摘　　要：１９９４～１９９５年在陕西关中西部棉区选用中熟品种中棉所１２，研究了不同施肥情况下棉铃的发育规律及氮、磷、钾肥在纤维、棉子和铃壳动态发育过程中对棉铃体积增大和各部分干物质积累的影响。研究表明：氮可明显促进棉铃体积增大和棉子蛋白质含量提高，磷、钾能促使光合产物的转运，有利于纤维中纤维素的积累和种子油分含量的增加。During the two years in 1994￣1995, field experiments were studied with the medium maturing cotton (Gossypium hisutum L.)cultivar 'CCRI 12', aiming to determine the effects of different fertilizer applying treatments (N,P,K,NPK and no fertilizer) on the dynamic development of boll, boll shell, fiber and seed of cotton .The results showed as follows: cotton bolls volume and protein content in seed were significantly increased by nitrogen application. Cellulose synthesis, seed kernel oil content and the transportation of dry matter were promoted by phosphorus and potassium application.
