加工番茄膜下滴灌技术研究与示范

通过对宁夏惠农区加工番茄膜下滴灌与沟灌的灌水量、产量、管理费用和水分利用效率等进行研究,结果表明:采用膜下滴灌技术具有明显的节水、增产、省工等效果,与沟灌技术相比节约用水达67%;采用膜下滴灌比沟灌增产30%;试验条件下,采用膜下滴灌比沟灌的水分生产率提高301%～333%;采用膜下滴灌加工番茄可以节约(降低)生产成本60%.研究表明在宁夏银北灌区大面积推广膜下滴灌技术具有可行性.

Research and demonstration on processing tomato drip irrigation under the membrane technique

The experiment was conducted in two different irrigation patterns （drip irrigation under membranes and furrow irrigation）. The result indicated： Uses under the membrane the drip irrigation technology to have obvious effects and so on saving water, production increase, labor saving, infuse a technique with slot to compare a save to reach to 67% with water; Uses under the membrane the drip irrigation to fill compared to furrow irrigation production 30% Test a condition down, adopt under the membrane drip irrigation,water use efficiency raise 301%-333% than furrow irrigation; Uses under the membrane drip irrigation processing tomato is possible to reduce the production cost 60%. The results showed under the membrane drip irrigation is feasibility in the north of Ningxia big area generalize.
