specific Embodiment approach 1

[0008] Specific embodiment one: a kind of fermented milk cow dung prepares the method for organic fertilizer in the present embodiment is to carry out according to the following steps:

[0009] 1. Five bacterial strains were prepared from Chaetomium torulosum, Geotrichum candidum, Chaetomium dolichotrichum, Trichoderma koningii and Trichoderma viride respectively. Strains' respective mother starters, then respectively prepare 5 strains' respective production starters, and finally prepare 5 strains' respective freeze-dried bacterial powders;

[0010] 2. Weigh 5 to 7 parts of the freeze-dried fungus powder prepared in step 1, 4 to 6 parts of the freeze-dried bacteria powder of Geotrichum candidum, and 3 to 5 parts of the freeze-dried bacteria powder of the long-thorned hair shell prepared in step 1. 3 to 5 parts of Trichoderma konningen freeze-dried bacteria powder and 2 to 3 parts of Trichoderma viridans freeze-dried bacteria powder, after fully mixing, a composite starter is o...

specific Embodiment approach 2

[0013] Specific embodiment two: the difference between this embodiment and specific embodiment one is: the method for preparing the respective mother starters of 5 strains described in step one is: mix 4 parts of the same PDA culture medium and 1 part of wort liquid culture medium Sterilize at a temperature of 121°C for 20 minutes, then cool to a temperature of 30°C to obtain 5 parts of sterilized culture medium, and 4 strains of Trichoderma rotundum, Trichoderma longi, Trichoderma korningen and Trichoderma viride The strains were inoculated into 4 parts of sterilized PDA medium, and 1 strain of Geotrichum candidum was inoculated into 1 part of sterilized wort liquid medium, and finally 5 parts of the medium were cultured on a shaker at a temperature of 28 °C After 24 hours, 5 strains of mother starter were obtained. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0014] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is that: the method for preparing the respective production starters of 5 strains described in step one is: add liquid glycerin, low Xylan and glucose were sterilized for 20 minutes at a temperature of 121°C and then cooled to a temperature of 30°C to obtain a mixed starter, and finally the mixed starter was inoculated with 5 strains of the mother starter respectively, and the mixed starter was inoculated at a temperature of 28°C Under the condition of shaker culture 48h, obtain the production starter of 5 strains respectively; The massfraction of described skim milk emulsion is 10%, and the mass ratio of liquid glycerin and skim milk emulsion is 1:50, oligomeric The mass ratio of xylose to skimmed milk emulsion was 1:100, the mass ratio of glucose to skimmed milk emulsion was 1:100, and the volume ratio of the mixed starter to the mother starters of the five strains was ...

Abstract

A method for making fermented cow excrement into an organic fertilizer relates to a method for preparing an organic fertilizer. The method aims to solve the technical problem that the conventional microorganism inoculant fermentation is low in temperature rising, cellulose degradation rate and degree of composting, and long in fermentation period during the cow excrement high in fiber content is made into the organic fertilizer. The method comprises the steps of freeze-dried bacteria preparation and fermented cow excrement organic fertilizer preparation. The method for making the fermented cow excrement into the organic fertilizer can boost cow excrement ferment temperature rising speed, prolong high temperature time, improve cellulose degradation and the degree of composting of the organic fertilizer product and shorten ferment period, thereby improving the cow excrement fermentation efficiency and the organic fertilizer quality. The method for marking the fermented cow excrement into the organic fertilizer is applied to preparation of organic fertilizers.

Description

technical field [0001] The invention relates to a method for preparing organic fertilizer. Background technique [0002] With the rapid development of my country's large-scale dairy industry, a large amount of solid waste and organic wastewater produced by dairy farming has become one of the main sources of pollution in some areas, especially in the suburbs of large and medium-sized cities. Statistical results show that the total annual discharge of livestock and poultry manure in my country reaches 1.9 billion tons, of which cow manure is about 250 million tons, and it is relatively concentrated. A large amount of cow manure and sewage not only affect the sustainable development of the dairy industry, but also lead to serious pollution of the rural environment and endanger human health. Cow dung contains 14.5% organic matter, 0.30%-0.45% nitrogen (N), phosphorus (P 2 o 5 ) 0.15% ~ 0.25%, potassium (K 2 O) 0.10% to 0.15%. Compared with other livestock, the organic matter...
