摘要:
[目的] 探讨一次性施用甘蔗专用缓释肥对宿根蔗生长、产量和品质的影响,为降低宿根蔗施肥成本提供参考。[方法] 设置一次性施用甘蔗专用缓释肥、一次性施用常规肥、常规施肥及不施肥(CK)4种处理,调查各处理宿根蔗的农艺性状、品质性状和蔗茎产量,并比较其经济效益。[结果] 一次性施用甘蔗专用缓释肥的宿根蔗产量显著高于一次性施用常规肥和CK,与常规施肥相当;分别比CK、一次性施用常规肥、常规施肥增收8 671.1、 5 118.5、1 749.2元·hm-2[结论] 宿根蔗一次性施用甘蔗专用缓释肥可减少化肥施用量,降低生产成本,提高经济效益。
Abstract:
[Purpose] To study the effects of one-time application of sugarcane special slow-release fertilizer on the growth, yield and quality of ratoon sugarcane and to provide a reference for reducing the fertilization cost of ratoon sugarcane.[Method] A field experiment of one-time application of sugarcane special slow-release fertilizer, one-time application of conventional fertilizer, conventional fertilization, and no fertilization (CK) was conducted on ratoon sugarcane. Agronomic traits, quality characteristics, cane yield were investigated and economy efficacies were compared.[Result] The yield of ratoon sugarcane with one-time application of special slow-release fertilizer was significantly higher than that of one-time application of conventional fertilizer and the CK, but was equivalent to the yield of conventional fertilization. Comparing to no fertilizer application, one-time application of conventional fertilizer, and conventional fertilization, the income with one-time application of special slow-release fertilizer increased by 8 671.1, 5 118.5, and 1 749.2 yuan·hm-2, respectively.[Conclusion] The one-time application of sugarcane special slow-release fertilizer on ratoon sugarcane can reduce the amount of chemical fertilizer, reduce production cost, and increase economic benefit.
