Abstract
The present invention provides a kind of poinsettia plant buds dwarfing method, this method include the following: step 1) cycocel sprays processing: 10-15 days after poinsettia planting seedlings, start to apply and open quick-acting water solubility fertilizer N-P-K (20-10-20) -2000 times of liquid of 1500 times of liquid of root fertilizer for the first time；At long to 7-9, blade, topping stays 4-6；Fine day sunshade 5-7 days, lateral bud grow 2-3 centimetres of spray 750 times of liquid of cycocel；Every 15 days spray 500 times of liquid of cycocel；Step 2): poinsettia plant strain growth 70-80 days at 25-30 centimetres of plant height, 20-25 centimetres of hat width, carries out 15% paclobutrazol pouring root, and concentration is between 3-5PPM, and 150 milliliters every plant；3-5 days progress short-day sunshine treatments after pouring root.Method provided by the invention cultivates the high Poinsettia of the high quality standards for reaching poinsettia potted flower, ornamental value.
Description
Technical field
The invention belongs to field of plant cultivation, and in particular to a kind of poinsettia plant buds dwarfing method.
Background technique
Poinsettia is Euphorbiaceae Euphorbia evergreen shrubs, is liked deeply by people because its florescence is long, bract is big, bright-colored
Love, in Urban Landscape Flowers and Plants and to increase in red-letter day atmosphere be indispensable.Good plant type and suitable crown height ratio are high-quality
The most important evaluation criteria of poinsettia potted flower.When poinsettia has just emerged when the especially northern market of domestic market, great Jia Yi
Cause to think that plant is not only high but also big good, price is relatively also higher.It is difficult to illustrate hat width is much, how high plant type is on earth one
Magenta is suitble to which specific consumer, but numerous consumers unanimously think that poinsettia finished product should mutually be coordinated with plantation flowerpot,
And hat width height ratio rationally, thus should form a series of evaluation criteria of the high-quality potted flower of poinsettia in the world, domestic one
Pinkish red grower experienced one not only high but also greatly to the process for pursuing reasonable crown height ratio from plant type is pursued.Therefore, to one product of potting
Red progress plant shape regulation, improves its ornamental quality and has great significance.Using plant growth regulator adjust poinsettia plant shape,
In terms of improving its ornamental value, mostly it is to be handled using single plant growth regulator, fails to stably obtain reasonable crown height ratio
Poinsettia plant plant type.
Summary of the invention
In order to solve problem above, the present invention provides a kind of poinsettia plant buds dwarfing method, this method include the following:
Step 1) cycocel sprays processing: 10-15 days after poinsettia planting seedlings, starting to apply and opens root fertilizer readily available water for the first time
Dissolubility fertilizer -2000 times of liquid of (N-P-K=20-10-20) 1500 times of liquid；At long to 7-9, blade, topping stays 4-6；Fine day sunshade
5-7 days, lateral bud grew 2-3 centimetres of spray 750 times of liquid of cycocel；Every 15 days spray 500 times of liquid of cycocel；
At step 2) poinsettia plant strain growth 70-80 days, 25-30 centimetres of plant height, 20-25 centimetres of hat width, carry out
15% paclobutrazol pouring root, concentration is between 3-5PPM, and 150 milliliters every plant；3-5 days progress short-day sunshine treatments after pouring root.
Preferably, the poinsettia plant species be gold medal, red velvet, velvet or Jin Wang, short-day sunshine treatment 20 days
Left and right bract annesl, bract reddens completely within 45 days or so, reaches listing requirement；The poinsettia plant species are prestige or Christmas
Star, reach listing requirement within short-day sunshine treatment 50-60 days.
Compared with prior art, the invention has the following advantages:
Poinsettia plant buds dwarfing side provided by the invention includes the selection in 1) plant growth stage；2) medicament and concentration
Selection；3) selection of dosage and number；(4) new plant flower forcing processing and etc.；2 plant growth regulators differences are matched
Specific concentration and influence to Poinsettia growth and development and ornamental character is applied in different stages of growth, it is suitable to filter out
Paclobutrazol and cycocel matched proportion density and administration time, wherein cycocel is used for poinsettia seedling stage, and paclobutrazol is for poinsettia bud
Before piece annesl, and using foliage spray and 2 kinds of modes of pouring root, control method according to the invention, which can be cultivated, reaches poinsettia
The high Poinsettia of the ornamental value of potted flower high quality standards.
Specific embodiment
Embodiment 1
One, cycocel sprays processing (buds dwarfing)
10-15 days after poinsettia planting seedlings, starts to apply and open the quick-acting water solubility fertilizer N-P-K (20-10-20) of root fertilizer for the first time
- 2000 times of liquid of 1500 times of liquid.At long to 7-9, blade, topping stays 4-6；Fine day sunshade 5-7 days, lateral bud grow 2-3 centimetres of spray
750 times of liquid of cycocel；Every 15 days spray 500 times of liquid of cycocel, generally sprayed before poinsettia pouring root 3-4 times short strong
Element.
Two, plant sizing (paclobutrazol root irrigation)
Poinsettia plant strain growth 70-80 days at 25-30 centimetres of plant height, 20-25 centimetres of hat width, carries out 15% multiple-effect
Azoles pouring root, general concentration is between 3-5PPM, and 150 milliliters every plant, the increase and decrease of concentration is suitably carried out according to plant growing way.After pouring root
It can be carried out within 3-5 days shading treatment (short-day sunshine treatment).20 days bracts of the kinds such as gold medal, red velvet, velvet, Jin Wang turn
Color, bract reddens completely within 45 days, reaches listing requirement；Prestige, the magnitude kind on Christmas need to can be only achieved for 50-60 days listing and want
It asks.Table 1 lists the quality standard of poinsettia potted flower (by Zhejiang, Administration of Quality and Technology Supervision of Shanxi Province is issued).
Table 1
Using poinsettia plant buds dwarfing method provided by the invention, obtained poinsettia potted flower can reach 1 grade or 2
Grade standard has very high ornamental value.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement can also be made, these improvements and modifications should also regard
For protection scope of the present invention.
