Problems solved by technology

[0004] 1. Using existing irrigation methods, the growth rate of plants is slow;
[0005] 2. Plants grown using existing irrigation methods have low medicinal value;
[0006] 3. Using the existing irrigation method, the transpiration of plants is greatly improved, and unnecessary water resources are wasted more due to transpiration
[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 high-calcium-brackish-water and fresh-water root-divided alternative irrigation method. The root-divided alternative irrigation method includes the step of salt isolating layer laying, wherein a salt isolating layer comprises a rubble layer, a fine bamboo spar layer, a fine stone layer and a mixed soil layer. The salt isolating layer is laid in a planting region, and the distance between the upper surface of the salt isolating layer and the ground surface is 80 cm to 100 cm, the rubble layer is prepared from zeolite, ceramsite and grait, the fine stone layer is prepared from phosphate rock powder, fermented saw dust and wheat bran, and the mixed soil layer is prepared from Kanuma soil and humus. The invention further provides an application of the high-calcium-brackish-water and fresh-water root-divided alternative irrigation method to planting of cedars in saline and alkaline land. By means of the root-divided alternative irrigation method, the growing speed of plants is increased, the medical value of plants is increased, and the unnecessary transpiration of plants is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of irrigation, and in particular relates to a root-split alternate irrigation method using high-calcium brackish water and fresh water and its application in planting cedar in saline-alkali land. Background technique [0002] Brackish water refers to water whose alkalinity is greater than hardness, contains a large amount of neutral salt, and has a pH value greater than 7. my country's brackish water is mainly distributed in the northern and eastern coastal areas. [0003] At present, the shortage of water resources has become a worldwide problem, and China's water resources are seriously short, and regional and seasonal water shortages are also a major feature of China's water resources. With the continuous and rapid development of the economy and society and the sharp increase in water demand, the shortage of fresh water resources has become an important limiting factor for the development of industry and...
