Repairing the water supply channel Repairing the water supply channel, reducing leakage and ensuring smooth flow, generally saves water by 20% to 30%. If a cylindrical plastic water supply bag is used as a canal, the water utilization rate can reach over 95%.
The whole land is made of small cockroaches, short sputum, narrow sputum, fast water flow, saving time and less water. According to local experience, the canal irrigation area is generally 50 meters long and 3 meters wide. The well channel area is suitable for 25 meters long and 2 meters wide. Spring and white fields are very important for water-saving irrigation.
The three kinds of fields are rich in water, wide ridges and narrow, and the ground is flat. You can take the method of pouring water with two waters. For the land with one head and one low, you can take the method of building high water channels and send the water first. Go to the top of the terrain and let the water flow down the terrain. Where the water source is relatively scarce, it can be carried out by means of spot-casting and then watering. This pouring method is suitable for crops such as cotton on-demand and sweet potato transplanting, and generally saves 80% to 90% of irrigation.
According to the measurement and test, the scorpion is about 50 meters long. When the water is poured to 70%-80%, it can be changed to another one. About 20%.
In order to reduce the leakage of channels and speed up the flow of water, in order to reduce the leakage of the channels and to increase the speed of the water flow, it is possible to adopt a method of collecting the water from one group to concentrate the water supply in one channel to expand the scope of the watering and improve the irrigation efficiency.
The sprinkler irrigation effect has the good effect of uniform irrigation and water conservation and soil conservation. It can not only save a lot of water, but also improve the irrigation quality. It can be used in both plain and mountainous areas. Generally, it can save about 50% of water by channel water supply method. Promotion.
