| 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 by 17.1%, 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. |
