The invention relates to a
sericin multi-effect liquid bioorganic
fertilizer, which comprises 50-80g / L of total nutrients, 250-300g / L of
organic matter content, 20-40g / L of
nicotine content, no more than 50 g / L of water-insoluble matter content, wherein pH value is (
dilution according to ratio of 1:250) is 6.5-7.5. The preparation method comprises the following steps: mixing
sericin fermented liquor with
nicotine leaching liquor according to the ratio of 1:(0.5-1). The liquid
organic fertilizer can increase soil organic matters, inhibit soil hardening, promote the developing of
crop root systems and thick and
solid stalks, is lodging-resistant, and the output is increased. The fruit is improved in quality and good in mouth feeling. The
sericin multi-effect liquid bioorganic
fertilizer is non-toxic and harmless by adopting natural
biological materials, and also has the functions of expelling parasite and killing insects, being sterilized, and inhibiting underground diseases and
insect pests. The sericin multi-effect liquid bioorganic
fertilizer is convenient to apply. In addition, the cleaning production of silk industry can be realized,
pollution discharge is not generated, benefits of enterprises can be increased by changing waste into valuables, the production technology method is simple and convenient, and cost is low.
