随着城镇建设规模的扩大和高速公路的修建,需要大量的沙石、土方、而取完土方、沙石的场地大都是常年积水、沟壕交错、杂草从生,因无法复耕而被废弃,造成了巨大的土地资源浪费。据不完全统计,仅我县这样的废弃地就有100多处约4000多亩。有些人利用现有的自然条件养鱼,都因水凉、水位无法控制和捕捞困难而失败了。为了废物利用,发展养殖业,今年我们利用两处废沙坑建鱼池30亩,进行了养鱼试验,用科学合理的方法生产及管理,取得了良好的效果,探索出一条新的养鱼模式。
With the expansion of urban construction and the construction of expressways, a large amount of gravel and earthwork are needed. However, most of the sites for gravel and earthwork are perennial water, ditches and weeds, Was abandoned, resulting in a huge waste of land resources. According to incomplete statistics, there are over 40,000 mu of land in more than 100 counties in this county alone. Some people use existing natural conditions to fish, all because of the cold water, uncontrollable water levels and fishing difficulties. In order to utilize waste and develop aquaculture, this year we used 30 mu of fish ponds for construction of two waste sand ditches to carry out fish culture experiments, and produced and managed them in a scientific and rational way. We achieved good results and explored a new fish culture model .
