土壤盐渍化是影响灌区造林成效的重要因素。杨树在灌区造林中占有重要位置。而杨树,即使是典型的耐盐种——胡杨的抗盐性也有一定限度。正确掌握盐渍土特性和杨树的耐盐能力,以提高造林效果,是必须认真研究解决的问题。一、认真进行土壤调查工作掌握盐渍土各地块的性状,是正确选择树种和采取造
Soil salinization is an important factor affecting the afforestation effectiveness in irrigated areas. Poplar afforestation in the irrigation area occupies an important position. Poplar, even though it is a typical salt tolerant species, has some limits on the salt tolerance of Populus euphratica. Correct understanding of saline soil characteristics and salt tolerance of poplar trees in order to improve afforestation effect is a problem that must be seriously studied. First, conscientiously carry out soil surveys to grasp the traits of saline plots of various plots, is the correct choice of species and to take
