摘要: 本文具体分析了京双14号稳产600~800斤/亩的原因:抗寒、越冬分蘖存活率高,保证亩穗数较多(30~32万/亩)且稳;冬性一般,穗分化在返青后开始并持续时间不长,形成小穗数中等、勾三小穗较多的穗型,保证其既有较多的穗粒数(30~32粒),又避免不抗寒和晚熟;灌浆快,抗倒(株高85~90厘米),抗病(兼抗条、叶锈和白粉),确保千粒重较高且

Abstract: Factors of stable yield ranging from 600-800 jins per mu of “Jing-shuang 14”were analysed as follows:cold resistance with a high survivalrate of overwintering tillers resulting 300,000-320,000 spikes per mu;amedium differentiation period of spikelet after turn green maintaining amedium number of s
