[0018] Biochar granulated organic fertilizer formula: 50% biochar, 30% organic fertilizer, 20% oyster shell powder. Prepare the biochar granulated organic fertilizer from the above raw materials according to the following method: pass the raw materials through a 60-mesh sieve respectively, add them to the mixer, stir at a speed of 60 times / min for 10 minutes, mix well, and add water to the mixed fertilizer powder The mass ratio of water and solid mixed raw materials is 0.7:1. After stirring evenly, it is sent to a kneading granulator, and the granulated fertilizer is sent to a dryer for drying at 60°C, and the dried raw Substance Charcoal Granulated Organic Fertilizer Finished for Plant Growth Tests in Soilless Cultivation.
[0019] (1) Basic physical and chemical properties test
[0020] The results show that the pH value of the prepared biochar granulated organic fertilizer is basically between 6.61-6.75, which is a neutral level; the EC of the particles is 29.4-34.9mS.cm ...
