Test example 1Fresh-keeping effect measurement
1. Measurement index and method
(1) Average diameter of flowers
From the day of bottle insertion, each treated flower diameter was measured with a vernier caliper every 8d, and the flower diameter was represented by the maximum value of the flower diameter.
(2) Fresh weight change rate of cut flowers
From the time of inserting the cut flowers into the bottle, the fresh weight of the cut flowers was measured every 8d with an analytical balance. The calculation formula is as follows:
fresh weight change rate= (nth day fresh weight-initial fresh weight)/initial fresh weight x 100%.
The weight of the rose branches is measured by an electronic balance at fixed time every 2d from the cut flower vase to the end of the vase life by adopting a weighing method. The fresh weight change rate during bottle insertion was calculated with the fresh weight at the beginning of the treatment being 100%.
(3) Sensory photo
Shooting by using a single phase inverter.
(4) Cut vase life
After harvesting and bottle inserting of cut rose, observing and recording the ornamental quality of the cut rose every 8d, wherein the ornamental quality is divided according to the 1 st part of the GBT18247.1-2000 main flower product grade: cut flower rose standard of cut flowers takes the serious wilting of flowers, withered and shrunken petals, darkened flower color, withered stems, elbows and the like as the standard for judging that the cut flowers lose ornamental value, and the cut flowers lose ornamental value, namely the end of the life of bottle plug.
(5) Flowering index
Flowering index 1: the calyx is slightly loose, so that the method is suitable for long-distance transportation;
flowering index 2: the calyx extends out of the sepal, and can be used for long-distance and short-distance transportation;
flowering index 3: the petals of the outer layer start to loosen, so that the flower pot is suitable for close-range transportation or close sales;
flowering index 4: the petals of the inner layer start to loosen and must be sold nearby.
The flowering index calculation formula is:
flowering index = Σ (flowering level×this level of flowers)/(highest flowering level×total flowers) ×100%
(6) Rate of decay
The flower rot area is divided into 4 grades:
1 grade, the rotten area is less than 10% of the area of the flower;
2, the rotting area accounts for 10% -30% of the area of the flower;
the decay rate calculation formula is:
decay Rate = Σ (decay level×this level of flowers)/(highest decay level×total flowers) ×100%
(7) Flower stem withering index
Observing the shape of the flower stems and the flower heads:
stage 1: the bending phenomenon is avoided, and the device is in an upright state;
2 stages: part of the flower buds are bent and are easy to bend;
3 stages: flower buds are curved and have a partial open flower curvature, which is a severe curvature.
The calculating formula of the flower stem wilt index is as follows:
withering index = Σ (withering grade×this grade of flowers)/(highest withering grade×total flowers) ×100%
2. Results and analysis
After the cut flowers were subjected to fresh-keeping treatment in accordance with the methods of examples 1-2 and comparative examples 1-7, the cut flowers were measured for 40d every 8 days in accordance with the above-mentioned measurement index and method. The fresh-keeping effect of the fresh flowers is measured according to the measurement indexes and the method, and the specific results are shown below.
(1) Sensory photo of different treated fresh flowers
As can be taken from fig. 1, the cut rose flowers of comparative examples 1 to 7 had already appeared to wilt and neck at the time of cold storage 32 d; the bottle inserting effect of the rose cut flowers of the treatment groups of examples 1-2 of the refrigerating 40d is still better. The treatments of examples 1-2 are shown to be more effective in inhibiting the senescence of cut rose flowers than the other treatment groups.
(2) Influence of different treatments on the weight loss rate of fresh flowers
As can be seen from fig. 2, the trend of change was the same for all treatment groups, and the weight loss rate of rose cut flowers increased with the increase of the refrigerating time. The weight loss rates of the cut flowers of China rose of the example 1 and the example 2 are significantly lower than those of the treatment groups of the comparative examples 1 to 7 in the whole, which shows that the treatment of the example 1 and the example 2 can delay the aging of fresh flowers.
(3) Influence of different treatments on the decay rate of fresh flowers
As can be seen from fig. 3, the rot rate of the cut flowers of China rose increases with the increase of the refrigerating time, and the rot rate of the treatment groups of the embodiment 1 and the embodiment 2 is significantly lower than that of the other treatment groups after the refrigerating for 24d, which means that the treatment of the embodiment 1 and the embodiment 2 can well inhibit the respiration of the cut flowers, delay the increase rate of the rot rate of the China rose, and prolong the bottle plug life.
(4) Effect of different treatments on flowering index
As can be taken from fig. 4, the flowering-index of each group treated as a whole showed a continuously rising trend. Wherein, the flowering index of the example 1 and the example 2 after 16d refrigeration is significantly lower than that of other treatment groups, which indicates that the treatment of the example 1 and the example 2 can slow down the loosening speed of petals and the withering speed of flowers.
(5) Effect of different treatments on wilting index
As can be seen from fig. 5, the wilting index of each group treated as a whole showed a continuously rising trend, and the wilting index of the treatment groups of example 1 and example 2 was significantly lower than that of the other treatment groups. Description of the treatment in the treatment groups of examples 1 and 2 can slow down the withering and decay of flowers and slow down the rate of flower withering.
(6) Effect of different treatments on maximum flower diameter
As can be seen from fig. 6, the maximum flower diameter of each group treated as a whole showed a tendency to decrease continuously, and the maximum flower diameters of the treatment groups of example 1 and example 2 were significantly higher than those of the other treatment groups. Description the treatments of the treatment groups of example 1 and example 2 are able to maintain a larger maximum floral diameter, delaying the senescence of cut flowers.
From the above results, the treatment of example 1 and example 2 can better preserve the weight loss rate and flower diameter of cut rose flowers, reduce the rotting rate and wilting index of cut flowers, and maintain a high ornamental value of flowers in refrigeration 40d. Comparative examples 1 to 7 had a loosening of petals and a bending phenomenon at the time of cold storage for 32 d. In comparative example 1, no humidifying liquid is added in the precooling process for atomization fumigation, so that the ethylene regulation and control effect is affected. In the comparative example 2, atomization fumigation is not performed, and the fresh-keeping effect is lower than that of the humidification liquid of the invention, and then the bacteriostat polylysine solution is used for fumigation after fumigation; in comparative examples 3 to 4, the film sealing agent disclosed by the invention is not adopted, so that the water retention and corrosion resistance of cut flowers are reduced, and the fresh-keeping effect is poor; comparative example 5 where no SO was added 2 The slow-release fresh-keeping tablet affects the subsequent anti-corrosion and fresh-keeping of cut flowers; the compound nutrient solution in this application is not added in comparative example 6~7 for can't be at the very first time after adopting for cut flower supplements moisture and nutrition, influence follow-up fresh-keeping process, and then make final fresh-keeping effect not good enough.
