Description

The method for fast flowering of kumquat plants by temperature regulation

technical field

The invention relates to the field of citrus breeding and cultivation, in particular to a method for quickly forming flowers of kumquat plants through temperature regulation.

Background technique

Citrus, Rutaceae Citrus subfamily plants, there are 3 genera used for economic cultivation: Citrus aurantium, Golden Citrus and Citrus. Citrus has a long history of cultivation in my country. In addition to meeting people's food needs, kumquat citrus such as kumquats and quaters can also be used as ornamental plants. After fruiting, the fruits are golden and plump, which is of great ornamental value. Especially during the Spring Festival, the "auspicious" implication of citrus in Chinese traditional culture has given rise to people's consumption demand for ornamental citrus. The flowering habits of citrus are very different. Most citrus plants bloom once in spring in subtropical regions, while kumquat plants can bloom continuously, and the flowering period is concentrated in summer. The flowering habit of citrus not only restricts the development of cross breeding between citrus genera, but also is not conducive to the production of ornamental citrus during festivals.

The existing main measures for inducing flower bud formation in citrus are low temperature and drought. Kumquat plants such as kumquats and quaters can be induced to flower through natural drought, and flower bud differentiation can also be promoted by controlling irrigation and circumcision in production. However, water control treatment takes a long time, and the operation steps are relatively complicated, and the degree of water control needs to be accurately grasped, otherwise excessive drought will cause leaf fall and affect the growth of plants. Circumcision requires a lot of labor, high cost, low efficiency, and will affect the normal growth and development of the tree.
