Technical field
The present invention relates to tree whitening agent field is and in particular to a kind of trunk whitewashing compositionss, the tree containing said composition Dry white-out agent and application.
Background technology
In urban landscaping, evergreen species can be scene dull autumn and winter season, increases color and life, but with Southern area is different, and after evergreen species are transplanted to the north, can survive is less, and its reason mainly has following three points:First It is to produce freeze injury, the northern area of China easily occurs extreme low temperature, the cooling of extreme day and extreme continuous cooling event, if the limit is low The warm weather persistent period is long, the phenomenon arise that a lot of evergreen species frost bittens, freezing to death;Second is the wound that day burns to trunk Evil, because the sunlight on daytime of north of china in winter irradiates strong, trunk sunny slope temperature rising, cell thawing, night temperatures decline, again weight Newly freeze, one freezes a change repeatedly, will result in the death of trees dermal tissue, produce " day burns " phenomenon;3rd is stripping to branch The injury causing, early spring ground temperature gos up slowly, and temperature luffing is big, and rainfall is few, northern area much wind dry weather, early spring tree body Upper part runs into hot weather and is easy for breaking dormancy, but soil layer is still in sharp freezing state, root water uptake ability, root system The moisture absorbing can not meet the rising needs of plant, lead to plant Water content of branch degradation, lead to plant stripping phenomenon Generation.So, evergreen species are in the north because occurring freeze injury, day to burn and stripping phenomenon leads to that large area trunk is withered to die Phenomenon is very universal.
At present, trunk survives the winter protection major measure for being wound around straw rope and trunk whitewashing, but is wound around straw rope and occurs in that many Drawback, the straw rope being such as wound around provides, for insect, environment of surviving the winter, and coming year insect pest increases, and straw rope is wound around artificial and material cost height. So mostly carrying out protection of surviving the winter at present by the way of trunk whitewashing, trunk whitewashing is it is therefore an objective to prevention and elimination of disease and pests and delay are set Wooden rudiment, it is to avoid harm of burning day, in the continental climate area that sunshine, temperature change are violent, whitewashes and can weaken trees on the ground Partially absorb solar radiant heat, thus postponing the sprouting period of bud, whitewashing and can reflect sunlight, it is to avoid the local of branch humidity is increased, Thus can effectively prevent harm of burning day;May also function as necessarily preventing and treating trunk borer, skin ulcer disease etc.;Whitewash highly consistent woods Wood more gives people a kind of neat unique aesthetic feeling, and tree whitening is beautified the environment and reduced road traffic accident.
