“早稻–草莓”水旱轮作模式关键技术集成与示范

Integration and Demonstration of Key Technologies for the “Early Rice-Strawberry” Paddy-Upland Rotation Model

摘要: 针对浙东草莓产区土地季节性闲置、连作障碍及耕地“非粮化”等问题，2024年在临海市开展“早稻–草莓”水旱轮作模式示范试验，集成早稻催芽直播、大棚水稻机割、秸秆还田、草莓高垄滴灌覆膜栽培等关键技术。示范结果：每667 m²早稻产量452 kg，效益656元；草莓产量1500 kg，效益18,000元；两季合计总效益18,656元。该模式实现了用地与养地结合，有效缓解连作障碍，提升土地资源利用率，实现粮经协同发展，是“千斤粮、万元钱”的典型范例，可为浙东草莓产区绿色高质量发展及粮食生产功能区稳粮增效提供实践参考。

Abstract: To address the issues of seasonal land idleness, continuous cropping obstacles, and the “non-grain” utilization of cultivated land in the strawberry-producing areas of eastern Zhejiang, a demonstration trial of the “early rice-strawberry” upland-paddy rotation model was conducted in Linhai City in 2024. Key techniques were integrated, including direct seeding of pre-germinated early rice, mechanized harvesting of rice in greenhouses, straw returning, and high-ridge drip irrigation with plastic film mulching for strawberry cultivation. The demonstration results showed that per 667 m², early rice yield reached 452 kg with a benefit of 656 yuan; strawberry yield reached 1500 kg with a benefit of 18,000 yuan; and the total benefit for the two cropping seasons was 18,656 yuan. This model achieves the integration of land use and soil conservation, effectively alleviates continuous cropping obstacles, improves land resource utilization efficiency, and realizes the coordinated development of grain and cash crops. It serves as a typical example of “a thousand jin of grain and ten thousand yuan in value” and provides a practical reference for the green, high-quality development of strawberry-producing areas in eastern Zhejiang, as well as for stabilizing grain production and improving efficiency in grain functional zones.
