摘　　要：利用不同类型的３个夏大豆品种，研究了施肥量密度对其产量的影响，分析了产量构成因素的差异，结果表明：齐丰８４适宜大密度高肥水栽培，７５１７－８８和齐丰８５０适宜稀植高肥水栽培。The effects of amount of applied fertilizer and population on yield were studied and differences of factors constituted yield among varieties were analysed with three summer soybean varieties of different types,The results showed that Qifeng 84 required cultural conditions of high fertilized water and big population,and 7517-88 and Qifeng 850 required cultural conditions of high fertilizer,water and suitable spaced planting.Among factors constituted yield,direct constribution of plants per hectare to yield was biggest,that of 100-seed weight was secondary and that of seeds per plant was smallest for Qifeng 84;direct contribution of 100-seed was biggest,that of seeds per plant was secondary and that of plants per hectare was smallest for 7517-88;direct contribution of seeds per plant to yield was biggest,that of 100-seed weight was secondary and that of seeds per plant was smallest for Qifeng 850.Cultural technics to ultra-high yield(over 4500kg/hm2)for three varieties were suggested by this experiment.
