摘　　要：本文以黄河三角洲盐碱地玉米为研究对象,利用黄河泥沙对盐碱地进行改良试验,分析不同黄河泥沙施用量和不同灌水量水平对玉米株高、叶面积、干物质量和产量的影响,探讨适宜的泥沙施用量和灌水量。结果表明,玉米的生长和产量都随着泥沙施用量和灌水量的增加而增大,且泥沙施用量均大于灌水量对其的影响;株高、叶面积指数、干物质量、产量均以泥沙施用量为6 cm、灌水量为150 mm处理最大,干物质积累量在成熟期最大为20460 kg/hm^2,夏玉米产量最大为11220 kg/hm^2。Taking corn in saline-alkali land of Yellow River Delta as research object,the saline-alkali land was improved by sediment of Yellow River,then the effects of different amount of sediment application and irrigation of Yellow River on plant height,leaf area,dry matter accumulation and yield of corn were analyzed to discuss the proper sediment application and irrigation amount.The results showed that the growth and yield of corn increased with the increasing of sediment application and irrigation amount,and the impacts of sediment application were greater than that of the irrigation amount.Plant height,leaf area index,dry matter accumulation and yield reached the maximum value under the treatment of sediment application amount of 6 cm and irrigation amount of 150 mm.The maximum dry matter accumulation was 20460 kg/hm^2 at mature stage,and the maximum yield of corn was 11220 kg/hm^2.
