摘　　要：采用日光温室小区栽培试验的方法,通过对番茄株高和茎粗、产量、果实品质等指标进行比较,探讨了温室栽培茄果的节点渗灌灌水控制上限适宜取值范围。结果表明:在土壤质地中等的试验地上,当节点渗灌管埋深30 cm、计划湿润层厚度30 cm、湿润比取0.5、灌水控制下限取土壤水吸力30 kPa时,将土壤水吸力12 kPa作为灌水控制上限,有利于番茄植株生长发育,可以达到较高产、优质、节水的目的。Adopt test method of field-planting potatoes in sunshine greenhouse. Through comparison of plant height, stem diameter, yield, and quality of fruits and etc, explore proper upper limit of node permeation irrigation for solanberryplanting in greenhouse. The results indicated that when the conditions of that soil quality is average, node permeation irrigation pipe was 30cm deep, planned moist layer was 30 cm thick, moist ration was 0. 5, lower limit control of subsurface irrigation was 30 kPa for soil water suction, upper limit control of subsurface irrigation was 12 kPa, it will be beneficial to the growth of potatoes, and attain the objectives of high production, top quality and water-saving.
