为解决芍药(Paeonia lactiflora Pall.)生产中的扩繁问题,进行了引种芍药分株繁殖研究,总结出一套实用的分株繁殖技术。(1)引进芍药品种的最佳栽植时间是10月中旬,此期栽植的芍药萌发整齐,生长量大,成活率和成花率高。(2)三种根部处理发芽率影响不大,而是发芽时间不同。(3)不同根部处理对引种芍药成活、生长、成花率的影响各有不同。2年生芍药苗试验数据综合分析结果表明,在芍药母株根系健康、土壤无严重病虫害的情况下,用草木灰加50mg/L的3号ABT生根粉搅成糊状涂抹伤口,稍置后种植是最佳选择,且处理操作简单易行,成本较低。若芍药母株或土壤有严重的病虫害,选择用0.1%浓度的甲基异柳磷+50%甲基托布津可湿性粉剂0.14%浓度的溶液水溶液浸泡,浸泡30min,晾干后栽植效果最好。
In order to solve the problem of propagation in the production of Paeonia lactiflora Pall., We introduced the introduction of Paeonia lactiflora Pall., And summarized a set of practical ramets breeding techniques. (1) The best planting time for the introduction of peony varieties is in mid-October. The peony grown in this period germinated neatly with large growth and high survival rate and flowering rate. (2) The germination rate of three kinds of root treatment has little effect, but the germination time is different. (3) Different root treatments have different effects on the survival, growth and flowering rate of introduced peony. The results of perennial peony seedling test data showed that the roots of peony parent plants were healthy and the soil was free from serious pests and diseases. The application of 50mg / L ABT rooting powder (50mg / L) The best choice, and the processing operation is simple and easy, the cost is lower. If the peony parent plant or soil have serious pests and diseases, choose 0.1% concentration of methyl isofenphos-methyl 50% thiophanate-methyl WP 50% aqueous solution soak, soaking 30min, drying the best planting effect .
