渗水地膜多“V”型覆盖高产栽培技术模式

Model of Water Permeable Plastic Film High Productivity Cultivation Technology in Multi-V Mulching

我国干旱、半干旱地区占全国土地面积的48%,干旱与积温不足是北方地区农作物单产低而不稳的主要原因。渗水地膜及其多"V"型覆盖技术可以有效利用水、热资源,使农作物获得高产,是一项行之有效的好技术。经过多年试验示范,总结出4套技术模式,实践证明其增产幅度比普通地膜覆盖平均增产25%以上。

Arid and semi-arid land accounts for 48% land area in China.Drought and insufficient accumulative temperature are major causes of low productivity of crops in northern China.Water permeable plastic film multi-V mulching model is an efficient technology to increase crop productivity through effective water and heat use.After years widely demonstration 4 models have been refined.The tests showed that the yields of these models increased 25% than the conventional plastic mulching model.
