对红麻品种浙红8310的农艺性状(全秆产量、纤维长度分布、化学成分)和全秆硫酸盐纸浆特性(总浆得率、纸浆纤维长度分布、纸页强度)在浙江安吉干旱丘陵区13.5万~40.5万株/hm2的4个种植群体上进行了测定。在农艺性状上，随着种植密度的增加和坡地海拔的降低，最终的全秆产量越高。韧皮部和芯部的平均纤维长度最大，为22.5万株/hm2。纤维素含量随着植物种群的增加而增加。从红麻全秆硫酸盐制浆特性来看，总浆得率随种植密度的增加而降低，最大差异约为1.3%。叶面强度和平均纤维长度在225000-315000株/hm2左右时达到最大值。纸浆强度(断裂长度、耐破指数和耐折度)在225000株/hm2的株数时最大，撕裂指数在31.5万株/hm2的株数时最大。综合农艺性状和全秆硫酸盐浆特性，确定了中国旱地红麻全秆硫酸盐法制浆造纸的适宜种植密度为22.5万株/hm2~31.5万株/hm2，略高于纺织用红麻麻皮生产密度。
Agronomic properties (whole stalk yield, fiber length distribution, chemical composition) and whole stalk kraft pulp characteristics (total pulp yield, pulp fiber length distribution, pulp sheet strengths) were examined for kenaf (variety Zhehong 8310) at four plant populations, ranging from 135 000 to 405 000 plants/ha on arid hillside land at Anji, Zhejiang, China. For agronomic properties, the final whole stalk yield was higher as the plant population increased and as the altitude of the location on the slope decreased. Average fiber lengths of bast and core showed maxima at 225 000 plants/ha. Cellulose content increased as the plant population increased. For the kraft pulp characteristics of kenaf whole stalk, the total pulp yield was lower as the plant population increased, with the maximum difference about 1.3%. Sheet strengths and average fiber length attained maxima at around 225000–315000 plants/ha. The largest pulp strengths (breaking length, burst index, and folding endurance) were seen at a plant population of 225000 plants/ha, and the largest tear index was seen at a plant population of 315 000 plants/ha. When the agronomic properties and whole stalk kraft pulp characteristics were combined, a plant population between 225 000 and 315 000 plants/ha, which is a little higher than that of kenaf bast production for textiles, was selected as the optimum cultivated kenaf plant population for whole stalk kraft pulp and papermaking on arid hillside land in China.
