一、夺取农业稳产高产必须不断培肥地力提高土壤肥力是实现农业稳产高产的重要条件之一。肥力是土壤的基本特性,是作物赖以生长的物质基础。我区土壤肥力偏低,一般土壤有机质含量只有1—1.5%,全氮含量只有0.1%左右,全磷含量只有0.15%,钾素含量较为丰富,一般约有1.5～2.0%。土壤里所含的这些养分绝大部分呈不溶性状态,不能为植物直接吸收利用。据巴盟1977年土壤普查速测结果,在全盟
First, to seize the stable and high-yielding agriculture must continue to fertilize the land to improve soil fertility is one of the important conditions to achieve stable and high-yield agriculture. Fertility is the basic characteristics of soil, is the material basis for crop growth. Soil fertility in our area is low, the soil organic matter content is only 1-1.5%, the total nitrogen content is only about 0.1%, the total phosphorus content is only 0.15%, the potassium content is more abundant, generally about 1.5 ~ 2.0%. Most of the nutrients contained in the soil are insoluble and can not be directly absorbed into plants. According to the 1977 Pugou soil census rapid test results in the alliance
