苎麻切芽繁殖就是把跑马根切成0.5—1克的小段,龙头根、扁担根切成5克的小段,每段只留2—5个芽进行繁殖。它是湖南农学院近年研究成功的一种快速无性繁殖方法,1984年推广6万多亩,均获成功。优点是:后代分离变异小,可以完整地保持良种纯度和特性;繁殖系数大,比传统的大种根繁殖提高繁殖系数50倍以上;麻蔸的新生机体大、生活力强,能做到当年栽麻、当年受益、第二年高产。如益阳县农科所,1982年切芽繁殖15亩,栽后第二年调查,跑马根1克的,全年亩产363.9斤,比大种根(150—200克)亩产284.9斤的增产27.7%;龙头根、扁担根切成5克的,全年亩产318.6斤,比大种根繁殖的增产
Ramie cutting bud propagation is cut into 0.5-1 grams of horseradish small section, the tap root, flat root cut into small pieces of 5 grams, each leaving only 2-5 buds for breeding. It is a rapid asexual breeding method successfully researched by Hunan Agricultural College in recent years. In 1984, it spread 60,000 mu and all were successful. The advantages are: separation of small offspring offspring, you can completely maintain the purity and characteristics of the breed; breeding coefficient, breeding than traditional large multiplication factor to improve breeding more than 50 times; Manta newborn body, strong vitality, can do that year Planting Ma, then benefit, the second year of high yield. For example, Yiyang County Agricultural Science Institute, cut the buds in 1982 breeding 15 acres, planted the second year after the survey, Pamagnes 1 grams, the annual per-mu 363.9 kg, than the large-rooted (150-200 grams) 284.9 pounds per mu An increase of 27.7%; tap root, flat root cut into 5 grams, the annual mu produce 318.6 kg, than the large-scale breeding multiplication
