【摘要】 冷浸田是因长期浸水、土层糊烂与还原作用强烈而造成的一种低产田。采取“深沟”排水,降低地下水位,以改善土壤环境,同时防治水稻因缺钾而引起的赤枯病,可收到显著改良效果。更多还原

【Abstract】 Cold spring paddy soils are the low yielded soils with puddling soil layer formed under strongly reducing condition induced by persistent submergence. Experiment results showed that lowing the ground-water level by deep ditch drainage and controlhng the rice disease by applying potassium fertilizer are the effective measures for the improvement of the soils.更多还原
