油菜是泰县的主要油料作物。近年来,随着种植业结构的调整,油菜面积不断扩大,由1984年7.62万亩增加到1988年的11.85万亩。由于常规耕翻移栽用工多,成本高,1984年秋我们开始试验采用浅旋朝阳沟移栽油菜,取得了成功。1986—1988年(收获年)三年分别示范推广2.0、6.5和6.85万亩,平均单产185.5、141.0和137.6公斤,比耕翻移栽的增产20.1、13.4和20.8公斤,增产12.2、10.5和17.8％;1988年秋采用这一移栽方式的面积达8.0万亩,占全县油菜面积的70％。 从三年试验推广的实践来看,浅旋朝阳
Rape is the main oil crop in Tai County. In recent years, with the adjustment of planting structure, the area of rapeseed has been constantly expanding, from 76,200 mu in 1984 to 118,500 mu in 1988. As the conventional tillage transplanting more labor and high cost, the autumn of 1984 we began to test the use of shallow Chaoyang ditch transplanting rape, and achieved success. In 1986-1988 (year of harvest), demonstration and popularization of 2.0, 6.5 and 6.85 mu for demonstration in three years were carried out, with average yields of 185.5, 141.0 and 137.6 kg, 20.1, 13.4 and 20.8 kg more than those of tillage and transplanting, with an increase of 12.2, 10.5 and 17.8 respectively %; Autumn 1988 using this transplanting area of 80,000 mu, accounting for 70% of the area rapeseed area. From the practice of three years of experimental promotion point of view, shallow spin sunrise
