| 摘 要： | 试验研究了不同硫素水平对大豆干物质积累的影响。结果表明,不同大豆品种地上部干物质积累量对硫肥敏感性不同,黑农35在每千克土施硫磺粉0￣0.04g范围内增加硫肥可促进干物质积累,施0.06g硫磺粉时降低;北9395和东农46均是每千克土施0.04g硫磺粉的处理干物质积累量在某些生育时期表现出降低的效应。根系干物质积累量的变化趋势与地上部一致,二者呈显著或极显著正相关,施硫可以协调大豆植株地上部和根系的平衡生长。苗期至始花期硫肥处理对干物质积累量的影响很小,盛花期后处理间作用效果差异增大。

| Abstract: | Effects of sulfur on dry matter accumulation of soybean were examine d in this research. The results showed that the reaction of dry matter accumulat ion to sulfur was different according to cultivars. Dry matter weight of Heinong 35 was enhanced with the increase of sulfur between the application 0- 0.04 g·k g-1 earth, and decreased under 0.06 g·kg-1 earth. While, for Dongnong46 and Bei 9395, 0.04 g·kg-1 earth application seemed to be an over dressing. Dry matter w eight in the shoots and roots showed a significantly or most significantly posit ive correlationship, which meant that a comparatively coordinative growth could be achived when sulfur fertilizer was applied. The effect of sulfur on the accum ulation of dry matter was minor from seedling to initial-flowering stage, and it changed appreciably after bloom-flowering stage. |
