塑料薄膜袋子能装水,这是人们都知道的。可是,要把能装水放金鱼的小塑料袋子发展成能装十多吨水、保蓄半年以上的塑料薄膜井还没有人实践过。这里仅就我几个月来对塑料薄膜井蓄水的实践作个粗浅的介绍。一、塑料薄膜井的设想。在红壤旱地的研究中,我们深感冬春旱季缺水是红壤旱地小春作物增产的一大障碍。可是,夏秋两季里却有大量迳流水从广阔的旱地流走,并造成土壤冲刷。想办法把雨季里部分迳流水就地拦蓄起来作为旱季生产用水,这是人们多年来希望解决而尚未解决的问题。要拦蓄迳流
Plastic film bags can be filled with water, which is known to all. However, it is not yet practiced to develop small plastic bags capable of holding water and containing goldfish into plastic film wells capable of holding more than 10 tons of water and preserving more than six months. Here is just a brief introduction to the practice of plastic film wells in a few months. First, the idea of plastic film wells. In the study of drylands of red soils, we are deeply impressed by the lack of water during the winter and spring dry seasons, which is a major obstacle to the yield increase of small spring crops in red soil drylands. However, in summer and autumn, a great deal of water flows away from the vast drylands and causes soil erosion. It is an unsolved problem people have been trying to solve for many years to find ways to save some of the water in the rainy season and save it for production in the dry season. To save the ilk
