本研究探索了红麻品种、播种期、收获期、肥料和密度等因子对造纸用红麻干茎产量、质量的影响,结果表明:上述因子对红麻干茎产量与质量均有一定影响。如从4月30日至6月19日,每推迟10天播种,每亩减产干茎88.4公斤,且其细浆得率随之降低;从9月15日至10月15日,每推迟10天收获,每亩可增收干茎83～139公斤。研究还明确了每生产1吨红麻干茎需累积干物质1.288吨,需吸收 N13.2公斤、P_2O_53.402公斤、K_2O21.5公斤;在每亩留苗1～3万株范围内,红麻群体的增产作用大于麻株个体的增产作用。 In this study, the effects of kenaf varieties, sowing date, harvest time, fertilizer and density on the yield and quality of kenaf dried paper were studied. The results showed that the above factors had some effects on the yield and quality of dried kenaf. For example, from April 30 to June 19, every 10 days postponed for sowing, the dry stem yield per mu will be reduced by 88.4 kilograms, and the yield of fine pulp will decrease. From September 15 to October 15, every postponed 10 Harvest day, per acre can be increased dry stem 83 ~ 139 kg. The study also made it clear that for every ton of dry kenaf produced, it needs to accumulate 1.288 tons of dry matter and need to absorb N13.2 kg, P_2O_53.402 kg and K_2O21.5 kg; The effect of increasing the yield of hemp populations is greater than that of hemp plants.
