Effects of integration of irrigation and fertilization(drip fertigation) on growth, fiber yield and quality of kenaf
摘要
Abstract
Objective]The effects of integration of irrigation and fertilization (drip fertigation) on growth, fiber yield and quality were studied by using a field experiment to investigate utilization properties of water and fertilizer for kenaf , in order to provide references for high-yield and high-efficient cultivation of kenaf . [Method]Hybrid kenaf (Hibiscus cannabinus L.) cultivar Hongyou 2 was used as material, 6 treatments of drip fertigation and CK were de-signed in field experiment. Three treatments T1,T2 and T3 took 100% irrigation (12.947 m3) with 100%, 75% and 50% fertilization, respectively; treatments T4, T5 and T6 took 80% irrigation with 100%, 75% and 50% fertilization, respectively; CK took 100% irrigation (16.183 m3) using furrow irrigation and 100% fertilization (264.00 kgN/ha, 88 . 04 kgP2O5/ha , 176 . 09 kgK2O/ha ) using broadcast . [Result]The results showed that , compared with CK , six treatments T1, T2, T3, T4, T5 and T6 could significantly improve the growth and fiber quality of kenaf, the plant height , stem diameter , skin thickness , shoot dry mass , fiber yield and linear density were significantly increased by 13.2%-25.5%, 0.7%-1.4%, 10.6%-20.3%, 12.5%-30.9%, 15.1%-36.8% and 7.2%-30.7%, respectively. Out of six drip fertigation treatments , treatment T1 presented the best comprehensive effect , and followed by T5 and T2. Although the plant height, shoot dry mass, fiber yield and linear density of treatment T1 showed the highest, few sig-nificant differences were found as compared to treatment T5. The fiber strength of treatment T5 was higher than that of treatment T1 by using less irrigation and fertilizer. [Conclusion]As to drip fertigation of kenaf, treatment T5 (80% irri-gation:12.947 m3, and 75% fertilization:198.00 kgN/ha, 66.03 kgP2O5/ha, 132.07 kgK2O/ha) could obtain better water-and fertilizer-saving effects and should be recommended to apply in production.关键词
