罗平县旱地油菜常年种植面积约4.67万hm~2,近3.0万hm~2适宜机械化播种。2014年引进油菜精量联合直播机(黄鹤牌2BFQ-6)进行示范,该机旋耕、施肥、播种、覆土一次性完成,播种后具有保湿性好、出苗率高,单粒播种、出苗均匀,不需间苗定苗、节约劳动力成本,提高抗旱能力,播种效率高、进度快等优点,但存在着播种不均匀、生产成本过高等问题。针对问题提出对策措施。
Luoping dry land rapeseed perennial planting area of about 46,700 hm ~ 2, nearly 30,000 hm ~ 2 suitable for mechanized planting. In 2014, we introduced the rapeseed precision co-direct seeding machine (Huanghe 2BFQ-6) for demonstration. The machine was rotary-tillage, fertilizing, sowing and soil covering completed in one time. It has good moisture retention, high germination rate, single seeding, Uniform, without the seedling fixed vaccine, save labor costs, improve drought tolerance, high sowing efficiency, faster progress, but there are uneven sowing, production costs are too high and so on. Proposed countermeasures against the problem.
