技术领域technical field
本发明涉及一种鲜切花保鲜剂，具体说是一种可以保持切花在水中新鲜，不凋零的保鲜剂。The invention relates to a fresh-cut flower preservative, in particular to a fresh-keeping agent which can keep cut flowers fresh in water without withering.
背景技术Background technique
在家里养点花不仅能增添生活情趣，使生命更富生机，还能稗益身心健康，陶冶高尚情操，激发对生活的情感。伴随时代的进步，切花养殖越来越受到欢迎，作为欣赏之物进入了千家万户。Growing some flowers at home can not only add interest to life and make life more vibrant, but also benefit physical and mental health, cultivate noble sentiments, and stimulate emotions for life. With the progress of the times, cut flower cultivation has become more and more popular, and it has entered thousands of households as an object of appreciation.
鲜切花在纯水中养殖，花期很短，易弯头，易干枯，叶子易变软发黄等，水体易发霉变浊有臭味。在水中加入保鲜剂，可以改善这些问题，如何提高保鲜剂的效果是从业人员期待的事。Fresh cut flowers are cultivated in pure water, the flowering period is very short, easy to bend, easy to dry, and the leaves are easy to become soft and yellow, etc. The water body is prone to mold, turbidity and odor. Adding preservatives to water can improve these problems. How to improve the effect of preservatives is what practitioners look forward to.
代建丽等人以蔗糖、8-羟基喹啉、柠檬酸为保鲜剂的基本配方，分别加入CaCl2、NaCl、Al2(SO4)3配成的营养液对玫瑰切花保鲜效果明显优于自来水，但8-羟基喹啉毒性作用较大，国外已禁用，不适合作为杀菌剂。仇燕等人以蔗糖、8-羟基喹啉、无水乙醇、抗坏血酸、硝酸钾为主要成分制成的保鲜剂是液体，不便于运输，同样所用的8-羟基喹啉不适合做杀菌剂。陈建辉等人以蔗糖为营养成分，以矮壮素为生长调节剂，以苯甲酸钠作为杀菌剂制备的保鲜剂杀菌效果较弱，保鲜剂保存时间短且保鲜效果也不佳。这些保鲜剂有一定的作用，但普遍存在效果不理想，如易弯头、易干枯、叶子易变软发黄等；部分切花营养液富营养化，使用一段时间水体易发霉变浊有臭味。这些保鲜剂一般可以使玫瑰切花保鲜期延长9天左右。配制保鲜效果更好，保鲜期更长的保鲜剂是值得期待的事。Dai Jianli and others took sucrose, 8-hydroxyquinoline, and citric acid as the basic formula of preservatives, and added CaCl 2 , NaCl, Al 2 (SO 4 ) 3 respectively to the nutrient solution made of nutrient solution, which had a better fresh-keeping effect on rose cut flowers than Tap water, but 8-hydroxyquinoline is highly toxic and has been banned abroad, so it is not suitable as a fungicide. The antistaling agent made by Qiu Yan and others with sucrose, 8-hydroxyquinoline, absolute ethanol, ascorbic acid, and potassium nitrate as the main components is liquid, which is not convenient for transportation. The same 8-hydroxyquinoline used is not suitable as a fungicide. Chen Jianhui and others used sucrose as a nutrient component, chlormequat as a growth regulator, and sodium benzoate as a bactericide to prepare a preservative with weak bactericidal effect, short storage time and poor fresh-keeping effect. These preservatives have a certain effect, but the general effect is not ideal, such as easy to bend, easy to dry, easy to become soft and yellow leaves, etc.; some cut flower nutrient solutions are eutrophic, and the water body is prone to mold, turbidity and odor after a period of use. taste. These preservatives can generally extend the fresh-keeping period of cut roses by about 9 days. It is worth looking forward to formulating a preservative with better fresh-keeping effect and longer fresh-keeping period.

