早实核桃冬季新栽幼树不同防寒措施效果初探

Preliminary Study on Effects of Different Cold-proof Measures on Young Trees of Precocious Walnut in Winter

在石家庄市对冬季早实核桃新栽幼树进行了不同防寒措施试验。结果表明,新栽幼树弯倒埋土、套编织袋中间填土、重短截埋土等3个处理安全越冬率100%,春天幼树出土后韧皮部鲜绿色,萌芽早,长势强。缠裹报纸再缠编织袋条、先缠报纸后再缠塑料布、内套棉或化纤布管外套塑膜管袋等3个处理安全越冬率100%。在苗木成熟度差的情况下枝条梢部有15%~25%抽条率。缠编织袋条、缠塑料布等2个处理苗木的芽几乎全部坏死。绑裹谷类秸秆、缠报纸、涂聚乙烯醇、涂聚乙烯醇基部埋土、套棉质或化纤管状袋等5个处理,越冬抽条率在85%左右。

In this paper, test the young trees of Precocious Walnut of different cold proof measures in Shiji- azhuang city.The results showed that the newly planted saplings bent buried, woven sack middle filling, heavy cutting buried which the safe Overwintering Rate of the 3 treatments was 100%, After young trees were exca- vated in spring,the phloem fresh green, bud early, vigorous growth.Wrap the newspaper first, then wrap the bag, Wrap the newspaper first, then wrap the plastic cloth, first wrap cotton or synthetic cloth,then plastic bag of the coat which the safe Overwintering Rate of the 3 treatments was 100%.The sprout rate is 15%-25% in the case of poor seedling maturity. Wrapped bags, wrapping plastic cloth that the 2 treatments of seedlings bud necrosis. Bind cereal stalks, Bind newspaper, smear polyvinyl alcohol, smear polyvinyl alcohol and Buried soil in the base, wrap cotton or synthetic bag which the sprout rate is around 85% when overwintering.
