The cover plate 2 is formed by combining two identical plate bodies 21 which can be correspondingly buckled in the lip edges 111 of the upper openings of the two seat bodies 11 one by one, and the center of the cover plate 2 is provided with a circular avoidance hole 22 which is formed by encircling two semi-arc surfaces with the same radius; each plate body 21 of the cover plate 2 is provided with a vent pipe mounting hole 211 for mounting the vent pipe assembly 3. The breather pipe assembly 3 include breather pipe 31 and pipe cap 32, breather pipe 31 be the hollow pipe that the diameter is not less than 100mm, be equipped with a plurality of diameter vent 311 that the diameter is not less than 10mm on its lateral wall, be equipped with the external screw thread on its upper end outer wall, pipe cap 32 be equipped with the internal thread that matches with the external screw thread of breather pipe 31, pipe cap 32 spiro union is used for preventing the foreign matter from getting into breather pipe 31 in breather pipe 31 upper end. The replacement core 4 is formed by encircling two same replacement core blocks 41 with concave tables 411 at the bottoms, and a circular tree hole 42 formed by encircling two semi-arc surfaces with the same radius is formed in the center of the replacement core and is used for a trunk of a street tree to pass through; the core 4 is provided with a plurality of sets of substitutes with different tree hole 42 apertures, and the substitutes can be adapted and replaced according to different tree species and tree trunk diameters of trees in different growth periods. The replacement core 4 is arranged in the surrounding seat hole 112 of the root control base 1, and the concave table 411 of the replacement core is attached to the boss 114 of the surrounding seat hole 112; the cover plate 2 is buckled on the root control base 1; the breather pipe component 3 is fixedly connected on the cover plate 2 and can enable the cavity of the root control base 1 which is buckled with the cover plate 2 to freely ventilate.

The use method of the street tree root control device is as follows:

the root of the street tree is buried in the dug tree hole, backfilling is stopped until the height from the ground is consistent with that of the root control base 1, and the root of the tree needs to be buried in the soil completely.

The two seat bodies 11 are placed into the tree hole which is not filled with soil from two sides of the trunk and are laid flat, so that the upper surfaces of the seat bodies 11 are flush with the ground. The two seat bodies 11 are spliced to enable the adjacent side walls to be completely attached, and then the locking pieces 13 are used for locking the side walls of the two seat bodies 11.

Then the two plate bodies 21 of the cover plate 2 provided with the vent pipe assembly 3 are respectively buckled in the upper mouth lips 111 of the two seat bodies 11.

And selecting the core replacing 4 with the aperture of the tree hole 42 matched with the trunk diameter of the tree in all the streets, putting two core replacing blocks 41 of the core replacing 4 into the seat surrounding hole 112 of the root control base 1 from two sides of the trunk, and attaching the concave table 411 of the core replacing block to the boss 114 of the seat surrounding hole 112.

And then pouring concrete into the gaps around the root control base 1 to fixedly connect the root control base 1 with the ground.

During the maintenance period after the street trees are planted, the pipe cap 32 of the vent pipe assembly 3 is unscrewed each time, water and nutrient solution are injected from the upper opening of the vent pipe 31 to the tray body of the root control base 1 for storage, and the tree roots are automatically replenished with water and fertilized by slowly releasing and permeating the water and the nutrient solution through the tiny root control holes 113 at the bottom of the root control base 1.

After the maintenance period, no longer store water and nutrient solution in the disk body of accuse root base 1, the air gets into the lock through the air vent 311 of the breather pipe 31 side of breather pipe subassembly 3 and has the intracavity of the accuse root base 1 of apron 2, and discharge below 1 of accuse root base through accuse root hole 113, the trees root must contact the air and covered unable growth and automatic withering by accuse root base 1, other root must then continue to grow to the soil depths of keeping away from accuse root base 1, thereby the growth direction of control root must, make the root no longer grow to ground.

If the trunk is long and thick, the replacement core 4 can be taken out of the surrounding seat hole 112, and a new replacement core 4 matched with the trunk diameter is replaced.

The utility model discloses with the growth direction that has the accuse root base control root palpus of accuse root hole and at trees initial stage automatic infiltration moisturizing fertilization of planting, can solve the broken ground that urban street tree root brought to ground growth and make the pavement uneven or damaged, influence the city hold and pedestrian's safety and trees initial stage automatic water replenishing fertilization inconvenient problem of planting.

The above is only a specific embodiment of the present invention, but the design concept of the present invention is not limited to this, and the present invention is to be modified immaterial by this concept, and all should belong to the act of infringing the protection scope of the present invention.
