摘要/Abstract

摘要： 测定了沟坡梯田核桃园采用不同水分调控措施后, 核桃叶片结构指标和单株产量。结果表明,灌水225 kg/ 株、灌水150 kg/ 株、覆膜、覆草处理对核桃叶片结构影响显著, 灌水225 kg/ 株处理使核桃增产43. 1 % , 中度修剪和覆草处理增产29 %以上。

关键词: 核桃, 水分调控, 叶片结构, 产量

Abstract: Structure indicators of walnut leaves and fruit yield of walnut were determined after applications of different water-controlled measures in walnut orchard in terraces of gully slope in Weibei loess plateau. Results showed that effects of 225 kg watering , 150 kg watering per tree , plastic film mulch and hay mulch on walnut leaves’structure were significant . Fruit yield per tree was increased more than 29 % by 225 kg/ tree watering, medium pruning , plastic film mulch , and hay mulch , of which fruit yield per tree was increased by 43. 1 % after
tree were watered by 225 kg water/ tree.

Key words: Walnut, Water-controlled, Leaf structure, Fruit yield
