THE CULTIVATION METHOD OF APPLES HAVING THE HIGH CONTENT OF CALCIUM

摘要

PURPOSE: A cultivation method of apples with high contents of calcium is provided to obtain apples with high content of calcium by foliar spray after fruit setting the aqueous solution of ionized calcium in a flower bud differentiation period. CONSTITUTION: A cultivation method of apples with high contents of calcium comprises the steps of: performing foliar spray of 0.05 ~ 0.20 weight% aqueous solution of ionized calcium using waste shell in flower bud differentiation period, after fruit set 15-20 days, before harvest 40 ~45 days, and before harvest 20 days; dissolving methionine in 3 times weight water and stirring them at 25C and 200rpm and dissolving 200 weigh ethylenediaminetetraacetic acid; adding 50 times weight calcium chloride based on EDTA weight and reacting it for 5 hours; and adding 3 ~ 8 weight% betain and 0.01 ~ 0.1 weight% vitamin D to prepare a calcium aqueous solution of methionine chelate.
