Description
Technical Field
The invention belongs to the field of garden engineering, and particularly relates to a standard precontrol device for planting street trees and a construction method.
Background
In the traditional planting process of the street trees, the planting elevation of the street trees is difficult to pre-control, equipment for controlling the planting depth is lacked in the prior art, the planting depth is usually controlled through observation of field personnel, the relative error is large, and the planting depth is too deep, so that the root is affected by oxygen deficiency, root walking is avoided, buds are stuffy, the growth vigor is weak and the like; when planting is shallow, the root pressure is insufficient, and water backflow is caused. Therefore, the seedling planting depth control has profound significance for ensuring the survival rate of the seedlings and the landscape effect of the seedlings.
In the process of erecting the support of the street trees, due to the lack of the elevation precontrol device, the elevation precontrol effect of the support is not ideal, the unified elevation standard cannot be reached, and the erecting effect of the support is influenced. Meanwhile, the part of the support, which is in contact with the tree, is supported, the generated pressure is too large, and the long-time contact can influence the normal development and growth of the nursery stock and the ornamental value of the nursery stock.
At present, the height of whitewash of street trees is not uniform, the whitewash is generally influenced by the operation of field construction personnel, the uniform height is difficult to realize even if the requirements are made on the field personnel, and meanwhile, the whitewash upper ends are not neat enough and are uneven, so that the landscape effect of nursery stocks is influenced.
The pruning of the street trees can be an important part in the road greening construction process, and the excellent pruning process can improve the whole road greening artistry and landscape effect, so that the management and control of the elevation of the branch points of the street trees are very important. In the traditional construction process, a uniform standard is provided for branch point pruning generally, but in the implementation process, the elevation is controlled by a conventional and effective means, so that the heights of the whole branch points are different, and the overall viewing experience is reduced.
When the nursery stock is hung in the bag for transfusion, the nursery stock is often hung on the branch or the main trunk is provided with nails for hanging, so that the ornamental effect of the nursery stock is influenced, and meanwhile, certain potential safety hazards are caused. In addition, the height of the hanging nutrient solution can affect the flow rate of the nutrient solution and the seedling absorption condition.

Step six: whitewashing
If the procedure of whitewashing is needed, a steel ruler 1 is wound at the whitewashing highest point of the foremost nursery stock, the lower edge of the steel ruler 1 is located at the whitewashing highest point, a laser range finder 5 and an infrared level meter 6 are installed on the steel ruler 1, the infrared level meter 6 is opened to level the steel ruler 1, the laser range finder 5 is opened to enable laser to be applied to the nursery stock adjacent to the back, the steel ruler 1 is wound and fixed on the nursery stock on the back according to the laser position, the laser range finder 5 and the infrared level meter 6 are installed on the upper surface, the laser emitted by the front laser range finder 5 and the laser emitted by the rear laser range finder 5 are on the same horizontal line, and then the laser range finder 5 and the infrared level meter 6 on the nursery stock steel ruler 1 on the foremost are taken down.
By analogy, according to the steps, the fixing positions of the steel ruler 1 are determined at the white coating highest point of the rear nursery stock in sequence by taking the nursery stock in the front as a reference, the steel ruler 1 is wound at the white coating highest point of all the nursery stocks, the laser range finder 5 and the infrared level meter 6 are all taken down, and only the steel ruler 1 is kept at the white coating highest point.
And finally, whitening the nursery stock according to the steel ruler 1 at the highest point of the whitening, whitening below the steel ruler 1, and taking down the steel ruler 1 after whitening, so that the upper end of the whitening is neat, all nursery stocks are whitened at the same height, and the ornamental effect is improved.
Step seven: branch pruning and infusion in nursery stock maintenance period
In the nursery stock maintenance period, fixing a steel ruler 1 at the branch point of the foremost nursery stock, installing a laser range finder 5 and an infrared level meter 6 on the steel ruler 1, opening the infrared level meter 6 to level the steel ruler 1, opening the laser range finder 5 to enable laser to be applied to the nursery stock adjacent to the back, fixing the steel ruler 1 on the nursery stock at the back according to the laser position, installing the laser range finder 5 and the infrared level meter 6 on the upper surface, and then taking down the laser range finder 5 and the infrared level meter 6 on the nursery stock steel ruler 1 at the foremost; by analogy, the front nursery stocks are taken as reference, the steel ruler 1 is fixed at the branch point of the rear nursery stocks in sequence, finally, only the steel ruler 1 at the branch point is reserved, and finally, the nursery stocks are trimmed according to the steel ruler 1 at the branch point of the nursery stocks. All branch points of the nursery stock pruning are at the same height, and the requirement of uniform control on the pruning height of the branch points is met.
If the seedlings need to be infused, a hanging ring 4 is arranged at the hole 3 of the steel ruler 1 at the branch point of the seedlings, the elastic expansion part 7 is plugged from the hole 3 and connected with the hanging ring 4, and nutrient solution is hung on the hanging ring 4 for infusion, so that the hanging elevation of the nutrient solution is uniformly pre-controlled.
And after the maintenance is finished, all the steel rulers 1 are taken down.

step six: if the white coating process is needed, winding a steel ruler (1) at the white coating highest point of the foremost nursery stock, installing a laser range finder (5) and an infrared level gauge (6) on the steel ruler (1), opening the infrared level gauge (6) to level the steel ruler (1), opening the laser range finder (5) to enable laser to be applied to the nursery stock adjacent to the back, winding the steel ruler (1) on the nursery stock on the back according to the laser position, installing the laser range finder (5) and the infrared level gauge (6) on the upper surface, and then taking down the laser range finder (5) and the infrared level gauge (6) on the steel ruler (1) of the foremost nursery stock; by analogy, sequentially winding a steel ruler (1) at the white-coated highest point of the nursery stock at the back by taking the nursery stock at the front as a reference, finally white-coating the nursery stock according to the steel ruler (1) at the white-coated highest point, white-coating the nursery stock below the steel ruler (1), and taking down the steel ruler (1) after white-coating;
step seven: during the nursery stock maintenance period, winding a steel ruler (1) at the branch point of the foremost nursery stock, installing a laser range finder (5) and an infrared level meter (6) on the steel ruler (1), opening the infrared level meter (6) to level the steel ruler (1), opening the laser range finder (5) to enable laser to be applied to the nursery stock adjacent to the back, winding the steel ruler (1) on the back according to the laser position of the nursery stock, installing the laser range finder (5) and the infrared level meter (6) on the back, and taking down the laser range finder (5) and the infrared level meter (6) on the foremost nursery stock steel ruler (1); by analogy, the front nursery stocks are taken as reference, steel rulers (1) are wound at the branch points of the rear nursery stocks in sequence, and finally, the nursery stocks are trimmed according to the steel rulers (1) at the branch points of the nursery stocks; if the seedlings need to be infused, a hanging ring (4) is arranged at the hole (3) of the steel ruler (1) at the branch point of the seedlings, and nutrient solution is hung on the hanging ring (4) for infusion; and after the maintenance is finished, all the steel rulers (1) are taken down.
