Quanrun Plastics: Application of Drip Irrigation in Vegetable Planting
Drip irrigation, as a water-saving and fertilizing tool that saves labor, labor, and irrigation evenly in vegetable production, has been recognized, understood, and recognized by vegetable producers in vegetable development in recent years, and some of them have been used.
As an advanced agricultural production technology, drip irrigation is relatively slow. The main reason is that drip irrigation is restricted by quality and price. Currently, drip irrigation and drip irrigation pipes are commonly used in the market, and drip irrigation belts have lower prices. In various forms, there are micro-holes directly drilled in the drip irrigation, embedded type, a labyrinth; but its quality is relatively poor, short life, easy to plug, the length of the laying should not be too long, Otherwise, the uniformity of the drip will be greatly affected. The price of drip irrigation pipes is 3-4 times higher than the price of drip irrigation belts. The most commonly used on the market is the use of drip irrigation pipes with embedded labyrinth drippers. The wall thickness of drip irrigation pipes is generally between 0.6 and 1.2 mm (and Drip tape wall thickness is only 0.15 ~ 0.3mm). The service life of the drip irrigation pipe is very long. Because the pipe wall is made of PE material, the temperature and light do not pose a threat to the basic structure; the anti-clogging ability is very strong, and the drip irrigation pipe within 100m within a single drip irrigation pipe is evenly distributed and can be laid 20cm below the surface. Affects dripping speed and uniformity.
Double-hole micro-drip irrigation belt, the drip irrigation belt with even water, strong anti-blocking ability, but the laying length should not be too long, more suitable for greenhouse or about 30 meters in length of greenhouse use.
