在毛主席革命路线指引下,在农业学大寨群众运动中,近年来我省大搞一年三熟多熟的耕作制改革,稻-稻-油菜这种耕作制在部分地区已逐步形成。各种种植油菜虽已积累一定经验,但产量不稳不高,其原因之一是油菜在生长发育过程中常会遇到不利的天气,如抽苔开花期的低温冻害,开花结荚期及收获期的连续阴雨等。为使油菜产量进一步提高,必须认真总结油莱高产的栽培经验,根据各地的气候特点,及各油菜品种的生长发育规律,因地制宜地采取有效措施. Under the guidance of Chairman Mao’s revolutionary line, in the Dalai Mass Movement for Agriculture, in recent years, the province has vigorously pursued the reform of the farming system that is well-versed and well-cooked in one year. The cultivation system of paddy-rice-rape has gradually taken shape in some areas. Although some rapeseed has accumulated some experience, but the yield is not stable, one of the reasons is that rape often encounter unfavorable weather in the growth and development process, such as bolting and flowering of low temperature freezing injury, flowering podding and harvest Continuous rain and so on. In order to further improve the yield of rapeseed, we must conscientiously sum up the high-yield cultivation experience of oilseed rape and take effective measures according to local conditions according to the climatic characteristics of each region and the growth and development rules of the rapeseed varieties.
