日本福岛县岩木市两位农民,从1997年开始,用米糠加发酵肥料、浮萍等治草,取得了明显的效果,不仅抑制了杂草,还增加了地力。米糠加发酵肥料或化肥,提高 PH 值水稻收割后,在农田里散撒米糠和发酵肥料,能促使有分解有机物功能的中温菌、低温菌,在秋-冬-春期间大量繁殖,如以米糠为饵料大量繁殖的黑霉等丝状菌、放线菌等。为了繁殖有用菌类,在散撒米糠、发酵肥料的同时,散撒碳酸钙及硅酸钙20—40公斤/亩,以提高土壤表面的 PH 值。若没有发酵肥料,也可用硫酸铵、过磷酸钙各7公斤/亩和氯化钾3公斤/亩代替,也 Japan’s two farmers in Iwamura, Fukushima Prefecture, Japan, since 1997, with rice bran plus fermentation fertilizer, duckweed and other grass control, and achieved remarkable results, not only inhibited weeds, but also increased soil fertility. Rice bran plus fertilizers or fertilizers to increase the PH value After rice harvest, scattered in the farmland of rice bran and fermented fertilizer, can promote the decomposition of organic function in the temperature bacteria, low temperature bacteria, large quantities during autumn - winter - spring, such as rice bran To feed large amounts of filamentous bacteria such as black mold, actinomycetes and so on. In order to reproduce useful fungi, scattered in the rice bran, fermented fertilizer at the same time, scattered calcium carbonate and calcium silicate 20-40 kg / mu, in order to improve the surface of the soil PH value. If there is no fermented fertilizer, ammonium sulfate, calcium superphosphate can also be 7 kg / mu and potassium chloride 3 kg / mu instead of
