摘　　要：对天然常绿阔叶林、旱冬瓜人工纯林的林下草果种植地,开展了不同林分郁闭度、种植株行距和施肥措施等栽培方式与草果萎蔫病发生关系的研究。结果表明,草果萎蔫病的发生与天然常绿阔叶林、人工旱冬瓜纯林两种林地类型的相关性不强。草果人工栽培、半人工栽培采取施肥壮苗措施,可提高草果植株对该病的抗病能力,有效降低其病害发生。在天然常绿阔叶林下栽培草果,林木郁闭度以0.5左右为宜,草果萎蔫病可得到有效控制。而在郁闭度为0.8的旱冬瓜人工纯林下种植草果,植株萎蔫病的发生与其种植密度的相关性不强。The relationship of cultural methods of Amomum tsao-ko and its occurrence of blight was investigated. The cultural methods was by using fertilizers in different stands of natural broad-leaf evergreen forest and artificial Alnus nepalensis forest. It showed that there was no significant correlation of the stands with the occurrence of the disease. Suitable use of fertilizer during plantation which increase resistance of the plant may effectively decrease the occurrence of blight by which. When planting Amomum tsao-ko under natural broad-leaf evergreen forest, the suggested closure rate is about 0. 5, the blight can be successfully controlled, and that of it in Alnus neoalensis artificial forest, the suggested closure rate is 0. 8. There was no significant correlation between planted density and the disease.
