NOVELTY - Integrated fertilizer feed comprises silage fertilizer. Silage fertilizer is prepared by crushing 50-60 wt.% straw (moisture content 30%) to 2-3 cm, adding 20-30 wt.% livestock manure, 10-12 wt.% rice residue, 10-15 wt.% mushroom residue, 9-10 wt.% rice husk ash and 1-2 wt.% straw decomposition agent, mixing and fermenting for 4-6 days as silage fertilizer.    USE - Method for preparing integrated fertilizer feed with silage fertilizer, high activity biological function fertilizer and plant growth regulator used for promoting crop growth, and silage fermented feed and polysaccharide probiotic used for promoting growth and strengthening immunity of livestock (claimed).    ADVANTAGE - The integrated fertilizer feed increases yield of crops, reduces feeding cost of livestock and eliminates drug residues.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) Preparation of high activity biological function fertilizer comprising mixing 5-8 wt.% silicon-calcium-magnesium powder, 0.1-0.2 wt.% universal strain powder and 54-65 wt.% refined organic fertilizer, performing anaerobic fermentation for 12 hours, adding 40-50 wt.% biotechnology humic acid and packaging; (2) Preparation of plant growth regulator comprising mixing 0.5-1 wt.% lactic acid and 25-30 wt.% water, adding 1.0-1.5 wt.% citric acid, stirring, adding 0.5-1 wt.% chitosan, stirring to obtain chitosan solution, mixing 50-55 wt.% biogas slurry, 20-25 wt.% sugar cane juice, 6-10 wt.% Candida utilis and 0.5-1 wt.% complex amino acid powder, fermenting for 1 hour, adding chitosan solution, mixing and fermenting for 8 hours; (3) Preparation of silage fermented feed comprising crushing 40-50 wt.% corn straw, 20-30 wt.% forage grass, 15-25 wt.% bean straw and 10-15 wt.% rice straw, adding 10-15 wt.% lees, 5-10 wt.% wheat bran, 1-2 wt.% Saccharomyces cerevisiae and 0.5-1 wt.% Aspergillus oryzae, mixing and performing seal fermentation for 6-7 days; and (4) Preparation of polysaccharide probiotic comprising polysaccharide probiotic comprising mixing 95% 100 pts. wt. water and 1-1.5 pts. wt. chitosan, adding 0.5-1 pt. wt. lactic acid and 1-1.5 pts. wt. citric acid, stirring to obtain chitosan solution, heating remaining water at 85 degrees C, adding 1-2 pts. wt. brown sugar, cooling to 30 degrees C, adding 1-2 pts. wt. Lactobacillus acidophilus, activating for half hour, adding chitosan solution and fermenting for 48 hours.
