我县油菜栽培制度过去主要是中稻——油菜,一年两熟制。近年来,随着水稻的改制,双季稻大大发展,因而早茬油菜大大的缩小了。1964年全县播种油菜3万多亩,早茬(中稻、一晚)油菜面积占全县油菜播种总面积的35.5％,而迟茬则占64.5％。油菜栽培制度改革后,同样获得了油菜的增产丰收。全县油菜平均亩产93斤,比1964年亩产76斤增长26.3％。同时出现很多高额丰产的典型大队、生产队及丰产田。 1965年油菜的增产丰收,为我县进一 Rape cultivation system in our county in the past mainly in the rice - rape, cooked twice a year. In recent years, with the restructuring of rice, double crop rice has greatly developed, so early crop rape greatly reduced. In 1964 the county planted more than 30,000 acres of rapeseed, early crop (middle rice, one night) rapeseed crop area accounted for 35.5% of the total area planted, while stubble accounted for 64.5%. Rape cultivation system reform, the same access to the rapeseed yield increase. The county average yield of rapeseed 93 pounds, 76 pounds more than in 1964, an increase of 26.3%. At the same time there are many high-yielding typical brigade, production team and high yield fields. Rape yield increase in 1965, into one for my county
