【摘要】 陆稻“秦爱”,在北京,天津地区多作麦茬种植,为充分发挥其生产潜力,对陆稻“秦爱”、“冀粳7号”进行了分期播种对比试验。由于各播期所受光温条件的差异,使粒重随播期而发生变化。“秦爱”的最佳播期比麦茬种植要提早10～20天。为此,建议“秦爱”在作麦茬种植时,应安排在早熟麦地块,尽量提早播种期。更多还原

【Abstract】 Bring productive potentiality intofull play of upland rice variety“QinAi”seeding on unfallowing field of wheatin Beijing and Tianjing area.The diff-erent seeding time experiment of “QinAi”and“Ji Geng No. 7”was goneon.As result to variant grain weightwith seeding time because there are di-fferent light and temperature in diffe-rent seeding time,since the optimumseeding time is earlier 10-20 days thanthe seeding time of unfallowing fieldof wheat.We suggested that the“QinAi”are seeded on unfallowing field ofearly maturity wheat.更多还原
