| The effects of irrigation and fertilization management on fiber yield and quality using a pot experiment were
studied to investigate the character of water and fertilizer use, so as to provide rational irrigation and fertilization for high yield and high efficient cultivation of kenaf. The results showed that: (1) In low fertilization, fiber yield, fiber length and width reached the maximums, and fiber strength and fiber line density had no significant reduction. (2) All NK fertilizer as base fertilization was beneficial to improve the fiber yield and linear density, while fiber strength did not reduce significantly. (3) Middle irrigation in seedling stage, high irrigation in vigorous growth stage and squaring and fruit stage,fiber yield, strength and length were higher than those of other treatments, and the fiber linear density did not decrease significantly. Therefore, the best strategy of irrigation and fertilization mode was low fertilization (N 0.15 g/kg soil, P2O5 0.075 g/kg soil and K2O 0.15 g/kg soil) with all NK fertilizer as base fertilization, and middle irrigation in seedling stage,high irrigation in vigorous growth stage and squaring and fruit stage. |
