塑料薄膜具有透光、保温、不漏水等特性,实践中用以育秧的秧棚和种蔬菜用的大棚,就是利用了塑料薄膜的透光、保温特性。至于它的不漏水的特性,在农业生产实践中至今还未被利用。我院的土肥干部,为了拦蓄雨季的地表迳流水以解决红壤早地冬春用水,他们设计了塑料薄膜井和塑料薄膜沟(管),现已引入了迳流水,由于拦蓄的迳流水要保存到次年三月至五月,用于地麦最后一次浇水和玉米的出苗水,因贮水时间长,他们现已定时观测塑料薄膜井的保水情况。希望各地同时开展塑料薄膜的蓄水、保水试验,总结推广。
Plastic film with light, heat, water leakage and other characteristics, in practice, to seedling seedlings and planting vegetables with greenhouses, is the use of the plastic film of light, heat insulation properties. As for its watertight characteristics, it has not been utilized in agricultural production so far. In order to save the surface water from the rainy season in order to solve the winter and spring water use of the red soil, they designed plastic film wells and plastic film ditches (pipes), and now they have dredged water, From March to May of the next year, the emergence water for the last watering of maldives and maize has been regularly observed for the water retention of plastic film wells due to the long storage time. We hope that all over the plastic water storage, water retention test, sum up promotion.
