Embodiment 1

[0054] Embodiment 1, the research of cooling capacity

[0055] The test site is in Guilin, Guangxi. Guilin has a mid-subtropical humid monsoon climate, with a mild climate and abundant rainfall. The annual average temperature is around 19°C. The hottest months are July and August. The monthly average temperature is around 28°C, and the extreme maximum temperature does not exceed 39°C; the coldest month is In January and February, the average temperature is 8-9°C, and the average minimum temperature is not lower than 5°C. There have also been severe cold weather of minus 3-4°C.

[0056] Experimental materials: The main peach trees in Guilin - Beijing No. 1, Tianjin Shuimi and Crisp Sweet Peach, and the discarded peach branches pruned in autumn.

[0057] Experimental drug: Hoagland Solution

[0058] To explore the low temperature requirements of different varieties (Beijing No.1, Tianjin Shuimi and Crispy Sweet Peach) to break dormancy by using low temperature.

[0059] The e...

Embodiment 2

[0066] Embodiment 2, flower forcing and fresh-keeping test

[0067] The experimental site is Beijing Forestry University. The temperature comparison test site is set in the room with heating supply, the hall and corridor of the dormitory building. The test sites for the opening angle of the branches and the fresh-keeping solution are all indoors. The indoor temperature is 19-22 °C, the humidity is 20%-41%, and natural light is scattered.

[0068] Test materials: Beijing No. 1 peach branches, Tianjin juicy peach branches and green peach branches from the campus of Beijing Forestry University collected from the Guilin test site.

[0069] Test drugs: improved Hoagland nutrient solution, S (sucrose, sucrose), 6-BA (6-Benzylaminopurine, 6-benzylaminoadenine, cytokinin), 8-HQ (8-hydroxy-quinoline, 8-hydroxy quinoline)

[0070] To study the temperature and humidity conditions required for flowering, the effect of branch placement angle on the flowering rate of flower buds, and the ...

Embodiment 3

[0099] Embodiment 3, Spring Festival peach cut flower comprehensive control test

[0100] The test site is in Guilin, Guangxi, and the flower forcing and fresh-keeping tests are carried out indoors, with natural light scattering.

[0101] Test material: Beijing No. 1 in the Guilin test site, and the annual growth status of the pruned discarded branches is similar.

[0102] Experimental drug: fresh-keeping solution, configured with the best ingredients and ratios obtained from flower-urging and fresh-keeping tests.

[0103] The amount of cooling required and the most suitable cultivation conditions obtained from the previous research experiments guide the production practice, and use the whole set of control measures to achieve peach blossoms in advance of the Spring Festival and prolong their viewing time.

[0104] Nectarine variety Beijing No. 1 requires a cooling capacity of 384 hours at 5°C, so it needs at least 11 days of low-temperature treatment at 5°C to release dorman...

Abstract

The invention discloses a method for regulating and controlling a flowering phase of peach cut-flowers and guaranteeing the flowering quality. The method for regulating and controlling the flowering phase of peach cut-flowers and guaranteeing the flowering quality disclosed by the invention comprises the following steps: determining a pickup date of the peach cut-flowers according to the selected optimal ornamental date, performing low-temperature treatment according to the chilling requirement after the peach cut-flowers are picked up at the pickup date, obtaining peach cut-flowers in natural dormancy, performing flower forcing treatment, and obtaining the peach cut-flowers in the optimal ornamental period. According to the method disclosed by the invention, the flowering phase on the specified date can be regulated and controlled by combining environmental control according to different chilling requirements of different peach cut-flower qualities, for example, early-maturing varieties are guided to bloom on Christmas Day, New Year's Day and Spring Festival, and late varieties are guided to be in full bloom on May Day even can bloom on each needed festival. The method has significance in promoting development of sightseeing agriculture and Peach Flower Festival and realizing greater social benefits, landscape benefits and economic benefits.

Description

technical field [0001] The invention relates to a method for regulating and controlling the flowering period of peach cut flowers and ensuring flowering quality, and belongs to the field of biotechnology. Background technique [0002] Peach (Prunus persica) originates in China, and is a deciduous small tree of the Rosaceae Prunus subgenus Prunus. The flowering period of peach trees is comprehensively affected by various factors. In order to advance and prolong its flowering period, experts at home and abroad have conducted a lot of research and made some breakthroughs in breeding, chemical regulation, and environmental regulation. [0003] A key factor affecting the flowering period of peach trees and releasing them from dormancy is the cooling capacity. The effective low temperature hours required by deciduous fruit trees to break natural dormancy (internal dormancy) is called the cooling requirement of fruit trees. Low temperature can induce dormancy, and the release of ...
