陕西省定边县位于东经107°15’~108°22’,北纬36°49’~37’°53’。系陕、甘、宁、蒙四省交界地,平均海拔1310~1907m,属黄土高原向内蒙高原风沙源过渡地段,南有白玉山,北邻毛乌素沙漠。土壤主要以黄粘土为主,属干旱半干旱风沙区,大陆性季风干旱气候。河流主要有八里河,属内陆河,四季多风少雨。因自然条件恶劣,植树造林育苗成本高,成活率低。针对新疆杨在我区育苗成活率低的现状,多年的实践经验,介绍一种提高新疆杨育苗成活率的技术和方法。
Dingbian County of Shaanxi Province is located at 107 ° 15 ’~ 108 ° 22’ east longitude and 36 ° 49 ’~ 37’ 53 ° north latitude. Department of Shaanxi, Gansu, Ning, Mongolia at the junction of the four provinces, with an average elevation of 1310 ~ 1907m, belongs to the Loess Plateau to Inner Mongolia Plateau sandstorm source transitional section, south Baiyu Mountain, north of the Mu Us Desert. Soil mainly yellow clay, is arid and semi-arid sand area, continental monsoon arid climate. The main rivers are Balihe, an inland river, the windy and rainy seasons. Due to poor natural conditions, afforestation afforestation costly, low survival rate. In view of the current situation of Xinjiang Yang nursery stock survival rate is low and many years of practical experience, this paper introduces a technique and method to improve the survival rate of Yang seedlings in Xinjiang.
