痕量灌溉是基于土壤毛细管力原理和膜过滤技术而发明的一种新的灌溉技术.以滴灌为对照处理,研究了温室条件下,痕量灌溉对球茎茴香(Foeniculum vulgare Mill.subsp.vulgare var.dulce(Mill.)Batt.)产量、干物质分配和水分利用率的影响.结果表明,痕量灌溉条件下球茎茴香球茎和地上部分(茎和叶)的鲜重和干物质重量显著高于滴灌条件下栽培的球茎茴香,且痕量灌溉的总耗水量显著低于滴灌.试验条件下采用痕量灌溉的水分利用率是滴灌的2.3倍.
Trace irrigation is a new irrigation technology based on soil capillary force principle and membrane filtration technology. With drip irrigation as a control, the effects of trace irrigation on Foeniculum vulgare Mill.subsp.vulgare var .dulce (Bat.) Batt. The results showed that the fresh weight and dry matter weight of bulbs and aboveground parts (stems and leaves) of bulb were significantly higher than those under trace irrigation Drip Irrigation Corms bulbs fennel, and the total water consumption of trace irrigation was significantly lower than the drip irrigation. Under the experimental conditions using trace irrigation water use efficiency is 2.3 times that of drip irrigation.
