| 摘 要： | 目的]为冀张薯8号在榆林地区实现优质优用提供理论依据。方法]以冀张薯8号为试材,研究不同播期和密度对冀张薯8号生育期、株高和产量的影响。结果]在同一栽培密度下,各处理间生育期随着播种期推迟而逐渐缩短。处理A2全生育期最长,单产最高,为24415 kg/hm2;在同一播期条件下,株高随种植密度的增加而增加,产量随密度增大表现为先增加后下降的趋势。处理B2产量最高,单产达21 315 kg/hm2。结论]冀张薯8号在榆林地区最佳播种时间为4月底,最佳栽培密度为4.50万～5.25万株/hm2。

| Abstract: | Objective] The aim was to provide the theoretical basis for the highest effciency utilization of Jizhangshu8 in Yulin region.Method] With Jizhangshu8 as tested material,the effects of different sowing date and density on growth period,plant height and yield were studied in Yulin region.Result] Under the same plant density,with the delaying of sowing date,the growth period gradually shorten.The longest growth period and the highest yield was treatment A2,and the yield was 24 415 kg/hm2.Under the same sowi... |
