我县山区海拔较高,春季阴雨天多,低温寒潮频繁,秋后寒流一般在8月中下旬即可到来。杂交中稻在这些地方栽培,春季烂秧严重,秋后易受寒露风危害。造成产量不稳不高。为了克服低温给杂交中稻生产带来的严重影响,1982—1983年,我们对山区种植杂交中稻的育秧方式进行了研究,试图在提
My county mountain area is higher elevation, cloudy and rainy days in spring, cold frequent cold, autumn cold usually come in late August. Hybrid mid-season rice is cultivated in these areas, with severe rotten seedlings in the spring and easily exposed to cold and wind devastation in autumn. Resulting in unstable output is not high. In order to overcome the serious impact of low temperature on the production of hybrid mid-rice, we conducted a study on the cultivation methods of mid-season hybrid rice in mountainous area in 1982-1983,
