不同硫素水平对大豆硫素含量的影响

Effects of different sulfur levels on the content of sulfur in soybean

文章研究了不同硫素水平对大豆硫素含量的影响。结果表明,不同品种对施硫反应不同,高蛋白品种东农42施用硫肥,籽粒硫含量并不增加,而高油品种东农46和丰产型品种合丰25施用硫肥,籽粒硫含量提高。三个品种不同器官在生育期内硫素含量变化趋势不同,籽粒硫素含量在R4-R8时期呈现为“V”型变化。

The effects of different sulfur levels on the content of sulfur in soybean was studied in this experiment. The results showed that different varieties reacted differently to the amout of sulfur application. Sulfur levels did not increase the content of sulfur in the seeds of Dongnong 42 （high pro）, while it increased the content of the sulfur in the seeds of Dongnong46 （high oil） and Hefeng25 （high yield）. The content of sulfur in different organs of these three varieties showed different dynamics during the dynamic period according to Various sulfur applied levels. The content of sulfur in three varieties seeds took on ＂V＂changes from R4 to R8.
