我县从1958年开始种植粳稻,当时少面积试种“老来青”,因对其种性和栽培技术掌握不好,结果失败了。1963年后,又从外地引进了“农垦58号”,“日本粳”、“科情三号”、“郴矮粳”,其中以“科情三号”和“郴矮粳”的面积较大,全县从1966年的500多亩,到1972年扩大到40000多亩,但当年由于对病虫防治不够及时,有一部分粳稻减了产,“科情三号”也因种性退化,面积逐年减少了,到1975年“郴矮粳”的面积仍保持3000多亩,主要在海拔400米以上的高寒山区种植,表现较 Since 1958, our county started to grow japonica rice. At that time, a small area was planted with “Lao Lai Qing”. Because of its poor understanding of the species and cultivation techniques, the result failed. After 1963, “Nongken 58”, “Japonica”, “Keqing 3” and “Chenchenjing” were imported from the field. The area of ​​“Keqing 3” and “Chenchenjing” Large, the county from 500 acres in 1966, expanded to 40,000 acres in 1972, but then due to inadequate control of pests and diseases in time, some of the reduced production of japonica rice, “Section No. 3” also due to degenerative species, The area has been reduced year by year. By 1975, the area of ​​Chenchenjing remained at 3000 mu, mainly planted in alpine areas at an altitude of 400 meters or above.
