摘要
2005年唐海县种植的津粳杂2号结实率存在不同程度的降低,通过调查表明:唐海县8月10～16日的高温天气与津粳杂2号等品种的不实率密切相关。可通过筛选对高低温耐受力强的品种、改进田间管理、提倡辅助授粉等措施预防水稻高温热害。
Through the investigation on the low kernel set of Jinjingza No. 2, a hybrid rice, at. Tanghai County in 2005, the result showed that the low kernel set of Jinjingza No.2 had close correlations with high temperature between 10th and 16th in August. The high temperature damage could be prevented by the usage of varieties with strong high temperature resistance and by the improvement of management and supplementary pollination.
