Description
Technical field
The invention belongs to the technical fields in gardens, and in particular to a kind of breeding method for improving trees winter resistance.
Background technology
Since Xinjiang is temperate continental climate, climatic characteristic is that day and night temperature is big, and arid, illumination is long, short of rain, is done
It is dry, it is cold in winter and hot in summer, belong to typical continental arid climate.Therefore, most of trees of Xinjiang region are cold-resistant, wind resistance, drought-enduring,
Such as：Diversiform-leaved poplar, sacsaoul, white poplar, American elm, the big Siberian elm leaf in Xinjiang, Chinese wax, arrow-leaved oleaster etc..Meanwhile the seeds of Xinjiang region are single, it can
Seeds for gardens, greening are few.It is therefore desirable to some other seeds are introduced from other places, such as：Ginkgo, stingless Chinese honey locust,
Fructus Gleditsiae triacanthotis, locust tree.But these rare trees and non-local autochthonal seeds, even if wrapping up in felt when overwintering, still remain and pass the winter
When the death rate it is higher the problem of.
In view of this, it is necessary to propose a kind of rare tree introduced suitable for Xinjiang region, rare tree is made to get over safely
The artificial culturing method in winter, the breeding method can improve the winter resistance of rare tree.
Invention content
The purpose of the present invention is to provide a kind of breeding method for improving trees winter resistance, which is suitable for Xinjiang
The rare tree that area is introduced can make rare tree safe overwintering, the survival rate after raising is overwintering.
To achieve these goals, used technical solution is：
A kind of breeding method for improving trees winter resistance, includes the following steps：
(1) tree well is dug on planting site, the soil ball diameter of tree is 8-10 times of the diameter of a cross-section of a tree trunk 1.3 meters above the ground, and tree well diameter is more than soil ball diameter
30-50cm；
(2) seedling is selected：Select growing way it is vigorous, without pest and disease damage, without the trees of mechanical damage, the diameter of a cross-section of a tree trunk 1.3 meters above the ground for 6-10cm；
(3) it is colonized：In early April to mid-April, after being sprinkled into the mellow soil of 20-30cm in tree well bottom, tree soil ball is put
It after entering in tree well, then will be filled up with mellow soil, consolidated, righting in tree well, tamping；
(4) water management：The same day pours the first water after field planting, and the second water is poured after 3 days, pours third water in the second water latter week, later
A water is poured every two weeks, is irrigated every time；After August part, watering cycle stretch-out 7-10 days after not rewatering after mid-September, arrives by the end of October
Winter irrigation water is poured between early November；
(5) overwinter management：Including sprinkling Plant antifreezer, wrap up in felt, spreading；
(6) next year, when outdoor temperature rises to 10-15 DEG C, felt item was recycled；Treat that outdoor temperature rises in third year
At 8-10 DEG C, felt item is recycled.
Further, in the step (1), the planting site of Fructus Gleditsiae triacanthotis cannot be selected at air port；
In the step (2), soil ball surface and tree trunk sprinkling carbendazim to the plantation trees of selection carry out disinfection；To tree
After Wound-healing agent is smeared at bar surface injury position, wrapped up in film and twine layer 2-3, it is dismountable after wound healing.
Further, in the step (2), the diameter of a cross-section of a tree trunk 1.3 meters above the ground of trees is 8cm；
In the step (3), tree well bottom is sprinkled into the mellow soil of 20-25cm.
Further, in the step (2), the trees of selection, which started to be completely cured in annual late February, digging and to store；
In the step (4), summer ploughs deeply plant pit surrounding soil 15-20cm, and soil waters to be dry.
Further, in the step (3), after padding one layer of 8-12cm gravel in tree well bottom, mellow soil is spread, then ginkgo is native
Ball is put into tree well；And in the surrounding of ginkgo kind plant hole, stay four ventholes.
Further, the thickness of the gravel is 10cm.
Further, the step (3) further includes, and after the trees field planting, pours into aqueous solution of taking root from soil ball outer, often
Tree pours the aqueous solution of taking root of 9-11L, and pours uniformly；The aqueous solution of taking root is according to the quality of root-inducing powder and the volume ratio of water
25g：9-11L is prepared.
Further, the aqueous solution of taking root is 25g according to the quality of root-inducing powder and the volume ratio of water：10L is prepared.
Further, in the step (5), overwinter management is specially：
The sprinkling Plant antifreezer：In late September, tree is uniformly sprayed to after Plant antifreezer is diluted 100-150 times
On, spraying range is to be sprayed three times, every minor tick 15-20 days not less than 4m high from root；
It is described to wrap up in felt：In mid-November, by felt spiral packaging trunk, to 1.5 meters of tree trunk branch point from root
More than, tight to wrap up, top is tied up with nylon rope；Plastic film is wrapped up in outside felt again；
The spreading：In mid-November, covering with ground sheeting will be used in the range of radius 1.5m around usage tree root.
Further, the sprinkling Plant antifreezer：Spraying range is full tree；
Locust tree is trimmed by the end of October every year, cutting back is carried out to branch.
Compared with prior art, the beneficial effects of the present invention are：
A kind of breeding method for improving trees winter resistance of the present invention, the breeding method is simple, suitable for Xinjiang
Ginkgo that area introduces, stingless Chinese honey locust, Fructus Gleditsiae triacanthotis, locust tree, can make rare tree safe overwintering, improve it is overwintering after survival rate,
Survival rate can reach more than 97%, while improve cold resistance.
Specific embodiment
In order to which the present invention is further explained, a kind of breeding method for improving trees winter resistance, reaches expected goal of the invention, with
Lower combination preferred embodiment, to the breeding method of a kind of raising trees winter resistance proposed according to the present invention, specific embodiment party
Formula, structure, feature and its effect are described in detail as after.In the following description, different " embodiment " or " embodiment " refers to
It is not necessarily the same embodiment.In addition, the special characteristic, structure or feature in one or more embodiments can be by any suitable forms
