我市地处长江三角洲中部,常年油菜种植面积8万亩左右。1995年以前,我市油菜栽培以育苗移栽方式为主,与小麦生产相比,用工较多,效益不高,在一定程度上限制了油菜的发展。随着农业结构的调整,小麦价格的进一步下挫,油菜种植面积明显扩大,稻田套播油菜栽培应孕而生。从1998年起,我们对稻套油配套栽培技术进行了较为全面的研究与示范应用,取得了理想的效果。1999年示范试验表明,与常规移栽油菜相比,稻套油667m~2165.2kg,667m~2增产13.9％,且667m~2节省育苗与移栽用
The city is located in the middle of the Yangtze River Delta, perennial planting area of about 80000 rapeseed. Before 1995, the rapeseed cultivation in our city was dominated by seedling transplanting. Compared with wheat production, more labor was employed and the benefit was not high, which limited the development of rapeseed to a certain extent. With the adjustment of agricultural structure, wheat prices fell further, rapeseed area apparently expanded, the intercropping rape cultivation should be born. Since 1998, we have carried out a more comprehensive research and demonstration application on rice cultivation techniques and achieved satisfactory results. The demonstration experiment in 1999 showed that compared with the conventional transplanting rapeseed, the yield of 667m ~ 2165.2kg and 667m ~ 2 of rice hull oil increased by 13.9%, and the saving of seedling and transplanting with 667m ~ 2
