摘要
在和田绿洲外缘新开发区 ,采用滴灌技术营造常规经济林、防护林树种 ,收集试验区基本气象资料 ,用彭曼公式估算和田地区 3～ 10月作物的蒸发蒸腾量 ,根据各树种生长期内的需水特性 ,计算耗水强度、灌水定额 ,确定各树种的灌溉周期 ,灌溉定额。借此来指导在干旱区采用先进滴灌设备节水造林工作。
Using drip irrigation in Hetian Prefecture was planted non timber product forest and protection forest.Was ectimated evaporation and tran spirition rate of Hetian area from March to October.According to water requirement of every species in growth period were calculated water consumption,irrigating quota,and the irrigation cycle and irrigation quota were determined for every species.
