水分调控对核桃叶片结构和产量的影响

Effect of Different Water-controlled Measures on Leaf Structure and Fruit Yield of Walnut

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 2 2 5kg/株、灌水 15 0kg/株、覆膜、覆草处理对核桃叶片结构影响显著 ,灌水 2 2 5kg/株处理使核桃增产 4 3.1% ,中度修剪和覆草处理增产 2 9%以上。

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 225kg watering,150kg 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 225kg/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 225kg water/tree.
