The design method of quadratic rotation regression has been applied in the present experiment to study the relationship between soybean yield and the primary factors of soybean cultivation: density, nitrogen (carbamide), phosphorus (calcium superphosphate).Analyzing the primary composition, the effect rank of these cultivation factors on yield has been determind as follow: density carbamide calcium superphosphate.The integrated agricultural measures for obtaining the yield of 150 kg/mu in PUDOU-8008 are: 3.7-3.8 the thousand plant/mu; the dosage of carbamide 2.5-6.5 kg/mu and calcium superphosphate 9-21 kg/mu. For obtaining the yield of I00kg/mu in NlNGZHEN NO1 are,2.8-3.3 ten thousand plant in per mu and the dosage of carbamide 6-14 kg, calcium superphosphate 12-23 kg.
