NOVELTY - Large-scale cultivation of Eupolyphaga comprises hatching eggs, 1-11 instar nymphs feeding management, adult insect feeding management and spawning insect feeding management. Preparation of the feeding substrate is as follows: crushing surface layer of vegetable garden soil, adding 20-30 vol.% dry chicken manure compost, disinfecting and sieving to form feeding soil, where the feeding soil is added with saw dust after disinfecting and sieving, then added with 0.5% salt water and mixed uniformly, and the moisture content of the feeding substrate is 40 plus minus 2%.    USE - The bioorganic fertilizer is useful in cotton, wheat and corn fields.    ADVANTAGE - The method utilizes feeding substrate which is natural, has no toxicity, is pollution-free, and provides adequate protein and energy. The fertilizer improves the soil quality.    DETAILED DESCRIPTION - Large-scale cultivation of Eupolyphaga comprises hatching eggs, 1-11 instar nymphs feeding management, adult insect feeding management and spawning insect feeding management. Preparation of the feeding substrate is as follows: crushing surface layer of vegetable garden soil, adding 20-30 vol.% dry chicken manure compost, disinfecting and sieving to form feeding soil, where the feeding soil is added with saw dust after disinfecting and sieving, then added with 0.5% salt water and mixed uniformly, the moisture content of the feeding substrate is 40 plus minus 2%, and the volume ratio of the feeding soil and dry sawdust is 3:7.
