为明确精河县防护林中胡杨和沙枣树一年所需水量,试验设置灌水量为30 m3/(月·666.7m2)、60 m3/(月·666.7m2)和90 m3/(月·666.7m2)3个处理,对胡杨和沙枣树的叶片形态指标进行测定,进而计算出年需水量。
In order to clarify the water requirement of Populus euphratica and Zizyphus jujuba in shelterbelts in Jinghe County, the experiment set irrigation volume of 30 m3 / (month · 666.7 m2), 60 m3 / (month · 666.7 m2) and 90 m3 / (month · 666.7 m2 ) Three treatments, the morphological characteristics of leaves of Populus euphratica and Saussurea japonica were determined, and then calculate the annual water requirement.
