我省现有低湿地3000多万亩,占耕地总面积20%以上。主要集中在三江平原和河流两岸阶地。这类耕地虽然具有土壤有机质丰富,水分充足等优点,但是因为过湿冷浆,限制了土壤潜在肥力的发挥,不仅不利于作物生育,甚至影响农事季节,只能草种粗耕,而成为省内典型的“低产田”。涝害严重的“弃耕地”高达数百万亩。 The province’s existing low wetlands more than 3,000 mu, accounting for more than 20% of the total arable land. Mainly concentrated in the Sanjiang Plain and river terrace. Although this type of arable land has the advantages of rich soil organic matter and sufficient water, it is not only unfavorable to the crop growth, but also affects the agricultural season because of over-wetting slurry, limiting the potential fertility of the soil. Typical “low yield field.” Waterlogging serious “abandoned farmland” up to millions of acres.
