含5-氨基乙酰丙酸等养分水溶肥料对月季生长、开花及体内养分元素含量的影响

选用月季盆栽试验,以等养分水溶肥料、5-氨基乙酰丙酸盐溶液和含5-氨基乙酰丙酸等养分水溶肥料为试验材料,用清水做对照,研究了三者对月季生长、开花及植株体内养分含量的影响。结果表明,含5-氨基乙酰丙酸等养分水溶肥料更有利于月季花、茎、叶的生长,有利于促进月季开花率的增加和花色的改善;5-氨基乙酰丙酸有利于单位叶面积叶绿素含量的增加,叶绿素总量增加6.6%,而等养分水溶肥料使单位叶绿素含量降低;等养分水溶肥料较含5-氨基乙酰丙酸等养分水溶肥料更有利于月季植株体内N、P、K浓度的增加;3种试验处理均能不同程度地增加月季单株体内N、P、K的含量,特别是含5-氨基乙酰丙酸等养分水溶肥料处理的增产效果最显著,对单株月季体内NPK总含量的增加值达43.5%。

Effects of balanced nutrient soluble fertilizer with 5-ALA on the growth,flowering and nutrient content of Chinese rose

In order to investigate the co-effects of both plant growth regulator 5-ALA and balanced nutrient soluble fertilizer on the growth,flowering and nutrient contents of Chinese rose(Rosa hybrida),a pot experiment was conducted.Three treatments were balanced nutrient soluble fertilizer,5-ALA solution and balanced nutrient soluble fertilizer with 5-ALA,while water served as a check.All treatments were applied by foliar spray.There were three replications.The results showed that the application of balanced nutrie...
