摘  要:
试验用酒精废液水肥技术对甘蔗水分利用效率的影响,分析了影响甘蔗水分利用效率的生理因素。结果表明,甘蔗单叶水分利用效率水分处理间存在着显著差异,试验得出最优的水肥搭配水平是A3B1C3D2(高氮+低磷+高钾+中水),适中的水肥搭配水平能使甘蔗达到较高水分利用效率。

摘  要:
This investigation studies the influence of the water and fertilizer technique of alcohol wastewater to the water use efficiency of sugarcane. Analyzes the influence of physiological factors of sugarcane's water use efficiency.The data result showed that there were significant differences among water treatments of sugarcane's water use efficiency of simple leaf. The result showed that the best water and fertilizer levels is A3B1C3D2(high N+low P+high K+medium level water).The sugarcane can get a higher water use efficiency under the circumstance of moderate water and fertilizer coupling.
