我们双江农场地处双江县勐勐坝区,海拔1045公尺,年平均温度19.4度,年雨量906毫米,全年有霜期为50天。我们于1977年和1978年连续两年把南优二号作双季早稻种植取得了显著的增产效果。1977年试种南优二号10亩平均亩产1097斤,比常规早稻品种每亩增产250—300斤。1978年进行连片示范种植南优二号80亩平均亩产1150—1200斤,亩产比常规品种增产300—350斤。高产的亩产突破1300斤,两年的实践证明,南优二号作双季晚稻栽种,有较高的丰产性能,是实现早稻低产变高产,高产再高产的一个重要途径。
Our Shuangjiang Farm is located in Meng Meng Dam, Shuangjiang County, at an elevation of 1,045 meters with an annual average temperature of 19.4 degrees and an annual rainfall of 906 millimeters with a frost-period of 50 days throughout the year. In 1977 and 1978 for two consecutive years, Nanyou No.2 for double crop early rice has achieved significant yield increase. In 1977, the test of Nanyou No. 2 10 mu average yield 1097 kg, than conventional rice varieties increased 250-300 pounds per mu. In 1978, a contiguous demonstration planting Nanyou 2 80 mu average mu produce 1150-1200 jin, mu produce 300-350 jin than conventional varieties. High yield per mu exceeded 1300 pounds, two years of practice has proved that the Nanyou No.2 for double season late rice planting, high yield performance, is to achieve low-yielding early rice high yield, high yield and then an important way.
