江苏地少人多,粮、油、棉、饲争地矛盾突出,主攻单产,提高经济效益是发展生产的重要指导思想。为了探讨我省油菜高产经济栽培规律,1984～1987三个生产年度,我们对油菜栽培的几个关键因素在全省范围内进行了多因素、多水平、多指标的系统研究。试验按自然区划,设在淮北的睢宁、淮安,里下河的高邮、兴化,沿江沿海的泰兴、邗江、盐城农校,丘陵山区的句容,太湖地区的吴县、吴江等10多个点上。试验资料通过微机计算分析,优选出适合不同地区和不同自然条件栽培的综合农艺方案。研究结
There are many people in less places in Jiangsu Province, with prominent contradictions in the areas of grain, oil, cotton and cotton farming. The main production targets are major ones and the economic benefit is an important guiding principle in the development of production. In order to explore the law of high-yield economic cultivation of rapeseed in our province from 1984 to 1987, we conducted a systematic study of several key factors of rape cultivation in the province in a multi-factor, multi-level and multi-index. According to the natural divisions, the experiments were conducted in Huaian, Huaian and Gaixia of Lixiahe, Xinghua, Taixing, Qijiang and Yancheng Agricultural Schools along the Yangtze River, Jurong in the hilly and mountainous areas, Wuxian and Wujiang in the Taihu Lake region Point. Experimental data through computer analysis, optimization for different regions and different natural conditions of the integrated agronomy program. Study Results
