目前,随着三熟制油菜的发展,全面要求油菜育苗移栽,是有一定困难的。特别是在田多劳力少的地区,由于季节紧、劳力不足、育苗移栽更难办到。近年来,我县三熟制油菜有新的发展,由原来3万来亩扩大到7万余亩,其中直播油菜比例占90%,主要是靠直播耒完成扩种计划的。那么,直播油菜能不能高产呢?我县三熟制油菜高产单位的生产实践证明,只要适时播种,加强管理,直播油菜同样能获得高产。如新滩公社农科所,去冬直播油菜78.3亩,收干籽18,173.4斤,油菜平均亩产232.1斤。又如县水稻原种场,近年来坚持四分之一(45亩)水田面积轮作直播油菜,油菜平均亩产110斤,高的亩产达207斤,稻油三熟两季水稻亩产超千
At present, with the development of the three-cropping rapeseed, it is quite difficult to fully require the rapeseed seedling transplanting. Especially in areas where there is less labor and labor, it is more difficult to transplanting nursery seedlings due to tight seasons and insufficient labor. In recent years, there has been a new development in Sanxian system of rapeseed in our county, from 30,000 mu to 70,000 mu, of which live rapeseed accounts for 90% of the total. So, can live rapeseed high yield it? Myeogo rapeseed production units proved that, as long as the timely sowing, strengthen management, live rapeseed can also get high yield. For example, Xintan Commune Agricultural Branch, 78.3 acres of winter rapeseed, dry seeds received 18,173.4 pounds, average yield of rapeseed 232.1 kg. Another example is the county rice seed field, in recent years, up to a quarter (45 acres) of paddy field area for direct seeding rapeseed, rapeseed average yield of 110 pounds, high yield of 207 kilograms of rice, rice, thousand
