Abstract
The invention involves the technical field of plant planting and cultivation, specifically a
method for rapidly determining the chilling requirement of peaches. After the peach leaves fall,
collect branches of current year every 4 - 5 days, wherein, the branch length is 20 - 30 cm and
there are more than 20 flower buds and leaf buds on each branch. Then insert these branches
into water for 2 - 3 cm indoors. Cut the lower parts of the peach branches every 3 days to
expose fresh color, and change water every 3 days. When 50% of leaf buds are exposed and
50% of flower buds are blooming, it means that flower buds and leaf buds meet their own
chilling requirement. Adopting the method in this invention, the blossom rate and germination
rate can be counted in only 15 days, and after 15 days, the complete statistics of the blossom
rate and germination rate can be used to determine its chilling requirement, which saves 7 - 13
days compared with the traditional method (21 - 28 days). In addition, there are various
requirements in traditional method, and it is difficult to control the changes of various
conditions. While, the method in this invention has simple determination conditions and
operation.

A method for rapidly determining the chilling requirement of peaches
The invention is described in the following statement:-
A method for rapidly determining the chilling requirement of peaches
The invention relates to the technical field of plant planting and cultivation, specifically
to a method for rapidly determining the chilling requirement of peaches.
The chilling requirement of peach is the accumulation of low temperature at the end of
natural dormancy period. As an inherent characteristic of peach originated in cold
regions, it has a decisive influence on the introduction and cultivation of peach in
southern China.
The chilling requirement refers to the effective low-temperature hours needed to meet the
natural dormancy of deciduous fruit trees, which is usually calculated by the accumulated
hours of experiencing low temperature 0 - 7.2 °C (excluding 0 °C ) after entering
dormancy. Knowing the chilling requirements of varieties can guide the heating time
correctly. Without low temperature satisfied, the peach trees will not germinate normally
even if there are suitable temperature and humidity conditions for germination and
flowering, but appear withered buds, irregular flowering (for a long time) and low fruit
setting percentage causing effects on yield. How to quickly determine the chilling
requirement of peach is of great theoretical and practical significance for peach
cultivation.
Only when the chilling requirement is satisfied in cultivation, can beach blossom and
bear fruit normally in southern China. However, the existing methods for measuring chilling requirement need three or four weeks under certain conditions, which is time consuming and laborious.
The purpose of the present invention is to provide a method for rapidly determining the
chilling requirement of peach, aiming at the problems that the traditional method is time
consuming and laborious.
In order to achieve above purpose, the invention adopts following technical scheme.
A method for quickly measuring the chilling requirement of peaches is characterized in
that collect branches of current year every 4 - 5 days after the peach leaves fall, wherein,
the branch length is 20 - 30 cm and there are more than 20 flower buds and leaf buds on
each branch. Then insert these branches into water for 2 - 3 cm indoors. Cut the lower
parts of the peach branches every 3 days to expose fresh colour, and change water every 3
days. The indoor conditions are as follows: day with temperature 23 25 °C for 14
hours, night with temperature 15 ~ 17 °C for 10 hours, humidity 60 70% and light
25001x. When 50% of leaf buds are exposed and 50% of flower buds are blooming, it
means that flower buds and leaf buds meet their own chilling requirement. According to
this method, after 15 days, the complete statistics of the blossom rate and germination
rate can be used to determine its chilling requirement.
The method has following beneficial technical effects. Adopting the method in this
invention, the blossom rate and germination rate can be counted in only 15 days, and after
days, the complete statistics of the blossom rate and germination rate can be used to
determine its chilling requirement, which saves 7 - 13 days compared with the traditional method (21 - 28 days). In addition, there are various requirements in traditional methods, which are difficult to be controlled. While, the method in this invention has simple determination conditions and operation.
In the following, the technical scheme in the embodiments of the present invention will
be described clearly and completely in combination with the embodiments of the present
invention. Obviously, the described embodiments are only part of the embodiments of the
present invention, not all of them. Based on the embodiments of the present invention, all
other embodiments obtained by ordinary technicians in the field without creative labor
should belong to the protection scope of the present invention.
Embodiment 1
A method for quickly measuring the chilling requirement of peaches is to collect
branches of current year every 4 days after the peach leaves fall, wherein, the branch
length is 20 cm and there are more than 20 flower buds and leaf buds on each branch.
Then insert these branches into water for 2 cm indoors. Cut the lower parts of the peach
branches every 3 days to expose fresh colour, and change water every 3 days. The indoor
conditions are as follows: day with temperature 23 °C for 14 hours, night with
temperature 15 °C for 10 hours, humidity 60 % and light 25001x. When 50% of leaf buds
are exposed and 50% of flower buds are blooming, it means that flower buds and leaf
buds meet their own chilling requirement. According to this method, after 15 days, the
complete statistics of the blossom rate and germination rate can be used to determine its
chilling requirement.
Embodiment 2
A method for quickly measuring the chilling requirement of peaches is to collect
branches of current year every 5 days after the peach leaves fall, wherein, the branch
length is 25 cm and there are 22 flower buds and leaf buds on each branch. Then insert
these branches into water for 2.5 cm indoors. Cut the lower parts of the peach branches
every 3 days to expose fresh colour, and change water every 3 days. The indoor
conditions are as follows: day with temperature 24 °C for 14 hours, night with
temperature 16 °C for 10 hours, humidity 65 % and light 25001x. When 50% of leaf buds
are exposed and 50% of flower buds are blooming, it means that flower buds and leaf
buds meet their own chilling requirement. According to this method, after 15 days, the
complete statistics of the blossom rate and germination rate can be used to determine its
chilling requirement.
Embodiment 3
A method for quickly measuring the chilling requirement of peaches is to collect
branches of current year every 4 days after the peach leaves fall, wherein, the branch
length is 30 cm and there are 23 flower buds and leaf buds on each branch. Then insert
these branches into water for 3 cm indoors. Cut the lower parts of the peach branches
every 3 days to expose fresh colour, and change water every 3 days. The indoor
conditions are as follows: day with temperature 25 °C for 14 hours, night with
temperature 17 °C for 10 hours, humidity 70 % and light 25001x. When 50% of leaf buds
are exposed and 50% of flower buds are blooming, it means that flower buds and leaf
buds meet their own chilling requirement. According to this method, after 15 days, the complete statistics of the blossom rate and germination rate can be used to determine its chilling requirement.
The foregoing is only a preferred embodiment of the present invention and is not
intended to limit the present invention. Any modifications, equivalent substitutions,
improvements and others made within the spirit and principles of the present invention
shall be included in the protection scope of the present invention.
