Problems solved by technology

In recent years, due to artificially wrong timing or the influence of genetic characteristics, climate and cultivation, etc., the parental flowering period does not meet, resulting in the failure of hybrid breeding. Research on flowering adjustment measures is of great significance for improving the process of citrus hybrid breeding.

Embodiment 1

[0020] The plant regulator formula for delaying the flowering phenophase of citrus and its application method, the steps comprising:

[0021] (1) Appropriate chemical spraying time:

[0022] Select 4-year-old grafted container seedlings of the citrus 'Ehime kashi No.28' variety with no pests and diseases, luxuriant leaf growth and consistent phenological period, about 30 days before its spring germination, that is, February 1, 2021 (the previous germination period in this area At the beginning of March), it is advisable to evenly spray the foliage flowering delay regulator until a small amount of dripping on the crown. Different florescence delay regulator treatments are set at the same time; wherein, each treatment is divided into three repetitions, and each plant is a repetition; then all above-mentioned plants are placed in a light incubator, the temperature is set to 28 ° C, and the humidity control is 70% , 24 hours full light treatment. Spray in the same way after an i...

Abstract

The invention belongs to the technical field of fruit tree cultivation and discloses a plant regulator formula for delaying the flowering phenophase of citrus, which comprises the following components: potassium indole butyrate, ammonium ferric citrate, auxiliary agent and water. The method of the invention can effectively delay the flowering phenology period of citrus, and is convenient for cross-pollination between citrus parents who are not in flowering period. The plant regulator in the invention has reasonable formula, simple and convenient operation, strong practicability, can effectively delay citrus flowering, and is safe and efficient.

Description

technical field [0001] The invention belongs to the technical field of fruit tree cultivation, and discloses a plant regulator for delaying the flowering phenophase of citrus and an application thereof. Background technique [0002] Plant flowering regulation, that is, the use of artificial measures to make the flowering period outside the natural flowering period, so as to control the early or delayed flowering period. In recent years, regulating flowering by spraying hormones has become an important technique in tree cultivation management and has attracted much attention. Related research results show that indole-3-butyric acid (Indole-3-Butyric Acid) is one of the precursors of auxin, which is converted into auxin (Indole-3-Acetic Acid) in the process of peroxisome β-oxidation, Regulating the level of IBA in plants can promote root growth and development. Therefore, at present, IBA, as the main component of rooting agent, can significantly increase the rooting rate of ...
