摘 要：
作者在甘肃省河西走廊川区研究不同间作物对‘皇冠’梨树冠小气候、大青叶蝉发生和越冬后枝条生长发育的影响。结果表明,低秆窄叶间作物洋葱和甜菜较高秆宽叶间作物油葵和玉米降低了树冠内的湿度、叶片单叶成虫数、叶片虫害发生率、枝条单枝卵块数、枝条虫卵发生率和越冬后枝条死亡率,提高树冠受光率、越冬后枝条萌芽率和新梢生长量。建议‘皇冠’梨间作低秆窄叶间作物洋葱和甜菜,以增加收入、降低大青叶蝉的发生。并提出大青叶蝉发生规律和防治措施。

The result showed that the humidity of tree, the number of adult pest on single leaf, pest occurrence rate on leaf,the number of pest egg on branch, pest egg occurrence rate on branch and mortality of branch after winter were decreased, the light receiving rate of tree,germination rate after winter and growth of new branch were increased by low stem and narrow leaf crop onion and beet compare to high stem and broad leaf annuus and wheat. Low stem and narrow leaf crop onion and beet were suggested to intercrop for increase income and decrease occurrence of Pyrus bretschnelder Rehd,and prevention measures were proposed to occurrence regularity of Pyrus bretschnelder Rehd.
