【摘要】 为了探索优质杂交油菜黔黄油21号在不同种植密度下的产量及主要品质性状的表现,分别在贵州遵义产区稻田免耕移栽条件下进行了黔黄油21号不同种植密度的大区对比和单因子随机区组试验。结果表明:黔黄油21号含油量随密度的增加而增加,芥酸、硫甙、蛋白质等品质性状呈现无规律的变化趋势,均符合国家优质油菜标准。黔黄油21号移栽密度在6 000~8 000株/667m2范围内,可获得200 kg/667m2以上的产量水平,综合性状良好,有效分枝数及有效角果数较多;最佳种植密度为6 000株/667m2,在该密度下可获得202.35 kg/667m2的高产水平。更多还原

【Abstract】 Qianhuangyou 21,a new hybrid rapeseed variety,was cultivated in rice field under different planting density and no-tillage transplanting by using plot comparison test and single-factor randomized block experiment to study the effects of different planting density on yield and main quality characters of Qianhuangyou 21.The results showed that the oil content of Qianhuangyou 21 increased with the increase of planting density,erucic acid,glucosinolate and protein content presented the irregular variation trend but the content of quality characters meets national high quality rapeseed standard.The yield of Qianhuangyou 21 reaches above 200kg/667m2 under 6 000～8 000 plants/667m2 transplanting density because of good performance of comprehensive characters and more effective branches and effective pods.The optimum planting density for Qianhuangyou 21 cultivation is 6000 plants/667m2 and its yield is up to 202.35 kg/667m2.更多还原
