水肥气一体化在设施甜瓜栽培上的应用

Application of the Integration of Water,Fertilizer and Air on Melon Cultivation in Facilities

为了改善三亚设施甜瓜栽培过程中因根系环境缺氧造成甜瓜减产的现状,引进微纳米气泡发生器作为甜瓜灌溉用水的增氧装置。结合三亚现有以滴灌为主的水肥一体化栽培技术,设计了供水系统、过滤系统、施肥系统、管道系统、增氧系统装置,研发出了具体的增氧和肥水管理方案及其配套的设施甜瓜栽培技术,实现了三亚设施甜瓜水肥气一体化高效栽培,有效提高了甜瓜的产量和品质,实现667 m^2增收1612~2012元。

In order to improve the situation of decreased melon yield caused by the hypoxia of root environment in the process of melon cultivation in Sanya facilities,the micro-nano bubble generator was introduced as increasing oxygen device of melon irrigation water.The devices of water supply system,filtration system,fertilization system,pipeline system and increasing oxygen system were designed and specific schemes of increasing oxygen and fertilizer and water management,and the technology of supporting melon cultivation were developed by combning with the existing integration of water and fertilizer cultivation technology based on drip irrigation.Finally,the integration of water,fertilizer and air cultivation technology of Sanya melon in facilities was achieved and the yield and quality of melon increased effectively.The income incressed by 1612-2012 yuan per 667 m^2.
