干热河谷区番茄-甜玉米一膜两用免耕栽培技术

No-Tillage Cultivation of Tomato-Sweet Corn with One Single Mulching of Plastic Film in the Dry-hot Valley Region of Yunnan

为减少地膜使用量,提高地膜使用效率,降低农业生产成本,提高农业生产效益。于云南干热河谷区元谋县开展番茄-甜玉米一膜两用免耕栽培试验示范和效益分析。结果表明,地膜的利用率可提高1倍,纯收益每667 m^(2)增加6.27%。番茄-甜玉米一膜两用免耕栽培技术的实践与推广,能有效解云南干热河谷区农业自然降水利用率低的问题,还能降低农业生产成本,提高农业生产效益,对云南干热河谷区农业发展具有重要的意义。

To reduce the amount of mulching film used,improve the efficiency of mulch use,reduce agricultural production costs and improve agricultural production efficiency,an experimental demonstration and benefit analysis of using one mulch film in no-till cultivation of tomato-sweet corn were conducted in Yuanmou County of Yunnan's dry hot valley region.The results showed that the utilization rate of the mulch film was increased by two folds and that the net income increased by 6.27%peracre.The practice and promotion of no-till cultivation of tomato-sweet corn with one single mulching of plastic film can effectively solve the problem of low utilization of natural precipitation,reduce agricultural production costs and improve agricultural production efficiency in the dry hot valley region of Yunnan,which is of great significance to the agricultural development in the dry hot valley region of Yunnan.
