一、引言: 应用微量元素处理作物种子,以增加农作物产量或改良品质,最近20年来,国内外已展开了研究,也获得了一定成绩。如保加利亚的波波夫院士等,以溴化钾和对苯二酚等药剂,在播种前处理棉花和水稻种籽,取得了15—20%的增产。在国内崔澂同志用微量元素处理小麦种子后,他认为对小麦幼苗生长有不同的促进作用,所以对后期生长的籽粒产 I. INTRODUCTION: The application of trace elements in crop seeds to increase crop yield or improve quality has been studied both at home and abroad in the recent 20 years and some successes have also been obtained. For example, the Popov academician of Bulgaria et al. Processed 15-20% of the cotton and rice seeds prior to sowing with potassium bromide and hydroquinone and other chemicals. In the domestic treatment of wheat with trace elements Comrade Cui Wei, he believes that the growth of wheat seedlings have a different role in promoting, so the late growth of grain yield
