近些年，随着水稻生产的发展和“四荒”拍卖力度的加大，许多地方开发和利用荒滩种稻的积极性很高。主要是因为河滩地土壤肥沃，水源充足。但也有不利的一面，即：易涝且渗漏量大，特别是渗漏问题，而新开发的荒滩大都依靠抽水灌溉，因此，如何保水、节水成为增产增收的关键。

In recent years, with the development of rice production and the “four shortage” auctions, the enthusiasm for the development and utilization of wasteland paddy in many places has been very high. Mainly because of the fertile land and enough water. However, there are also disadvantages. For example, it is prone to waterlogging and large amount of leakage, especially the problem of seepage. Most newly-developed wasteland depends on pumping irrigation. Therefore, how to conserve water and save water has become the key to increase yield and income.
