对胡杨次生林适宜灌溉量的研究表明 ,在一定范围内 ,林木材积生长量随灌溉量的增加而增加 ,在 0 (对照 )、75 0、1 5 0 0、2 2 5 0、30 0 0m3/hm2 .a处理中 ,年产材积量分别为3.76E - 0 5、3.42E - 0 5、4.94E - 0 5、0 .0 0 0 1 2 3、5 .75E - 0 5m3/株。 2 2 5 0m3/hm2 .a灌溉量的产材量最高 ,高含水量 1 1 0mm线上升的最高 ,较其他处理都为明显。在水资源日益短缺的塔里木河流域 ,胡杨林的灌溉量应以 2 2 5 0m3/hm2 .a为宜。
The research on appropriate irrigating amount of Populus euphratica secondary forest showed that in a certain range, the volume growth of timber volume increased with the increase of irrigation volume. At 0 (control), 75 0,1 5 0 0,2 25 0,30 0 0 m3 / hm2. a treatment, the annual volume of material volume were 3.76E - 0 5,3.42E - 0 5,4.94E - 0 5,0. 0 0 0 1 2 3,5 .75 E - 0 5m3 / strain. 2250m3 / hm2.a irrigation volume of the highest production capacity, high water content of 110mm line up the highest, compared with other treatments are obvious. In the increasingly short of water resources in the Tarim River Basin, Populus euphratica irrigation should be 2250m3 / hm2. A is appropriate.
