摘　　要：选用寒地早粳稻品种龙庆稻3号和空育131,以及早籼稻中早39在杭州3月1日播种,大棚育秧,18日移栽。通过黑龙江虎林(经度132.61°,纬度45.63°)和浙江杭州(经度119.94°,纬度30.08°)两地的2011-2018年的平均日气温、>10℃活动积温和2018年日光照时数等温光因子的比较,结合参试早稻生育期、产量及其构成和稻米品质,分析了寒地早粳稻在杭州地区双季早粳种植的适宜时期。讨论了长江中下游双季早稻“理想温光生态型粳稻”品种选育等问题,提出根据目标区域温光资源和寒地早粳稻温光特性相适宜的双季早粳稻引种策略。Early Japonica rice varieties Longqingdao 3,Kongyu 131 and Zhongzao 39 were sown on March 1 in greenhouse and transplanted on March 18 in Hangzhou.Based on the comparison of the average daily temperature,>10℃active accumulated temperature and sunshine hours in 2011-2018 between Hulin,Heilongjiang Province(longitude 132.61°and latitude 45.63°)and Hangzhou,Zhejiang Province(longitude 119.94°and latitude 30.08°),with the analysis of the growth period,yield and quality of early rice,the suitable period of double cropping early Japonica rice planting in Hangzhou was studied.According to the temperature-light resources in the target area and the suitable temperature-light characteristics for early Japonica rice in the cold region,the introduction strategy of double cropping early Japonica rice was put forward,and the breeding of“ideal temperature-light ecotype Japonica rice”in the middle and lower reaches of the Yangtze River was discussed.
