Embodiment 1

[0021] The cultivation of embodiment 1 bacterial classification

[0022] 1) Preparation of nutrient broth agar seed medium: 100g of peptone, 30g of beef extract, 50g of NaCl, 10L of distilled water, pH7.0, sterilized at 121°C for 15min, cooled for later use.

[0023] Preparation of seed solution: Inoculate Bacillus subtilis into the seed medium and culture at 37° C. for 8-12 hours to obtain seed solution; Bacillus subtilis was purchased from Institute of Microbiology, Chinese Academy of Sciences, number 1.1086.

[0024] 2) Preparation of seed medium: weigh 500g of glutamic acid, 500g of glucose, and 9000g of water; first add a small amount of water to glutamic acid and glucose to dissolve them, and then add the remaining water; sterilize at 115°C for 20 minutes, Let cool and set aside.

[0025] Preparation of seed solution: Inoculate Bacillus Nongguan No. 1 into the seed medium, and culture at 40-60° C. for 8-12 hours to obtain seed solution. Nongguan No. 1 Bacillus is a str...

Embodiment 2

[0028] Select any seed solution cultivated above, and spray it evenly into the material according to 1-3% of the weight of the material to be fermented, with a carbon-to-nitrogen ratio (C / N) of 20-30, and adjust the initial water content between 40-60% , mixed evenly, cultivated at 60-70°C for 15-30 days, turned over every 7 days, and the finished product was obtained after fermentation.

[0029] The material to be fermented is one or more of human and animal manure, household waste or plant straw; compost fermentation can be used or related fermentation equipment can be used for fermentation. If compost fermentation is used, the heat generated by the growth of microorganisms is used to maintain the temperature. The temperature difference between winter and summer is large, the fermentation time required in summer is short, and the fermentation time is longer in winter; and the components or component ratios of the materials to be fermented are different, and the required ferme...

Abstract

The invention relates to a gama-PGA-containing microbial organic fertilizer with moisture and fertility retention functions and a preparation method of the microbial organic fertilizer. The preparation method comprises the steps of retaining moisture for organic fertilizer, evenly spraying seed fluid in the organic matters by 0.1 to 1 percent weight of materials to be fermented, regulating the initial moisture ranging from 40 to 60 percent, evenly mixing carbon-nitrogen (C / N) ratio of 20-30, culturing for 15 to 30 days at 60-70 DEG C, turning over and mixing for each seven days, and fermenting, thus obtaining finished products. The microbial organic fertilizer has superstrong hydrophilcity and heavy metal moisture-retention adsorption capability, as well as endurable slow release function, and can improve physicochemical property of soil, and promote root growth.

Description

technical field [0001] The invention relates to the field of organic fertilizers, in particular to a bio-organic fertilizer containing microbial metabolite gamma-polyglutamic acid and having the function of water and fertilizer retention and a preparation method thereof. Background technique [0002] Proper irrigation is required to ensure a good harvest of crops. However, my country's water resources are seriously insufficient, and the distribution is uneven, with more in the south and less in the north, more in summer and less in winter. At present, the method of flood irrigation is mostly used, and the waste is serious. After irrigation, most of the water and fertilizer evaporate or lose, which cannot play the expected role. Therefore, the problem of water and fertilizer conservation after irrigation has become a difficult problem to be solved urgently in agriculture. [0003] γ-poly glutamic acid (γ-poly glutamic acid, γ-PGA) is a water-soluble polyamino acid produced ...
