摘　　要：黄河泥沙施用量和灌水量对黄河三角洲盐碱地冬小麦生长发育和产量的影响进行了大田试验,探讨了不同泥沙施用量和灌水量与冬小麦的株高、分蘖数、叶面积、干物质积累量与产量之间的关系。结果表明,冬小麦的生长和产量都随着泥沙施用量和灌水量的增加而增大,泥沙施用量的影响均大于灌水量。泥沙施用量和灌水量在拔节期以后对冬小麦株高影响较大。6 cm泥沙施用量、330 mm灌水量处理的叶面积指数、灌水量和产量最高,叶面积指数在抽穗期达到最大(6.89);干物质积累量在成熟期最大(13620 kg/hm^2);冬小麦产量最为5556.3 kg/hm^2。Field research was carried out on the effects of sediment application dosage and irrigation amount in the Yellow River on the growth and yield of winter wheat in saline-alkali soil of Yellow River Delta.Relationship between the sediment application dosage and irrigation amount on the plant height,leaf area,tiller number,dry matter accumulation and yield of winter wheat were discussed.Results showed that the growth and yield of winter wheat increased with the enhancement of sediment application dosage and irrigation amount;and the impacts of sediment application dosage were greater than the irrigation amount.The two factors showed greater impacts on the plant height of winter wheat after jointing stage.Treatment of 6 cm sediment application dosage and 330 mm irrigation amount had the maximum yield,leaf area index and irrigation amount.Leaf area index reached the maximum at heading stage(6.89);dry matter accumulation was the maximum at mature stage(13620 kg/hm ^2),and the maximum yield of winter wheat was 5556.3 kg/hm^ 2.
