摘要
通过温室膜下滴灌实验,研究不同灌水量对日光温室番茄耗水规律的影响.结果表明:番茄整个生育期耗水量随着灌水量增加而增加,各处理耗水量均表现为结果盛期>结果前期>结果后期>营养生长期;番茄整个生育期耗水强度随着灌水量增加而增加,各处理耗水强度均表现为结果盛期>营养生长期>结果前期>结果后期.在滴灌条件下,作物耗水量为448 mm时番茄产量最高,可达9 151 kg/666.7 m2.
The experiment was carried on drip irrigation under film in solar greenhouse to study irrigation amount of tomato and it＇s water consumption. The results showed that： the water consumption of tomato rate in whole growth duration was increased with irrigation amount increased, the water consumption of each treatment ranked： peak fruit stage~ begin fruit stage〉later fruit stage 〉 vegetative growth stage. The intensity of the whole growth duration of tomato consumption was increased according irrigation increase and water consumption intensities ranked： peak fruit stage〉 vegetative growth stage〉 begin fruit stage〉 later fruit stage. In the experiment at drip irrigation under film, tomato water consumption amount of 448mm could be achieved highest tomato yield of 9 151 kg/666.7m^2.
