渝产白术主要病虫害发生规律及防治技术

Composition and Diversity of Arthropod Community in Different Types of Tea Plantations in Menghai Tea Area

中药材白术在栽培中常受到多种病虫害的危害。为减轻病虫害的危害,在重庆开展了白术病虫害种类的调查和常见病虫害的防治技术研究。调查表明：渝产白术产区危害较为严重的常见病害主要有根腐病、立枯病、白绢病、铁叶病及根结线虫病等,常见虫害主要有白术长管蚜、小地老虎、大青叶蝉、金龟子及白术术籽螟等。针对调查结果,总结了白术常见病虫害的发生规律、危害及防治方法。

The diversity of arthropod community was investigated systematically in three tea plantations, including the camphor-tea intereropping plantation, mango-tea intercropping plantation and pure tea plantation in Menghai tea area in Yunnan province during 2007～2009. The results were as follows： There were 121 species arthropods in 17 orders 67 families of insects, including 71 species in 12 orders 41 families of pests and 50 species in 9 orders 20 families of natural enemy insects. The Shannon＇s diversity index, the degree of homogeneity index and the degree of richness index of arthropod community in the camphor-tea and mango-tea intercropping plantation both were higher than that of pure tea plantation. It indicated that complex planting could improve diversity of arthropod community in the tea plantations significantly, and the structure was more reasonable.
