The Study And Apply Of Needle-mode Saving Drip Irrigation Technology

There were a lot of disadvantages in traditional irrigation ways, like the abuse of water, high cost of irrigation, hard operation and servicing. So the needle-mode save drip irrigation technology were empoldered. It has a lot of advantages, like low cost, high efficiency, and easy operation and servicing. Good economic and society benefit were acquired, after used in some fruit, vegetable and fungus.1. The system of needle-mode saving drip irrigation technology was formed by liquid-store barrel, bracket, valve, conduit, liquid gobs, branch canal and imitate one-off transfusion implement. Small cell irrigation area was used in the system. Filter and a lot of conduit were abandoned. The conduit was currency. The cost was low. The back up of dripping caput was settled. The irrigation was exactitude and nicety.2. After using the system, soil physic and chemic character was improved, relative humidity was declined, microclimate was ameliorated, disease and pest were fall, nutrition absorb of vegetable was high. The vegetable grow well. The saving water rate was 12.1%,the colligate economic benefit was elevated 11.68%, in every growth season.3. The exactitude and nicety irrigation of the system was very satisfied for ecological sound organic soilless culture. The system can save water, labour force, and resource. It was also simple, easy to disassembly and build in. It was suit for every size using. For sparse fruit tree, it was the best select.4. Needle-mode saving drip irrigation technology was better than drip in and earth up in posterior edible fungus culture. Labor intensity was reduced. Mycelial injury flood and water lack were avoid. Nutrition and water accommodation were equality. The yield and production value was evaluated. The technology was mature in using.Needle-mode saving drip irrigation system evaluated the irrigation function, created well economic and society benefits. Its apply and...
