Abstract:

The four-factor quadratic rotational regression combination design was adopted to study the influences of different fertilizer application and planting density on the yield of middle-late-maturing soybean cultivar Changnong 18. The mathematical models between the yield and fertilizer application and planting density were established and analyzed. The comprehensive cultivation measures on Changnong 18 were as following: nitrogenous fertilizer 39.26-45.96 kg·ha^-1，phosphate fertilizer 168.79-196.44 kg·ha^-1，potassium fertilizer 70.86-79.77 kg·ha^-1，planting density of 24.8-25.9×104 plants·ha^-1.
