| 摘 要： | 氮肥随水施用可显著提高棉花单株铃数、单铃重和籽棉产量,促进棉花对氮、磷素的吸收,尤其在壤土棉田的效果较明显。随水施用磷肥对棉花单株铃数影响不大,籽棉产量较不施磷肥处理提高8.80～17.40%,其在壤土棉田上的增产效果优于粘土棉田。磷肥随水滴施可提高氮、磷肥料利用率,与基施相比氮肥利用率提高4.85～12.34%,磷肥利用率提高36.75～45.88%,且在壤土棉田上的施用效果优于粘土棉田。 |

| Abstract: | Single boll weight, boll number per plant, yield and the cotton's absorption of nitrogen and phosphorous were promoted by using nitrogen fertilizer dissolved in water, especially in loam soil.The yield of seed cotton increased by 8.80-17.40 percent in the phosphate treament than no-phosphate fertilizer treatment, and the production of the seed cotton in loam soil was better than that in clay soil. The N and P fertilizers applied by drip irrigation increased yled by 4.85-12.34 and 36.75-45.88 percent respectively compared with basal application. |
| Keywords: | Under-mulch-drip irrigation Cotton Nitrogen fertilizer Phosphate fertilizer |
