PURPOSE: A crops-growing promoter is provided to help calcium and phosphoric acid be easily absorbed into crops by containing aqueous calcium, aqueous phosphate, and oligosaccharide chitosan with an optimum ratio. CONSTITUTION: A crops-growing promoter comprises 4-5wt% of an oligosaccharide chitosan, 8-9wt% of aqueous calcium, 3-4wt% of aqueous phosphate, and residual water. The oligosaccharide chitosan-added crops-growing promoter is diluted 100 times by water. The diluted crops-growing promoter is supplied to crops by a foliage spray through a spraying unit. The crops-growing agent consists of 400g of oligosaccharide chitosan, 800g of aqueous calcium, 300g of aqueous phosphoric acid, and 8.5liters of pure water. |
