陕西省平利县地处秦巴山区,属北亚热带湿润季风气候区。油菜常年种植面积在0.53~0.67万hm2,移栽面积为0.33~0.40万hm2;常规的油菜栽培方式费时费力,而且投工较大,生产成本较高。通过油菜免耕栽培可以省工省时,降低劳动强度,每667 m2节省生产成本300~400元,增加产量,增加农民收入。在当前农村大量劳动力外出务工,劳力严重不足的情况下,此项技术具有广阔的推广和应用前景。
Pingli County, Shaanxi Province is located in Qinling Mountains, a humid subtropical monsoon climate zone. Rape perennial acreage 0.53 ~ 0.67 million hm2, transplanting area of 0.33 ~ 0.40 million hm2; conventional rape cultivation method takes time and effort, but also a larger investment, higher production costs. No-tillage cultivation by rape can save time and labor, reduce labor intensity, save production cost per 667 m2 300 ~ 400 yuan, increase output and increase farmers’ income. In the current large number of rural migrant workers, a serious shortage of labor, the technology has broad prospects for the promotion and application.
