摘要

一项研究比较了大粒和小粒小麦栽培品种在两种种植模式和两种灌溉制度下的籽粒饱满度和产量，结果表明，塑料覆盖的垄沟种植和喷灌提高了两种栽培品种的籽粒饱满度和产量。对籽粒产量贡献最大的是双大 1 号的籽粒充实期延长和 XN538 的平均籽粒充实率提高。

Grain-filling strategies of wheat of contrasting grain sizes under various planting patterns and irrigation levels

In a study comparing grain filling and yield in a large- and a small-grain-size wheat cultivar under two planting patterns and two irrigation regimes, plastic-covered ridge and furrow planting with sprinkler irrigation increased grain filling and yield in both cultivars. The largest contributors to grain yield were an extended active grain-filling period in Shuangda 1 and an increased mean grain-filling rate in XN538.
