通过对伊吾县淖毛湖镇晚熟哈密瓜[1~6]膜下滴灌栽培技术及病虫害防治的研究与应用,采用(1)滴灌系统首部设计选型:水源首部采用离心式过滤及网式过滤。施肥罐选择:根据面积大小选用,一般33.33 hm2应选100 L的施肥罐,机井用潜水泵,其流量与扬程均与滴灌系统设计流量和设计水头基本一致;(2)滴灌系统灌水量平均250 m3/667m2,全生育期滴水9次,节水率65.28%;(3)滴施追肥2~3次;(4)膜上行距40~50cm,株距45~50 cm,株数1000株/667m2,土地利用率提高25%~30%;(5)对主要病虫害进行了调查及农药筛选,提出了农药防治方法;经大面积示范推广取得显著效益。
Through the research and application of drip irrigation cultivation technology and pest and disease control of Late-maturing cantaloupe melon [1 ~ 6] in Zhimaohu Town, Yiwu County, the first design and selection of drip irrigation system was adopted: the first water source adopts centrifugal filtration and mesh filtration . Fertilizer tank selection: According to the size of the selection, the general 33.33 hm2 should be selected 100 L fertilizer tank, submersible pump wells, the flow and head are drip irrigation system design flow and design head is basically the same; (2) drip irrigation system average 250 m3 / 667m2, drip 9 times during the whole growth period, water saving rate 65.28%; (3) drip top dressing 2 to 3 times; (4) membrane spacing 40 ~ 50cm, plant spacing 45 ~ 50 cm, plant number 1000 / 667m2, (5) Investigation of major pests and diseases and screening of pesticides were put forward, and pesticide prevention and control methods were put forward. Significant benefits were obtained through large area demonstration and popularization.
