【摘要】 采用随机区组试验设计,探讨施肥对旱薄地谷子农艺性状及产量的影响。结果表明,相同磷钾水平下,施氮量与株高、穗粗、穗长、单株粒质量、穗粒质量、千粒质量、产量等性状均呈极显著或显著相关;相同氮磷水平下,施钾量与茎粗呈显著相关;随着施钾量的增加,穗长和产量呈增加趋势,穗粒质量呈降低趋势,但均不显著;相同氮钾水平下,施磷量与穗粒质量和产量呈显著相关;随着施磷量的增加,穗长、穗粗呈增加趋势。较高水平的氮、磷、钾配施能有效地改善旱薄地谷子农艺性状,提高产量。更多还原

【Abstract】 In order to investigate the effect of fertilization on agronomic traits and yield of millet on poor dry land, the experiment was conducted with random block design method. The results showed that nitrogen application showed significantly correlations with plant height, spike diameter, spike length, grains per plant, grain weight per spike, 1 000-grain weight and yield with the same phosphorus and potassium levels. Under the same nitrogen and phosphorus, potassium application correlated significantly with stem diameter; spike length and yield showed a trend of increase, while grain weight per spike reduced that no significant with the increase of amount of potassium application. Under the same nitrogen and potassium, phosphorus application correlated significantly with grain weight per spike and yield, spike length and spike diameter showed a trend of increase with the increase of amount of phosphorus application. Fertilization with a higher application level of nitrogen, phosphorus and potassium could effectively improve agronomic traits and yield of millet on poor dry land.更多还原
