传统的油—稻—稻三熟栽培模式,季节矛盾比较突出,除草剂等化学农药一年多次施用,不但增加生产成本,而且影响农产品质量,还污染环境。采用冬季油菜—双季稻免耕减氮节水栽培技术,既开发了冬季油菜生产,又解决了油菜收获后早稻免施除草剂抛秧的问题。同时节约了灌溉用水,节省了翻耕整地费用和时间,缓解了季节矛盾,改善了土壤团粒结构。增产稻谷76kg/667m2,增加油菜籽产量105.4 kg/667m2,增收节支808.6元/667m2。
The traditional oil-rice-rice three-cultivation model, the season more prominent contradictions, herbicides and other chemical pesticides applied many times a year, not only increase production costs, but also affect the quality of agricultural products, but also pollute the environment. Winter rape-double cropping rice without nitrogen reduction and water-saving cultivation techniques, both the development of winter rape production, but also solve the rapeseed harvesting herbicide-free early rice throwing issue. At the same time, water for irrigation is saved, the cost and time for tilling and land preparation are saved, the season contradictions are alleviated and the soil aggregate structure is improved. The yield of paddy is increased by 76kg / 667m2 and the output of rapeseed is increased by 105.4kg / 667m2. The income and expenditure are reduced by 808.6 yuan / 667m2.
