| 摘 要： | 庆阳市新栽早实核桃越冬易受冻害,2011-2013年选择定植1-2年的山地核桃幼园,开展核桃幼树越冬防寒单项与组合试验。结果表明：单项防寒措施以套袋填土和压倒埋干效果最好,枝干绑草效果次之;组合防寒措施以树干刷植物防冻剂＋绑草和树干刷聚乙烯醇＋绑草的防寒效果最好,枝干涂白＋绑草效果较差。在庆阳山地核桃幼园越冬管理中,宜采取枝干套袋填土、压倒埋干等防寒措施,可有效保证新栽核桃幼树安全越冬;同时采取树干涂刷植物防冻剂＋绑草和涂刷聚乙烯醇＋绑草等防寒措施,也对新栽核桃幼树安全越冬有较好的效果。

| Abstract: | Early-fruiting walnut susceptible to frozen injury over winter in Qingyang city, single and composite tests of overwintering were carried out in walnut orchards which transplanted 1-2 a in hilly area. The result showed that： in the individual test, bagging-filling and trunk buried on root treatments are best： second is wrapping straw in the branches; in composite tests, the effect of brush antifreeze＋poly （vinyl alcohol） ＋wrapping straw is best; the effect of white paint＋wrapping straw is poor. In the overwintering management of walnut orchards in Qingyang hilly area, the techniques of newly planted walnut young trees overwintering safety： at and wrapping straw also has good effect for overwintering. bagging-filling and trunk buried on root can keep the same time, using antifreeze, poly （vinyl alcohol） |
