- 摘要:
- 为更好地利用冬季时间进行百里香的温室扦插育苗，以百里香当年生枝条为试材，采用3×5两因素完全随机设计，研究了不同浓度的“强力生根粉”溶液对百里香当年生枝条的上段、中段和下段等不同类型插穗的生根数、根长、生根率和株高、成苗率等指标的影响。结果表明：上段插穗的生根数、根长、株高、生根率和成苗率均显著或极显著优于中、下段插穗；“强力生根粉”的不同浓度处理同一类型的插穗后，扦插苗的生根数、根长、生根率和株高、成苗率5项指标均随浓度的升高而先增大，达到最大值后又随浓度的升高而下降；用100 mg/L的“强力生根粉”处理百里香枝条上段插穗，扦插苗的生根数为25.38条，平均根长为31.00 mm，株高达8.95 cm，生根率和成苗率均达100%，在试验所设的15个处理组合中成苗效果最好。
- Abstract:
- In order to raise the seedling efficiency by cutting of Thymus mongolicus in greenhouse in winter，taking the current year branches of T.mongolicus as experimental material，the experiment was designed as 3×5 factorial and arranged randomly，effect of different types of cuttings（top，middle and lower）,different concentrations of ‘strong root powder’on the rooting number，root length，plant height，rooting percentage and seedling percentage of T.mongolicus Ronn.were studied.The results showed that the cutting from the top of branches were significant or very significant better than the other two kinds on the rooting number，root length，plant height，rooting percentage and seedling percentage;for the same type of cutting，the 5 indexes were increasing with the higher concentration of the rooting powder，and then descending with the lower concentration after the 5 indexes were up to the most;the best treatment in all the 15 treatments was the cutting from the top of the branches,after cutting the end of them were dipped in the rooting power solution with 100 mg/L，the rooting number was 25.38，the average root length was 31.00 mm，the plant height was 8.95 cm，rooting percentage and seedling percentage were all 100%.
