摘要: 本文研究了甘蓝型油菜(B. napus L.)早熟品种的移栽叶龄。结果表明:在适期播种的前提下,增育小、中壮苗在4-6片叶、根颈粗4-6mm,苗高14-20cm时移栽,产量极显著高于7~8叶的大壮苗,并且,小、中壮苗移栽容易达到越冬、春发稳长,有利于早熟、早收。

Abstract: The transplanted leaf ages of early maturing variety rape(B. napus L.) was studied. The results showed that the yield of cultivating small and middle strong seedling transplanted 4-6 leaf, rhizome thick 4-6mm, seedling high 14-20cm is extreme notable higher than large strong seedling transplanted of 7-8 leaf, and small and middle strong seedling achieve strong seedling in winter, development and steady growth, advantageous early maturing and harvest in the prerequisite of beginning the sowing on good time.
