Problems solved by technology

②Soil nutritional conditions become poor
Under the influence of drainage, salt washing and increased quota irrigation, the loss of soil nitrogen is serious. Organic matter is the main source of soil phosphorus. The decomposition products of organic matter can release phosphorus and improve its effectiveness. The content of organic matter in saline-alkaline soil is low. The content of available phosphorus is low. In addition, the pH value of saline-alkali land is high and the content of calcium carbonate is high. Phosphorus in the soil is easy to form insoluble phosphate, thereby reducing the availability of phosphorus. In addition, trace elements such as zinc, manganese, iron, and copper Both are also less effective due to high soil pH
③ Poor soil physical properties
[0004] Then there are problems such as slow growth of trees and low survival rate of transplanting in planting ash trees on saline-alkali land

Abstract

The invention relates to a method for planting fraxinus chinensis on saline-alkali land and belongs to the technical field of forestry. The method can remove the influence of the saline-alkali soil to fraxinus chinensis when the fraxinus chinensis is planted on the saline-alkali soil. According to the method, a three-dimensional planting structure suitable for drainage and water retention is constructed, so that the fraxinus chinensis is not easily affected by alkaline and saline substances in the saline-alkali soil, and a pH-sensitive water retention gel and nutrient soil are mixed and provide a good living environment for the fraxinus chinensis.

Description

technical field [0001] The invention relates to a method for planting white wax on saline-alkali land, which belongs to the technical field of forestry. Background technique [0002] Salinization makes the physical and chemical properties of soil worse, and the living conditions of crops, forest trees and pastures deteriorate. Due to the salinization of the soil, the process of soil grassing and the accumulation of soil organic matter are inhibited, so the content of soil organic matter is relatively reduced, thus affecting the physical and chemical properties of the soil. ②Soil nutritional conditions become poor. Under the influence of drainage, salt washing and increased quota irrigation, soil nitrogen loss is serious, organic matter is the main source of soil phosphorus, and the decomposition products of organic matter can release phosphorus to improve its effectiveness. The content of organic matter in saline-alkali soil is low. The content of available phosphorus is a...
