摘　　要：采用剪叶、去茎蘖的方法，人工摸拟稻从卷叶螟ＣｎａｐｈａｌｏｃｒｏｃｉｓｍｅｄｉｎａｌｉｓＧｕｅｎｉｅ、二化螟Ｃｈｉｌｏｓｕｐｐｒｅｓｓａｌｉｓ（Ｗａｌｋｅｒ）对水稻的危害所造成的产量影响．试验结果表明：早稻、一季稻去４根基本苗（简称茎）处理．其产量极显著降低．The loss of rice grain yeield caused by Cnaphalocrocis medinalis and Chilo suppressalis was estimated bymanually simulating through cutting leaves, removing stems and tillers. The result showed that the removal offour primary seedlings per hill (early season rice, single season rice) would substantially reduce rice grain yield.
