[0027] The preparation method of above-mentioned light nutrient organic soil, comprises the following steps:
[0028] S1, pile up and ferment plant stalks or residues for 10-15 days, then sterilize at high temperature to obtain semi-fermented plant stalks or residues, and the fermentation maturity is 40-60%;
[0029] S2, the expanded perlite is crushed to 40 orders, and the bentonite is crushed to 20 orders;
[0030] S3. Mix and stir 70-80% of semi-fermented plant stalks or residues, 10-20% of bentonite, 3-8% of carbonized chaff ash, 1-3% of organic fertilizer and 2-4% of expanded perlite in weight percentage 1 to 3 minutes to obtain light organic nutrient soil.
[0031] When mixing semi-fermented plant stalks or residues, bentonite, carbonized chaff ash, organic fertilizer, and expanded perlite, a drum mixer with a capacity of 5 cubic meters can be preferably used, and the mixing time is 1.5 minutes.
