摘  要：
[目的]了解饲用油菜产量的影响因素。[方法]选取饲用油菜品种华油杂62为试材,通过设置不同种植密度、施肥水平以及收获次数,研究其对饲用油菜产量的影响。[结果]饲用油菜分次收割时,施肥水平是影响其生物产量的主要因素;饲用油菜一次性收割时,种植密度是影响其生物产量的主要因素;一次性收割饲用油菜生物产量普遍明显高于分次收割产量。[结论]应根据实际生产需求,适当调整饲用油菜种植收获方式,饲用油菜的适宜种植密度为30万~45万株/hm~2,适宜施肥量为600 kg/hm~2。

摘  要：
[Objective] To determine factors affecting the yield of forage rape.[Method]Selecting forage rape variety Huayouza 62 as test materials,different planting densities,fertilization levels and harvest times were designed to study their effects on the yield of forage rape.[Result]When rapeseed was havested at different times,the fertilization level was the main factor that affected its biological yield; When the rapeseed was harvested at one time,the planting density was the main factor that affected its biological yield. One-time harvested feed rape's biological yield was significantly higher than that of harvest at different times.[Conclusion]The planting and harvest means of forage rapeseed should be adjusted according to the actual production demand. The optimum planting density of forage rape was 30 × 10~4-45 × 10~4 plants/hm~2,and the appropriate fertilization amount was 600 kg/hm~2.
