| 摘 要： | 采用裂区设计,研究了不同种植密度下宁油16号油菜摘薹对产量、经济效益、生育进程及植株性状的影响。结果表明:1次摘薹后生育期推迟,一次分枝数和一次分枝角果数减少,二次分枝数和二次分枝角果数增加,三次分枝数和三次分枝角果少量出现。油菜籽产量略有减少,但总经济效益明显提高。2次摘薹后此现象更为明显。种植密度则以9.00万株/hm2最优。

Study on Picking Tender Shoots of Rape Variety Ningyou No.16 under Different Planting Densities |
| |
| Abstract: | Through split plot experimental design,the effects of picking tender shoots on yield,economic benefit,growth and development process and plant traits of rape variety Ningyou No.16 under different planting densities were studied.The results showed that after first picking tender shoots,growth and development were delayed,primary branch number and silique number of primary branch decreased,secondary branch number and silique number of secondary branch increased,and teriary branches and siliquae of teriary branch appeared slightly.The rapeseed yield decreased slightly,but the economic benefit rose significantly.After second picking tender shoots,this phenomenon was more obvious.The planting density of 90 000 plants/hectare was optimum. |
