NOVELTY - Use method of tobacco stalk waste material for producing insect feed, comprises (a) preparing tobacco stalk feed, (b) adding insect feed additive or a complex composition, (c) breeding insects by using the feed mentioned in the step (a) or (b) preparing the tobacco stalk feed insects, and (d) utilizing the insect.    USE - The insect is useful in livestock breeding industry, tobacco organic fertilizer production, tobacco field soil improvement or tobacco seedling substrate in livestock breeding, insect manure (claimed).    ADVANTAGE - The method uses insect, which has strong ability to breakdown biological waste suitable for producing variety of products; is pollution and emission free; enables sustainable recycling; and provide socio-economic benefits.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for insect feed, prepared by either (a1) adjusting the water of tobacco stalk to 11-60%, processing by a crusher or a kneading threading machine to fluffy fiber, crumb-like material or powder and drying until the water content is 10-25% to obtain tobacco stalk feed; (a2) adjusting the water of tobacco stalk to 11-60%, processing by a crusher or a kneading threading machine to fluffy fiber, crumb-like material or powder, conveying to a mixer or kneader at 30-10 degrees C, drying until the material water content is 50-70% under the condition of stirring, kneading and reacting for 10-60 minutes, drying until the water content is 10-25% to obtain the feed, where starch feed raw material can be added in the stirring and kneading process; (a3) adjusting the water of tobacco stalk to 11-60%, processing by a crusher or a kneading threading machine to fluffy fiber, crumb-like material or powder, fermenting the material at 25-65 degrees C for 30 days in tobacco stalk material fermentation can, adding enzyme composition or normal feed raw material, drying the fermented tobacco stalk material until the water content is 10-25% to obtain feed; (a4) adjusting the water of tobacco stalk to 20-70%, processing by a crusher or a kneading threading machine to fluffy fiber, crumb-like material or powder, fermenting the material at 25-65 degrees C for 30 days in tobacco stalk material fermentation can, adding enzyme composition or normal feed raw material, drying the fermented tobacco stalk material until the water content is 11-60%, processing by a crusher or a kneading threading machine to fluffy fiber, crumb-like material or powder, and drying until the water content is 10-25%; or (a5) adding 4-25 times water into tobacco stalk waste material, extracting at 20-100 degrees C for 0.5-24 hours, drying the material, pressing or centrifuging for solid-liquid separation to obtain tobacco stalk waste leach liquor and solid phase tobacco stalk, fermenting tobacco stalk solid phase at 25-65 degrees C for 30 days with addition of enzyme composition or normal feed, or directly processing in a crusher or a kneading threading machine to fluffy fiber, crumb-like material or powder, and drying until the water content is 10-25% to obtain feed, adding yeast extract into tobacco stalk waste leach liquor, fermenting at 25-40 degrees C for 5days to produce yeast protein, separating and drying the protein, blending with tobacco stem feed.
