渗水地膜技术研究

Water-Permeable Plastic Mulching Film

阐述了渗水地膜的研制背景、生产技术要点和产品性能指标。作为一种微通透薄膜有两种应用前途,一是用于农田覆盖,能够改善土壤、水、肥、气、热环境,能够提高小雨资源利用率,农作物增产效果达到20%左右;二是用于果蔬贮藏保鲜,能够有效排除CO2等有害气体和抑制O2分压,适于鲜枣类果蔬的保鲜。

The development reason,production technique and product properties of waterpermeable plastic mulching film are presented.As a kind of microporous film,it has two application scopes:(1)it can be used to cover the fields so as to improve the environment of water,fortilizer,air and heat circulation in the soil,enhance the utilization ratio of small rainfall sources,raise the crop output about 20%;(2)it is used to freshen the preserved fruits and vegetables.The film can efficiently eliminate the harmful gases,such as CO2,to which the fruits and vegetables are highly sensitive.The film is suited to fresh date,green pepper and fresh beans etc.
