在云南高原的山间盆地,分布着大面积的高原水稻。其栽培历史,有记载的竟长达三千余年。近年来,由于气候的有利变化,和栽培技术的提高,水稻不断获得高产:出现了平均亩产上千斤的县(面积十余万亩);1982年,大理县(海拔1991米)三万亩“滇榆一号”平均亩产1300斤,最高达1887.79斤,夺国内粳稻单产之冠;宾川县(海拔1438米)的“桂朝二号”平均亩产2111.5斤,超过我国杂交稻的最高单产,创国内一季稻单产最高纪录。
In the mountain basin of the Yunnan Plateau, a large area of plateau rice is distributed. Its cultivation history, there are actually recorded up to 3,000 years. In recent years, due to the favorable climate change and the improvement of cultivation techniques, rice has been continuously producing high yields: there have been counties (area more than 100,000 mu) with an average yield of thousands of kilograms; in 1982, Dali County (1991 meters above sea level) “Dianmu One” average yield of 1300 pounds, up to 1887.79 pounds, won the highest domestic production of japonica rice; Binchuan County (1438 meters above sea level) “Guichao II” average yield of 2111.5 kg, more than China’s hybrid rice The highest yield, creating a record high season of domestic rice.
