EM應用於網室番木瓜之栽培

EM Applicationin Protected Papaya Culture

有效微生物菌（Effective microorganism, 簡稱EM），使用於台灣網室木瓜栽培，使葉片之總葉綠素含量，較對照組為高；對於深耕後之木瓜園，EM處理使其根群發育較對照組為優，且總新根數較對照組為多，根乾物重遠比對照組為重；在輪點毒素病及紅蜘蛛危害之罹病率中，EM處理時其罹病率遠比對照組為低；處理EM使其糖度與厚度較對照組為高。EM確實可提高果實品質，提高農民收益。

In Taiwan, it has been shown that the application of effective microorganisms (EM) to papaya in a netted house increases the overall chlorophyll content to a level higher than the control group in any months. In the case of the deep-rooted papayas, the application of EM enhances the root mass development, better than the control group, either in root development or in the number of roots. This also reflects the quality of fruits, in terms of the sweetness and thickness of fruits, they are much higher than the control group. The roots dry weight increases significantly after the EM treatment. Compared with the control group, the contract rate of diseases caused by ringspot virus or red spiders is far lower. We are convinced that the application of EM can improve profitability for farmers.
