Embodiment 1

[0019] Embodiment 1. The influence of oligosaccharide florescence prolonging agent on ground planting rose flowering period

[0020] Get chitosan oligosaccharide powder 100mg, sodium alginate oligosaccharide powder 100mg. Manganese sulfate 15mg, zinc sulfate 10mg, boric acid 5mg, sodium molybdate 0.2mg, astaxanthin content 10mg, citric acid 100mg, add clear water to 1L and mix completely to prepare the florescence prolonging agent of the present invention. The object of application is ground roses, which are sprayed at the beginning of flowering stage, and the amount of each spray is 1mL per flower, and the spraying is 3 times in total, and the interval between each spraying is 7 days. Table 1 is the comparison between this flowering period prolonging agent and clear water and the same concentration and formula without oligosaccharides, 50 plants were sampled in each group, and the statistical data.

Embodiment 2

[0024] Embodiment 2. The influence of oligosaccharide florescence prolonging agent on the florescence of ground-planted Magnolia

[0025] Get chitosan oligosaccharide powder 200mg, sodium alginate oligosaccharide powder 50mg. 15 mg of manganese sulfate, 10 mg of zinc sulfate, 5 mg of boric acid, 0.2 mg of sodium molybdate, 20 mg of astaxanthin, 200 mg of citric acid, and 1 L of clear water are added to make the florescence prolonging agent of the present invention. The object of application is ground-planted Magnolia. The tested magnolias all bloomed in early spring and March, and sprayed at the budding stage. The amount of spraying each time was about 5mL per flower, and sprayed 4 times in total, with a spraying interval of 7 days. Table 2 is the comparison between this flowering period prolonging agent and clear water and the same concentration and formula without oligosaccharides, 20 plants were sampled in each group, and the statistical data.

Embodiment 3

[0029] The influence of embodiment 3 oligosaccharide florescence prolonging agent on ground planting chrysanthemum

[0030] Get chitosan oligosaccharide powder 100mg, sodium alginate oligosaccharide powder 100mg. 15 mg of manganese sulfate, 15 mg of zinc sulfate, 5 mg of boric acid, 0.2 mg of sodium molybdate, 10 mg of astaxanthin, 100 mg of citric acid, and 1 L of clear water are added to make the florescence prolonging agent of the present invention. The object of application is ground-planted chrysanthemums. Spraying at the budding stage, spraying 3 times in total, each interval is 7 days, and the amount of application per mu is 30L each time. Table 3 shows the difference between this flowering period prolonging agent and clear water and the same concentration and formula without oligosaccharides. Between the comparison, 30 strains were sampled in each group, statistical data.

Abstract

The invention relates to an oligosaccharide-containing preparation capable of prolonging a flowering period. Contained oligosaccharides are chitosan oligosaccharide and sodium alginate oligosaccharide. The average molecular weight of the oligosaccharides is 500-3000 Da, and the content is 60-300 mg/L. In addition, the preparation also contains trace elements, astaxanthin and citric acid. The flowering period of flowers can be significantly prolonged by spraying or soaking ground-planted flowers, potted flowers and fresh-cut flowers with the preparation. The effective component oligosaccharidesin the flowering period prolonging agent belong to natural products, so the flowering period prolonging agent has no environmental pollution to treated flowers and has no health hazards to a human body; at the same time, the preparation has the advantages of low cost, small application amount, broad flower spectrum, lasting effect and the like, and is simple in application method and easy to promote and apply.

Description

technical field [0001] The invention relates to a fresh-keeping agent for flowers, in particular to an oligosaccharide-containing flowering period prolonging agent and application thereof. Background technique [0002] The flower industry is one of the most dynamic industries in agriculture in the world today. my country is the world's largest producer of flowers. According to statistics, in 2015, the country's flower planting area reached 1.3055 million hectares, with sales of nearly 130.3 billion yuan. At present, the product forms of the flower industry are mainly fresh-cut flowers, potted flowers and ground flowers. These flowers all have a demand for extending the flowering period. Extending the flowering period can increase the commodity value of ornamental flowers, which is important for adjusting the structure of the flower industry and increasing the income of growers. significance. Therefore how to prolong the florescence of flowers and maintain their inherent qu...
