Embodiment 1
[0024] Prepare a new type of multifunctional humic acid-free film bag, which is prepared from the following components by mass: humic acid 10kg, potassium hydroxide 10kg, chitosan 15kg, nano-SiO 2 1.1kg, glycerin 0.6kg, fenugreek gum 1.0kg, water 30kg.
[0025] The above raw materials are all commercially available products, and there is no restriction on the manufacturer.
[0026] Preparation method: First, 0.6kg of nano-SiO 2 , dissolve in 0.2% acetic acid aqueous solution, stir evenly, add 15kg chitosan, add 0.6kg glycerin after fully dissolving, stir evenly, obtain chitosan composite mother liquor.
[0027] Then get 10kg of humic acid and dissolve it in potassium hydroxide solution to make potassium humate solution, and dissolve 1.0kg of fenugreek gum in it; Potassium humate solution of glue, and then add the remaining glycerin under the action of stirring until a stable and uniform system is formed, that is, the mother liquor of humic acid free film bag is obtained.
Embodiment 2
