温泉是一个宝贵的天然地热场。我国温泉资源十分丰富,冬季利用温泉的热能种植晚稻杂种和移栽水稻花培绿苗,可以实现晚稻一年二熟和提高花培绿苗成活率,是加速水稻育种进程的一个经济有效途径。自1970年以来,我所先后三次在地处北纬25.1°,海拔330米的上杭进行温泉冬繁试验,取得良好的结果。现简介于下。 Spa is a precious natural geothermal field. The hot spring resources in our country are very rich. In winter, it is an economical and effective way to accelerate the process of rice breeding by using hot spring thermal energy to plant late rice hybrids and transplanting rice flower green seedlings, which can achieve double cropping in late rice in one year and increase the survival rate of green seedling. Since 1970, we have conducted winter hot spring trials at Shanghang, located at 25.1 ° north latitude and 330 meters above sea level, with good results. Now brief below.
