摘要
采用温室小区作物栽培的试验方法寻求温室萝卜适宜的灌水控制指标,通过对全生育期土壤水分下限的控制,研究了不同灌水条件下日光温室萝卜产量、产量分配及水分利用效率。研究发现,水分过高或过低都不利于萝卜增产,同时也不利于水分利用效率的提高,水分适宜(RT70处理)不仅可以提高萝卜的产量,而且可以提高水分利用效率和灌溉水利用效率。本研究对温室萝卜节水灌溉的进一步研究具有重要的科学指导意义。
In order to seek for suitable irrigation control index for radish in sunlight greenhouse, a field plot experiment was conducted in greenhouse in this paper. By controlling the lower limits of soil moisture in the whole growing season, radish yield, yield distribution and water use efficiency in greenhouse were studied under different irrigation treatment. The result showed that neither too high nor too low soil moisture was favorable to increase yield and water use efficiency of radish. While suitable soil moisture （RT70 treatment） can not only increase radish yield, but also increase water use efficiency and irrigation use efficiency. The research provided important scientific guide for further research of water-saving irrigation on radish in sunlight greenhouse.
