| 摘 要： | 采用日光温室栽培番茄的试验方法,就节点式渗灌、沟灌、滴灌、普通渗灌等4种不同的灌溉方法对土壤温度的影响进行了研究.试验结果表明,灌溉方法对土壤10 cm深处土壤温度影响不显著;沟灌与节点式渗灌、滴灌和普通渗灌处理20～50 cm土层土壤温度差异达到5%显著水平,在4种灌溉方法中,番茄全生育期0～50cm土层土壤的总积温为滴灌最高,达为6 205.4℃,比节点式渗灌,普通渗灌、沟灌分别高了10.2℃、52.9℃和118.7℃.灌水方法对土壤温度日变化的影响为:10 cm深土层土壤温度最大值节点式渗灌和普通渗灌的分别出现在13:00时和14:00时左右,滴灌在15:00时前后,沟灌出现在16:00时左右.

| Abstract: | A field plot experiment of tomato is conducted in the greenhouse to study the effect of four irrigation methods,namely drip filtration irrigation,furrow irrigation,drip irrigation and filtration irrigation,on soil temperature.Results show that the temperature in the soil layer of 10 cm depth is not significantly affected by different irrigation methods.The soil temperatures between filtration irrigation and other three irrigation methods in the soil layer of 20~50 cm depth are significantly different at 5% ... |
