Tea tree dormancy breaking agent as well as preparation method and application of tea tree dormancy breaking agent

Abstract

The invention relates to a tea tree dormancy breaking agent as well as a preparation method and an application of the tree dormancy breaking agent and belongs to the field of tea leaf cultivation. Aiming to solve the technical problems, the invention provides the tea tree dormancy breaking agent which is safe and has a good dormancy breaking effect, and the application of the tree dormancy breaking agent. According to the tea tree dormancy breaking agent, an active component is prepared by following steps: a, adding glycerol into a solution containing NO<3-> and Ca<2+> and chelating at 80-100 DEG C for 0.5-4 hours; and b, cooling and adding urea to obtain the active component, wherein the mol ratio of the NO<3-> to the Ca<2+> to the glycerol is (20-55) to (6-10) to 13 and the mol ratio of the urea to the glycerol is (15-28) to 13. The invention further discloses the application of the tea tree dormancy breaking agent in the aspect of promoting the breaking of dormancy of tea trees. According to the tea tree dormancy breaking agent, all the components are harmless to a human body and the environment; complicated chemical components are not added and the residue of hormones is not caused; a safety problem is not caused; meanwhile, the tea tree dormancy breaking agent has the advantages of good dormancy breaking effect and the like.

Description

technical field [0001] The invention relates to a tea tree sleep breaker, a preparation method and application thereof, and belongs to the field of tea cultivation. Background technique [0002] Tea tree is a perennial plant, which has the characteristics of overwintering and dormancy in most tea areas, and the new shoots of tea trees that grow naturally have 3 to 4 times of "growth-rest" rotation characteristics in the annual development cycle. A biological adaptation that is beneficial to environmental conditions and seasonal exchange acquired through long-term evolution. Tea tree is a kind of economic crop mainly using leaves, the growth and cessation of its buds and leaves are not only related to its adaptability to environmental conditions, but also related to its economic value. If the dormancy time in winter can be shortened and the rounds of new shoot germination can be increased, the annual output of tea leaves will be greatly increased. [0003] At present, most ...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the researches on sleep-breakers focus on fruit tree sleep-breakers, and there are few studies on tea tree sleep-breakers.

As for tea trees, a relatively special plant, not only dormancy occurs in winter, but also there are periodic "growth-rest" wheel characteristics in the annual cycle. At present, most of the research on tea tree wheel sex is just speculation, and further research is needed. It has been confirmed that the research on tea tree dormancy in winter mainly focuses on the external environmental conditions and hormone levels. At present, more ways to help tea trees break dormancy are to apply general fruit tree dormancy agents to tea trees, although it will also break dormancy for tea trees. It is helpful to a certain extent, but it has not achieved very good results. At the same time, there are chemical residues in general fruit tree sleep breakers, which are harmful to the human body and other problems.
