| 摘 要： | 研究表明渗灌为棉株创造了良好的生长环境，促进了土壤团粒结构的形成，改善了土壤养分状况，铵态氮、硝态氮和速效磷等都有增加。渗灌田棉株体内蔗糖的含量远远高于漫灌田棉株。渗灌下的棉株生长稳健，根系发达，结铃多，产量增加２０％—３０％，比漫灌节约用水６０％。 |
| 关 键 词： | 棉花 渗灌 漫灌 |

| Abstract: | The results showed that infiltration irrigation promotes the formation of soil aggregated structure,increases the effective soil nutrients,including NII 4n itrogen and NO 3 nitrogen and phosphorus.The cotton plants under the infiltration irrigation,had a higher sucrose content and biomass,and more developed root system than that sucrose content and biomass,and more developed root system than that under flood irrigation,its bolls are larger,fibrious quality higher,and yield increases by 20%-30%,Therefore, infiltration irrigation can save 60% water than flood irrigation. |
