叶面肥对一串红生长发育和生理指标的影响

Effect of Foliar Fertilizer on Growth and Physiological Indexes of Salvia splendens

基于盆栽一串红常见的施肥不足问题,通过对一串红叶面喷施不同浓度的养正叶面肥,研究了叶面肥对一串红生长发育的影响,分析了叶片中可溶性糖和淀粉含量的变化。结果表明:养正叶面肥能显著促进一串红的株高和开展度生长,增加开花数和花朵数量,促进其干物质积累,且在一定范围内,浓度越高,作用越明显,同时,养正叶面肥能促进叶片中可溶性总糖、蔗糖、果糖和淀粉的合成和积累。

Based on the shortage problem of potted Salvia splendens of common fertilization, through foliar spraying different concentrations of foliar fertilizer ideas, the effect of foliar fertilizer on the Salvia splendens growth and development of Salvia splendens was studied,the changes of soluble sugar and starch content in the leaves were analyzed. The results showed that ideas leaf fertilizer could significantly promote the of plant height and growth,flowering number and flower number increase, promote dry matter accumulation,and within a certain range, the higher the concentration, the more obvious role, at the same time, the ideas in foliar fertilizer could promote leaf soluble total sugar, sucrose, fructose and starch synthesis and accumulation.
