| 摘 要： | 将微润灌溉技术应用于大棚种植试验中,设置了5种不同的处理来探究微润灌溉条件下微润管埋深与压力水头对小葱株高、产量以及土壤水分分布的影响。其中,常规浇灌作为对照,当做一组处理。结果表明:在小葱生长期内,各处理日均用水量和株高都随生育期的进行先增大后减小;微润管埋深对土壤水分分布影响较大,而压力水头对水分分布影响较小;微润管的埋深和压力水头对小葱生长、产量有较大的影响,且埋深比水头对小葱生长状况的影响更为明显;微润管埋深为4 cm的处理在长势与产量方面优于埋深为7 cm的;微润灌溉条件下,小葱的长势与产量较优于常规浇灌;微润灌溉较常规浇灌略微节水。

| Abstract: | Moistube-irrigation technology was applied in a greenhouse cultivation experiment.And five different treatments were set up to explore the effects of buried depth and pressure head of moistube-pipe on the growth and yield of onion and soil moisture.The conventional irrigation was set as the control treatment.The results show that during the onion growth period, the average daily water consumption and plant height increase first and then decrease;buried depth has great influence on soil water distribution, however, pressure head has little impact;buried depth and pressure head has a significant impact on the growth and yield of onion;and the effect of buried depth is more obvious;in terms of plant height and yield, the buried depth of 4 cm is superior to the buried depth of 7 cm.The growth and yield with moistube-irrigation are better than that of the conventional irrigation.Compared with the conventional irrigation, moistube-irrigation can save water. |
