河西走廊灌区早春拱棚西瓜平作膜下滴灌水肥一体化高效栽培

早春拱棚栽培是河西走廊灌区西瓜生产的主要形式,通过开展西瓜平作膜下滴灌水肥一体化栽培技术示范研究,从品种选择、栽培技术管理、病虫害防治等方面对西瓜平作膜下滴灌水肥一体化栽培技术进行总结。相较于垄膜沟灌栽培,667 m^2可节水56.5%,节肥48.1%,省药10%~20%,为促进西瓜特色产业发展提供技术支撑。

High Efficiency Cultivation of Early Spring Watermelon with Water and Fertilizer Integration under Mulch in the Irrigation Area of Hexi Corridor

Abstract: Early spring tunnel cultivation is the main form of watermelon production in the irrigation area of Hexi corridor. Through the development of demonstration research on watermelon culture film with drip irrigation, technologies were summarized from the aspects of cultivar selection, planting technology management, plant diseases, pests prevention and control and so on. Compared with ridge film furrow cultivation, this cultivation form could save water 56.5%, fertilizer 48.1%, pesticides 10%-20% per 667 m2 and provide technical support to promote the development of the watermelon characteristic industry.
