Water-saving and labor-saving greenhouse water and fertilizer integrated micro-spray can also be used for irrigation in the field. In the Zhaojiaying Town of Shunyi, the suburb of Beijing, 600 acres of wheat fields in the wheat demonstration area of ​​Beiying Village are being rushed to pour frozen water. Unlike the dismantling sprinklers of other plots, the automatic spray micro-injection equipment is used here, and remote control is also possible. Mobile phone control.

This is the first demonstration zone for automatic control of wheat micro-spraying water and fertilizer integrated fertilizer in Beijing. Unlike conventional manner irrigation sprinkler or removed, instead of using the micro jet with automatic control Fertigation through a valve and a solenoid valve control system automatically switches per Ejecta pulley irrigation and fertigation system by micro jet with containing a mixture of water and fertilizer at different growth stages of crops needed, timely and appropriate transported to the field, so that field crops and greenhouse crops also a kind, enjoy the precision agriculture technology "service."

Another set of equipment in the demonstration area is called the hour hand sprinkler. It combines the hour hand sprinkler and the fertilizer injection system to deliver the corresponding water and fertilizer mixture to the field according to the growth period of the crop to realize the integration of water and fertilizer. The hour- needle sprinkler irrigation can be applied to field crops such as wheat, corn, and potatoes. Compared with the existing demolition sprinkler irrigation, it can reduce the labor consumption by 50 %. One person can manage 8 to 12 hour-hour sprinklers covering 4000. To 6,000 acres of land.

According to estimates, compared with conventional irrigation, the two irrigation methods can achieve water saving of 50 cubic meters per mu in the water and fertilizer integration demonstration area , and increase the yield of wheat by more than 50 kg, while saving labor. It is estimated that using this irrigation method, the average income per mu can be increased by about 200 yuan.