具体实施方法Specific implementation method
以下结合具体实施例对本申请进行示例性说明和进一步理解，但实施例仅作为例子给出，不视为本发明的全部技术方案，不是对本发明总的技术方案的限定。凡具有相同或相似技术特征，简单改变或替换的，均属本发明保护范围。The present application is illustrated and further understood in conjunction with specific examples below, but the examples are given only as examples, and are not regarded as all technical solutions of the present invention, nor are they intended to limit the general technical solutions of the present invention. Those with the same or similar technical features, which are simply changed or replaced, all belong to the protection scope of the present invention.
实施例Example
按照表1所示的配方配好保鲜液，其中1#、2#、3#为按本专利配方配制的保鲜剂溶于水制备的，4#为按文献配方配制的保鲜剂溶于水制备。为了更加明显的表现出本发明保鲜剂的优异效果，5#为不加任何保鲜剂，只有水作为空白的保鲜液。将配好的保鲜液投入细口花瓶中，将处理好的鲜切花插入瓶中。在温度、光照、通风条件较好的地方，观察各个配方的保鲜效果。具体保鲜效果见表2。Preservative solution is prepared according to the formula shown in table 1, wherein 1 # , 2 # , 3 # are prepared by dissolving the preservative prepared by this patent formula, and 4 # are prepared by dissolving the preservative prepared by the document formula . In order to show the excellent effect of the antistaling agent of the present invention more obviously, 5 # is without adding any antistaling agent, and only has water as a blank antistaling solution. Put the prepared fresh-keeping solution into a thin-mouthed vase, and insert the treated fresh-cut flowers into the bottle. In a place with good temperature, light and ventilation conditions, observe the fresh-keeping effect of each formula. The specific fresh-keeping effect is shown in Table 2.
表1实验用保鲜液Table 1 Preservative solution for experiments
备注：对比配方中4#是按文献的鲜切花保鲜剂配方配制的。1#～4#按配方称量好之后溶于水中，均配成0.5L的保鲜液，待用。Remarks: 4 # in the comparative formula is formulated according to the fresh cut flower preservative formula in the literature. 1 # ~ 4 # are weighed according to the formula, dissolved in water, and made into 0.5L fresh-keeping solution for use.
表2每组鲜切花变化现象Table 2 Changes of fresh cut flowers in each group
续表Continuation
备注：(1)“——”表示切花枯萎，弯头，变黄，已失去欣赏价值；Remarks: (1) "——" means that the cut flowers are withered, bent, turned yellow, and have lost their appreciation value;
(2)各组实验使用的保鲜液，随着时间的延长逐渐变少，每隔三日需加200mL静置(2) The preservative solution used in each group of experiments gradually decreases as time goes on, and 200mL needs to be added every three days to let it stand
24h的自来水补充水分。24h tap water to replenish moisture.
上述表2中各组实验所用保鲜剂做对比的现象说明，无论在花朵枝叶上，还是在保鲜剂澄清度随时间变化上，本发明的鲜切花保鲜剂使用效果都明显优于自来水和已有的保鲜剂，尤其是3#使用复合杀菌剂时，更明显的延长了鲜切花的寿命，延迟了鲜切花衰败时间。已有的鲜切花插瓶寿命均在8～9天，使用过程中易发霉发臭，而本发明的营养液可使其寿命达到12～13天之久，且在使用过程中不须更换，可一直保持澄清透明状态。In the above-mentioned table 2, the used preservatives of each group of experiments are compared, and no matter on the branches and leaves of the flowers, or on the change of the clarity of the preservatives with time, the use effect of the fresh-cut flower preservatives of the present invention is obviously better than that of tap water and the existing ones. Preservatives, especially when compound fungicides are used in 3 # , can significantly prolong the life of fresh-cut flowers and delay the decay time of fresh-cut flowers. The lifespan of existing fresh-cut flower vases is 8-9 days, and it is easy to get moldy and smelly during use, but the nutrient solution of the present invention can make its lifespan reach 12-13 days, and it does not need to be replaced during use. Can remain clear and transparent all the time.
