栽培技術對甘藷品種光合產物生產及分配影響

Abstract

本試驗採用裂區設計，以灌溉及無灌溉為主區，品種、氮、及鉀肥料用量及種植密度等之組合處理為副區，於秋作進行田間試驗，以供探討對甘藷在各生育期中植株各部份光合產物生產及分配之影響，及其與生理特性及收量之關係。 In order to investigate the effects of cultural practices on dry matter production, partition, physiological characteristics and yield of sweet potato at different growing stages, a field experiment was conducted at fall season. Split-plot design was adopted with irrigation as main plot and the combination of cultivar, fertilizer and population density as sub-plots.
