| 摘 要： | 试验以棉花品种沧198为材料，以常规植棉为对照，在旱碱地条件下研究了微沟覆膜植棉（开15 cm深的浅沟，地膜覆盖，膜上打孔种植）对棉花根际土壤水分、电导率，对出苗、成苗、棉苗素质及某些生理特征的影响。结果表明，与常规植棉相比，微沟覆膜棉花苗期根际土壤含水量显著提高，土壤电导率显著降低；微沟覆膜的出苗率提高了12%，现蕾期棉株株高、茎粗、干物质质量分别提高了10.5%、6.9%、8.9%，主茎功能叶SOD、POD活性、脯氨酸含量分别降低了13.7%、18.0%、11.7%；微沟覆膜棉花的单铃重与产量分别提高了7.3%、8.1%；微沟覆膜通过集雨压盐，改善了棉花根际环境，增强了棉苗素质，从而提高产量。

| Abstract: | Using the Cang 198 cultivar, with the traditional planting model as a control, we conducted field experiments to study the ecological and biological effects of the micro-ditch and overbite-membrane planting model(micro-ditch of 15 cm, plastic film mulching, sowing through holes perforated in the film) in Cangzhou saline fields. We studied soil volumetric water content and electrical conductivity, the percentages of seedling emergence and survival, the quality of the seedling environment and seedling physiological characteristics. The results indicated that soil volumetric water content under the micro-ditch and overbite-membrane planting model was significantly increased and soil electrical conductivity was significantly decreased compared to the traditional planting model. In the budding period, plant height, stem diameter and dry matter under the micro-ditch and overbite-membrane planting model were increased by 10.50%, 6.90%, 8.91%, respectively, compared to the traditional model, while SOD, POD activity and the proline content of functional leaves were reduced by 13.7%, 18.0%, and 11.7%, respectively,. Boll weight and yield increased by 7.34% and 8.07%. It can be concluded that the micro-ditch and overbite-membrane model collected rainwater and reduced salt, enhancing the quality of the seedling environment. Therefore the micro-ditch and overbite-membrane planting model can increase yield. |
