为缓解水资源紧缺现状,全面提升水资源的利用率和水分生产效率,开展M畦膜下沟灌来提高番茄水分生产效率的初步研究。试验采用保护地栽培方法研究番茄M畦膜下沟灌、膜上沟灌和传统畦灌,确定保护地番茄最佳的灌溉方法及灌水量,结果表明设施果类蔬菜灌溉采用M畦膜下沟灌具有节水、节肥、增产、省工、省时及提高水分生产效率的作用,建议在没有滴灌设施的果类菜田优先选用M畦膜下沟灌进行灌溉。
In order to alleviate the current situation of water shortage, improve the utilization rate of water resources and water production efficiency in an all-round way, and carry out the furrow irrigation under M film to improve the water production efficiency of tomato. The protective cultivation method was used to study the furrow irrigation, the furrow irrigation and the conventional furrow irrigation on the M film of tomato, and the best irrigation method and irrigation amount were determined. The results showed that the watermelon irrigation of M & , Saving fertilizer, increasing production, saving labor, saving time and improving the efficiency of water production. It is suggested that irrigation should be given priority to under M film irrigation in fruit vegetable fields without drip irrigation facilities.
