摘 要: 为探索植物生长调节剂对植物生长恢复的作用效果,选择月季(RosachinensisJacq.)作为研究对象,在生长旺盛期,选择生长良好和受损的植株分别用10mg L和20mg L的"施丰乐"溶液喷施(对照为清水)。结果表明,"施丰乐"不仅对月季的生长有较大的促进作用,对受损植株恢复生长也有明显效果,但对茎和叶的促进效果不同。经10mg L溶液喷施受损植株茎的增长幅度是对照的2 44倍,经20mg L溶液处理的未损植株叶的增长幅度为对照的4 41倍,其中前10d的作用效果最为明显,未损植株叶的增长幅度较对照高113 7%。 Both well-grown and injured Rosa chinensis Jacq.seedlings were sampled in order to probe the effects of plant growth regulator on the growth of the seedlings.During the vigorous growth period,'Shifengle' solution at the concentrations of 10 mg/L and 20 mg/L were used to respectively spray on the well-grown and injured seedlings (water as contrast).The results showed that not only the growth of Rosa chinensis Jacq. was greatly improved, the injured plants also recovered remarkably. However,there was some differences in its improving effects on stems and leaves. Amplitude of the stem of injured Rosa chinensis Jacq. sprayed by 'Shifengle' solution at the concentrations of 10 mg/L was 2.44 times of that of the contrast, and that of well-grown Rosa chinensis Jacq. sprayed at concentration of 20 mg/L was 4.41 times of that of the contrast. The effect was obvious in the first ten days,and the amplitude on stem of the well-growth Rosa chinensis Jacq. was 113.7% greater than that of the contrast.
