海南引种粳稻及生产试验

Japonica Introduction and Production Experiments in Hainan Province

从黑龙江、江苏、浙江和天津等省市引进405个粳稻品种在海南试种,经过2年筛选,获得3个对热带气候适应性较强的粳稻,表现出产量较高、抗性较强、米质优的特点。对入选粳稻进行小面积生产试验并提出海南引种粳稻的原则和栽培技术建议。

3 varieties were screened out from 405 japonica materials introduced from Heilongjiang, Jiangsu, Zhejiang Provinces and Tianjin City by introduction testing in Hainan Province for 2 years. They showed relatively high yield, strong disease resistance and good grain quality. The production experiments on the 3 screened japonicas in small area were done, also. The principles for japonica introduction and the suggestions on cultivation technique in Hainan province were proposed.
