THE CULTIVATION METHOD OF APPLES HAVING THE HIGH CONTENT OF CALCIUM AND THE EXCELLENT VALUE OF COMMODITIES

摘要

A method for cultivating apples with high contents of calcium and high commercial value is provided to increase the gross weight of the apples, thereby improving marketability. A method for cultivating apples with high contents of calcium and high commercial value comprises the following steps of: applying ionized calcium in a field with the amount of 2kg/330m^2; foliar-fertilizing 0.05~0.20wt% ionized calcium solution during a flower-bud differentiation period, 15 to 20 days after fruit setting, 40 to 45 days before harvesting and 20 days before harvesting; and foliar-fertilizing 0.1% Ecklonia cava seaweed extract solution when the flower was 80 to 90% bloomed, after fertilization, 2 weeks after fruit setting and before and after a rainy season. The Ecklonia cava seaweed extract is obtained by mixing Ecklonia cava seaweed powder and water 5-15 times amount of the powder, agitating at 120rpm, adding a phosphate buffer solution, adjusting pH to 6.1 ~ 7.0, adding cellulase, amylase, and protease, maintaining for 2 hours and filtering it with a 100mum sieve.
