Embodiment 1
[0034] Modified fillers are made by the following steps:
[0035] Step A, after mixing the rice husk and zinc chloride solution with a mass fraction of 40%, put it into a 113° C. The temperature was raised to 510°C at a rate of min and kept for 60 min, and then nitrogen gas was introduced at a flow rate of 220mL / min to cool the reaction system to room temperature, and finally rinsed with deionized water, dried, and sieved to obtain rice husk charcoal, in which rice husk, chlorine The mass ratio of zinc chloride solution is 1:1;
[0036] Step B, add bentonite to deionized water, stir at room temperature for 2 hours, make it fully swell, and obtain a suspension of montmorillonite; add rice husk charcoal to a NaOH solution with a mass fraction of 5%, and stir for 30 minutes to obtain a suspension of rice husk charcoal ;Heat the bentonite suspension to 75°C, add the rice husk charcoal suspension dropwise to the bentonite suspension with a dropping funnel at a rate of 1 drop / secon...

[0038] Modified fillers are made by the following steps:
[0039] Step A, after mixing the rice husk and zinc chloride solution with a mass fraction of 50%, put it into a 113°C constant temperature drying oven for drying and preliminary carbonization for 40min, then place it in a muffle furnace, and heat it at 10°C / The temperature was raised to 510°C at a rate of min and kept for 60 min, and then nitrogen gas was introduced at a flow rate of 220mL / min to cool the reaction system to room temperature, and finally rinsed with deionized water, dried, and sieved to obtain rice husk charcoal, in which rice husk, chlorine The mass ratio of zinc chloride solution is 1:2;
[0040] Step B, add bentonite to deionized water, stir at room temperature for 2 hours, make it fully swell, and obtain a montmorillonite suspension; add rice husk charcoal to a NaOH solution with a mass fraction of 10%, and stir for 30 minutes to obtain a rice husk charcoal suspension ;Heat the bentonite suspensio...

[0042] The ecological fertilizer matrix granules include the following raw materials in parts by weight: 350 parts of rice bran, 35 parts of corn cob, 22 parts of urea, 14 parts of ammonium sulfate, 14 parts of superphosphate, 9 parts of brown sugar, 3 parts of magnesium sulfate, 3 parts of potassium dihydrogen phosphate, 2.5 parts of modified fillers prepared in Example 1, 2.5 parts of bamboo vinegar, and 0.4 parts of composite fermentation powder, which are Bacillus subtilis powder, Bacillus amyloliquefaciens, lactic acid bacteria powder and Bacillus licheniformis powder by mass The ratio is 1:1:1:1 for mixing and forming.
[0043] Ecological fertilizer matrix granules are made through the following steps:
[0044]Step S1: Superfinely pulverize the rice bran and corn cob respectively, pass through a 100-mesh sieve, and stir evenly to obtain a fermentation base material; add urea, ammonium sulfate, superphosphate, brown sugar, magnesium sulfate, and diphosphate to the ferment...
