新疆杨是一种抗病、速生、干直、质优、美观的好树种。但在盐碱地区,由于地下水位高,土壤含盐重,加之新疆杨插条发芽早,生根慢,容(?)“回芽”死亡,所以育苗成活率很低。 1977年,我团采取措施,加强林业,固定林管人员,确定育苗基地,全团育新疆杨100余亩,产苗31万株(其中根蘖苗1万余株),一般苗高1.5—2.0米(相当一部分3米左右),径粗1.5厘米,较好的地块亩产苗5,500株以上,成活率达91％,第一次闯过了新疆杨育苗的难关。1978年又育新疆杨200亩,取得了比1977年更好的成绩。
Xinjiang Yang is a good disease-resistant, fast-growing, dry, good quality, beautiful tree species. However, in saline-alkali areas, the seedling survival rate is very low due to the high groundwater level and salt content in the soil, as well as the early germination, slow rooting and tolerant “budding” of Xinjiang poplar. In 1977, our regiment took measures to strengthen the forestry, fixed forest managers, to determine the breeding base, the entire regiment of Xinjiang Yang more than 100 acres, 310,000 seedlings (including root tillering more than 10,000 strains), the general seedling height 1.5- 2.0 meters (a considerable part of about 3 meters) diameter of 1.5 cm, the better plots mu of more than 5,500 plants, the survival rate of 91%, for the first time broke through the difficulties of Xinjiang Yang seedlings. In 1978 and Xinjiang breeding 200 acres of Yang, made a better result than in 1977.
