Save water, fertilizer and labor
Drip irrigation is a total pipeline and partial micro irrigation, which minimizes water leakage and loss.At the same time, because of the timely supply of water for the root area of crops, there is no problem of peripheral water loss, and the water utilization efficiency is greatly improved.Irrigation can be easily combined with fertilization, i.e., dissolve the fertilizer after infusion into the irrigation system, due to chemical fertilizer combined with irrigation water, fertilizer nutrients evenly applied directly to the crop root layer, realize the synchronous water, greatly improving the effective utilization rate of fertilizers, at the same time as a small local control, micro irrigation, water leakage is less, so can save find.The application of irrigation and fertilization technology provides convenience for the timely supplement of expensive micronutrients to crops and avoids waste.Drip irrigation system is only controlled manually or automatically by the valve and combined with fertilization, so it can significantly save labor input, reduce production cost, improve resource utilization and ensure full coverage of irrigation.
Control temperature and humidity
The large amount of water in a conventional furrow irrigation is large, and the ground surface stays wet for a long time. Not only does the temperature of the canopy and ground decline too fast, but also the temperature of the ground rises slowly, and the evaporation capacity increases. The high indoor humidity will easily lead to the occurrence of diseases and insect pests of vegetables or flowers.Because drip irrigation is local micro-irrigation, most soil surface remains dry, and the drip head supplies water to root soil layer evenly and slowly, which has obvious effects on maintaining and recovering ground temperature, reducing water evaporation and reducing indoor humidity.Using submembrane drip irrigation, that is, placing the drip irrigation pipe (belt) under the film, the effect is better.In addition, due to the convenient operation, drip irrigation can be carried out at high frequency, with small outflow holes and slow flow rate. Each irrigation time is relatively long, and the soil moisture variation range is small. Therefore, the soil in the root area can be controlled to keep close to the humidity that is most suitable for the growth of vegetables, flowers and other plants for a long time.As indoor air humidity and soil moisture are controlled, the occurrence of diseases and insect pests can be significantly reduced, and the use of pesticides can be reduced.
Maintaining soil texture
Under the action of large irrigation amount of traditional furrow border irrigation, the soil of the facility is subjected to more erosion, compaction and erosion. If the soil is not tilled in time, serious compaction and poor ventilation will be caused and the soil structure will be damaged to some extent.Drip irrigation is a micro irrigation, and the water slowly and evenly infiltrates into the soil, which can maintain the soil structure and form a suitable soil water, fertilizer and thermal environment.
Improve quality, increase production and efficiency
The application of drip irrigation can reduce the application amount of water fertilizer, pesticide and the occurrence of diseases and pests, which can obviously improve the product quality.In conclusion, compared with traditional irrigation methods, drip irrigation in greenhouse or greenhouse and other facilities in horticulture can greatly improve product yield, bring it to market earlier and reduce the cost input of water fertilizer, pesticide application and labor, so the economic and social benefits are significant.The drip irrigation technology of facility gardening is adapted to the requirements of high yield, high efficiency and high quality modern agriculture, which is the fundamental reason why it can exist and be widely used.
