Water-saving drip irrigation technology for potato planting

Abstract

The invention discloses a water-saving drip irrigation technology for potato planting. The technology comprises a planting greenhouse, wherein a water collecting trough is formed on the periphery of the top of the planting greenhouse, a first water delivery pipe is arranged at the bottom of the water collecting trough and inserted into a water collecting pool, a water supplementing pipe is arranged on the side surface of the water collecting pool, a first water pump is arranged on the water supplementing pipe, the other side of the water collecting pool is connected with one side of a water purification box through a second water delivery pipe, a primary filter and a second water pump are sequentially arranged on the second water delivery pipe in the water flow direction, a third water delivery pipe is arranged on the other side of the water purification box and extends into the planting greenhouse, and a third water pump and a first electromagnetic valve are sequentially arranged on the third water delivery pipe in the water flow direction. By means of the water collecting trough, a soil moisture sensor, a first electromagnetic valve, a second electromagnetic valve and a central controller, the water-saving drip irrigation technology for potato planting has good water-saving performance and high degree of automation and is more convenient to use.

Description

technical field [0001] The invention relates to the technical field of drip irrigation, in particular to a water-saving drip irrigation technology for potato planting. Background technique [0002] China's existing water-saving irrigation methods include channel anti-seepage, sprinkler irrigation, micro-sprinkler irrigation, seepage irrigation and drip irrigation. Drip irrigation uses plastic pipes to send water to the roots of crops through holes or drippers with a diameter of about 10mm. , it is currently the most effective water-saving irrigation method in arid and water-scarce areas. The water utilization rate can reach 95%. Compared with sprinkler irrigation, drip irrigation has a higher water-saving and production-increasing effect. At the same time, it can be combined with fertilization to increase fertilizer efficiency by more than double It is suitable for irrigation of fruit trees, vegetables, commercial crops and greenhouses, and it can also be used for irrigation...
