摘要
大豆'丰收计划'的实施推动了大豆生产的发展。为了保证'丰收计划'圆满完成,除普及现有的优良栽培措施外,还必须探索今后应当推广的高产措施组合。大豆产量程序设计及栽培措施优化恰好可以服务于这一任务。
The multisite experiments were carried out with the same design of quadratic rotationin Laoning province in 1988.N,P,K and Zn fertilizers were the four experiment al factors and all of them had 5 levels.The results showed that the correlation between soybean yield and organic matter in soil was significant at10% (r=0.605,n=8),and between soybean yield and precipitation at 2%(r=0.722, n=8).All varieties of soybean have their own optimum fertilizer combinations for high yield.The average values were(NH_4)SO_4 12.62,CaH_4(PO_4)_2.H_2O 11.35,K_2SO_4 13.43,and ZnSO_4 1.21kg/Mu.At the present,they could guide the production of soybean in Liaoning province.
