以光钝感全雌性苎麻（简称ＮＣ苎麻）材料为毋本，用环剥法诱导通常在短日下才开花的雌雄同苎麻（简称ＳＭ苎麻）开雄花，组配ＮＳ组合。对６个ＮＳ组合与一个品种（细叶绿，ＣＫ）的研究，初步表明：ＮＳ组合的最大优点是纤维品质特优，头麻（１９９３）均在２０００ｍ／ｇ以上，三麻（１９９２）有５个组合超过１８００ｍ／ｇ的优质标准；纤维产量的对照优势率最高为６０．６％；植株高大，但茎数扳少；株高整齐度比无性繁殖的对照差，但其与产量几乎无相关；多数ＮＳ组合头麻有部分植株现雄蕾、散粉，亦有头麻不现蕾、散粉的组合。
To light insensitive all female ramie (referred to as NC ramie) material is not the use of girdling to induce the male and female ramie (SM ramie) flowering usually blooming in the short days open male flowers, group with NS combination. A preliminary study on the combination of 6 NS and one variety (slender green, CK) showed that the greatest advantage of NS combination was that the fiber quality was superior to that of the first combination (2000) 5 combinations of more than 1800m / g quality standards; fiber yield control of the highest rate of 60.6%; tall plants, but less than the number of stems; plant height uniformity than the cloned reproductive poor, but with almost no yield Related; most of the first combination of Nong Ma some plants are now male buds, loose powder, but also head numb budding, loose powder combination.
