[0020] Example 1 Preparation of special biological organic fertilizer for leafy vegetables
[0021] In a reactor containing 600 kg of fermented tea residues with an organic mass fraction of 65%, add 130 kg of NPK fertilizer (nitrogen fertilizer: 10 kg ammonium sulfate, 10 kg ammonium nitrate, 10 kg ammonium phosphate, 10 kg urea, phosphate fertilizer: 10 kg phosphoric acid Ammonium, 10kg calcium magnesium phosphate fertilizer, 20kg superphosphate, 10kg diammonium phosphate, 10kg ammonium polyphosphate, potash fertilizer: 10kg potassium sulfate, 10kg potassium chloride, 10kg potassium nitrate), stir and mix, and sterilize to obtain biosolid fermentation material , And then add 80kg auxiliary agent (40kg polycarbonase, 40kg double enzyme) and 8kg microbial inoculum (Bacillus licheniformis, Paecilomyces licheniformis, and Bacillus amyloliquefaciens. Penicillium: Bacillus amyloliquefaciens=37:100:63, the effective number of live bacteria of the microbial agent is 500 million / g), and ...

[0022] Example 2 Comparative preparation of biological organic fertilizer
[0023] A series of bio-organic fertilizers were prepared according to the method of Example 1, in which the related substances and the amounts of the substances were adjusted according to the formula requirements in Table 1 below, where "Ground: Violet: Solution" means Bacillus licheniformis, Paecilomyces lilacinus, The ratio of effective viable bacteria of Bacillus amyloliquefaciens.

[0032] Example 3 Effect of bio-organic fertilizer
[0033] The effective viable count and the shelf life of the bio-organic fertilizer prepared in the above-mentioned Example 1 and Example 2 (Comparative Examples 1-6) were compared, the microbial fertilizer was mixed with the soil, and the viable count before and after mixing for 1 month was detected. Refer to NYT2321-2013 for the detection method of viable cell count; apply the microbial organic fertilizer prepared in the above Example 1 and Example 2 to the spinach crop (5 acres). Before sowing the spinach crop field, apply bio-organic fertilizer to the seedbed soil 0.5 kg / m2, mix evenly and then sow, and fertilize the ground before planting. On average, apply 65 kg of microbial organic fertilizer per mu. Observe the chlorophyll content, yield increase, and disease rate of the examples and comparative examples. The chlorophyll content uses UV-Vis spectrophotometry According to the measurement, the infection rate is measured acc...
