organic fertilizer provided by the invention contains highly active substances and can achieve effects of freeing out lots of
electric charge under the effect of water and breaking down blocking materials in micropores of
soil aggregate, so that the soil restores the granular structure, and the effects of
smoothing gas and heat,promoting growth and activity of aerobic
useful plants, inhibiting and decomposing toxins in soil, increasing the content of organic matters in the soil and providing a loose and swelling growth environment for the
crop root system; and moreover, according to the bean cake
starter and the
humic acid, direct nutritive materials can be provided for tobacco, growth of tobacco plants is promoted, thecost is low, and the
