The trickle watering is an irrigation method that evenly and slowly drips the water and nutrients needed by crops into the soil in the root zone drop by drop according to crops' water requirements through the pipe system and the emitter equipped in the capillary pipe. The trickle watering system has the following advantages:
1. Increase output and improve product quality
Compared with the ground irrigation: Production increase of 20 to 30%; The melons and fruits come to market one week in advance; Fruit trees bear fruits one year in advance; The length of cotton fiber and the micronaire value both increase; The refractive sugar of melon and fruit increases by 1-2 times, and the vitamin content also increases.
2. Save water, energy, fertilizer and labor
Water saving: 50% water saving compared with the ground irrigation for cotton, 50-70% water saving compared with drip irrigation for vegetable, 70% water saving for melon, and 15-20% water saving compared with the sprinkling irrigation;
Energy saving: The trickle irrigation uses a very high rate of water, reducing the pumping time, thereby reducing energy consumption;
Fertilizer saving: Compared with the furrow irrigation, the average fertilizer saving is 47.5%; And the average fertilizer saving is 53.3% compared to the drip irrigation under mulch.
Labor saving: Save about 50% of labor services (excluding flower picking).
3. Excellent adaptability
The trickle irrigation adopts material plastic pipes to conduct water delivery. The pipes are light, simple in structure and easy to set up, which can adapt to all kinds of complicated terrain; The various drippers which have different flow rate of the trickle irrigation can meet the needs of irrigation under different soil conditions. The trickle irrigation can adapt to different complicated terrain, mountainous and sloping land (for barren mountain greening, railway greening and desert greening); The trickle irrigation is suitable for saline-alkali land, and then the saline-alkali land can be improved into a good land suitable for crop growth by using the trickle irrigation for 1-2 years.
4. Easy to realize automatic control
The trickle watering system marks the trend in traditional agriculture towards pipelining and pressurized water delivery, laying the foundation for the realization of automation. Automation can save labor, and at the same time control the irrigation more effectively, so as to achieve agricultural intensification, informatization and scale operation.
5. It does not affect other agricultural activities
Because the trickle irrigation system belongs to the local irrigation, space between crops is kept dry, and people and machinery can enter the field at any time to fork, shoot, spray, harvest and do other agricultural activities, which improves the efficiency of field management.
