- 摘要:
- 利用一个主茎型和一个分枝型的大豆, 研究了大豆群体断条状况与产量补偿的关系, 结果表明, 随着断条长度的增加, 断条行产量呈二次方程式下降, 相邻全苗行产量呈二次方程式上升。分枝型大豆产量补偿能力大于主茎型大豆。主茎型大豆产量补偿主要靠增加主茎的有效节数、荚数、粒数和粒重:分枝型大豆则主要靠增加分枝数, 进而增加全株的荚数、粒数和粒重。断条还使其四周大豆的百粒重降低。
- Abstract:
- Study on the relat ionship betw een conditions of missing plant and plant yield compensation of soybeanpopulations , making use of a variety of main stem ty pe and variety w ith branch type .The results showed that ,in pace wi th increase of length of missing seeding , yield of the missing seeding row w ere fallen by quadratic equation, but yield of the full seeding row w ere increased by quadratic equation .Yield compensat ion of soybeanw ith branch were bigger than the main stem type soybean .Yield compensation of the main stem type soybeanw ere raised by No .of ef fective nodes, No .of pods , No .of seeds and seed w eight on main stem .Yield compensationof soybean wi th branch were raised by No .of branches and then increase by No .of pods , No .of seeds andseed weight per plant .100 seeds w eight of soybean around the missing seeding were fallen .
