摘　　要：本研究对我国近年育成和主推的甘蔗新品种福农38号、福农39号，应用正交旋转组合设计，研究种植行距和下种量对两个甘蔗品种的产量影响。试验表明，种植行距对产量影响显著，在行距58～100cm范围内，产量随着行距的增加而降低，行距为100cm时产量最低，当行距大于100cm小于142cm时，产量又随着行距的增加而增加}下种量对福农38号影响不显著，对福农39号产量影响显著；种植行距和下种密度对产量的交互作用因甘蔗品种不同而异，福农38号的种植行距与下种量呈现负交互效应，福农39号的种植行距与下种量呈现正交互效应。By using combination design of orthogonal pivoting and quadratic regression equation, effects of different raw spacing and planting density on yield of sugarcane. Results showed, raw spacing is remarkable to the yield of sugarcane. The yield decreases with increasing raw spacing from 58cm to 100cm, and the yield increases with increasing spacing from 100cm to 142cm. The planting density had not a significant effect on yield of ＂Funong 38＂, had a significant effect on yield of ＂Funong 39＂, however. Raw spacing and planting density a negative had a negative interaction to ＂Funong 38＂, which had a positive interaction to ＂Funong 39＂.
