Abstract

The invention provides a root-divided alternative irrigation method by adopting a fly ash salt-isolation layer. The root-divided alternative irrigation method comprises the following steps: laying of the salt-isolation layer, laying of a water pipe, and root-divided alternative irrigation, wherein the salt-isolation layer successively comprises, from bottom to top, a tree leaf layer, a rough stone layer, a miscanthus sacchariflorus stalk layer, a fine stone layer and a fly ash layer; the tree leaf layer comprises cornus controversa leaves; the rough stone layer comprises zeolite, gravels and pebbles; the fine stone layer comprises wheat bran and desulphurized wastes; and the fly ash layer comprises fly ash and fermented sheep manure. The invention also provides an application of the root-divided alternative irrigation method by adopting a fly ash salt-isolation layer in plantation of malus micromalus in saline-alkali soil. By using the root-divided alternative irrigation method provided by the invention, the usage amount of fresh water is greatly reduced, and the usage amount of the fresh water is reduced by 70% to 80% than the usage amount of ordinary irrigation fresh water; meanwhile, the water utilization rate of irrigation water is increased to 90% or above; the contents of nutrient components in fruits are increased, and high edibility is achieved; and salt deposit and salt return of a soil root layer in a planting region are restricted at the same time.

Description

technical field [0001] The invention belongs to the technical field of irrigation, and in particular relates to a root-splitting alternate irrigation method using fly ash to separate salt layers and its application in planting crabapple in saline-alkali land. Background technique [0002] The so-called saline soil mainly refers to the soil containing excessive water-soluble salt in the soil, which is mostly neutral salt, showing alkaline reaction, and the pH value is between 7 and 8. Salt damage is mainly caused by excessive concentration of sodium ions (Na+). Saline soil generally has no obvious structure in the profile of the soil. In the dry season, especially in places where there is no plant growth, the topsoil is often white, and even forms a salt crust. Saline soil can be divided into coastal saline soil, alluvial saline soil, marsh saline soil, meadow saline soil and so on. Coastal saline soil is mainly formed by the influence of seawater. Saline soil and saliniz...
