摘　　要：为推广应用肥水一体化技术,针对辣椒早春大棚生产,开展了减量施肥对辣椒产量影响的试验。在测定试验点的土壤养分本底指标基础上,根据辣椒需肥规律和各生育期所需N、P、K的用量和所占比例,设计不同专用肥,采用膜下滴灌方式进行追肥,以传统漫灌施肥方法为对照。试验结果表明,通过肥水一体化技术,可比传统漫灌施肥量减少51.79%,比传统漫灌节水85.42%,每667 m2可节约生产成本约868元。达到了辣椒早春大棚“一控两减”的生产目的,节本增效效果显著。In order to promote the application of the integrative water and fertilizer technology,effects of fertilizer reduction on the yield of pepper planted in greenhouse were measured in early spring.The original contents of nutrients in soil were measrued at each site.Specialized fertilizers were designed according to the fertilizer demanding law of pepper and the amount and proportion of N,P and K required at each growth stage.The fertilizers were applied by drip irrigation under the mulch,taking the traditional flood-irrigation fertilization as control.The results showed that the integrative water and fertilizer technology reduced the applicaiton of fertilizers up to 51.79%,and save the applicaiton of water up to 85.42%compared with the conventional irrigation method.Thus,the production cost could be saved by about 868 yuan/667m2.Taking together,application of the integrative water and fertilizer technology achieved the goal of"one control and two reductions"for pepper production in greenhouse in early spring,and the effects of reducing cost and increasing efficiency were remarkable.
