摘要
利用一个主茎型和一个分枝型品系 ,研究了大豆在不同长度断条下的缺蔸效应。结果表明 ,分枝型大豆的缺蔸效应大于主茎型大豆 ;随着断条长度的增加 ,断条行和相邻全苗行的缺蔸效应均增大。分析了大豆品种区域试验中产生缺蔸效应值 ,建立了不同类型品种在不同断条方式下的断条长度与实际补偿长度的回归方程。用此方程即可对品种区域或其它小区试验中的缺蔸效应进行校正。
Study on the effects of vacancy plant of soybean, making ue of a variety of main stem type and a variety with branch.type the resuet shows that the effects of vacancy plant of soybean with branch is bigger than the main stem type soybean. In pace with increase of length of the breaking seeding, the effect of vacancy plant of the breaking seeding row and the full seeding row produce the offect of vacancy plant on the variety regional test. In accordance with the effect of vacancy plant of the breaking seeding row and the full seeding row, to build the regression equation on the change of compensable length is depend on increase of the length to break seeding. This equation is used about different type variety at the three kinds of situation to break seeding. The effect of vacancy plant on variety regional test is corrected by the equation.
