Abstract
本发明涉及一种含寡糖的能够延长花期的制剂。所含寡糖为壳寡糖和海藻酸钠寡糖，寡糖平均分子量为500‑3000Da,含量为60‑300mg/L，此外还含有微量元素、虾青素和柠檬酸。通过使用该制剂对地栽花、盆栽花和鲜切花进行喷施或浸泡处理，可显著延长花卉的花期。本发明花期延长剂中有效成分寡糖属于天然产物，对于处理后的花卉无环境污染，对人体无健康危害，同时具有成本低廉、施用量小、花谱宽广和作用持久等优点，而且施用方法简单、易于推广应用。The invention relates to an oligosaccharide-containing preparation capable of prolonging flowering period. The oligosaccharides contained are chitosan oligosaccharides and sodium alginate oligosaccharides, the average molecular weight of oligosaccharides is 500-3000Da, and the content is 60-300mg/L. In addition, it also contains trace elements, astaxanthin and citric acid. By using the preparation to spray or soak ground flowers, potted flowers and fresh cut flowers, the flowering period of flowers can be significantly prolonged. The active ingredient oligosaccharide in the florescence prolonging agent of the present invention belongs to natural products, has no environmental pollution to the treated flowers, has no health hazards to the human body, and has the advantages of low cost, small application amount, broad flower spectrum and long-lasting effect, and the application method Simple and easy to promote applications.

本发明涉及一种花卉保鲜剂，具体的说是一种含寡糖的花期延长剂及其应用。The invention relates to a fresh-keeping agent for flowers, in particular to an oligosaccharide-containing flowering period prolonging agent and application thereof.
背景技术Background technique
花卉产业是当今世界农业中最具活力的产业之一。我国是世界花卉生产大国，据统计，2015年全国花卉种植面积达130.55万公顷，销售额近1303亿元。目前花卉产业的产品形态主要为鲜切花、盆栽花和地栽花，这些花卉都存在延长花期的需求，延长花期可以提高观赏花卉的商品价值，对调整花卉产业结构、增加种植者收入都有重要意义。因而如何延长花卉花期，保持其固有品质，成为花卉生产者、经销商、消费者及园林工作者所共同关注的问题。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 quality has become a common concern of flower producers, distributors, consumers and gardeners.
目前对于花期延长的技术主要集中于鲜切花的花期延长及保鲜方面。传统的鲜切花保鲜剂多含有AgNO3、8-HQS(8-羟基喹啉)等化学药剂成分，具有一定的毒性，且AgNO3具有光敏感性，极易沉淀和使茎杆切口变黑，影响鲜切花及瓶插液的外观，存在不足。也有报道以稀土为主要成分的花期延长剂，但由于稀土是不可再生的矿物资源，存在价格昂贵的问题，也不是理想的花期延长剂。At present, the technology for prolonging the florescence mainly focuses on prolonging the florescence and fresh-keeping aspects of fresh-cut flowers. Traditional fresh-cut flower preservatives mostly contain chemical ingredients such as AgNO 3 and 8-HQS (8-hydroxyquinoline), which have certain toxicity, and AgNO 3 is light-sensitive, and it is easy to precipitate and blacken the cut of the stem. It affects the appearance of fresh-cut flowers and bottle cutting solution, and there are deficiencies. There are also reports of flowering period prolonging agents with rare earth as the main component, but because rare earths are non-renewable mineral resources, there is a problem of high prices, and they are not ideal flowering period prolonging agents.
对于地栽花和盆栽花花期的延长，报道不是很多，主要手段为物理方法，如认为增加光照时间、创制低温环境等可延长花期，然而这些手段成本较高，仅能适用于小面积地栽花和小量盆栽花。也有报道使用激素可以延长观赏植物花期，如赤霉素可促进菊花提前开花5天，延长花期7天，花量增加。水杨酸可抑制顶端分生组织的生长，矮化植物，通过抑制乙烯的生物合成，延缓植物器官衰老，从而延长花期。但激素使用存在剂量较难控制的问题，剂量使用不当，会产生相反的作用。There are not many reports on the prolongation of the flowering period of ground and potted flowers. The main means are physical methods. For example, increasing the light time and creating a low temperature environment can prolong the flowering period. However, these methods are expensive and can only be applied to small-scale ground plants. Flowers and a small amount of potted flowers. It has also been reported that the use of hormones can prolong the flowering period of ornamental plants. For example, gibberellin can promote chrysanthemums to bloom 5 days in advance, prolong the flowering period by 7 days, and increase the amount of flowers. Salicylic acid can inhibit the growth of apical meristems, dwarf plants, and delay the aging of plant organs by inhibiting ethylene biosynthesis, thereby prolonging the flowering period. However, there is a problem that the dosage of hormones is difficult to control, and improper dosage will produce the opposite effect.
寡糖由聚糖降解得到，来源于天然产物，研究发现一些寡糖类物质具有增强植物应对病虫害的能力、调节植物生长发育的功能。壳寡糖是氨基葡萄糖通过β-l，4-糖苷键连接而成的，是自然界唯一的碱性寡糖。自上世纪70年代以来，壳寡糖就被应用于植物保护领域，并显示出非常好的抑菌生物活性。海藻酸钠寡糖是由а-L-甘露糖醛酸(mannuronicacid,M)与b-D-古罗糖醛酸(guluronic acid,G)通过1，4-糖苷键连接并由不同片段(MM段、GG段和MG段)组成的低聚糖，具有相对分子质量小、吸收性强等优点。海藻酸钠寡糖对植物生长发育具有一定的调节功能，对植物的抗逆和提高品质也有显著效果。寡糖具有诱导植物抗性、促进植物生长等功能。但目前上述寡糖作为花期延长剂的研究和开发应用的还未见文献和专利报道。寡糖来源于天然产物，具有安全、环保、低残留等特点，用于花期延长剂，相对于其它手段而言更具有优势。同时还具有成本低廉、施用量小等优点，具有广阔的应用前景。Oligosaccharides are obtained from the degradation of polysaccharides and are derived from natural products. Studies have found that some oligosaccharides can enhance the ability of plants to cope with pests and diseases and regulate plant growth and development. Oligochitosan is formed by connecting glucosamine through β-1,4-glucosidic bonds, and is the only alkaline oligosaccharide in nature. Since the 1970s, chitosan oligosaccharides have been used in the field of plant protection and have shown very good antibacterial biological activity. Sodium alginate oligosaccharides are composed of а-L-mannuronic acid (mannuronic acid, M) and b-D-guluronic acid (guluronic acid, G) linked by 1,4-glycosidic bonds and composed of different fragments (MM segment, The oligosaccharides composed of GG segment and MG segment) have the advantages of small relative molecular weight and strong absorption. Sodium alginate oligosaccharides have a certain regulatory function on plant growth and development, and have significant effects on plant stress resistance and quality improvement. Oligosaccharides have the functions of inducing plant resistance and promoting plant growth. However, there are no literature and patent reports on the research, development and application of the above-mentioned oligosaccharides as florescence prolonging agents. Oligosaccharides are derived from natural products and have the characteristics of safety, environmental protection, and low residue. They are used as flowering extenders and have advantages over other methods. At the same time, it also has the advantages of low cost and small application amount, and has broad application prospects.
