Description

Technical Field

[0001] The invention relates to the technical field of soil moisture conservation, in particular to a microporous infiltration irrigation moisture conservation and water-saving device and an application system thereof. Background Art

[0002] Drip irrigation uses plastic pipes to deliver water to the roots of crops through orifices or drippers on a capillary tube with a diameter of about 10 mm for local irrigation. It is the most effective water-saving irrigation method in arid and water-scarce areas, and the water utilization rate can reach 95%. Drip irrigation has a higher water-saving and yield-increasing effect than sprinkler irrigation, and can be combined with fertilization to increase fertilizer efficiency by more than double. It can be used for irrigation of fruit trees, vegetables, cash crops and greenhouses, and can also be used for irrigation of field crops in arid and water-scarce areas. Its disadvantage is that the dripper is prone to scaling and clogging, so the water source should be strictly filtered. Moisture conservation refers to maintaining the humidity in the soil suitable for seed germination and crop growth. Keep the water from evaporating and leaking. For example, the land should be compacted after sowing to reduce the pores and allow the upper dense soil to retain the moisture in the lower soil.

[0003] At present, when farmers perform drip irrigation on fruit trees, they lay the drip tube on one side of the fruit tree. The drip tube is controlled by a valve and can only control the closing and opening of the water volume, but cannot control the amount of water. It is easy to water the fruit trees with too much water, which affects the growth of the fruit trees. When mixing drugs with water, most of the time, the drugs are placed inside the water tank for mixing. After drip irrigation, the drugs are easy to remain inside the water tank, which causes the problem of excessive addition of drugs to crops. Summary of the invention
