Description
Technical field
The protection technology field the present invention relates to trees survive the winter, and in particular to North Jiangsu Area Cortex cinnamomi camphorae trunk winter cold-proof heat insulation
Method.
Technical background
Cortex cinnamomi camphorae is that Subtropical Evergreen Broad-leaf Forest represents seeds, likes the weather conditions of warm and moist, suitable growth region
Between 10-30 DEG C of north latitude, the main place of production is distributed on the south the Changjiang river and southwest, and the mean temperature of suitable growth is 16-17
℃。
With the fast-developing and global warming of urban construction, because the big shade of Radix Cinnamomi porrecti tree crown is dense, tree performance is grand, vein is told
Perfume (or spice), winter evergreen advantage gradually introduces a fine variety in a large number plant by North of Yangtze River area.But the trans-regional trees for drawing plant, because of existence
Environmental condition is changed, and need to be taken and targetedly be protected, and Cortex cinnamomi camphorae meets extremely cold low temperature can be subjected to destructive freeze injury, such as
2016.1.22-24 day, North Jiangsu Area temperature is rare to drop to -9～-14 DEG C, causes a large amount of Cortex cinnamomi camphorae to be subjected to serious cold damage, has
Disleave, what is had is withered, and its frigolabile feature is determined before annual winter approached, will take cold-proof heat insulation to Radix Cinnamomi porrecti trunk
Measure.
Since Cortex cinnamomi camphorae draws plant from before and after 2000, the cold-proof heat insulation measure of a used employing is：When before winter approached, to perfume (or spice)
Straw rope or non-woven fabrics more than Lignum cinnamomi camphorae trunk portion or tree root are wound in 1.5 meters of altitude ranges, then in the straw rope or nonwoven for wrapping
Cloth is additional to wrap up in black plastic film.There is following drawback in the composite thermal insulation way：
（1）Rainwater causes artificial secondary freeze injury
North Jiangsu Area Precipitation in Winter still with rain based on, snow supplemented by.When rainy, rainwater can be from the straw rope of Cortex cinnamomi camphorae parcel or nothing
The upper port of spinning the cloth wet straw rope of macerate or non-woven fabrics under trunk crackle groove part, because the moisture in black plastic film is difficult
Distribute, the straw rope or non-woven fabrics chance for causing humidity freezes ice, so as to cause artificial secondary freeze injury to Cortex cinnamomi camphorae.
（2）Vapor causes artificial secondary freeze injury
When winter is sunny, substantial amounts of vapor is produced in black plastic film, be liquefied as after water droplet by straw rope or non-woven fabrics
Absorb, day by day, straw rope or non-woven fabrics humidity gradually increase, causing the straw rope or non-woven fabrics of moisture content can also meet and freeze ice,
Also artificial secondary freeze injury is caused to Cortex cinnamomi camphorae.
（3）Straw rope makes moist easily to black and rots.
Straw rope in black plastic film makes moist, and moisture fails to distribute in time, meets sunlight and fills
When sufficient, it is easy to black and rot, waste material.
The content of the invention
The present invention is a kind of North Jiangsu Area Cortex cinnamomi camphorae trunk winter cold-proof heat insulation method of offer that solves the above problems, it is to avoid
Artificial secondary freeze injury, Cortex cinnamomi camphorae survival rate of enduring cold is high, significantly saves manually and material cost.
The present invention is achieved through the following technical solutions：
North Jiangsu Area Cortex cinnamomi camphorae trunk winter cold-proof heat insulation method, when temperature is down to and closes on 5 DEG C before annual winter approached, to Radix Cinnamomi porrecti
Tree root base portion is often enclosed between straw rope and does not stay gap to the closely knit winding straw rope of one-level branching-point, or swathes non-woven fabrics, often encloses non-woven fabrics
Overlap and be no less than 2cm, Second Year the beginning of April removes the straw rope or non-woven fabrics for swathing the Ching Ming Festival around.
The straw rope of conventional process winding in the past leaves 0.5-1cm gaps between often enclosing, and non-woven fabrics lap is less than 2cm, no
It is poor plus plastic sheeting moistening effect, and rainwater soaks seriously, plus wrap up in plastic sheeting and seem and enhance heat insulation effect, but together
When again produce secondary freeze injury.
This method without secondary freeze injury, that is, is met the rainy day to Cortex cinnamomi camphorae, and the straw rope being soaked with rain or nonwoven can in time by wind
It is dry, or dry day；Also anhydrous steam soaks, so as to cause artificial secondary freeze injury, insulation, cold-resistant effect to Cortex cinnamomi camphorae
Good, trees survival rate is high.
