| 摘 要： | 通过对不同施肥水平下杂交棉泗阳329的生物学特性及生理机制研究发现,在氮肥施用量为20 kg/667m2、钾肥施用量为25 kg/667m2时,果枝始节位最低,果枝台数最多,有利于早发及果枝形成。在此条件下,叶面指数、功能叶光合速率、现蕾数、现蕾强度、单株成铃、成铃强度均较高,这是其高成铃和提高产量的基础。在生产上应用此肥料运筹模式,有利于实现该品种高产高效,并充分发挥其增产作用。 |

| Abstract: | Biological characteristics and physiological mechanism of hybrid cotton Siyang 329 in different fertilizer application were studied.The experimental result indicated that applying 300 kg/hm2 of N and 375 kg/hm2 of K2O was the best for the Siyang 329.It lowered newborn position of fruit branch,increased fruit-bearing branch number,and promoted early development and fruit branch formation.In this situation,leaf-area index,functional leaf photosynthetic rate,flower buds number,budding power,boll number per plant and boll setting intensity of the Siyang 329 were high,which could increase total boll setting and yield.So this fertilization model could apply in practical production for higher output and efficiency. |
