很早以前,我国北方地区的农户喷施米醋获得了小麦、蔬菜增产和品质改善,这是在农业生产中最早应用有机水溶性叶面肥的实例。日本在19世纪战争中发现,生产干馏松节油产品的废液流入稻田使水稻发病减少,而在相对较远的稻田,虽有轻微发病,但是水稻的产量却明显提高,更令当地农民惊讶的是在炭窑附近的蔬菜生长更好,品质更优。他们对这种现象进入了深入的研究,发现木酢液、竹酢液(即木竹干馏炭化过程中产生的废液)可以促进农作物根系生长和地上部分枝叶的生长发育,还能杀菌防除病虫害。因此,日本在20世纪80年代开始将木酢液、
Long ago, farmers in northern China sprayed rice vinegar to obtain wheat and vegetables to increase production and improve quality, which is the earliest example of application of organic water-soluble foliar fertilizer in agricultural production. In the 19th century Japan, Japan found that the flow of waste water from the production of distilled turpentine products into paddy fields reduced the incidence of paddy rice. However, in some relatively remote paddy fields, the yield of paddy rice increased but the output of paddy rice was significantly increased. Vegetables near the charcoal grow better and have better quality. They came to an in-depth study of this phenomenon and found that wood vinegar liquid, bamboo vinegar liquid (that is, waste water produced during the retorting and charring of wood bamboo) can promote the growth of crop roots and branches and leaves, and can also kill bacteria and pests. Therefore, Japan in the 20th century, 80 began to wood vinegar liquid,
