摘　　要：春油菜为青海省种植面积第一的作物,其磷肥利用效率低,磷高效品种研究较少。为探讨青海甘蓝型春油菜不同品种之间磷效率的差异,筛选出磷高效品种,本研究采用大田单因素随机区组试验设计,分析在不施磷下7个甘蓝型春油菜青杂系列品种之间的磷效率差异。结果表明:‘青杂9号’磷利用效率显著高于其他供试品种,磷利用效率与籽粒产量呈显著正相关。因此,‘青杂9号’作为磷高效品种,可为甘蓝型春油菜科学施磷及选育磷高效品种提供参考。Spring rapeseed(Brassica napus L.)is the most planted crop in Qinghai.However,spring rapeseed has low phosphorous fertilizer use efficiency.The literature contains very few studies that phosphorus efficiency among different spring rapeseed varieties.In order to explore the difference in phosphorus efficiency between different varieties of Qinghai spring rapeseed and select high-efficiency phosphorus varieties,a field single-factor randomized block experiment design was used to analyze the differences in phosphorus efficiency among seven spring rapeseed varieties without phosphorus application.The results showed that the phosphorus utilization efficiency of’Qingza No.9’was significantly higher than that of other tested varieties.The phosphorus utilization efficiency was significantly positively correlated with grain yield.Therefore,’Qingza No.9’as a high-efficiency phosphorus genotype can provide references for scientific phosphorus application and selection of high-efficiency phosphorus varieties.
