摘要: 【目的】研究不同播期、播量对油菜产量和品质的影响,为大面积推广复种饲料油菜提供理论支撑。【方法】大田试验,采用裂区试验,以播期为主区,播量为副区,设置2个播期、4个播量,3次重复,共24个小区。【结果】不同播期、播量对饲料油菜的湿重、株高、收获株数均影响显著,正常播种条件下2016、2017年饲油2号播量为12 kg/hm2时产量最高,分别为81 893.0和87 309.9 kg/hm2,且品质最佳。【结论】新疆地区复播饲料油菜生育期60~65 d,即可收割,需要≥10℃积温1 100~1 500℃,选择合适的播期和播量,产量和品质均可达到饲草要求,能够满足大部分地区麦后复种的要求,为冷凉地区麦后复种的首选。

Abstract: 【Objective】 The research time of no-till multiple cropping forage rape is short, and the research on suitable date and quantity of sowing in Northern Xinjiang Area is not enough, The purpose is to provide theoretical support.【Method】 The experiment adopted the split zone experiment design, with the sowing period as the main area and the sowing amount as the secondary area. Two sowing periods, four sowing amounts were set, and three replications were carried out in a total of 24 plots.【Result】 The results showed that sowing dates, sowing amounts had significant effects on wet weight, height of plant and number of harvested plants. Under normal seeding conditions, when the amount of Siyou 2 was 12 kg/hm2, the yield was the highest, 81,893.0 and 87,309.9 kg/hm2, in 2016 and 2017 respectively, with the best quality.【Conclusion】 Multiple cropping forage rape growth duration is 60-65 days, and the accumulated temperature is between 1,100℃ and 1,500℃(≥10℃). The selection of suitable sowing time and sowing quantity, yield and quality can meet the requirements of forage grass and the requirements of replanting wheat in most areas, and is the first choice for replanting wheat in cold areas.

Key words: forage rape; multiple cropping; sowing amount; sowing time; yield; quality
