摘　　要：基于夏闲季节在专业菜场推广应用的"菜-中稻-菜"轮作制是惠阳区近几年重点推广的高效耕作模式,其推广应用面积正逐年扩大。应用水稻测土配方施肥技术在中稻上进行表征试验,探索中稻合理的施肥技术。结果表明,应用水稻测土配方施肥指标体系指导中稻生产,可达到节氮、节磷、降低栽培风险的效果,取得了良好的经济效益和生态效益。提高资源利用效率是农业可持续发展的核心,基于菜地中稻的气候环境、土壤状况、病虫害等因素,在产量定位上以获得稳产的中等产量为宜。In the summer fallow seasons the ＂vegetable- middle season rice- vegetable＂ rotation system in the specialized vegetable plot is a highly efficient cultivation mode promoted by Huiyang district in recent years. The application area was expanding year by year. Rice soil testing technology was applied to the middle season rice for a proper fertilization method. The results showed that the rice soil testing and formula fertilization criteria led to saving of nitrogen and phosphate, reduction of the effect of cultivation risk, and achievement of good economic and ecological benefits. Provided high resource utilization efficiency is the core of sustainable development of agriculture, and the factors such as climate, soil conditions, diseases and insect pests of middle season rice in vegetable plot, obtaining stable and moderate yield is advisable.
