不同基质和激素对4种花卉扦插的影响

Effects of Different Substrates and Hormones on the Cuttage of Four Flower Species

以长寿花、菊花、月季、三角梅4种花卉材料为研究对象,在设施条件下采用不同基质、不同激素研究最适宜的花卉扦插方法。结果表明:在相同基质的条件下,用NAA(500 mg/L)处理4种花卉,菊花生根率最高;用IAA(500 mg/L)处理,长寿花生长最佳;在NAA(500 mg/L)的处理下,三角梅生根率最高,但在IAA(500 mg/L)处理下,三角梅生长最佳。在相同激素的条件下,以草炭作为基质,菊花生长最佳;以粗砂作为基质,长寿花根系生长最佳;以蛭石作为基质,长寿花地上部分生长最佳;以珍珠岩作为基质,月季根系生长最佳;以蛭石作为基质,三角梅生长最佳。4种花卉的最适基质与激素组合为:菊花宜用草炭作为基质,NAA(500 mg/L)处理;长寿花宜用粗砂或蛭石作为基质,IAA(500 mg/L)处理;月季宜用以珍珠岩作为基质;三角梅宜用蛭石作为基质,IAA(500 mg/L)或NAA(500 mg/L)处理。

In this study,four kinds of flower materials,namely,long flowers,chrysanthemums,Chinese roses,and triangle plums,were taken as the research objects,and the most suitable flower-cutting method was studied by using different sub-strates and different hormones under the facility conditions.The results revealed that under the same substrate conditions,the rooting rate of chrysanthemum was the highest when treated with NAA(500 mg×L^(-1)).IAA(500 mg×L^(-1))resulted in the greatest growth of long-lived flowers.Under the NAA treatment(500 mg×L^(-1)),the rooting rate of Bougainbush was the highest,but under the IAA treatment(500 mg×L^(-1)),the growth rate of Bougainbush was the greatest.Under the same hormone conditions,the growth of chrysanthemum was the best,with grass used as the substrate.With coarse sand as the substrate,the root growth of long-lived flowers was the greatest.With vermiculite as the substrate,the aboveground part of the longevity flower grew best.With perlite as the substrate,rose root growth was the best;with vermiculite as the substrate,bougainvillea grows best.The optimal matrix and hormone combinations for the four kinds of flowers were as follows:Chrysanthemum should be treated with NAA(500 mg×L^(-1))with grass as the matrix;coarse sand or vermiculite should be used as the substrate,and IAA(500 mg×L^(-1))treatment should be used;and perlite should be used as the substrate for rose.Bougainvillea should be treated with vermiculite as the substrate,IAA(500 mg×L^(-1))or NAA(500 mg×L^(-1)).
