摘要
以两因素二次正交回归方案设计试验,应用DPS软件,以产量(Y)为目标函数,将播期(X_(1))、播量(X_(2))做为因素进行研究,研究高产小麦品种中麦895在关中灌区的高产栽培技术。结果表明,中麦895在关中灌区适宜的播期和播量分别为,播期10月5~10日,播量为260.75~343.93万基本苗/hm^(2)。
A two-factor quadratic orthogonal regression experimental design was used by using DPS software,with yield(Y)as the target function.The sowing date(X_(1))and seeding rate(X_(2))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.
