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
Effects of Sowing Date and Planting Density on Grain-filling Characteristics of Weak-springness Wheat Variety in Huang-Huai Area
摘要
Abstract
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.关键词
