摘要
Abstract
Manganese is an important element in soybean growth,in order to research the effect of Mn fertilizer on soybean in meadow chernozemic soil of Sanjiang plain,a pot experiment was conducted from 2008 to 2009. Hefeng 55 was treated by seed soaking and leaf spraying with different concentrations of Mn fertilizer during soybean growth stage and determined plant height, branch number, seed weight and other traits in soybean maturity. The results showed that plant height and nodes on main stem were first increased and then decreased and the bottom pod height was increased with the Mn concentration increase no matter seed soaking or leaf spraying,and branch number of treatment without Mn fertilizer was the maximum. When Mn concentrations in seed soaking increased,the number of one seed pod,four seeds pod,flat pods and 100-seed weight were first increased and then decreased,and seeds number per plant was increased. One seed pod,two seeds pod,flat pod and 100-seed weight were increased,and four seeds pod,seeds per plant were first increased and then decreased with the increase of Mn concentration in leaf spraying. Seed soaking with Mn had positive effect on soybean yield when without Mn spraying. The combination of seed soaking with 0.02 g ? Kg-1 Mn and leaf spraying with 0. 87 g ? Kg-1 Mn had the highest yield.关键词
