不同播种移栽方式对油菜生长发育及产量的影响

为探索不同播种移栽方式对油菜生长发育及产量的影响,以免耕直播油菜为对照,开展了油菜翻耕育苗移栽和免耕直播对比试验。试验结果表明:与免耕直播油菜相比,育苗移栽处理能促进油菜生育前期的生长发育,增加油菜植株的绿叶数,提高油菜植株的生物学产量。同时,育苗移栽油菜有效分枝高度明显低于对照,一、二次分枝数及有效角果数则均高于对照,从而提高了油菜产量,其产量比对照增加23.49%。

Effects of Different Sowing and Transplanting Patterns on Growth,Development and Yield of Rape

In order to explore the effects of different sowing and transplanting patterns on the growth,development and yield of rape,the comparative tests of rape between the treatment of seedling-transplanting with tillage and the treatment of direct seeding without tillage(CK) were conducted in the paper.The results showed that: comparing with CK,the treatment of seedling-transplanting with tillage could promote the growth and development of rape at the earlier growth stage,and increase the number of green leaves and biological yield of rape plants.Meanwhile,the treatment of seedling-transplanting with tillage could significantly reduce the height of effective branches of rape plants,and enhance the number of the first branches,the second branches and effective pods.Therefore,the yield of rape in the treatment of seedling-transplanting with tillage was 23.49% higher than that in CK.
