摘要
在干旱地区梭梭是退耕还林还草工程中的先锋树种。试验观测梭梭新枝生长高度随着时间变化呈对数关系,基径呈幂指数关系。实测全生育期Ⅰ、Ⅱ、Ⅲ处理下梭梭的耗水量分别为220.8mm,78mm,60mm。生长速度随着耗水量的增大而增加,新生枝长的生长量与耗水量之间符合指数函数关系。
Haloxylon ammodendron bge is the vanguard tree to the engineering of returning to forests and grasses In dry regions. Experiments show that the growth height of the new tree branch of Haloxylon ammodendron bge presents logarithms relation and the Ji path presents Mi index number relation because time change. Actually the consumes amount of water of Haloxylon ammodendron bge distinguish for the 220. 8 millimeters, 78 millimeters, 60 millimeters by measuring to all growth to expect the Ⅰ、Ⅱ、Ⅲ processing descends. The grow speed increases with the aggrandizement of the consume amount of water, the amount of growth and the consume amount of water of the new tree branch to match index number function a relation.
