What are the irrigation methods? What is the knowledge of irrigation methods?

Irrigation methods include border irrigation, furrow irrigation, flood irrigation, flood irrigation, micro-spraying and drip irrigation.

1, border irrigation is to build a ridge in the field and divide the field into many narrow plots, that is, border irrigation. Water is put into the border from the drainage ditch or capillary, and the water in the border moves forward as a thin layer of water and penetrates into the soil layer while flowing;

2. Ditch irrigation is to dig irrigation ditches between crops. After the irrigation water enters the irrigation ditch from the aqueduct or the capillary canal, it mainly permeates the soil from the bottom and wall of the ditch to the surrounding by soil capillary action during the flow.

3. Flooding irrigation, also known as grid irrigation, is to divide the irrigated land into many grid fields with ridges. During irrigation, the water layer in the field is kept to a certain depth, and the soil is wetted by gravity, which is mainly suitable for rice;

4. Flooding irrigation is a relatively extensive irrigation method. No furrow is opened in the field, and it overflows on the ground during irrigation and seeps into the soil by gravity. Irrigation uniformity is poor and water resources are wasted;

5. Micro-spraying, also known as fog drop sprinkler irrigation, is more water-saving than sprinkler irrigation. Because of the small droplets, its adaptability is greater than that of sprinkler irrigation, which is suitable for crops from seedling stage to growth and harvest stage. It is an advanced irrigation technology;

6. Drip irrigation is to use plastic pipes to send water to the roots of crops through orifices or drippers on capillaries with a diameter of about 10mm for local irrigation. It is the most effective water-saving irrigation method in arid and water-deficient areas at present, and the water utilization rate can reach 95%.
