| 摘 要： | 为改善果蔗施肥技术、提高果蔗种植的经济效益和环境效益,开展了国产控释配方肥、脲醛缓释复合肥和进口复合肥在果蔗上应用的大田试验。结果表明,果蔗栽培中施用缓/控释配方肥料较施用进口复合肥的产量和总生物量分别提高了1.8%~5.7%和5.7%~15.5%。与进口复合肥相比,缓/控释配方肥料成本更低,施用控释配方肥和脲醛复合肥每公顷增收11 144~17 147元和20 835~23 037元。此外,施用控释配方肥可以显著提高果蔗的NAE、NPF及NUE,提高果蔗氮肥利用效率。果蔗栽培过程中合理地施用缓/控释配方肥料能促进果蔗增产、增收、提高肥料利用率。缓/控释配方肥料可以取代进口复合肥为果蔗生长提供养分,实现轻简施肥。

| Abstract: | In order to improve fertilization technology, enhance economic returns and environmental benefits of chewing cane production, a field experiment about buck blended controlled fertilizer(BBCRF)and urea formaldehyde incorporated compound fertilizer(UCF)application were conducted in this study. The results showed that the cane yield and biomass of slow/controlled release fertilizer treatments increased by 1.8%-5.7% and 5.7%-15.5% comparing with import compound fertilizer(ICF)treatments. Compared with ICF treatments, the cost of slow/controlled release fertilizer was lower, and BBCRF and UCF treatments enhanced economic returns by 11 144-17 147 yuan and 20 835-23 037 yuan per hectare respectively. In addition, the application of BBCRF significantly increased nitrogen agronomic efficiency, nitrogen partial factor productivity and nitrogen use efficiency. Appling slow/controlled release fertilizer rationally could increase cane yield, total biomass, economic returns and nitrogen use efficiency in chewing cane plantation. Slow/controlled release fertilizer could replace import compound fertilizer to provide nutrients for chewing cane and achieve labor saving fertilization. |
