| 摘 要： | 在日光温室膜下滴灌条件下,采用E20蒸发皿的水面蒸发量控制灌溉,研究了不同蒸发皿系数(Kcp=0.45,0.6,0.75,0.9)对初花期甜瓜生长、生理特性的影响. 结果表明:(1)水分处理对温室膜下滴灌甜瓜15 cm处地温产生了显著影响,其中T2(0.6) 与T3(0.75)处理的地温对甜瓜生长较为有利;(2)水分处理对甜瓜叶片扩展和叶面积大小影响较大,以2 d为灌溉周期,蒸发皿系数(Kcp)采用0.6有利于甜瓜叶片扩展,而且植株叶面积最大;(3)从甜瓜株高、茎粗/株高、总生物量与根冠比、叶片水分状况、叶片光合生理指标等综合分析,蒸发皿系数Kcp采用0.6(T2)都要优于其它水分处理.

| Abstract: | Based on the irrigation interval of 2 days,this study was conducted to evaluate the effects of different plant-pan coefficient(Kcp=0.45,0.60,0.75 and 0.90) on the growth and physiological characteristics of drip-irrigated muskmelon under film mulch in greenhouse.Irrigation quantities were determined by water surface evaporation(Epan) measured by a standard 0.2 m diameter pan.The results showed that:(1) The ground temperature(15 cm) of muskmelon was remarkably influenced by different water treatments.Among t... |
