我县油菜撒播育苗有三大缺点,一是播种不匀,露籽较多,出苗不齐,二是间苗费工,留苗稀密不匀,难以把住质量关;三是不利于中耕除草,不利于施肥和管理。为此:1983年我们改油菜撒播为条播育苗,收到较好效果:播种,出苗均匀;间苗每亩省工约5个以上;便于进行中耕除草,既控制了苗床草荒,又解决了雨后苗床土壤板结问题,育成的菜苗,大小基本均匀一致,苗体健壮。据调查,中、迟熟品种“广德761”,9月28日播种,11月10日移栽,行距4—4.5寸,每行留苗30—35棵(厢宽6尺)的条
I rape breed nursery in our county has three major shortcomings, one is uneven sowing, more seeds, seedling missing, the second seedling fee workers, seedling sparse uneven, it is difficult to live quality; Third, it is not conducive to cultivating weeds, Not conducive to fertilization and management. To this end: In 1983 we changed the rape sowing for the sowing nursery, received good results: sowing, emergence uniform; seedlings per acre province about 5 or more; easy to carry out weeding, not only control the seedbed shortage of grass, but also to solve the rain Seedbed soil compaction problem, bred vegetable seedlings, the size of the basic uniform, robust seedling body. According to the survey, medium and late maturing varieties “Guangde 761”, sown on September 28, November 10 transplanting, row spacing 4-4.5 inches, 30-135 per row of seedlings (car width 6 feet)
