摘要
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%。
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 nutrient soluble fertilizer with 5-ALA had positive effects in promoting the growth of Chinese rose,increasing the Chinese rose flowering rate and improving the color of Chinese rose flower.Single application of 5-ALA solution could increase chlorophyll content of per unit area of leaf by about 6.6%,while single application of balanced nutrient soluble fertilizer could lead to significant decrease in the chlorophyll content of per unit area of leaf.Balanced nutrient soluble fertilizer was more conducive to increase nitrogen content,phosphorus content and potassium content than that of the balanced nutrient soluble fertilizer with 5-ALA.Nitrogen content,phosphorus content and potassium content of per single plant were increased by applying the three different fertilizers,among them the balanced nutrient soluble fertilizer with 5-ALA had the best yield improving effect with total primary nutrient increased by 43.5%.
