Chitosan oligosaccharide agricultural composition for improving coloration of plants and application thereof and method by utilizing same to improve coloration of plants

Abstract

The invention relates to a chitosan oligosaccharide agricultural composition for improving coloration of plants and an application thereof and a method by utilizing the same to improve coloration of plants. The invention particularly provides a chitosan oligosaccharide agricultural composition for improving coloration of plants. The weight percentage of the chitosan oligosaccharide in the agricultural composition is 0.0015 to 0.015 percent and is preferentially 0.0025 percent to 0.01 percent. The chitosan oligosaccharide agricultural composition also comprises other ingredients such as one or multiple varieties of glycine, levulinic acid, glutamic acid, phenylalanine, tyrosine, acetylsalicylic acid, genistein, uniconazole, potassium sulphate, monobasic potassium phosphate, dipotassium phosphate, potassium phosphate, calcium chloride and boric acid. The plants include crops and flowers. An evaluation target of the plant coloration is a harvesting target or an ornamental target of the plant such as seeds, fruits, roots, stems, leaves and flowers.

Description

technical field [0001] The invention belongs to the field of agricultural chemistry, in particular to a chitosan oligosaccharide agricultural composition for improving plant coloring and its use and method. Background technique [0002] Anthocyanin is one of the main pigments that make up the color of plants. It is a secondary metabolite of plants. It is a kind of water-soluble natural pigment widely present in plants. Most of the colorful colors of fruits, vegetables, and flowers are related to it. The more anthocyanins are formed, the more beautiful the color of the plant will be. In addition, anthocyanins are pure natural anti-aging nutritional supplements, and are the most effective antioxidants discovered by humans today. At present, most of the pigments used in the food industry are synthetic pigments, and long-term use will endanger human health. Therefore, natural pigments are It has attracted more and more attention of researchers. The increase of plant anthocyani...

Problems solved by technology

[0003] At present, the methods for improving plant coloring mainly include improving plant light conditions, bagging, picking leaves, and laying reflective film, etc., but these methods are either affected by light or require a lot of work.

In addition, spraying naphthaleneacetic acid, ethephon, abscisic acid, etc. can also promote the coloring of apples, but because these plant growth substances will cause the peak of crop respiration, resulting in reduced storage resistance and shortened shelf life
