protecting the golden tribute shaddock trees from being frozen in winter and keeping the golden tribute shaddock trees at the temperature of more than-2 ℃;
and fourthly, strengthening the fruits, applying sufficient fertilizer to ensure the nutrient elements for the growth of the Huangjinggong pomelo fruits and preventing and treating plant diseases and insect pests when the fruits enter the mature period in spring of the next year, so that the Huangjinggong pomelo fruits can be mature in 7-8 months.
Further, the plant growth regulator for spraying buds to ensure that all normal flowers fall off adopts one or more of 2, 4-dichlorophenoxyacetic acid, naphthylacetic acid and indolebutyric acid.
Further, when the flower buds of the golden tribute pomelos appear white in the beginning of 3-4 months, the flower buds are sprayed with 500-800 times of 2, 4-dichlorophenoxyacetic acid liquid, so that normal flowers fall off completely.
Further, the plant growth regulator for inducing flowering is one or more of indoleacetic acid, naphthylacetic acid, ethephon and chlormequat chloride.
Further, after spring shoots are aged, 800-1000 ppm of indoleacetic acid and 500ppm of naphthylacetic acid are sprayed at the beginning of 5-6 months for inducing flowering.
Further, the golden tribute pomelo trees can be kept warm by using a greenhouse or in a peritoneal mode during overwintering.
Furthermore, during the secondary flowering, fruiting and fruit expansion process of the Huangjingong pomelo tree, sufficient fertilizer is applied to ensure the nutrient elements for the growth of Huangjingong pomelo fruits and prevent and treat plant diseases and insect pests.
Furthermore, in the fruit-strengthening period in the spring of the second year, a plant growth regulator capable of promoting or delaying fruit ripening is sprayed, so that the fruit ripening of the Huangjingong pomelo can be promoted or delayed, and the fruit ripening period of the Huangjingong pomelo can be adjusted.
Further, the plant growth regulator for promoting fruit ripening can be one or more of forchlorfenuron, compound sodium nitrophenolate, ethephon and daminozide, and is prepared into a concentration capable of promoting fruit ripening.
Furthermore, the plant growth regulator for delaying fruit ripening can be one or more of 2, 4-dichlorophenoxyacetic acid, gibberellin, daminozide, kinetin, naphthylacetic acid and 6-benzylaminopurine, and is prepared into a concentration capable of delaying fruit ripening.
As can be seen from the above description of the present invention, compared with the prior art, the beneficial effects of the present invention are:
the method breaks through the technical bottleneck, and by inducing the golden tribute pomelos to bloom for the second time and utilizing the second time to blossom and bear fruits, the golden tribute pomelos can be ripe in 7-8 months, so that the annual supply of fresh citrus fruits is realized; the ripening period of the fruits can be determined according to the time of the secondary flowering and fruiting, so that the time for supplying fresh citrus fruits is adjusted, and the method has remarkable social and economic benefits.
