辽宁省滨海盐渍土的耕地大部分是中度和轻度盐渍化草甸土。耕层全盐量一般在0.2—0.4％之间,季节性变化较大。春季由于耕层返盐,严重地影响了作物的出苗和保苗。另外耕层薄,熟化程度低,其物理性质很坏;一般地块保苗率仅为70—75％,盐斑多的地块保苗率只有50％左右。由于上述诸原因故其产量很低,高粱平均亩产100斤,稗子40—50斤。 Most of the cultivated land of coastal saline soil in Liaoning Province is moderately and slightly salinized meadow soil. Total salt content of tillage is between 0.2-0.4%, seasonal changes. Spring back to salt as a result of plowing, seriously affecting the crop emergence and seedlings. In addition the thin layer of farming, low degree of maturity, its physical properties are very bad; general block seedling rate is only 70-75%, salinization more plots of seedlings only about 50%. Due to the above reasons, the yield is very low, with an average yield of 100 kg of sorghum and 40-50 kg of barnyard grass.
