优质油菜中油119、华杂2号和中双4号在高肥(300kgN/hm2)、中肥(225kgN/hm2)和低肥(150kgN/hm2)水平下,苗期均是随施肥水平的提高生长快、发棵早、光合速率高,到越冬期积累的于物质多;春后花期,中油119仍然是高肥水平的长势长相好,华杂2号和中双4号则以中肥水平的长势长相较好。三个优质油菜均以高肥水平的产量最高,但与中、低肥水平相比,各自的增产幅度不同,中油119高肥比中、低肥分别增产199%和35.8%,华杂2号分别增产9.2%和26.7%、中双4号分别增产8.8%和353%。
The high-yielding rapeseed oil 119, Huazha2 and Zhongshuang4 all increased with fertilization at seedling stage (300kgN / hm2), middle fertilizer (225kgN / hm2) and low fertilizer (150kgN / hm2) Grow fast, grow early, photosynthetic rate is high, to accumulate in wintering in the material and more; spring flowering, CNPC 119 is still a high level of fertilizer looks good, and Hua Za Shuang No. 4 and No. 4 in the fertilizer level Growing looks better. The yield of three high-quality rapeseed was the highest in high-fat level, but their yield was different from the middle and low-fat level. The yield of 119 high-fat medium-yield and medium-low yield increased by 199% and 35.8% 2 increased by 9.2% and 26.7% respectively, while Shuangzhong 4 increased by 8.8% and 353% respectively.
