温室专用水肥药一体化滴灌技术

Technique of Drip Irrigation Combined with Fertilizer and Pesticide in Greenhouse Appropriative

水肥药一体化技术是通过滴灌将可溶性固体肥料或液体肥料及土壤用药配兑而成的肥药液与灌溉水一起均匀准确地输送到作物有效根部土壤的一种灌溉方式。通过对目前设施农业生产中水肥药一体化技术与常规灌水施肥的分析和比较,总结了水肥药一体化技术既能保证蔬菜的营养品质,获得较高的产量,又有利于保持土壤肥力,有利于蔬菜生产的可持续发展的技术要点,以及省水、节约用肥、水肥药均匀使用、改善小区域生态环境、减少病害节约用药、提高品质、高效生产的实施效果。

The technique of drip irrigation combined with fertilizer and pesticide is a kind of irrigation method that let the fertilizer-pesticide liquid,which compound solubility solid fertilizer and liquid fertilizer and pesticide for soil,mixed with irrigation water,accurately and equably delivered to root segment soil by drip irrigation system.This essay analyzed and compared present technique of drip irrigation combined with fertilizer and pesticide and regular irrigation fertilization,summarized the technical essential that this technique can ensure the nutrient quality,obtain higher output,be in favor of keeping soil fertility,be in favor of the sustainable development for vegetable production,and summarized the implementation effects that the technique can save water and fertilizer,be in favor of equably using of water fertilizer pesticide,improve micro-region environment,decrease disease,save pesticide,improve quality,efficient production.
