| 摘 要： | 采用Φ20标准蒸发皿的水面蒸发量为控制灌溉参数,研究不同灌水方式(覆膜滴灌、覆膜沟灌和覆膜小畦田灌)对温室环境和番茄生长和灌溉水利用系数的影响。试验结果表明:在秋冬茬口的日光温室内,与膜下沟灌和传统覆膜畦田灌溉比较,覆膜滴灌一定程度降低了温室湿度,保持了土壤水分一直处于较高的水势范围,使番茄产量和灌溉水利用效率达到最高。另外,采用覆膜滴灌时,灌水周期为3d,蒸发皿系数取1.0时,产量和灌溉水利用效率最高,推荐作为该茬口的灌溉制度技术指标。

Experiment on Different Irrigation Methods of Tomato in Solar Greenhouse |
| |
| Abstract: | Based on the irrigation amount of water surface evaporation of a standard 0 .2 m diameter pan ,this study was conducted to evaluate the effects of different irrigation methods (mulched drip irrigation ,mulched furrow irrigation and mulched border irrigation ) on the growth and irrigation water use efficiency of tomato and indoor environment in solar greenhouse in 2013 and 2014 .Compared to furrow irrigation and traditional border irrigation under plastic film ,irrigation water use efficiency and yields of tomato were the highest under mulched drip irrigation because of the reduced indoor humidity and the increased soil matric potential in the greenhouse in autumn and winter .In addition ,from the view point of the highest yields and irrigation water use efficiency ,the pan coefficient of 1 .0 and the irrigation interval of 3 days should be suggested as the guideline to drip irrigate tomato in solar greenhouse . |
