High-Yield Cultivation of Wheat Variety'Zhongmai 895'in Guanzhong Irrigation Area Based on a Mathematical Model
A two-factor quadratic orthogonal regression experimental design was used by using DPS software,with yield(Y)as the target function.The sowing date(X1)and seeding rate(X2)were studied as factors to investigate high-yield cultivation techniques for wheat variety'Zhongmai 895'in the Guanzhong irrigation area.The results showed that the suitable sowing date and sowing amount of'Zhongmai 895'in Guanzhong irrigation area is October 5-10,and the sowing amount is 2.6075-3.4393 million basic seedlings per hectare.
