摘　　要：针对引黄灌区水沙资源合理利用问题,文章开展了50m3/hm2、900m3/hm2、1050m3/hm2、1200m3/hm2灌水定额下的盐碱地改良试验。结果表明:通过引黄灌水对盐碱土壤进行改良,可有效减少粗粉粒含量占比,增加细砂粒、细分粒以及黏粒的占比;灌水定额越大,对泥沙入渗深度和土层颗粒级配的影响程度越大,改良效果也越好,土壤保水保肥性能越佳,越有利于农作物的生长。建议最佳灌水定额应根据当地农作物生长发育需水情况进行适当调配。The improvement experiments of saline-alkali land under the irrigation quota of 50m3/hm2,900m3/hm2,1050m3/hm2 and 1200m3/hm2 are carried out in the paper aiming at the rational utilization of water and sediment resources in the Yellow River Irrigation Area.The results show that the improvement of saline-alkali soil by irrigation from Yellow River could effectively reduce the content of coarse silt,and increase the proportion of fine sand,fine particle fraction and clay.The irrigation quota is larger,the influence on the sediment infiltration depth and soil layer grain composition is higher,the improvement effect is better,the soil moisture and fertilizer conservation performance is better,and the method is more conducive to the growth of crops.It is suggested that the best irrigation quota should be properly allocated according to the water demand for the growth and development of local crops.
