| 摘 要： | 试验研究高光效空心多茎株型短季棉施N效应结果表明 ,强源是空心多茎株型短季棉施N增产的主要原因 ,扩库对产量的作用有限。低N量即显著提高空心多茎株型短季棉皮棉产量 ,继续增施N肥则空心多茎株型短季棉仅对N素表现出较强适应性 ,而未能充分发挥其产量潜力 ,表明产量潜力的发挥需要配套栽培技术的支撑

| Abstract: | Effects of application of nitrogenous fertilizer on the short dated cotton of top removal planting type with high photosynthetic show that the buildup fountain is the main reason of increasing production, enlarging storeroom is the limitation to production. A less nitrogenous fertilizer can improve the lint cotton yield remarkably, more nitrogenous fertilizer only makes cotton improving its adaptability, but not extra yield remarkably. The yield potential depends on a suit of planting techniques. |
