The main results were as follows: number of available cotton bolls were strongly correlated with N rates, and shedding rates of buds and bolls were negatively correlated with N rates; abundant nitrogen nutrition were the necessary condition to increase available bolls and decrease shedding rate; applying nitrogen fertilizer prolonged the duration of cotton bolling increase and.
结果表明:有效棉铃数量与氮肥施用量密切相关,蕾铃脱落率与氮肥施用量呈显著负相关,充足的氮素营养是增加有效铃数和降低脱落率的必要条件;施用氮肥延长棉铃增长的时间,并相对滞后脱落率上升的趋势;施用氮肥增加了棉株各个部位的有效铃数,尤其提高了中下部果枝上有效铃所占比重,同时施用氮肥降低了中下部果枝上的蕾铃脱落率。
6) high falling off rate
