叶菜千疮百孔 提防猿叶虫
猿叶虫有大猿叶虫和小猿叶虫两种,多混合发生,主要危害十字花科中薄叶型的蔬菜,以秋季在油菜、萝卜、白菜、芥菜上危害最重,还可危害甘蓝、花椰菜、黄花菜等。猿叶虫的成虫和幼虫均危害蔬菜的叶片。初孵幼虫仅食叶肉,造成小凹斑痕。成虫和大龄幼虫把叶片
叶菜型甘薯蔓尖产量构成分析(英文)
Total yields of vine tip of seven varieties of Leaf-vegetable sweetpotato during 2006-2007 were investigated; proportions of the weights of leaf, leaf stalk and stem in total vine tip yield and their changes among varieties and during topping stages were studied. The results showed that vine tip yields of sweetpotato were significantly different among either varieties or topping stages; leaf yield accounted for about 51% of total vine yield, and changes in leaf yield among topping stages were higher than that among varieties; while yields of leaf stalk and stem each accounted for 25% of total vine tip yield, their changes among varieties were higher than those among topping stages. These results revealed the yield composition of vine tip of Leaf-vegetable sweetpotato, which provided scientific references for breeding and cultivating new Leaf-vegetable sweetpotato variety and its industrialization.
