摘要
在不同密度下均匀与双株留苗对紧凑型玉米品种农大486个体及群体结构的影响进行了研究。结果表明,与均匀留苗相比,双株留苗使农大486植株的生产能力降低,生长势变弱,但改善了群体内部的光照条件,降低了倒伏。
The effects of leaving seedling doubly and evenly on compact maize Nongda 486 were studied .The result showed that compared with the leaving seedling evenly, in the term of the double seedling the yield and growing potential of Nongda 486 will decrease, but the light distribution in the community will be improved and the rate of lodging will be declined.
