Detailed Description
The following further describes the embodiments of the present invention. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Example 1
The reagent used is nano titanium dioxide (nTiO)2): under the observation of 20 ten thousand times of magnification, the nano titanium dioxide sample is particles with about 1-80nm and uniform size, the appearance is basically consistent, the surface is nearly circular, only a small amount of particles are agglomerated, and the dispersibility is good. Adding a small amount of clear water into the hydrophilic nano titanium dioxide, placing the hydrophilic nano titanium dioxide into an ultrasonic machine, performing ultrasonic dispersion for 10min under the conditions that the ultrasonic power is 500w and the ultrasonic frequency is 20kHz, and preparing the hydrophilic nano titanium dioxide into a 300mg/L nano titanium dioxide solution by using water.
Collecting pollen of male flowers manually in the flowering period of the litchi, and picking up the male flowers with the whole small flowers (the anthers are white) after the cut flower ears are collected. The removed male flowers are placed into a test sieve with the diameter of 20cm and the diameter of 150-. And slightly shaking the sieve to enable the pollen to fall onto the parchment paper through the sieve holes. Subpackaging the collected pollen into 1.5ml centrifuge tubes, sealing with film sealing tape, storing in sealed bag containing silica gel, and storing in-80 deg.C refrigerator.
Dissolving the collected litchi pollen in a prepared nano titanium dioxide solution, wherein the mass concentration of the pollen is 0.1g/L, carrying out artificial pollination in a sunny clearance, and completely spraying the prepared pollen nano titanium dioxide solution within half an hour. And investigating indexes such as fruit setting rate change, final fruit setting amount, fruit size, fruit quality and the like. A blank control (CK, same amount of pollen dissolved in same volume of clear water) was also set.
Comparative example 1
Collecting male flower pollen in the flowering phase of litchi artificially, and dissolving in the following solutions: 15L of water, 7.5g of calcium nitrate, 1.5g of boric acid, 1.5g of zinc sulfate, 500g of sucrose and 15ml of Tween, the amount of pollen, the volume ratio of the solution and other operations were the same as in example 1.
Effect verification:
1) initial fruit set rate
The initial fruit setting amount of the osmanthus flavor treated trees is close to that of the control trees in 5 days after the female flowers open, and TiO is sprayed at 47-50 per ear in 12 days and 19 days after the female flowers2Adding pollenThe fruit setting rate of the treatment is 46.68% + -7.14% and 30.33% + -4.2% respectively, which is higher than that of boric acid and a control group. The initial fruit set was between 50-61 for the wafers treated and the control trees, which were slightly higher than the treated trees, but the females were open for 12 and 19 days, and the fruit set was higher for both groups of treated trees (Table 1). Litchi pollen combined with nano-grade TiO can be seen2Or B + ZuSO4+CaCl2+ artificial pollination with Sucross water solution can improve cassia taste and glutinous rice cake fruit setting in the early stage and nanometer level TiO2The treatment is characterized in that the effects of the sweet osmanthus and the glutinous rice cake are more stable.

2) Change in fruit set rate
The 'cinnamon flavor' fruit setting rate is in nano TiO level2The content of the boric acid in the treated tree is remarkably higher than that of the control tree within 7-53 days after treatment, the content of the boric acid in the treated tree is not obviously different from that of the control tree within 7-42 days after the treatment of the boric acid, and the content of the boric acid in the treated tree is remarkably higher than that of the control tree within 14-53 days. The 'Nuomici' fruit setting rate is in nano TiO level2The ratio of the boron acid to the boric acid is obviously higher than that of the control tree within 21 days after the treatment, and is slightly higher than that of the control tree within 7-53 days after the boric acid treatment, but no obvious difference exists. As shown by the results, litchi pollen is combined with nano-scale TiO2Or B + ZuSO4+CaCl2+ artificial pollination with Sucrose water solution can improve the osmanthus fruit setting rate well, and nanometer TiO level2The effect of the treatment is more stable (fig. 1).
3) The whole plant bears fruit amount in the phenological process and mature period

4) Fruit quality
Litchi pollen combined with nano-grade TiO2After treatment, the weight of the 'osmanthus-flavored' single fruit is heavy, the titratable acid-solid acid ratio is not different from that of a control, and the edible rate, the soluble solid content and the vitamin C content are reduced; the weight of each glutinous rice cake single fruit, the edibility rate, the content of soluble solids, titratable acid and vitamin C are obviously higher than those of a control, and the solid-acid ratio is obviously lower than that of the control (figures 4-8). After the litchi pollen is treated by combining boric acid and the like, the weight of a single osmanthus-flavored fruit is not different from that of a control, the edibility rate, the content of titratable acid and the content of vitamin C are obviously higher than that of the control, and the solid-acid ratio is obviously lower than that of the control; the dietary rate and the soluble solid content of the glutinous rice cake are not different from those of a control, the content of single fruit weight, titratable acid and vitamin C is obviously higher than that of the control, and the solid-acid ratio is obviously lower than that of the control (figures 4-8). Compared with the results after boric acid treatment and the like, the nano-scale TiO2The treatment effect is more obvious.
5) Color of fruit
The results in Table 2 show that the fruits of litchi, such as sweet osmanthus and glutinous rice cake, are subjected to nano-scale TiO processing, and the fruits of litchi are subjected to color difference measurement, wherein the color difference measurement is carried out by a colorimeter to obtain the lightness values L (from black to white, 0-100, the red-green chroma a (from green to red, -a to + a), the yellow-blue chroma b (from blue to yellow, -b to + b), the C (chroma values, which reflect the concentration of pigments) and h (hue values to determine the colors of red, yellow, green, blue, purple and the like and the colors among the basic colors)2After the solution treatment, the color of the peel is darker red than that of the control group, the color is more saturated, and the hue is obviously different from that of the control group. Nano-sized TiO 22The color of the peel treated by the solution has a plurality of indexes superior to those of the treated group such as boric acid.
TABLE 2 Effect of different reagent treatments on litchi fruit color
In conclusion, litchi pollen is combined with nano-scale TiO2The processing can improve the edible rate, the soluble solid content and the vitamin C content of the sweet osmanthus glutinous rice cake fruits and improve the fruit quality. The vitamin C content of the sweet-scented osmanthus glutinous rice cakes is obviously increased after treatment by boric acid and the like. Both treatments can improve 'glutinous rice cake'Single fruit weight of, nano-scale TiO2The treatment effect is more obvious. Nano-sized TiO 22After the solution treatment, the color of the peel is darker red than that of a control group, the color is more saturated, the hue is obviously different from that of the control group, and multiple indexes of the peel color are superior to those of a boric acid treatment group.
