有机肥并不是一个新鲜的名词,在化肥还没有应用于农业时,我们的祖先就是靠施用天然有机肥来使作物增产的。在商品化的氮、磷、钾化肥问世后,由于其速效养分含量高,对作物产量的影响显著,从而形成了片面施用化肥的现象。 随着无机化肥单一、大量施用,对土壤和作物的危害日趋严重。长期单施无机化肥会使土壤质量退化,造成土壤板结,耕性变差,保水保肥透气性能下降,土壤有机质含
Organic fertilizer is not a new term. When chemical fertilizers have not yet been applied to agriculture, our ancestors used natural organic fertilizers to increase crop yields. After the commercialization of nitrogen, phosphorous and potassium fertilizers, due to the high content of available nutrients, the impact on crop yield was significant, resulting in the phenomenon of one-sided application of chemical fertilizers. With the single, large-scale application of inorganic fertilizers, the hazards to the soil and crops are increasingly serious. The long-term application of inorganic fertilizer alone will degrade the soil quality, resulting in soil compaction, poor cultivability, reduced permeability of water and fertilizer, and soil organic matter content.
