长期以来,农业上只注重有机肥料中的有机质及氮、磷、钾等营养元素。而利用有机物降解转化过程中产生的生化物质使农作物增产优质的报道尚属鲜见。70年代以来,各省市展开的人工沼气消化(即厌氧消化)的过程中,能产生大量的中间产物,如氨基酸、氨基糖、维生素、激素等,对动、植物营养上具有特异性,促进生长,增强抗逆性等。自80年代以来,国内外在这个领域里已有一些成功的报道。

For a long time, agriculture only focuses on the organic matter in organic fertilizers and nitrogen, phosphorus, potassium and other nutrients. However, the use of organic matter to degrade the biochemical substances produced in the process of conversion of crop yield and quality reports is still rare. Since the 1970s, a large number of intermediate products such as amino acids, amino sugars, vitamins, hormones and the like have been produced during the digestion (ie, anaerobic digestion) of man-made biogas in various provinces and cities, which are specific to animal and plant nutrition and promote Growth, enhance resistance and so on. Since the 1980s, there have been some successful reports in this area at home and abroad.
