NOVELTY - Preparing spherical nutrient product and nutrient matrix, by crushing corn straw, mixing crushed corn straw, humus and cow dung, stacking mixture, subjecting mixture to fermentation, drying fermented material, crushing dried material to obtain mixed material (A), mixing mixed material (A), vermiculite and perlite to obtain mixed material (B), mixing mixed material (B), water retention agent and binder to obtain mixed material (C), mixing mixed material (C) and water, pressing mixture by mold and drying obtained pressed spherical nutrient product.    USE - The method is useful for preparing spherical nutrient product and nutrient matrix used for pepper (claimed). The nutrient product and nutrient matrix are useful for improving growth of pepper seedlings.    ADVANTAGE - The method enables preparation of the spherical nutrient product and nutrient matrix that improves seed germination, seedling and seedling survival rates of the pepper, as the nutrient product or matrix effectively prevents change in temperature and humidity of soil surface with respect to any environmental changes. The method expands or promotes application prospects of pepper.    DETAILED DESCRIPTION - Method for preparing spherical nutrient product and nutrient matrix, involves (a) crushing corn straw to obtain 2 cm or less crushed product, adding and mixing 65-75 pts. vol. crushed corn straw, 15-25 pts. vol. humus and 15-25 pts. vol. cow dung, stacking obtained mixture, subjecting the mixture to fermentation, drying obtained fermented material, crushing obtained dried material by crusher to obtain mixed material (A) having particle size of 0.3-0.8 mm, adding and mixing 65-75 pts. wt. mixed material (A), 12-18 pts. wt. vermiculite and 12-18 pts. wt. perlite to obtain mixed material (B), mixing 90-110 pts. wt. mixed material (B), 4-6 pts. wt. water retention agent and 4-6 pts. wt. binder to obtain mixed material (C), mixing 90-110 pts. wt. mixed material (C) and 8-10 pts. wt. water, pressing obtained mixture by mold and drying obtained pressed spherical nutrient product, and (b) crushing corn straw to obtain 2 cm or less crushed corn straw, adding and mixing 65-75 pts. vol. crushed corn straw, 15-25 pts. vol. humus and 15-25 pts. vol. cow dung, stacking obtained mixture, subjecting the mixture to fermentation, drying obtained fermented material, crushing obtained dried material by crusher to obtain mixed material (A) having particle size of 0.3-0.8 mm, adding and mixing 75-85 pts. wt. mixed material (A), 8-12 pts. wt. vermiculite and 8-12 pts. wt. perlite to obtain mixed material (B), mixing 90-110 pts. wt. mixed material (B), 4-6 pts. wt. water retention agent, 1-2 pts. wt. carbendazim and 0.05-0.15 pts. wt. copper sulfate to obtain mixed material (C), and mixing the mixed material (C) with equal quantity of park soil to obtain nutrient matrix.
