研究了播期和密度对黄淮麦区弱春性小麦品种偃展4110籽粒灌浆特性的影响。结果表明：在不同播期或种植密度水平下，随着开花后天数的增加，偃展4110籽粒的千粒重均呈“S”型持续增加，其籽粒的灌浆速率均呈单峰曲线变化，在开花后20 d出现最高峰；适期早播和适当降低种植密度可以提高其籽粒的灌浆速率，增大粒重。

The effects of sowing date and planting density on the grain -filling characteristics of weak -springness wheat varie-ty Yanzhan 4110 in Huang-Huai area were studied .The results indicated that:at different sowing date or planting density levels , when the days after flowering increased , the 1000-grain weight of Yanzhan 4110 revealed a S-shape increasing trend , and its grain-filling rate showed a single -peak curve change with a peak on the 20th day after flowering;properly early sowing and appro-priately reducing planting density could enhance the grain -filling rate of this variety , and increase its grain weight.
