Example 2
The invention relates to a method for forming a surface hydrophobic biomass seedling raising pot, which comprises the following steps:
a. mixing: uniformly mixing 80-85 parts of cow dung or sheep dung and 15-20 parts of biomass containing cellulose; the biomass containing cellulose is corn straw;
b. molding: c, continuously heating the material prepared in the step a to 200-250 ℃ under the pressure of 15-25 Mpa, keeping the temperature and the pressure constant for more than 15s, and preparing a molded seedling raising pot;
c. spraying: c, spraying kapok fiber solution on the inner surface and the outer surface of the formed seedling raising pot body obtained in the step b; the kapok fiber solution is prepared by grinding kapok fibers into particles with the particle size less than or equal to 10 microns, adding the particles into triethanolamine aqueous solution and fully mixing the particles; specifically, 18g of kapok fiber is added into 100ml of triethanolamine aqueous solution, and the volume ratio of the triethanolamine to the water is 1.2;
