摘　　要：通过盆栽棉花实验探讨了草炭与制剂对棉花不同生育期养分 (N、P、K)吸收的影响。实验结果表明 ,草炭与制剂可以促进养分的吸收利用与合理分配。在棉花苗期 ,草炭与制剂处理的氮素积累量分别是对照的 1.2 - 2倍和 2 - 3倍。草炭处理的苗期棉花磷素积累量是对照的 1.5 - 4倍 ,制剂是 3 - 6.5倍。草炭处理的在苗期钾素积累总量是对照的 1.5 - 2 .5倍 ,而制剂是对照的 2 .5 - 3 .5倍。草炭与制剂处理的棉花吸收的营养能及时转移到生长旺盛的部位 ,加速植物的新陈代谢和物质合成 ,为棉花的丰产奠定了基础。This paper discusses the effect of peat composed of rotten mosses and its preparation on the nutrient assimilation and distribution of potted cotton in its different growing stages. The experimental results show that peat composed of rotton mosses and its preparation can promote the assimilation, utilization and rational distribution of nutrient (N,P and K). In the seedling stage of cotton,the accumulated quantities of N-nutrient, P-nutrient and K-nutrient in the pots where peat composed of rotton mosses and its preparation are spread are 1.2～2 and 2～3, 1.5～4 and 3～6.5, and 1.5～2.5 and 2.5～3.5 times of those of the contrast ones respectively. The nutrient assimilated by cotton treated by peat composed of rotten mosses and its preparation can be timely transferred to the luxuriantly-growing positions of cotton, which speeds up the metabolism and material composition and plays a foundation for getting bumper crop of cotton.
