江苏苏南油菜生产现状及产业技术需求分析

苏南油菜生产受区域工业经济发展、务农收入比重减少、生产成本增加、产出效益较低等因素的影响,油菜种植面积下滑。目前栽培方式向稻茬板田种植、免耕直播等转变。对早熟、优质稳产、多抗油菜新品种,以及高效、轻简、全程机械化作业和病、虫、草害综合控制等技术的需求较为迫切。加快培育综合性状优良、适合轻简、机械化作业的新品种,研究与熟化轻简、机械化高效栽培技术,强化对新品种、新技术试验示范和推广,结合科技服务与现场技术指导,制订油菜产业的相关政策等,有利于推进油菜产业发展。

The Current State for the Rapeseed Production and Analyses on Its Industrial Technological Demands in Southern Jiangsu

In Southern Jiangsu the rapeseed production was mainly affected by the regional industrial economic development, the reduction of the proportion of farm incomes, the increase of the production costs and the lower mode was changed output efficiency. The ra to no-tillage paddy field peseed plant area was decreased. At present the cultivation and no tillage direct seeding mode. In the target of technology needs, the early mature; stable yield and multi-resistant new rapeseed varieties; new technology of efficient, light-simplified and full mechanization; integrated insect pest control technology were urgently needed to appear. According to this, the new rapeseed varieties of excellent comprehensive properties and suitable for light-simplification, mechanization should be speeded up to train. The light simplified and efficient mechanized cultivation techniques should be researched. The new varieties and new technology demonstration, technology services and on-site technical guidance should be strength- ened. The relevant policies of rapeseed industry should be formulated. These will be conducive to promoting industrial development of rape.
