摘　　要：在甘肃河西走廊川区,研究了皇冠梨不同间作物对树冠小气候、大青叶蝉发生和越冬后枝条生长发育的影响。结果表明:间作物洋葱和甜菜较高秆阔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,提高了树冠受光率、越冬后枝条萌芽率和新梢生长量。建议皇冠梨间作低杆窄叶间作物洋葱和甜菜来增加收入和降低大青叶蝉的发生。Effects of different intererop of Pyrus bretschnelder Rehd on climate of tree,occurrence of Cicadella viridis Linn6 and growth of branch after winter were studied in hexi corridor area of Gansu.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 nan＇ow 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.
