Problems solved by technology

[0004] 1. With the existing irrigation method, the adaptability of the plant root system is poor, and the growth is average in the soil with low water content. At the same time, the plant root system develops slowly and the growth rate is slow;
[0005] 2. Using existing irrigation methods, the amount of fresh water used for irrigation is high, and fresh water is wasted more;
[0006] 3. Plants grown using existing irrigation methods have less medicinal ingredients and low medicinal value
[0007] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve

Abstract

The invention provides a root-divided alternative irrigation method with a sepiolite salt partitioning layer. The root-divided alternative irrigation method includes the steps of water pipe laying, and further includes the steps of salt partitioning layer laying; the salt partitioning layer sequentially comprises a leak-proof layer, a rough stone layer, a fine stone layer and a nutrition layer from bottom to top. The invention further provides an application of the root-divided alternative irrigation method with the sepiolite salt partitioning layer to planting casuarina equisetifolia in saline-alkali land. The root-divided alternative irrigation method is adopted, the adaptive capacity of plant roots is also greatly enhanced, and the growth vigor in soil with the water content of 10.0% to 11.0% is good; meanwhile, the plant roots are good in development and high in growth speed; compared with the common fresh water irrigation amount, the per-mu fresh water irrigation amount is reduced, and the saved fresh water amount reaches 60% to 70%; the content of the medicinal components in plants is increased, and the medicinal value of the plants is greatly improved.

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 sepiolite to separate salt layers and its application in planting casuarinas in saline-alkali land. Background technique [0002] In recent years, due to the irrational development and utilization of water resources, the precipitation is small but the evaporation is large, and soil salinization has increased, resulting in the continuous expansion of land desertification in most areas, and the increase of agricultural irrigation water has raised the groundwater level. The shortage of water resources and the irrational development and utilization have caused the crisis of water resources in my country to become more serious. [0003] Irrigation is a technical measure to supplement the water needed by crops. In order to ensure the normal growth of crops and obtain high and stable yields, crops must be supplied with s...
