平衡施肥的关键在于用地和养地相结合，由于长期大量施用纯化学肥料，造成土壤肥力下降，土壤有机质含量下降，为烟叶生产的可持续发展带来较大隐患。为此，进行了“珍发”牌含氨基酸有机肥、“珍发”牌氨基酸冲施肥与常规烟草专用复合肥对比试验，以期为烟叶生产用肥提供参考 The key to balanced fertilization lies in the combination of land and raising land. Due to the long-term large-scale application of pure chemical fertilizers, the decline of soil fertility and the decrease of organic matter content in the soil will bring great risks to the sustainable development of tobacco leaf production. To this end, carried out “Zhenfa” brand amino acid-containing organic fertilizer, “Zhenfa” brand amino acid fertilizer and conventional tobacco compound fertilizer comparative test, in order to provide a reference for the production of tobacco leaves
