河北省太行山中南部核桃栽植时期及栽植技术研究

A Study on Planting Period and Technique of Walnut (Juglans regia L.) in Central-south of Taihang Mountains in Hebei Province

于2001年10月-2003年10月连续进行了不同栽植时期以及栽植技术对核桃幼树成活及生长发育影响的研究。结果表明：秋栽后用聚乙烯醇涂干处理，成活率高达95％以上，翌春萌芽比春栽早10d以上，新梢生长速度快，春季抽干高度短，平均枝条长可达45cm以上，是最好的技术组合；秋栽不涂干处理，成活率较低，不足60％，并且抽干高度长，发枝部位低；春栽成活率高，但是缓苗期长，新梢发育慢，平均枝条长短，仅为20—30cm。

Effects of different planting period and technique on young plant survival and growth and development of walnut from Oct. 2001 to Oct. 2003 were studied. The results showed that the survival rate of the seedlings planted in autumn then painted the trunk with polyvinyl alcohol was up to 95%, in next spring the sprouting time was 10d earlier than those planted in spring, the growth rate of shoots was fast, withered branch part was short, shoot length was up to 45 cm, so it was the best technique assembled. The survival rate of the seedlings planted in autumn but didn＇t painted the trunk was lower than 60%, and the withered branch part was long, this leaded to the sprouting bud was near to ground. The survival rate of the seedlings planted in spring was high, but the revival time was long, and the growth rate of shoot was slow, the average length of shoot was short ,only 20 - 30 cm.
