星星农科所是我县出席全国科学大会的先进单位。近几年来,每年种植红苕25—30亩,年年获得高产。1973年、1974年平均亩产都在4,500斤左右;1975年平均亩产9,245斤,其中4亩高产试验田亩产达到12,000斤。最近两年虽然遭受到春寒、冰雹、干旱、洪涝等自然灾害,但是亩产仍达8,000余斤。他们种植红苕获得连年高产稳产的技术措施,除选用红苕良种“67—12”、丰薯 Star Academy of Agricultural Sciences is my county to attend the National Science Conference advanced unit. In recent years, 25-30 mu of red crab is planted every year and high yield is achieved every year. In 1973 and 1974, the average yield per mu was around 4,500 kilograms. In 1975, the average yield per mu was 9,245 kilograms, of which 4 mu of high-yielding trial land had a yield of 12,000 kilos. Despite the natural disasters such as spring cold, hail, drought and floods in recent two years, the output per mu still amounts to more than 8,000 kilos. They planted red crabs to obtain successive years of high and stable technical measures, in addition to the selection of red crab varieties “67-12”,
