摘要
通过吉林省两个不同气候区大豆试验研究表明:施用钾肥能够促进大豆生长发育,提高大豆产量,同时还能促进对氮磷的吸收。施用钾肥60 kg/hm2,钾肥利用率最高,并可获得最大的经济效益。
The two-sites experiments established on the different climate zone of Jilin province showed that K fertilizer application could improve growth and yield for soybean and promote N and P uptake in the soybean plant. 60kg K2O /ha application for soybean got the highest K use efficiency and produced the largest profitability.