Temperature is down to 5 DEG C or so（About annual the beginning of November）, when Cortex cinnamomi camphorae enters resting state, Cortex cinnamomi camphorae is taken and is arranged
Apply, Second Year the beginning of April, Cortex cinnamomi camphorae is removed when will enter trophophase, the conventional conventional process time is upper random very big, has
What is had in advance delays, and some unit dismounting time is 5, June, and the time of dismounting has damaged too late, not only bark, and is unfavorable for
The growth of Cortex cinnamomi camphorae.
Further improvement project of the invention is that straw rope raw material is made from Φ 1.4-1.6cm rice grass, or non-woven fabrics are selected
Three layers of plant binder, outer layer is non-woven fabrics, and intermediate layer is thin film with holes.
Straw rope and non-woven fabrics that in the past conventional practice was selected, are not quite similar, and the meticulous heat insulation effect of straw rope is poor, excessively thick then gap
Greatly, now from the rice grass of even thickness, closely, moisturizing good permeability winds gapless to quality；In the past non-woven fabrics or monolayer or
Double-layer heat insulation effect is also poor, three for now selecting layer plant binder, and insulation is again ventilative.
Advantage of the present invention compared with conventional art scheme：
1. without secondary artificial freeze injury, insulation, cold-resistant effect are good, and trees survival rate is high.
2. material-saving：Straw rope or non-woven fabrics the beginning of April withdraw in time, it is reusable for many years；Plastics need not be bought thin
Film, reduces material cost；
3. save artificial：Need not wrap up in Cortex cinnamomi camphorae again, tear black plastic film open, reduce cost of labor.
Specific embodiment
The practice of the inventive method：
By taking the Cortex cinnamomi camphorae of North Jiangsu Area Huaiyingong College campus as an example：The Jiangsu that Huaiyingong College is located at the ㎞ of North of Yangtze River 200
Province Huai'an, is the Northern Margin area of Radix Cinnamomi porrecti tree planting positioned at 43 '～34 ° of 06 ' place of north latitude 32 °, and belonging to can plant but easily receive
Freeze injury area.
2005--2006, the school introduces a fine variety 2000 plants in Mei Cheng roads school district, and campus shade tree is made in cultivation, and diameter of a cross-section of a tree trunk 1.3 meters above the ground 10cm is in the majority.
In order to carry out winter Cortex cinnamomi camphorae trunk warming measure, 2005-2007, the professional of the school greening health center is continuous
Usual cold-proof heat insulation way is taken within 3 years, i.e., winds straw rope to Cortex cinnamomi camphorae trunk before and after annual November, additional to wrap up in black plastic thin
Film, but, when Second Year removes the black plastic film on Cortex cinnamomi camphorae trunk, it is new that professional has found that last Nov winds
Straw rope has blacked, and what is had even rots, and is particularly acute especially proximate to root area, and the trunk local bark of tree is damaged
Wound, color generation blacking, triennial of here, though minimum -8 DEG C or so of temperature, Cortex cinnamomi camphorae survival rate is 90% or so.It is green
Change practice of the professional of health center through 3 years, find after further investigation, straw rope blacks and rots to be because that straw rope makes moist,
Caused by moisture fails to distribute in time, and the black plastic film for causing the seed of trouble of this reason to be exactly plus wrap up in, cause to rain what is oozed
Water, vapor are difficult to distribute, and chance freezes ice, so as to cause artificial secondary freeze injury to Cortex cinnamomi camphorae.
After pinpointing the problems, from 2008 so far, the professional of Huaiyingong College is given every year by the heat preserving method of the present invention
Cortex cinnamomi camphorae trunk wraps up in the wide plant binder of straw rope or 13cm（In recent years, the heat insulating material just having on market）Afterwards, just no longer
Plus wrap up in black plastic film, this new way both material saving, and less manpower, heat insulation effect is also fine.The perfume (or spice) of Huaiyingong College
Lignum cinnamomi camphorae has withstood the test of rare low temperature of in January, 2016 North Jiangsu Area over 24 years, and Cortex cinnamomi camphorae survival rate of enduring cold is up to
98%, and with area, the Cortex cinnamomi camphorae in other regions is relatively low by freeze injury survival rate, only 60% less than its reason is just in secondary freeze injury band
The adverse consequencess come.
