1. A plant vitalizer comprising:
at least one amino acid or its salt, wherein the at least one amino acid is glycine;
a chitin oligosaccharide; and
at least one oligosaccharide selected from the group consisting of a cellooligosaccharide and a xylooligosaccharide,
wherein the chitin oligosaccharide and the at least one oligosaccharide are the only oligosaccharides in the plant vitalizer, and
the total content of the chitin oligosaccharide and the at least one oligosaccharide in the plant vitalizer is 5 to 10 mass %,
wherein the chitin oligosaccharide is a chemically or enzymatically modified chitin, and
wherein the chitin oligosaccharide comprises a compound of

OG Complex Work Unit Chemistry
wherein some of acetyl groups (COCH3) of the compound are shed, leaving NH2 groups, and a percentage of deacetylation is no greater than 30% of a total chitin oligosaccharide.
