摘　　要：通过小区试验表明,在干旱区沙地施用土壤保水剂,可保持较好的沙土墒情,支持地上部分茎叶生长发育;又能保证叶片蒸腾作用正常进行,改善作物体内水分生理状况。供试SUP型保水剂在浓度范围为0.1％～0.3％时处理效果显著,黄豆增产81％,玉米增产3％。应用土壤保水剂是干旱地区沙地农作物高效栽培的一种新途径。The plot experiments indicated that application of soil moisture mainten-er to sandy soil in the arid area can maintain good soil moisture, promote the growth anddevelopment of crop stems and leaves, ensure the normal evaporation of leaves and im-prove the water physiological conditions within crops. When the concentration range ofSUP-type soil moisture maintainer was between 0.1% and 0.3%, the treatmentshowed the significant results so that yield increase in soybean was 81% and that in cornwas 83%. Applying soil moisture maintainer is a kind of new way for highly-effectivecultivation of farm crops in sandy soil in the arid area.
