Background

Nowadays, some trees are often planted on urban town roads, inter-city highways, express roads, country roads, park greenbelts, district greenbelts and the like. The planting specification breast-height diameter is different from 10-50cm, when in planting, some trees are purchased and transplanted in a nursery garden, and after planting, root fixing water needs to be supported and irrigated. In addition, in coastal cities, even trees from small to large are often blown down due to typhoons. Therefore, in order to protect the trees from being influenced by wind and rain and grow upwards all the time, a protection device is designed, the simplest device is three or four wood rods which are respectively supported on the ground around the trees, and the upper ends of the three wood rods are tied together at the middle-lower part of the trunk of the trees. The more complicated structure is formed by metal support rods. For example, 762 Chinese patent documents were retrieved according to the keyword "ti, ab, clm: (tree or plant and wind resistant and support and device or structure) ANDic1, ic2 (A01)". Among them, there are 43 pieces of patent documents with a hinge structure having an adjusting function. Some of these 43 patents have contributed to a more practical adjustable fixation structure to protect the tree from standing upright. For example, CN201921795147.9 discloses a supporting device for preventing wind of green seedlings, which is a way of splicing four circular arc structures. For another example, CN201710687243.0 discloses an easily adjustable stable supporting device for garden trees, in which the outer ring is completely fixed by two semi-circular arcs, and the inner ring is an arc-shaped clamping plate structure adjusted by screw threads. The structures cannot be adjusted again after being assembled and fixed, the application range of each part is small, when the diameters are different greatly, main parts cannot be used universally, and products with various specifications need to be machined more. For the tree management unit, the cost is increased.

Therefore, there is a need to develop a tree guard that is more versatile in its components and has a greater range of adjustment. And it is necessary to increase the protection time from smaller trunks up to larger trunks.

According to the specific embodiment I of the method for protecting the garden landscape trees, the protection device of the embodiment five or the embodiment six is adopted, the communication module is in communication connection with the tree management background, and the initial value of the pressure sensor is recorded when the device is installed initially; the controller obtains a wind speed signal from the tree management background through the communication module, when the wind speed is lower than a set value (such as 2m/s), the data of the pressure sensors are detected, when the average change value of the adjacent pressure sensors exceeds a preset value, the controller sends an alarm signal to the tree management background through the communication module, and a fertilizer and moisture are applied manually or by a fertilizer applicator from a fertilizing pipe of the metal fixing pile in the opposite direction, so that the root growth in the opposite position is promoted, and further powerful fixing force is generated to adjust the growth direction of the tree. When the detection signal of the humidity sensor is lower than the preset value, the controller sends a water shortage signal to the tree management background through the communication module.

In more specific embodiments, the wind speed may be further collected, and when the wind speed is greater than a specific value (for example, 20m/s), the data of the pressure sensor on the stressed side is detected, when the pressure value of the pressure sensor is lower than a set low value, a robust signal generated by the tree is output, and when the pressure value of the pressure sensor is higher than a set high value, a non-robust signal generated by the tree is output. When a tree generates a robust signal output, the support ring in the protective device may be removed or the clamping force on the trunk reduced by the manager.

According to the second specific embodiment of the garden landscape tree protection method, the protection device of the fifth embodiment or the sixth embodiment is adopted, the communication module is in communication connection with the tree management background, the data of the tree diameter sensor is periodically sent to the tree management background, and when the data exceed a preset value, a signal for adjusting the support ring is output; periodically sending the data of the tree increase amount calculated by the change amount of the effective resistance value of the vertical resistance strip to a tree management background, and outputting a signal for adjusting the support ring when the tree increase amount exceeds a preset value; the detection period of the controller receiving the variation of the effective resistance values of the tree diameter sensor and the vertical resistive strip is in units of days.

Therefore, in order to enable the slip ring or the trunk attachment ring to generate uniform pressure on the trunk, when the device is installed, a gap (such as 15mm-50 mm) between the slip ring (or the trunk attachment ring) and the trunk is increased, protective films (such as electrostatic films) are attached to the inner walls of the gap between the slip ring (or the trunk attachment ring) and the trunk, the lower end of the protective films is blocked by a baffle, lime slurry or gypsum slurry is poured into the gap, and after the lime slurry or the gypsum slurry is solidified and formed, the baffle and the protective films are detached and then installed again. The structure can ensure that the tree is stressed uniformly and can also have the sterilization and disinfection effects on the surface of the tree.

In other embodiments, three support rods may be used, and when the diameter of the trunk exceeds a certain value, the number of the support rods may be increased to five or six to provide the support capability without changing the model of the support ring. The controller can be realized by a single chip microcomputer and peripheral circuits thereof, and can also be realized by a small-sized PLC controller.

And furthermore, a long-strip-shaped hole is adopted at the joint of the connecting block and the supporting ring block, so that the adjustment is convenient and the operation is simple. The connecting block adopts a two-section type hinged structure, so that the adjusting range is further increased. Further, a metal fixing pile with a fertilizing pipe is adopted, so that the lower end of the supporting rod can be fixed, and multi-level (different depths) fertilization can be performed on trees. Furthermore, a pressure sensor is arranged on the inner side of the support ring block, so that whether the trunk inclines or not can be detected.
