为适应我区杂交水稻生产发展的需要,1982～1983年度,我们在海南繁殖不育系172亩,平均亩产120斤,其中珍汕97A86.7亩,平均亩产126斤,V41A85.3亩,平均亩产110斤。虽然海南今年天气反常,但仍超过我区历年南繁的单产量,并出现高产单位和珍汕97A平均亩产251斤、V41A平均亩产210斤的高产田块。这次南繁期间海南连续几个月阴雨连绵,气候反常,这是多年来最糟的早春天气。具体情况:一是气温低。从“大雪”起,连续6个节气气温低于常年均值;二是霜冻范围大。从湛江地区到海南中部都有霜冻;三是雨量多。2、3月份的降雨
In order to meet the needs of the development of hybrid rice production in our district, from 1982 to 1983, we breed 172 mu of CMS in Hainan with an average yield of 120 kg per mu, including 97A86.7 mu in Zhenshan, 126 mu on average, V41A85.3 mu , The average yield 110 pounds. Although Hainan weather is anomalous this year, it still surpassed the single production of Southern Fan in previous years in our region. High-yielding plots and yields of 251 kg per mu in Zhen Shan 97A and 210 kg per mu in V41A appeared. During this period, Hainan suffered from continuous rain and raging weather for months in a row during the Southern Fanzao period. This is the worst early spring weather in many years. Specific conditions: First, the temperature is low. From the “heavy snowfall”, six consecutive solarflood temperatures are below the annual average; second is the large frost range. From Zhanjiang area to central Hainan have frost; Third, more rainfall. February and March rainfall
