The technical points of the drip irrigation zone
1. Water saving, fertilizer saving, labor saving
Drip irrigation belongs to the whole pipeline and local micro irrigation, which reduces the water leakage and loss to the minimum. At the same time, because of the ability to supply water in the root area of crops in a timely manner, there is no loss of peripheral water, and the efficiency of water utilization is greatly improved. Irrigation can be conveniently combined with fertilization, fertilizer is dissolved after injecting the fertilizer with irrigation systems, irrigation water together, nutrients directly and uniformly applied to the crop root layer, realize and synchronization, greatly improving the effective utilization rate of fertilizer, and also because is a small range of local control, micro irrigation, water and fertilizer leakage is less, thus saving the consumption of chemical fertilizers. The use of irrigation and fertilization technology provides convenience for the timely supplement of expensive trace elements and avoids waste. Drip irrigation system is manually or automatically controlled by the valve, combined with fertilizer application, so it can save labor input, reduce production costs, improve resource utilization and ensure full coverage irrigation.
Two. Control of temperature and humidity
The traditional furrow irrigation in greenhouse, a large amount of irrigation, moist surface temperature, long time, not only shed temperature drops too quickly, a slower recovery, and evaporation increased, the indoor humidity is too high, easily lead to diseases and insect pests of vegetables or flowers. Drip irrigation is a partial micro irrigation. Most of the soil surface is dry, and the dripping head is evenly and slowly supplying water to the root and soil layer. It has obvious effect on maintaining and recovering the ground temperature, reducing water evaporation and reducing indoor humidity. The use of drip irrigation under film, that is, the drip irrigation tube (belt) is arranged under the film, the effect is better. In addition the drip irrigation convenient operation, can implement high frequency irrigation, and the hole is very small, slow flow rate, each irrigation time is relatively long, the change of soil moisture was small, it can control the root zone in the soil can be maintained for a long time in close proximity to the most suitable for vegetables and flowers growing humidity. The control of indoor air humidity and soil moisture can significantly reduce the occurrence of pests and diseases, and then reduce the amount of pesticides.
Three. Keep the soil structure
In the traditional furrow irrigation large irrigation amount under the soil more erosion, compaction and erosion, if not timely Ripper will lead to serious compaction, ventilation, decreased to a certain extent by soil structure. Drip irrigation is a kind of micro irrigation. The water infiltration slowly and evenly into the soil can maintain the soil structure and form suitable soil water, fertilizer and thermal environment.
Four, improve quality, increase production and increase efficiency
As the application of drip irrigation reduces the amount of water and fertilizer, the application of pesticides and the occurrence of diseases and insect pests, the quality of the products can be improved obviously. In conclusion, compared with traditional irrigation methods, drip irrigation with horticultural facilities such as greenhouses or greenhouses can greatly increase the output of products, advance the time to market, and reduce the cost of water and fertilizer, pesticide application and labor, so that the economic and social benefits are significant. Drip irrigation technology in protected horticulture is adapted to the requirement of modern agriculture with high yield, high efficiency and high quality. This is also the fundamental reason for its existence and promotion.
