METHOD FOR REDUCING CALCIUM/MAGNESIUM MASS RATIO IN FARM PRODUCT WITH SEAWATER AND CULTIVATION METHOD FOR FARM PRODUCT

摘要

PROBLEM TO BE SOLVED: To provide a method for reducing calcium/magnesium mass ratio in farm product with seawater and a cultivation method for farm product in which the farm product has reduced calcium/magnesium mass ratio, in which growth risk due to salt in seawater is suppressed and much desired mineral, particularly magnesium, is contained in the farm product.;SOLUTION: There is provided a method in which farm product contacts to seawater in a predetermined period after germination of the farm product. For example, cultivation period from germination to harvest is previously designed according to farm product to be cultivated, predetermined period reversing from the timing of harvest is defined as second cultivation period, period reversing from the second cultivation period to germination is defined as first cultivation period, and the farm product is cultivated with successively using seawater during the second cultivation period so as to reduce calcium/magnesium mass ratio of the farm product or harvested farm product is immersed in seawater so as to reduced the calcium/magnesium mass ratio.;SELECTED DRAWING: Figure 6;COPYRIGHT: (C)2016,JPO&INPIT
