Orthogonal-gyrating design for five factors was applied in this study. The seeding time, sowing norm, nitrogenous fertilizer, phosphate fertilizer and potash fertilizer were used as variables with five levels per factor. The field trials were conducted at the Experimental station of putian Institute of Agricultural Science in 1987-1988. The result showed that the effect of seeding time on yield was most remarkable, followed potash fertilizer and sowing norm. An appropriate technical project of cnltivation for producing 250-300kg/mu was composted of following agricultural practies, such as sowing time11/8-11/11, sowing norm 5.86-7.10 kg/mu, carbamide 21.24-27.54 kg/mu, calcium superphate 23.5-29.0kg/mu and potassium chbo ride 10.83-13.28 kg/mu.
