人们已尝试建造了大型脱盐装置来利用含盐地上水,但造价高,结构复杂,不适用.也进一步搞了一些小而简单的装置,但嫌太贵.而且这些装置必须单独靠近每株植物安装.印度科学家改进设计了一种叫做“Jalshuddhi”的新型装置,用于咸水脱盐,同时给苗期植株供水,用有限的水使苗木成功地移植、生长.利用该技术可在干旱缺水并且水质很差以致苗木移植生长困难的地区造林.
Large-scale desalination plants have been attempted to exploit salty groundwater, but they are costly, complex and unsuitable. Some small but simple plants have been further developed, but they are too expensive. These plants must be kept close to each plant Installation Indian scientists have improved the design of a new device called “Jalshuddhi” for desalination of saltwater water while supplying seedlings with water and successfully transplanting and growing seedlings with limited water. And poor water quality and seedling transplant growth difficult areas of afforestation.
