本文用培矮64s-05在三亚南繁时的逐日自交结实率资料和逐日均温和日长资料,根据育性量化模型鉴定该不育系在三亚的育性指标,并对培矮64s-05的光温反应特性进行分析。结合三亚30年(1959～19S8年)逐日气象资料和生育期预测模型对培矮64s-05南繁的最佳抽穗期和最佳播种期进行气候决策。
In this paper, Pei’ai 64s-05 was used to determine the fertility index of SJ in Sanya according to fertility quantification model. The data of Pei’ai 64s- 05 light and temperature response characteristics were analyzed. Based on the daily meteorological data of 30 years (1959 ~ 19S8) and the prediction model of growth period in Sanya, the climate decision was made on the optimum heading date and the optimum sowing date of Pei’ai 64s-05 Nan Fan.
