| 摘 要： | 本项研究在中国西北塔里木河下游兵团农垦区红枣生态经济林进行,用微型蒸渗仪（MLS）测定了根灌与滴灌条件下的田间土壤蒸发。通过试验研究,初步提出了可用于西北干旱区测定滴灌与根灌土壤蒸发的MLS的最佳长度,同时探索了根灌与滴灌的土壤蒸发规律,对根灌的节水空间进行了分析。根灌与地表滴灌的土壤蒸发对比试验表明,同等气象、灌溉条件下,根灌土壤蒸发损失约为地表滴灌的一半；而根灌与滴灌带的土壤蒸发对比试验则表明,同等气象、灌溉条件下,滴灌带土壤蒸发损失量比流速较大的根灌平均高12%左右。本项研究为根灌技术在干旱区的推广应用提供了依据。

| Abstract: | An investigation was carried out to compare the water-saving effects between the rhizospheric irrigation and drip irrigation in an ecological economic forest of red jujube in Xinjiang, China. The soil evaporation was monitored with micro-lysimeters made of PVC. The results showed that: (1) A micro-lysimeter with diameter of 12 cm and height of 15 cm could be used to well monitor the soil evaporation in the studied sites. (2) The soil water loss by evaporation in rhizospheric irrigation was about 50% of that in drip irrigation, and about 11% less than that in the tape-drip irrigation |
