carrying out water pressing treatment on the hemp stems obtained by cutting and separating through a high-pressure squeezer to obtain hemp water and short fibers, and drying the short fibers to enable the water content to be below 13%, so that the hemp stems can be sold as short fiber product raw materials;
5) mixing the hemp water obtained in the step 2) and the hemp water obtained in the step 4), adding fermentation microorganism bacteria and methane microorganism bacteria, fermenting for 20-25 days to obtain a bottom hemp water precipitate, a middle hemp water liquid fertilizer and upper methane, outputting the upper methane as a fuel, outputting the middle hemp water liquid fertilizer as a fertilizer, selling, extracting tigogenin from the bottom hemp water precipitate;
6) collecting the hemp residues obtained in the steps 2) and 3) and then using the collected hemp residues for cultivating seed mushrooms, or putting fermentation microorganisms into the hemp residues for fermentation and then using the fermented hemp residues as raw materials for preparing feed and fertilizer.
2. The comprehensive sisal hemp utilization and treatment method of claim 1, wherein in the steps 2) and 4), the water yield of hemp water is controlled to be 70% during pressurized water treatment.
3. The comprehensive sisal hemp utilization and treatment method according to claim 1, wherein in the step 5), the fermentation microorganism bacteria and the methane microorganism bacteria are added twice, the first adding amount of the fermentation microorganism bacteria and the first adding amount of the methane microorganism bacteria are both 2 per mill of the total amount of the reaction system, the second adding amount of the fermentation microorganism bacteria and the second adding amount of the methane microorganism bacteria are both 1 per mill of the total amount of the reaction system, and the interval time between the two adding is 10 days.
4. The comprehensive sisal hemp utilization and treatment method according to claim 1, wherein in the step 6), the amount of the fermentation microorganism bacteria is 2% o of the total amount of the sisal dregs.
