| abstract |
The present invention relates to a crop growth agent to which oligosaccharide chitosan is added, and 4 to 5% by weight of oligosaccharide chitosan, 8 to 9% by weight of water-soluble calcium, and 3 to 4% by weight of water-soluble phosphoric acid (phosphric aci). It is added to 100% by weight in total. When the crop growth agent of the present invention is diluted 1000 times by adding water and then foliar sanding of crops by spraying means, calcium and phosphoric acid, which are essential nutrients of plants, are quickly and easily absorbed while activating leaf cells by oligosaccharide chitosan. Crops to promote growth, prevent disease and increase crop yields. |
