摘　　要：就一种新型的防堵渗灌系统对黄瓜、番茄、辣椒、豇豆及青菜的产量、生产成本等要素以及土壤理化性质的影响进行研究。结果表明,使用新型渗灌技术后,可减少用工25%~60%;黄瓜、番茄、辣椒、豇豆、青菜分别增产14.5%,16.1%,22.4%,13.8%和9.6%;土壤中的活菌总数是对照5.6倍,pH值比对照下降了0.19;提高了土壤中水解性N、速效P、速效K及有机质含量。Effects of a new type anti-blocking subsurface irrigation technique on the output and production cost of cucumber,tomato,pepper,cowpea and pak-choi,as well as the soil properties were studied.The results showed that by using this technique,the outputs of cucumber,tomato,pepper,cowpea and pak-choi increased by 14.5%,16.1%,22.4%,13.8% and 9.6%,respectively.The labor cost decreased by 25%~60% and total soil viable organisms were 5.6 times as much as the control with pH value dropped by 0.19.In addition,the organic matter,hydrolyzed nitrogen,quick-acting phosphorus and potassium were improved distinctly.
