It is to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
In addition, for numerical ranges in this disclosure, it is understood that each intermediate value between the upper and lower limits of the ranges is also specifically disclosed. Every smaller range between any stated value or stated range, and any other stated value or intermediate value within the stated range, is also encompassed within the invention. The upper and lower limits of these smaller ranges may independently be included or excluded in the range.
Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. Although only preferred methods and materials are described herein, any methods and materials similar or equivalent to those described herein can be used in the practice or testing of the present invention.
As used herein, the terms "comprising," "including," "having," "containing," and the like are intended to be inclusive and mean an inclusion, but not limited to.
The invention provides a growth regulator for improving the strontium content of blueberry fruits, which comprises the following components: surfactant, strontium nitrate, auxin and water; the auxin is one or two of indoleacetic acid and indolebutyric acid.
The growth regulator provided by the invention has the advantages that the growth performance of blueberries can be improved, and the strontium absorption capacity of blueberry fruits in the fruit setting period of the blueberries can be greatly improved, so that the mature blueberry fruits have high strontium content.
Further, the concentration of the surfactant is 0.25 to 0.5 wt%; the concentration of the strontium nitrate is 5-10 mg/L; the concentration of the auxin is 50-100 mg/L.
Further, the surfactant is triton X100 (commercially available variety).
Further, the auxin is indolebutyric acid or a combination of indolebutyric acid and indolebutyric acid.
Compared with indoleacetic acid, indolebutyric acid or indoleacetic acid+indolebutyric acid can further improve the strontium content in blueberry fruits.
Further, the auxin is indoleacetic acid and indolebutyric acid.
Compared with the single use of indoleacetic acid or indolebutyric acid, the combination of the indoleacetic acid and the indolebutyric acid is used as auxin, so that the strontium content in mature blueberry fruits can be improved more remarkably, and the effect shows that the combination of the indoleacetic acid and the indolebutyric acid can play a synergistic addition role in the strontium absorption of blueberries.
The invention also provides a preparation method of the growth regulator for improving the strontium content of the blueberry fruits, which comprises the following steps: dissolving auxin in organic solvent, and mixing with surfactant, strontium nitrate and water to obtain the growth regulator for increasing strontium content in blueberry fruit.
Further, the organic solvent is ethanol, and the added ethanol can meet the requirement of dissolving the auxin.
The purpose of adding the organic solvent to dissolve the auxin is as follows: auxins are generally not highly soluble in water, and therefore it is necessary to dissolve auxins in advance using a solvent having a large solubility.
The invention also provides application of the growth regulator for improving the strontium content of the blueberry fruits in blueberry planting.
Furthermore, the application period of the growth regulator for improving the strontium content of the blueberry fruits is the blueberry fruit setting period (21-45 d after the blueberry flowers are filled), and the application mode is whole plant spraying.

The effect of the growth regulators prepared in examples 1 to 8 on the growth of blueberries was examined, and water was used as a control group.
The method is characterized in that the 'brilliant' rabbit eye blueberry variety is selected as an experimental variety, and the whole blueberry plant is sprayed by using a watering can after 21 days and 45 days of the full bloom period respectively, and when the whole blueberry plant leaves are wrapped by liquid, the spraying is stopped. 3 strains were replicated for each treatment. 50 fruits are randomly harvested in three directions on the upper part and the lower part of the tree body respectively for each treated single plant after the fruits are completely colored to full blue, the maximum diameter of the fruits, the strontium content of the fruits and the soluble solid indexes are analyzed, and the analysis results are shown in Table 1.
TABLE 1 effects of different treatments on strontium content of blueberry fruit, maximum fruit diameter, soluble solids
Remarks: the different lowercase letters in the same column in Table 1 represent the difference limits.
As can be seen from table 1, the strontium content in the blueberry fruit can be increased by spraying strontium (examples 1 to 8 versus water); the addition of auxin to the growth regulator can further increase the strontium content in the blueberry fruit and also has an effect of increasing the fruit diameter (comparative example 1 and examples 3 to 6); in addition, indolebutyric acid or a combination of indolebutyric acid and indolebutyric acid can further increase the strontium content in blueberry fruit as compared to indolebutyric acid (comparative examples 3, 4, 6); compared with the single use of indoleacetic acid or indolebutyric acid, the combination of the indoleacetic acid and the indolebutyric acid is used as auxin, the content of strontium in mature blueberry fruits can be improved more remarkably (comparative examples 3, 4 and 6), and the effect shows that the combination of the indoleacetic acid and the indolebutyric acid can play a synergistic addition role on the strontium absorption of blueberries.
The above embodiments are only illustrative of the preferred embodiments of the present invention and are not intended to limit the scope of the present invention, and various modifications and improvements made by those skilled in the art to the technical solutions of the present invention should fall within the protection scope defined by the claims of the present invention without departing from the design spirit of the present invention.
