44444444444444444444444444444444444444444Greenhouses simple greenhouse greenhouse vegetables water drip drip irrigation technology is the most ideal technology, it has a water-saving and increase production, cooling, save work, high efficiency advantages.
A, simple drip irrigation production:
First built in the shed capacity of 3 cubic meters - 5 cubic meters, height 1 meter to 3 meters of reservoirs,baidu the pool of water outlet pipe opening gate and water meter installation, with 38 mm plastic pipe as heat pipe, MAO and pools of water outlet pipe. Branch to the layout of the capillary and form has two kinds:
1. Along the capillary length setting. In the tent with 25 mm plastic drip irrigation branch pipe and PE pipe do vertical capillary connection, and install valve in the manifold; In huts with MAO GuanPing line, perpendicular to pipe, each 1 m distance installation 1 the pipe diameter is 15 ~ 20 mm, long length and the canopy equivalent plastic pipe, pipe wall with a hole on distance is 35 cm, diameter 1.0 1.3 mm of plastic capillary tubes, easy of drip irrigation network system, on the capillary with mulching film, film actually grow vegetables. Is easy to operate, the advantages of this arrangement is good for management.
2. Along the shelf layout capillary. With several root length is shed four times across the porous plastic capillary, head end connected to the tent of lateral branch and parallel tent
3, cross is bent pipe with plastic mulching and film actually grow vegetables. The advantages of this arrangement is relative vegetables with plenty of sunshine, is advantageous to the growth and development.
Second, simple and drip irrigation application advantages in greenhouse vegetables
1. The benefit is remarkable. Drip irrigation can timely, right amount ground root zone water supply for fat to vegetables, to make vegetables root soil to keep appropriate moisture, oxygen and nutrients. Using drip irrigation of greenhouse vegetables per 1, 667 square meters net income than flooding DaPengCai increase 45%.
2. To save water. According to the test, simple drip irrigation water utilization rate reached 95% ~ 98%, baidu than irrigation water saving 45%, than the ground irrigation saving water by 60%.
3. The cost is cheap. Simple drip every 667 square meters with investment 667 yuan, is a third of the vegetable micro spray technology investment.
4. Improve the canopy temperature. Simple greenhouse using drip irrigation than improving canopy temperature 5 (C or so, bring vegetables listed about half a month earlier.
5. Reduce morbidity. Simple water capillary under mulch drip irrigation, can effectively suppress vegetable mould and black rot.
6. In addition to the wall easily. Simple drip capillary on the surface of the earth, blocking problem easy to find, local processing hole plug also can again any time.
7. Save fertilizer. Greenhouse vegetables all the topdressing fertilizer into the pool with water droplets to crop rhizosphere soil, avoid the loss of fertilizer, leakage and volatilization.
