salinization and alkalization, so it is also called soil salinization. When the neutral salt...
