繁殖苎麻有下述几种方法:①种子繁殖,繁殖速度虽快,但后代分离变异,影响原麻品质,不宜提倡;②种根、压条等无性繁殖,可保持种性和原麻质量,但速度慢,适应不了当前发展需要;③组织培养,水插法,需要一定的设备条件,大面积推广有一定的困难;④土培或砂培法扦插,也受季节的限制。为此,我们研究并运用了增高地温的手段,来提高苎麻扦插后的发根速度,促进根系的生长,成活率提高,收到了预期的效果。试验于3月5日进行,应用DV电加温线(提高地温)、尼龙薄膜覆盖保温保湿、芦帘遮挡直射光等手段,将苎麻的茎段直接扦插 Breeding ramie there are several ways: ① seed breeding, breeding speed is fast, but offspring separation and variation, affecting the quality of the original hemp should not be advocated; ② kinds of roots, pressure strips and other asexual reproduction, to maintain the quality and quality of the original hemp, Slow, can not adapt to the current development needs; ③ tissue culture, water plug method, the need for certain equipment conditions, large-scale promotion have some difficulties; ④ soil culture or sand culture cuttings, but also by the season’s restrictions. To this end, we have studied and applied the means of increasing ground temperature to increase the rooting rate of ramie after cutting, promote the growth of root system and improve the survival rate, and received the expected results. Test on March 5, the application of DV heating cable (to improve ground temperature), nylon film covering insulation moisturizing, shade blind direct light and other means to cut the ramie stem directly cuttings
