美国伊里诺斯州大学的研究组,用几种杂草研究了叶绿素的合成特性,提出了新的除草方法。夜间,往长满杂草的庄稼地里喷洒含有氨基酸的溶液,植物在合成叶绿素时氨基酸被利用。夜间,杂草把氨羞酸改变成一种物质,这种物质白天在阳光作用下转 The research group of the University of Illinois, USA, studied the synthetic characteristics of chlorophyll with several weeds and proposed a new weeding method. In the evening, the weedy crops are sprayed with solutions containing amino acids, which are used by plants to synthesize chlorophyll. During the night, weeds change carbamazan into a substance that turns during the day under the sunshine
