| 摘 要： | 为了解决早春苹果幼树抽条问题,避免因埋土造成的树体机械损伤,采用不同方位保温墙处理对苹果幼树进行了越冬试验.结果表明:正北向+覆膜处理能明显提高土壤温度,降低冻土层厚度,减少苹果幼树越冬抽条现象的发生.此法是西北干旱,半干旱地区苹果幼树安全越冬的一种新方法,具有操作简便、省力、成本低等优点.在苹果幼树露地不能安全越冬的干旱,半干旱地区具有推广价值.

| Abstract: | In order to solve sprouting problems of apple saplings in early spring,avoid mechanical damage caused by soil burying,overwintering experiment were carried out using insulation wall treatment on different directions.The results showed that treatment of due north direction and tectorial membrane could increase soil temperature obviously,lower permafrost layer thickness and decrease sprouting.It's a new approach for overwintering of apple trees in northwestern arid and semi-arid areas,which has the advantages... |
