摘要
本文通过不同施肥处理对春小麦同化产物供应与小花两极分化的关系进行了研究。结果表明,促进小花发育结实的关键是促进植株良好发育,提高同化产物供应水平,协调C/N。重施种肥是春小麦提高穗粒数的有效措施。
The test on the relationship between polarizing-development of floret and supply of assimilative products in spring wheat was done through different fertilizer treatment. Result showed that the key to improving development and fructification of floret was to promote the development of plant, increase supply of assimilative products and balance C/N in plants. More application of seeding-fertilizer is an effective method for increasing grain number per ear.
