我省西北部大多属低洼盐碱地,水质由于受土壤成分的影响,pH值高、盐碱度大,一般不适宜于农作物的生长,甚至是不毛之地。近些年,我省通过挖塘改碱,不仅到了排涝降碱的作用,而且还能养鱼、蓄水。把低洼盐碱地变废为宝,扩大水产养殖面积,提高了土地利用率。但是,由于我省某些低洼
Most of the northwestern part of our province is a low-lying saline-alkali land. Due to the influence of soil composition, the water quality is high and the salinity is high. Therefore, it is not suitable for the growth of crops and even barren land. In recent years, our province through digging ponds to alkali, not only to the role of drainage dumped alkali, but also fish, water. Turn low-lying saline-alkali land into treasure, expand aquaculture area and increase land utilization rate. However, due to some low-lying in our province
