the nitro compound is phosphorus nitrate;
b, mixing the agricultural production organic waste, the fermentation bacteria yeast and the activated amino acid in a fermentation factory building with a sunshade and a rainproof function, and naturally fermenting; 1.5-3.0 kg of the activated amino acid is added to each ton of the organic waste after fermentation;
and C: naturally fermenting for 22-30 days to obtain the activated amino acid organic fertilizer;
s2, soil improvement:
the prepared activated amino acid organic fertilizer is used for soil improvement, the application amount of the activated amino acid organic fertilizer is 110-160 kg/mu, and the activated amino acid organic fertilizer is applied once a year.
2. The method for improving soil improvement effect of organic fertilizer with activated amino acid as claimed in claim 1, wherein in step B, agricultural production organic waste, fermentation starter and the activated amino acid are mixed and piled into strips with a bottom width of 3-4 m, a top width of 1.5-2.0 m and a height of 1.8-2.0 m; turning over every 7-9 days.
