摘要
为探明新育成的杂交油菜品种黔油早2号在轻简化栽培中的适宜播种量,采取翻犁人工条播方式进行黔油早2号不同播种量试验,分析不同播种量油菜的田间苗数、农艺性状、生育期及产量的变化。结果表明:黔油早2号不同播种量间产量差异达极显著水平,播种量为200g/667m^2处理产量最高,为195.5kg/667m^2;其次是播种量为300g/667m^2和400g/667m^2处理,产量分别为187.8kg/667m^2和186.7kg/667m^2;播种量为700g/667m^2处理产量最低,为160kg/667m^2,且田间有部分植株倒伏。综合考虑生产成本,土壤墒情较好时,直播适宜播种量在200~300g/667m^2,若土壤墒情较差,播种量可选择400g/667m^2。
The seedling number,agronomic traits,growth period and yield of Qianyouzao 2planted by a drill seeding pattern under different seeding rate were analyzed to explore the proper seeding rate of Qianyouzao 2（a new hybrid rape variety with early maturity）in simplified cultivation.Results：The yield difference among different seeding rate treatments reaches a very significant level.The yield of Qianyouzao under200g/667m^2 of seeding rate,300g/667m^2 of seeding rate and 400g/667m^2 of seeding rate is 195.5kg/667m^2（the highest）,187.8kg/667m^2 and 186.7kg/667m^2 respectively.The yield of Qianyouzao 2under 700g/667m^2 of seeding rate is 160kg/667m^2 and some plants under 700g/667m^2 of seeding rate occur lodging.The proper seeding rate of Qianyouzao 2is 200~300g/667m^2 for direct seeding when soil moisture content is good but the proper seeding rate of Qianyouzao 2is 400g/667m^2 for direct seeding when soil moisture content is poor considering means of production cost comprehensively.
