自1980年在本场固沙造林试验地内,对沙地几个造林树种的树叶含水量进行了测定。目的是了解与掌握生长在沙地树种的耗水情况,以及经营培育好沙地绿化成果。一、供试材料的选择采集与测定供试材料采自章古台固沙造林研究所固定沙地上人工栽植的樟子松(Pinus sylvestris L.var mongolica Litvin.)、油松(P.tabulaeformis carr.)、赤松 Since 1980, in the field afforestation experiment, the water content of leaves of several tree species in sandy land was measured. The purpose is to understand and master the water consumption of tree species growing in sandy land, as well as to cultivate the greening results of sandy land. First, the choice of materials for the test material collection and determination The test materials were collected from the Pinus sylvestris L.var mongolica Litvin., P.tabulaeformis carr. ), Red pine
