Embodiment 1～ Embodiment 3
[0058] Examples 1 to 3 involve the early intervention method of flower preservation and fruit preservation of Kumquat kumquats, and the exogenous hormone formula adopts the first formula, and the specific composition of the first formula and the content of the test drug are shown in Table 1.
[0059] The application method of the first formula comprises the following steps:
[0060] The first spraying: When the flowers are about to open, spray the whole plant evenly with agent A once;
[0061] The second spraying: after shaking the flowers, that is, within 3 days after the flowers fade, spray the whole plant evenly with B agent once;
[0062] The third spraying: 5 to 6 days after the second spraying, spray the whole plant evenly with agent B once;
[0063] The 4th spraying: 10 to 15 days after the 3rd spraying, spray the whole plant evenly with agent B once.
Embodiment 4～ Embodiment 6
[0065] The kumquat kumquat of this embodiment is involved in the flower and fruit preservation method in advance, and the exogenous hormone formula adopts the second formula, and the specific composition of the second formula and the content of the test agent are shown in Table 1.
[0066] The method for administering the second formula comprises the following steps:
[0067] The first spraying: When the flowers are about to open, spray the whole plant evenly with C agent once;
[0068] The second spraying: After shaking the flowers, that is, within 3 days after the flowers fade, use the D agent to spray the whole plant evenly once;
[0069] The third spraying: 3 to 4 days after the second spraying, spray the whole plant evenly with D agent once;
[0070] The 4th spraying: 4 to 5 days after the 3rd spraying, spray the whole plant evenly with D agent once.
[0071] Table 1 shows the composition and test drug content of the crisp honey kumquats of Examples 1 to 6 for early int...

Abstract
The invention provides a method for early intervention of flower and fruit retention of crisp and honey kumquats. According to the method, pesticide is applied by adopting different exogenous hormone formulas during flowering and fruit setting periods of the crisp and honey kumquats. The method comprises the following steps that (1), early intervention of flower and fruit retention is carried out, specifically, when flowers are about to bloom, the corresponding exogenous hormone formula is sprayed for the first time to protect the flowers, so that flower buds are not subjected to blooming, pollination and fertilization, the ovary develops and grows towards fruit setting; and (2), fruit protection is carried out after flower falling, after flower falling, a corresponding formula is sprayed for the second time to protect flowers and fruits, and then, third spraying and fourth spraying are carried out according to a corresponding exogenous hormone formula and spraying time so as to protect fruits. According to the method for early intervention of flower and fruit retention of the crisp and honey kumquats, exogenous hormones are used for promoting fruit setting of the first batch of flowers and the second batch of flowers, the fruit setting rate can be increased to 34.4%-242.7%, the flower-protecting effect and the fruit-protecting effect are achieved, and the yield-increasing and synergistic effects are obvious.
Description
technical field [0001] The invention relates to the technical field of fruit tree cultivation, in particular to an early intervention method for preserving flowers and fruits of kumquat kumquats. Background technique [0002] Crispy honey kumquat is one of the few polyploid fruit tree varieties known to be artificially cultivated. Crispy honey kumquat is excellent in both internal quality and external commerciality, and has a high degree of market recognition. It is a good product among fresh fruits . Crispy honey kumquat has been promoted as a premium product of geographical indication products in Rong'an County, Liuzhou City, and the planting scale has been expanded. But there is a characteristic: in the natural state, the first and second batches of flowers have a very low natural fruit-setting rate, but the fruits are naturally ripe and of excellent quality, and the market time is during New Year's Day and Spring Festival, and the sales market is good, while the third b...
