摘　　要：2014—2015年在秦岭北麓麦区的周至县进行登峰168的高产栽培技术研究.试验在平衡施肥水平(纯氮225 kg/hm^2,磷肥(P_2O_5)195 kg/hm^2,钾肥(K_2O)150 kg/hm^2)基础上,以登峰168小麦品种为材料,采用播期和播量两因素二次D饱和最优试验设计,研究不同播期与播量对其生长发育及产量的影响.试验结果表明,播期与播量对登峰168生育期、群体及个体的质量、株高、赤霉病抗性、倒伏及产量等均有显著影响.通过寻优,在目标产量为9 000~9 750 kg/hm^2时,登峰168的适宜播种期在10月9日至10月18日,适宜的播种量为98.03~145.95 kg/hm^2.Research on the high yield cultivation techniques of wheat Dengfeng 168 was conducted in Zhouzhi county in 2014-2015,which locates in the north wheat region of Qinling mountains. In this test,based on the balanced fertilization level such as pure nitrogen 225 kg/hm^2,phosphate fertilizer（P2O5） 195 kg/hm^2,potassium fertilizer（K2O） 150 kg/hm^2,and taking wheat Dengfeng 168 as the cultivars,by using of the optimal design of two times saturation with two factors of sowing date and sowing rate,The effects of different sowing dates and sowing rates on the growth and yield of wheat were studied. The test results showed that the sowing date and the sowing rate had significant influence on the growth period,quality,plant height,scab resistance,lodging and yield of population and individual of wheat Dengfeng 168.Through the optimization,when the target yield is 9 000 ^ 9 750 kg/hm^2,the suitable sowing period for Dengfeng 168 sowing is from October 9th to October 18 th,and its suitable sowing rate is 98. 03 ^ 145. 95 kg/hm^2.
