土壤普查结果,我县土壤有机质平均含量为1.04％,各种养分也是低水平的。近年来,随着粮食产量的增长,土壤肥力逐步下降,这就出现了种地和养地的矛盾。主要原因是有机肥的投入大量减少。其表现为: 一、有机肥与无机肥的比例失调近年来,化肥在农业增产中起了很大作用。有些群众就认为粗肥不如化肥见效快,把施用化肥作为提高产量的主要手段,甚至过量施用,对有机肥的施用却明显减少。这是当前农业生产中存在的严重问题。连年大量施用化肥,不仅使土壤养分不稳
Soil census results, the average soil organic matter in our county was 1.04%, a variety of nutrients is also low level. In recent years, with the increase of grain output, the soil fertility has gradually decreased, which led to the contradiction between planting and raising land. The main reason is a substantial reduction in the input of organic fertilizer. Its performance as follows: First, the proportion of organic fertilizer and inorganic fertilizer imbalance In recent years, fertilizer in agricultural production has played a significant role. Some people think that crude fertilizer is not as effective as fertilizer, and the use of chemical fertilizers as the main means to increase production, or even over-applied, significantly reduced the application of organic fertilizer. This is a serious problem in current agricultural production. Years of heavy application of fertilizers, not only to soil nutrient instability
