麦椒套种对辣椒主要病虫的生态效应

The Ecological Effects on Pepper Main Diseases and Pests in the Pepper Wheat Inter-planted Field

连续 7a调查研究结果表明 :小麦辣椒间作套种的椒田辣椒苗期蚜虫、小叶病发生为害得到了有效控制 ;辣椒疫病、盲蝽、蟋蟀发生为害显著减轻 ,二代棉铃虫卵量减少 69.5 % ,幼虫量减少 3 7.2 % ,为害轻于单作辣椒。小地老虎、粘虫、斑须蝽、四代棉铃虫发生数量增大 ,为害重于单作辣椒田 ;辣椒炭疽病 ,日灼病发生为害程度明显加重。主要生态因素是麦套椒田小气候的改变 。
