摘要: 通过对棉花播期、密度、行距和果枝数的复因子试验以及氮、磷、钾肥的单、复因子试验,确定了太行山丘陵区旱地棉花在干旱气候年型的播期和主要群体结构指标的优化组合,明确了该区旱地棉花氮、磷、钾肥的增产效应及最佳配比,提出了适合该区旱地棉花高产、稳产的技术路线.
英文摘要: The subject of this study was to select the superior combination of different sowing dates, densities of population, row distances, and numbers of fruit branch, as well as the optimum ratio of nitrogen, phosphate, and kalium fertilizers in cotton plant growing in dry year in the hilly region of Taihang Mountain. Based on this, the key cultural techniques for higher and stable yield of cotton in such kind of region were put forward.
