油菜是贵州省主要油料作物,也是平坝县十字乡的主要油料作物。十字乡油菜常年播种面积1.2万亩左右,平均单产每亩85kg左右,杂交油菜“黔油29号”高产区域单产可达150kg。当前杂交油菜生育期长,为了缓解前后茬季节矛盾,达到高产水平,通常采用育苗移栽技术。但育苗移栽油菜生产投工、投劳多,加上种子、农药、化肥及劳动力价格的上涨,造成油菜生产效益低下,从而影响农民种植油菜的积极性。然而油菜免耕直播技术是一项省工节本、轻型降耗、高产高效的栽培技术。从2012年开始在十字乡示范的稻田免耕化学除草直播油菜技术获得较好的示范效果。
Rape is the major oilseed crop in Guizhou Province and is also the major oilseed crop in the Cross Township of Pingba County. Cross Township annual perennial sown area of 12000 acres, the average yield of about 85kg per mu, hybrid rapeseed “Qianyou 29 ” yield of high yielding area of up to 150kg. The current hybrid rapeseed growth period, in order to alleviate the contradiction between the season before and after the season to achieve high levels of production, usually using seedling transplanting techniques. However, seedling transplanting rapeseed production and processing, more labor, coupled with the seeds, pesticides, fertilizers and labor prices, resulting in rapeseed production efficiency is low, thus affecting the enthusiasm of farmers planting rapeseed. However, rape no-tillage direct seeding technology is a provincial section of this light, reducing consumption, high yield and efficient cultivation techniques. From 2012 onwards in Cross Township demonstration rice tillage chemical weeding direct seeding rape technology to obtain good demonstration effect.
