两膜覆盖马铃薯复种辣椒高效种植模式

摘要：为提高土地复种指数，增加农民经济收入，经实践总结，形成了两膜覆盖马铃薯复种辣椒高效种植模式，包括栽培茬口、品种选择、整地播种、肥水管理、两膜覆盖、绿色防控、收获及收后处理等马铃薯栽培技术和复种辣椒育苗定植、田间管理、病虫防治与采收技术，该模式平均每667 m2纯收益16 340元，比传统的两膜马铃薯复种大白菜模式增加效益7 940元，而且通过轮作降低了土壤连作障碍，适宜进一步推广。

Effi cient Planting Mode of Two Film Mulchings for Potatoes Multiple Cropping Peppers

Abstract: In order to improve the land multiple cropping index and increase farmers'' economic income, an effi cient planting mode of double fi lm mulching for potato and multiple cropping of peppers had been formed through practical summary, including cultivation stubble, cultivar selection, land preparation and sowing, fertilizer and water management, double film mulching, green prevention and control, harvesting and post harvest treatment of potato and seedling planting, fi eld management, disease and pest control and harvesting of peppers. This mode had an average net profi t of 16 304 yuan per 667 m2, which was 7 940 yuan per 667 m2more than the traditional mode of two fi lms mulching for potatoes and Chinese cabbage mode. Moreover, it reduced soil continuous cropping barriers through rotation and was suitable for further promotion.
