Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of pitaya planting, and particularly relates to a growth regulator for improving the quality of pitaya fruits and a method for applying the growth regulator. BACKGROUND
[0002] Pitaya is a precious variety in the pitaya family, and is also called Qilin fruit due to its yellow skin with white flesh and thorns. It inherits the rich nutritional genes of pitaya and is rich in rare plant albumin, strong antioxidant anthocyanin and high water-soluble dietary fiber. Due to its crystal flesh, sweet and dense taste and its similarity to bird's nest, pitaya is loved by high-end consumers in China.
[0003] Since pitaya is introduced into China for a short time, only small-scale commercial planting is realized in Hainan, Guangxi, Yunnan and Guangdong of China, and in addition, there are few research reports on pitaya, and most of the growers know little about the characteristics of pitaya. In addition, pitaya requires a large amount of labor and the cultivation technology is backward during the whole planting growth period, compared with other economic crops, which leads to uneven quality of the produced pitaya fruits.
[0004] In order to improve the quality of pitaya, the present application provides a growth regulator for improving the quality of pitaya fruits and a method for applying the growth regulator. SUMMARY
[0005] The present application aims at solving the defects in the prior art and provides a growth regulator for improving the quality of pitaya fruits and a method for applying the growth regulator, which can improve the weight or soluble sugar content of pitaya fruits.
[0006] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme:
[0007] The growth regulator for improving the quality of pitaya fruits is mainly composed of the following components by weight: gibberellin GA3 1.33-4 mg / L+naphthalene acetic acid 6.67-20 mg / L or benzylaminopurine 12-36 mg / L+gibberellic acid GA4+GA7 12-36 mg / L or 14-hydroxy-phytosterol 0.067-0.2 mg / L.
[0008] Preferably, the growth regulator is prepared by the following method:
[0009] S1. Each component is weighed according to the weight ratio;
[0010] S2. The gibberellin GA3 and naphthalene acetic acid or benzylaminopurine and gibberellic acid GA4+GA7 or 14-hydroxy-phytosterol powder are respectively dissolved in an organic solvent, and water is added for dilution to obtain a working solution.
[0011] Preferably, the organic solvent is anhydrous ethanol.
[0012] The application also provides a method for applying a growth regulator to improve the quality of fruits of Vaccinium bracteatum. The growth regulator is sprayed on the surface of flowers or fruits to be evenly covered with mist droplets at the evening of the full flowering stage and 7-52 days after pollination or only 7-52 days after pollination. The growth regulator is sprayed 7 days after pollination, and the following three times are all spaced 15 days apart, for a total of 4-5 times during the whole flowering period to fruit period.
[0013] Preferably, the spraying time of the biological regulator for improving the sugar content of fruits of Vaccinium bracteatum is 7-52 days after pollination. The first spraying is performed at the full flowering stage, the second spraying is performed 7 days after pollination, and the following three times are all spaced 15 days apart, for a total of 5 times during the whole flowering period to fruit period.
[0014] Preferably, the spraying time of the biological regulator for improving the weight of fruits of Vaccinium bracteatum is 7-52 days after pollination. The first spraying is performed 7 days after pollination, and the following three times are all spaced 15 days apart, for a total of 4 times during the whole flowering period to fruit period.
[0015] Compared with the prior art, the application has the following beneficial effects:
[0016] After the fruits of Vaccinium bracteatum are treated by the growth regulator for improving the quality of fruits of Vaccinium bracteatum and the method for applying the growth regulator, the quality of the fruits of Vaccinium bracteatum is significantly improved. The average weight of a single fruit is 225.54 g before treatment, and the highest average weight of a single fruit after treatment is 262.65 g, which is increased by 16.45% compared with the weight of the fruit before treatment. The average sugar content of the fruits is 18.1% before treatment, and the highest average sugar content of the fruits after treatment is 20.75%, which is increased by 14.64% compared with the sugar content of the fruits before treatment.

[0068] Table 1 Edgeworthia papyrifera fruit weight and sugar content
[0069] In Table 1, CK (control group) is the same batch of Edgeworthia papyrifera without any treatment.
[0070] Planting results:
[0071] Comparing the average fruit weight data of the non-flower-spraying examples 1, 3, 5, 7, 9, 11, 13, 15, 17 with the flower-spraying examples 2, 4, 6, 8, 10, 12, 14, 16, 18, except for examples 17 and 18, the average fruit weight of the growth regulator flower-spraying is higher than that of the non-flower-spraying.
[0072] From the average fruit weight data of Table 1, it can be seen that, except for Examples 16 and 17, spraying the growth regulator can increase the fruit weight, and the optimal group is Example 1, with an average fruit weight of 262.65 g, which is 37.11 g higher than the average fruit weight of the control group, an increase of 16.45%.
[0073] From the average sugar content data of Examples 1, 3, 5, 7, 9, 11, 13, 15, and 17 without spraying the flowers, compared with Examples 2, 4, 6, 8, 10, 12, 14, 16, and 18 with spraying the flowers, it can be seen that the average fruit sugar content with spraying the flowers is higher than that without spraying the flowers.
[0074] From the average fruit sugar content data of Table 1, it can be seen that spraying the growth regulator during the flowering period can increase the fruit sugar content, and the optimal group is Example 16, with an average fruit sugar content of 20.75 g, which is 2.65% higher than the average fruit sugar content of the control group, an increase of 14.64%.
