| 摘 要： | 用温室小区试验的方法,通过对番茄株高和茎粗、果实品质和产量以及水分生产效率进行比较,探讨了温室栽培茄果类地下滴灌灌水控制下限的适宜取值范围。结果表明:在壤质土壤的试验地上,当地下滴灌管埋深为30 cm、计划湿润层深为15 cm~45 cm(厚度30 cm)、湿润比取0.7、灌水控制上限取田间持水量时,将土壤水吸力30 kPa作为控制灌水的下限,有利于番茄植株生长发育,可以达到高产、优质、节水的目的。

| Abstract: | Plot experiment was carried out to determine the suitable numeric range of low irrigation limit under subsurface drip irrigation in greenhouse, by comparing the plant height, stem diameter, fruit quality, yield and water use efficiency of tomato under different treatments. The results indicated that when the drip tuLes were buried at 30cm underground, the depth of designed moistening layer of soil was 15 cm-45 cm and the watted ratio was 0.7, and the upper irrigation limit was field capacity on loam soil while the low irrigation limit was 30 kPa in soil water suction, the growth of tomato was good, and the objectives of high-yield, high quality and water-saving could be achieved. |
