Water-saving irrigation device suitable for shallow root crops

Abstract

The invention discloses a water-saving irrigation device suitable for shallow root crops, and belongs to the technical field of agricultural irrigation. The water-saving irrigation device comprises aplurality of irrigation water tanks which are evenly distributed in a linear mode and a water supply pipe, and a connecting rod is fixedly connected between every two adjacent irrigation water tanks.;the two ends of the connecting rods are fixedly connected with the irrigation water tanks on the two sides correspondingly, and water injection pipes are arranged at the top ends of the irrigation water tanks in a communicating mode. Targeted irrigation can be carried out by combining root system distribution characteristics of shallow root crops, main centralized irrigation is carried out on shallow soil where more root systems are distributed, secondary proper irrigation is carried out on deep soil where less root systems are distributed, and irrigation is carried out in a mode of directlyinfiltrating water into the soil, evaporation of water in the irrigation process is greatly reduced, then water resources are saved, a small amount of fertilizer can be automatically applied to the crops in the irrigation process, and better growth of the crops is facilitated.

Description

technical field [0001] The invention relates to the technical field of agricultural irrigation, in particular to a water-saving irrigation device suitable for shallow root crops. Background technique [0002] In the process of agricultural planting, in order to ensure the normal growth of crops and obtain high and stable yields, crops must be supplied with sufficient water. Under natural conditions, often due to insufficient precipitation or uneven distribution, the water requirements of crops cannot be met. Therefore, artificial irrigation is sometimes required to make up for the lack of natural rainfall. The principle of irrigation is that the amount of irrigation, the frequency of irrigation and the time should be determined according to the water demand characteristics of medicinal plants, growth stages, climate, and soil conditions, and should be timely, appropriate, and rational irrigation. [0003] The root distribution characteristics of shallow-rooted crops are: a ...

AI Technical Summary

Problems solved by technology

[0003] The root distribution characteristics of shallow-rooted crops are: a large number of main roots are distributed in shallow soil, and only a few roots are distributed in deeper soil. In the prior art, when shallow-rooted crops are irrigated, the distribution of their roots is not combined. Characteristics of targeted irrigation, a lot of water resources are often wasted in the irrigation process, which is not conducive to energy saving and environmental protection
