播期和密度对黄淮麦区弱春性小麦品种籽粒灌浆特性的影响

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 variety 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 appropriately reducing planting density could enhance the grain - filling rate of this variety,
