不同浇水量对4种盆栽草花生长及开花的影响研究

摘要

Effects of three kinds of water supply on Petunia,scarlet sage,marigold and Begonia semperflorens about three traits of growth and two traits of flower are analyzed. Stepwise regression equation is founded.The result show that Petunia and Begonia semperflorens growthing and flowering traits get better on 50%~65%of the water quantity, nutritional properties of marigold get worse and flowering properties get better.%该文分析了3种不同浇水量对矮牵牛、一串红、万寿菊、四季海棠3个营养生长性状和2个开花性状的影响,建立了多元逐步回归方程.结果表明:减少浇水量到50%~65%,矮牵牛、四季海棠营养性状和开花性状均得到优化;万寿菊营养性状下降,开花性状优化;一串红可以矮化株高,增加冠幅,花总数减少.
