宜昌市油菜产业发展现状及对策——基于农户定点调查数据

Current Situation and Countermeasures of Rapeseed Production in Yichang City——Base on the Fixed-point Investigation of Rapeseed Production

通过农户生产定点调查,分析了湖北省宜昌市油菜产业发展现状和存在的问题。油菜在宜昌市农业生产中的地位突出,存在的主要问题是生产成本高,效益较低;油菜抗灾能力差,产量不稳定。提出改变现有稀植、高肥的大个体栽培方式,通过增加群体密度来提高油菜生产抗灾能力,引导油菜生产向优质化、轻简高效化和标准化方向发展。

The status of rapeseed production of Yichang city was analyzed by fixed-point investigation of 90 rural families. Rapeseed has been playing an important role in rural economy of Yichang. In this area, rapeseed cultivation increased fast, but there were still some critical problems, for example, it was weak resistance to natural disaster and the yield was unstable yearly. Meanwhile, the revenue was low, compared with the production cost in current cultivation model of seedlingtransplant rapeseed with sparse density and plentiful fertilizer. According to the investigation, it was considered that directseeding rapeseed with higher density should be adopted in order to enhance rapeseed＇s resistance to natural disaster and improve its production efficiency.
