摘　　要：以3种筋力型冬小麦品种为试材,研究其在不同土壤质地上,池栽条件下淀粉的积累动态。结果表明:壤土上淀粉积累速率最大,粘土上次之,砂土上最小。不同土壤质地强筋品种淀粉积累呈不规则抛物线趋势,但差异不大;中筋品种在不同土壤质地上积累动态呈不规则抛物线,其中,在壤土上淀粉积累量最大;弱筋品种在不同土壤上淀粉积累均呈抛物线型,在壤土上淀粉积累量最大。Pool experiment was carried out to study the starch accumulation of three winter wheat cultivars with different gluten strength in three different soil textures. The main results were as follows.based on the starch accumulation rate of the tested wheat cultivars, three different soil textures were arranged in the order of loam〉clay〉sandy. The starch accumulating quantity of all the tested cultivars showed irregular parabola types in difference soils; the strong gluten cultivar did not reach a notable level in different soils, both middle gluten cultivar and weak gluten cultivar gave the largest in the loam soil based on the starch accumulating quantity.
