PURPOSE: A rice cultivating method is provided to include more calcium and Vitamin D than general rice. CONSTITUTION: Crush mussel shell into the size of 1.5 through 10cm. Manufacture mussel oyseter powder by pulverizing after heating at 1000~1200. Crush oyster shell or shell, or oyster and shell into a size of 1. 5 to 10 cm. Manufacture oyster / shellfi shell powder by pulverizing to 350-400 after heating at 1000~1200. A compound powder is made by mixing mussel oyster powder and oyster / shellfi shell powder at a weight ratio of 5~7: 3~5. Dilute compound powder 190-210g in water 25mal and applicate on leaves of ear of rice planted at 1000 pyong or a paddyfield on leaves before 5-15 days to beat them. Repeat application on leaves for 1~5 times to rice plant planted in a 1000 pyong of paddyfield by diluted compound powder 204-260g to water 25 mal when rice plant was ripening. Applicate on leaves of to rice plant planted in a 1000 pyong of paddyfield by diluted compound powder 290-310g to water 25 mal before harvesting rice plant.본 발명은 고비타민D칼슘벼 재배 방법으로서, (1단계)홍합껍질을 1000~1200도로 가열한 후 가루로 분쇄하여 만든 홍합껍질분말을 만들고, 굴껍질 또는 조개껍질, 또는 굴과 조개껍질을 1000~1200도로 가열한 후 가루로 분쇄하여 만든 굴/조개껍질 분말을 만들고, 상기 홍합껍질분말과 굴/조개껍질 분말을 5~7: 3~5 중량%로 혼합하여 혼합분말을 만들고, (2단계) 물 25말에 상기 혼합분말 190-210g을 희석하여 벼논 1000평에 심은 벼가 이삭패기전 5-15일 전에 1회 엽면살포하고,(3단계) 물 25말에 상기 혼합분말 240-260g을 희석하여 벼논 1000평에 심은 벼가 등숙기에 있을 때 1~5회 엽면살포하고, (4단계) 물 25말에 상기 혼합분말 290-310g을 희석하여 벼논 1000평에 심은 벼를 수확하기 7-15일 전에 엽면살포하는 단계들을 포함한다.
