摘要
2005～2007年对大豆中微量元素合理施用量进行了探索研究。结果表明:在吉林省中部黑土区无论是高脂肪品种,还是高蛋白品种硫酸锌比较适宜用量一般为1.0 kg/667m2左右,硫酸锰比较适宜用量为1.0～2.0 kg/667m2。高脂肪品种硫肥比较适宜用量为3.0 kg/667m2,高蛋白品种硫肥比较适宜用量为1.0～2.0 kg/667m2。
With the increase of agricultural production level, effect of medium trace element becomes more and more obvious. Effect of application medium trace element on quality and yield of soybean cultivars with high oil and high protein from 2001 to 2002 were carried out the research and on the basis rational dosage of medium trace element from 2005 to 2007 were further research in black soil area of central Jilin province. The results showed that rational dosage of ZnSO4 generally was 1.0 kg·667m^-2 and rational dosage of MnSO4 generally was 1.0-2.0 kg·667m^-2 whether high oil content or high protein soybean cuhivars. Rational dosage of S fertilizer was 3.0 kg·667m^-2 to high oil content soybean cuhivars and was 1.0-2.0 kg·667m^-2 to high protein soybean cuhivars.
