根种繁殖 秋末冬前或春初选择无混杂,无衰老、无病虫的粗壮麻蔸,用刀砍去萝卜根和腐根,再用薄口快刀把龙头根、扁担根和跑马根切成50～100克一块直接栽入新麻园。此种方法简便易行,能保持原品种特征特性,新麻产量较高,但繁殖系数小,挖1亩老麻只能栽10亩左右的新麻,大面积发展,种源不够,运输不便,一般适应于老麻区 Roots Breeding autumn or winter before winter or early spring choose no mixed, non-aging, non-pest moths, chopped radish roots and rot roots, and then the thin cut knife to the tap root, flat root and race horse root cut into 50 ~ 100 grams a piece directly into the new Ma Park. This method is simple and easy, can maintain the characteristics of the original varieties, higher yield of new hemp, but the breeding coefficient is small, digging 1 hectares of old hemp can only planted about 10 acres of new hemp, large area development, provenance, transport inconvenience , Generally adapted to the old Ma area
