specific Embodiment approach 1
[0030] Embodiment 1: This embodiment is a biochar-based organic fertilizer dedicated to millet, which consists of 60 to 70 parts of sheep manure, 10 to 15 parts of peat soil, 15 to 20 parts of straw, and rotten fertilizer in parts by weight. It consists of 5-10 parts of phytic acid, 15-20 parts of biochar and 0.1-1 part of microbial fermentation agent.
specific Embodiment approach 2
[0031]Specific embodiment two: this embodiment is the preparation method of special biochar-based organic fertilizer for millet in specific embodiment one, and the specific steps are as follows:
[0032] 1. Fermentation: Weigh 60-70 parts of sheep manure, 10-15 parts of peat soil, 15-20 parts of straw, 5-10 parts of humic acid, 15-20 parts of biochar and 0.1 to 1 part of microbial fermentation agent;
[0033] Mix 60 to 70 parts of sheep manure, 10 to 15 parts of peat soil and 15 to 20 parts of straw and stack them into a fermentation tank with a depth of 1.5 meters, and add 0.1 to 1 part of microbial fermentation bacteria agent, and then add water to make the mass fraction of water in the mixed material in the fermentation tank be 60% to 70%, and build a heap for closed fermentation for 2 to 3 days. , use a compost turner to turn the compost for the first time, then spray water so that the mass fraction of water in the mixed material in the fermentation tank is 60% to 70%, st...
