摘要 为了探寻番茄地下滴灌合理的灌溉计划拟定方法,进行了田间试验,试验布置了-10cm(D1)、-20cm(D2)、-30cm(D3)、-40cm(D4)、-50cm(D5)五个毛管埋设深度,研究了同一土壤基质势控制条件下番茄根系的分布范围及土壤水分的变化规律。结果显示,可以将负压计埋设于滴头横向距离0cm附近、20cm深度处,监测番茄根系层土壤水分状况,制定灌溉计划。 In order to find a reasonable way to schedule subsurface drip irrigation for tomatoes ,an experiment was carried out to stud‐y soil moisture conditions at the same soil matric potential variation .The tests arranged -10 cm (D1) , -20 cm (D2) , -30 cm (D3) ,-40 cm (D4) ,-50 cm (D5) five drip tape buried deep .The results showed that ,tensiometers could be installed in the soil which was near dripper in horizontal and 20 cm depth .
