棉花产量由伏前桃、伏桃、早秋桃、晚秋桃组成,后期施桃肥,有利于多结早秋桃和晚秋桃。据试验,增施桃肥的棉花早秋桃、晚秋桃分别比对照多1.2和0.8个,棉株上部成铃数比对照多2.1个,伏桃、早秋桃和晚秋桃铃重分别比对照多0.1克、0.2克和0.18克,平均增产皮锦16公斤。桃肥追施因苗而定,一般掌握在8月初为宜,太晚易造成贪青晚熟。旺长棉田喷施500倍的磷酸二氢钾溶液2—3次促早衰,每亩每次喷70公斤左右,每隔7天喷一次,然后视苗情再喷施80倍尿素液70公斤。正常棉 Cotton yield from the volvae, V, peach, late autumn peach composition, post-peach fertilizer, is conducive to early knot autumn peach and late autumn peach. According to the experiment, bolls of early peach and late peach increased 1.2 and 0.8 more than the control, respectively. The number of bolls in the upper part of cotton was 2.1 more than the control, and the boll weight of peach, early autumn and late autumn were more than that of the control respectively Grams, 0.2 grams and 0.18 grams, an average of 16 kg increase leather. Peach fertilizer topdressing due to the seedlings, usually in early August is appropriate, too late to easily lead to late blooming. Wang Long cotton fields sprayed 500 times the potassium dihydrogen phosphate solution 2-3 times premature aging, per acre spray about 70 kg, spray once every 7 days, and then depending on the Miao Shi and then spray 80 times 70 kg of urea solution.
