摘要
研究白菜型冬油菜在河北省的适应性,为冬油菜在当地的合理种植提供理论参考依据。引种12个抗寒性不同的白菜型冬油菜品种,设置不同的播种时间(9月5日、9月11日、9月17日、9月23日、9月29日和10月5日),研究其对不同冬油菜的越冬率和产量的影响。结果表明,引种的12份材料均匍匐生长,生长点凹陷。9月29日前播种,各品种均能生长至10叶期,越冬率>97%,产量较高;9月29日后播种,各试验品种未能生长至10叶期,幼苗较小,越冬率较低,其中,10月5日播种产量均显著降低。相关性分析表明,产量与越冬率、根颈直径呈极显著正相关性,与播期呈极显著负相关性。根据聚类分析结果,可将12个品种分为2大类:Ⅰ类包括天油178、天油142、衡油6号和陇油9号,4个品种产量均较高,适应河北省衡水市的气候条件,适合当地种植;Ⅱ类包括天油4号、15QX60、陇油12号、16RTS309、衡油8号、16QD367和陇油8号,其中天油4号、15QX60、陇油12号、16RTS309、衡油8号和16QD367为1个亚类,产量稍低于Ⅰ类品种,可作为当地参考种植品种;陇油8号单独1类,产量最低,根据其生长习性推断其适宜衡水市以北地区种植。天油178、天油142、衡油6号、陇油9号可直接作为栽培品种在当地推广应用。天油4号、15QX60、陇油12号、16RTS309、16QD367、陇油8号等品种可以考虑向衡水以北地区引种试验。
Studying the adaptability of winter oil rapeseed in Hebei province would provide theoretical reference for the reasonable planting of winter rapeseed in the local area.Twelve varieties with different cold tolerance were introduced and different sowing times(Sep.5,Sep.11,Sep.17,Sep.23,Sep.29,and Oct.5)were set to provide technical support for the popularization and application of winter rapeseed in Hebei province.Results showed that 12 introduced varieties crawled in the field,and their growth points were under ground.All varieties grew to 10-leaf-stage if sowing before Sep.29,and overwintering rate was>97%,and yield were high.All varieties failed to reach the 10-leaf-stage if sowing after Sep.29,with smaller seedlings and lower overwintering rate,among which the yield sowing on Oct.5 significantly reduced.The correlation analysis demonstrated that the yield was positively correlated with overwintering rate and root diameter,and negatively correlated with sowing date.According to cluster analysis results,12 varieties can be divided into 2 major classes,classⅠincluding Tianyou178,Tianyou 142,Hengyou6,Longyou9,with high yield.These 4 varieties adapted to the climate condition of Hebei Hengshui and were suitable for local planting.ClassⅡincluded 8 varieties(Tianyou4,15QX60,Longyou12,16RTS309,Hengyou8,16QD367,and Longyou8),in which Tianyou4,15QX60 and Longyou12 were a subclass,with lower yield than class,thus they can be used as a reference to local plant varieties.16RTS309,Hengyou8,16QD367 were a subclass,of which yield was low,it was inferred that they were suitable for southern area of Hengshui.Longyou8 was a subclass,and its yield was the lowest.It was inferred that it was suitable for northern area of Hengshui according to its growth habit.Therefore,Tianyou 178,Tianyou 142,Hengyou 6 and Longyou 9 can be directly used as cultivated varieties at Hengshui.Tianyou 4,15QX60,Longyou 12,16RTS309,16QD367,and Longyou 8 can be considered to be introduced to the north of Hengshui for testing.
