二十多年来,我们从精河沙区立地条件出发,选引了50多个树种,经过比较鉴定,从中选出了11个优良固沙造林树种。其中,白梭梭、梭梭柴、艾比湖沙拐枣、花棒适宜于沙层含水量为1.6—2.6％、土壤盐分为0.1344％、无地表径流、沙粒流动性大的沙地;梭梭柴、剌毛红柳、胡杨、小沙枣适宜于生长季节土壤含水量为13.9—21.2％、土壤盐分为0.53—1.21％、无地面径流或有洪水淤灌、沙粒流动少的半固定沙地和盐渍化沙地;白柠条、头状沙拐枣、白榆、二白杨适宜于土壤含水量为3.2％以上、土壤盐分低于0.3％的半固定沙地和丘间低地。现将这11个树种分别简介如下。
For more than two decades, we selected more than 50 tree species from the site conditions of Jinghe Sandy District. After comparison and identification, we selected 11 excellent sand-fixing tree species. Among them, the white Haloxylon ammodendron, Haloxylon ammodendron, Abercrombie and Botanical garden, the stems and stems of Aibi Lake were suitable for sand with water content of 1.6-2.6%, soil salt content of 0.1344% and no surface runoff and sand flow. Haloxylon ammodendron, Prunus humilis, Populus euphratica and Przewalsia both are suitable for growing season soil moisture content of 13.9-21.2%, soil salt content of 0.53-1.21%, without surface runoff or flood silting, less semi-fixed sand flow Sandy land and salinized sandy land. The white kelp, head jujube, white elm and poplar are suitable for semi-fixed sandy land and low lying mound with soil moisture content of more than 3.2% and soil salinity less than 0.3%. Now these 11 species are introduced as follows.
