摘　　要：以常规红麻常规栽培种福红992为试材,设免耕(A)、垄耕(B)、深松耕(粉垄,C)3种耕作方式与T1(20%作基肥,80%作追肥)、T2(40%作基肥,60%作追肥)、T3(60%作基肥,40%作追肥)3种施氮方式共9个处理,分别为AT1、AT2、AT3、BT1、BT2、BT3、CT1、CT2、CT3,探讨不同耕作和施氮方式对红麻产量和纤维品质的影响,为红麻高产高效栽培提供合理的耕作和施肥依据。结果表明:(1)深松耕的耕作方式与20%作基肥、80%作追肥的施氮方式互作时,红麻的纤维产量和种子产量均达到最大值;(2)与免耕相比,深松耕的纤维产量、种子产量和纤维强力分别增加17.0%、14.8%和18.4%,线密度降低15.9%,深松耕可显著提高红麻产量和纤维品质;(3)与T1相比,T2的纤维产量、种子产量和纤维强力分别增加17.1%、30.8%和17.6%,线密度降低17.3%,适当增加氮基肥的比例可以增加红麻的产量和纤维品质。因此,采用深松耕结合20%N肥作基肥,福红992的纤维产量最高,同时兼收的种子质量也达到最大值。The fiber yield and quality of regular cultivation kenaf（Hibiscus cannabinus L.）, Fuhong 992, were determined under three tillage methods（no tillage, ridge tillage and sub-soiling tillage）, three nitrogen fertilizing methods（T1： 20% N fertilizer as basal fertilizer; T2： 40% N fertilizer as basal fertilizer; T3： 60% N fertilizer as basal fertilizer）. The effects of tillage and N fertilization methods on fiber yield and quality using a field experiment were studied to provide a sensible solution for high yield and high efficient cultivation of kenaf. Results showed that,（1） the yield of fiber and seed reached the maximum when 20% N fertilizer was as base fertilizer and 80% was as top dressing deep tillage farming methods.（2） Compared with no tillage, the yield of fiber and seed, fiber strength increased by 17.0%, 14.8% and 18.4%,while line density decreased by 15.9%.（3） Compared with T1, the yield of fiber and seeds, fiber strength of T2 increased by17.1%, 30.8% and 17.6%, while line density decreased by 17.3%. Therefore, fibers yield of Fuhong 992 could get the highest at deep tillage combined with 20%N fertilizer as basal fertilizer, and the yield of seed could reach the maximum,too.
