Organic fertilizer converted by waste silkworm faeces and production method of organic fertilizer

Abstract

The invention relates to an organic fertilizer converted by waste silkworm faeces and a production method of the organic fertilizer. The production method comprises the steps of spreading the silkworm faeces to a spreading height of 10-15cm, mixing grenadine syrup with a weight percentage of 10%, lactic acid bacteria and yeast in the proportion of (250-350): (40-60):1, obtaining fermentation liquid after uniform stirring, uniformly spraying the fermentation liquid on the spread silkworm faeces till the silkworm faeces are wet through exactly, spreading a layer of silkworm faeces to a spreading height of 10-15cm again on the sprayed silkworm faeces, uniformly spraying the fermentation liquid till the silkworm faeces are wet through exactly, treading down, covering a film on the silkworm faeces, keeping for 15-30 days, turning, covering with a film for 10-15 days again, adding phosphorus and potassium to the silkworm faeces, with a weight ratio of silkworm faeces, phosphorus and potassium of 100:(3-6):(1-4), pelleting, drying, bagging, and then obtaining a finished product. The waste silkworm faeces are converted into the environment-friendly organic fertilizer, so that the problem that the silkworm faeces pollute the environment can be solved, endogenesis hormone secretion of plants can be stimulated, the tillering capacity of plant cells is high, the effective stems are more, the crop planting requires no nitrogenous fertilizer for prompting growth, and the quality is good.

Description

technical field [0001] The invention relates to the technical field of organic fertilizers, in particular to a production method for converting waste silkworm dung into environmentally friendly organic fertilizers. technical background [0002] my country is the largest sericulture country in the world and has the longest history of sericulture. According to statistics, my country's silkworm production covers more than 1,000 counties in 26 provinces across the country, and the area of ​​mulberry and oak gardens exceeds 1.5 million hm 2 , There are more than 20 million sericulture households. In recent years, my country's silk industry, which uses silkworm cocoons as raw materials, has an annual industrial output value of more than 150 billion yuan, and the annual foreign exchange earnings of cocoon and silk products are more than 3 billion US dollars. The output and export volume of cocoon and silk both account for 70% of the world's total. It is a big cocoon silk country t...

Problems solved by technology

[0004] At present, the treatment of silkworm manure is usually directly used as farmland fertilizer or discarded. However, since fresh silkworm manure contains certain pathogenic bacteria, directly using it as fertilizer or discarding it will pollute the silkworm production environment, and even lead to the outbreak of silkworm disease. Silkworm manure has become one of the main non-point source pollutants in the silkworm area, and the solution to silkworm manure pollution has also become a major problem in silkworm production
