摘要
根据贵州立体农业特点,结合不同海拔地区光温水生态条件,研究油菜丰产栽培配套技术。实现代培技术措施区域化、规范化的技术路线是:前期促秋发,中期稳健长,后期不早衰;或秋促发,冬稳健,春不衰。筛选适宜不同海拔地区(低、中、高)高产良种,严格掌握最佳播、栽期,移栽适龄壮苗,调节群体结构,合理配置密度,科学施肥,苗期早管促秋发,搭好丰产苗架等一系列配套技术措施。
According to the stero-agricultural characters of Guizhou,in the light of ecological conditions of illumination, temperature,and rainfall in different altitude areas, the study on high-yield cultivating technique of the rape was conducted.The technical line for region-alization and standardization of cultivating practice was summarized as that promoting growth at the earlier stage in Autumn, keeping steady growth in the middle stage and preventing early senility in the late stage were the principles of the rape cultivation,In other words,they were promoting growth in Autumn,steady growth in Winter,not decaying in Spring,So,it was suggested that a serial of techincal measures,as selecting high yield and good quality varieties suited separately for every altitude area, existing the optimum at its optimum date,translating the strong seeding age,adjusting the population struction,applying fertilizer scientifically,promoting seedling in earlier stage to keep growth well in Autumn was carried out,All of these provided the practical basis for bumper yield of the rape.
