自1973年以来,我所围绕着水田三熟油菜高产栽培技术搞了二十多项试验,进行了系统的总结和研究,为长江中游地区提供了“一大(大壮苗移栽)、二早(早播早栽)、三高(高水平的管理)、四巧(巧施肥,重施年前肥)、冬发(油菜苗12月下旬达到10片叶,尺把高、尺把长,墩墩棵封了行的长相)促春发,双发夺高产的高产栽培技术措施。在生产上应用的实践表明,增产效果非常显著。广济县推广该技术后,四年来油菜面积从5.9万亩发 Since 1973, I have conducted more than twenty experiments around the high yielding cultivation techniques of the three ripening varieties of paddy field in paddy fields, and have systematically summarized and studied them, providing "one big (big strong seedling transplanting) for the middle reaches of the Yangtze River, Early (early sowing early), three high (high level management), four clever (clever fertilization, heavy re-fertilization years ago), winter hair (rape seedlings in late December to reach 10 leaves, , Pier stamped the line appearance) spring hair, double yielding high yielding high yield cultivation techniques and measures in the production of practical application shows that the yield is very significant.Guangji County to promote the technology, rapeseed area in four years from 5.9 acres of hair
