摘要
以库托河灌区为试验区域,分析气候资源的动态变化对大田棉花膜下滴灌种植参数的影响。通过对三种方案土壤润湿体形态、作物生长、作物产量和品质等进行比照,结果表明:毛管间距120cm就能基本满足外行棉花植株生长所需的水分,毛管间距120cm外行的水分等生长条件最为适宜,棉花产量最高,品质最优,应大力推广应用。结果可为库托河灌区农业气候资源利用效率的提升和作物产量的提高提供借鉴指导。
Taking the Cotto River irrigation area as a test area,the article analyzes the influence of dynamic changes of climate resources on the planting parameters of Datian cotton under drip irrigation.By comparing the soil wetting body morphology,crop growth,crop yield and quality of the three schemes,the results show that the capillary spacing of 120 cm can basically meet the water required for the growth of the outer cotton plant,and the growth conditions of the capillary spacing of 120 cm.Most suitable,cotton yield is the highest,the quality is the best,should be promoted and applied.The results can provide reference for the improvement of agricultural climate resource utilization efficiency and crop yield in the Cotto River irrigation area.
