摘要: 以甘蓝型油菜(Brassica napus)京华165为材料,设置播量、施肥水平与除草剂单因素试验,分析其对京华165生育期、产量及其产量形成的影响。结果表明,当播量为9.0 kg/hm2时,油菜长势最好,产量最高达3 061.6 kg/hm2;增大或者减小播量,产量均下降。西藏当地高产施肥油菜产量最大,但肥料用量大,生产很难达到,可用引进的NPK40%复合肥代替当地推荐施肥,以满足油菜生产需肥;用除草剂代替人工锄油菜田阔叶杂草。因此,当播量为9.0 kg/hm2,施用NPK40%复合肥,用除草剂除草,生育期适宜,京华165可实现较高产量,可逐步实现西藏油菜的轻简化生产。

Abstract: Using Brassica napus Jinghua 165 as material, a single factor experiment of sowing rate, fertilization level and herbicide was set up to analyze its effects on growth period, yield and yield formation of Jinghua 165. The results showed that when the sowing rate was 9.0 kg/hm2, the growth of rape was the best, and the yield was up to 3 061.6 kg/hm2; The yield decreased with the increase or decrease of sowing rate. The local high-yield fertilized rape in Tibet had the largest yield, but the amount of fertilizer was large, so it was difficult to achieve production. The imported NPK40% compound fertilizer could be used to replace the local recommended fertilizer to meet the fertilizer needs of rape production;Herbicides could be used instead of manual hoeing of broad-leaved weeds in vegetable fields. Therefore, when the sowing rate is 9.0 kg/hm2, applying NPK40% compound fertilizer and weeding with herbicides, and the growth period is appropriate, Jinghua 165 can achieve higher yield and gradually realize the light and simplified production of rape in Tibet.
