specific Embodiment 1

[0017] Take 60 parts of bamboo shoot shells, 40 parts of chicken manure, 1 part of microbial agent (40 parts of cellulolytic bacteria, 40 parts of saccharomyces, 20 parts of mesophilic bacteria), adjust the water content at 65%, mix evenly, and place in a fermentation tank. After fermenting for 25 days, air-dry naturally until the water content is 10-20%, and crush it for later use. Fully mix 65.3% bamboo shoot shell fermentation material with 17.4% urea, 7.14% monoammonium phosphate, 6.67% potassium chloride, 2% magnesium sulfate, 0.5% borax, and 1% zinc sulfate to make special fertilizer for cotton. The organic matter of this product is > 40 %, NPK>18%. In the flowering and boll stage of cotton, applying 80 kg of special fertilizer for cotton with bamboo shoot shells per mu compared with conventional fertilization can make the cotton stems and branches strong, grow vigorously, increase the number of bolls, increase the weight of bolls, reduce the number of bolls, and increas...

specific Embodiment 2

[0019] Take 70 parts of bamboo shoot shells; 30 parts of sheep manure; 0.5% microbial agent, adjust the water content at 60%, stack and ferment for 15 days, dry it in a dryer until the water content is about 15%, and crush it for later use. Mix 62.0% bamboo shoot shell fermentation material with 17.4% urea, 7.14% monoammonium phosphate, 10% potassium sulfate, 2% magnesium sulfate, 0.5% borax, and 1% zinc sulfate to make a special fertilizer for citrus. The organic matter of this product is 37% , NPK>20%. The fertilizer is used for 50-80 kg / mu of citrus fruit strengthening fertilizer. Compared with conventional fertilization, the number of fruit per plant, the weight of single fruit and the yield are all increased. 15-20%.

[0020] All the components are parts by weight.

Abstract

The invention relates to a preparation process of multifunctional bamboo-shell organic-inorganic composite fertilizer, which comprises 60 to 70 parts of bamboo shell, 30 to 40 parts of manure and 0.5 to 1 part of micro-organism microbial inoculum (consisting of 40 to 50 parts of cellulose-decomposing bacteria, 30 to 40 parts of yeast and 10 to 20 parts of mesophile), and is characterized in that the above raw materials are fermented for 15 to 30 days, bamboo-shell organic fermentation materials are proportioned with conventional N, P and K inorganic fertilizer and middle-micro element fertilizer according to the nutrition required for different crops and different growth periods after being dried and crushed, the bamboo-shell resource can be transformed to the special organic-inorganic composite fertilizer with 20 to 40 percent of organic substance and 15 to 25 percent of nitrogen, phosphorous and potassium through pelleting, so the recycling of bamboo-shell waste is realized, and remarkable economic, social and ecological benefits can be created.

Description

technical field [0001] The invention belongs to comprehensive pollution control and waste recycling in the field of environment, and relates to a process for producing high-quality compost and multifunctional organic-inorganic compound fertilizer by fermenting waste bamboo shoot shell resources through microorganisms. Background technique [0002] Various agricultural wastes are the difference in material and energy between resource input and output in the chain of agricultural production and reproduction, and are the loss share of material and energy generated in the process of resource utilization. They are used for fertilizer development, especially organic and inorganic waste. The development of functional compound fertilizers meets the nutrient requirements of different crops while avoiding the deterioration of soil properties and maintaining the balance of agricultural ecology, which is in line with the development trend of modern agriculture. Abandoned bamboo shoot sh...
