Description

Educate large-scale tree and hold together to stick together to put root flashboard device

[technical field] the utility model relates to the device that tree field cultivation type sapling is educated in a kind of gardens.

Large-scale tree transplanting is badly in need of in [background technology] existing urban afforestation, and gardens department all scratches to forest land in blocks mostly and digs transplanting, and this practice one is that cost is high; The 2nd, destroy the root system of other forest.Present China useful plastic housing in south is cultivated the minimal tree that 2-3 gives birth to, and all puts on the ground, and the promptly easy drought of the sapling of cultivating is like this avoided duty again and watered; Formation sapling hat is worked energetically and is not endured; This kind situation is to lack the deep layer element, adds that again the people expedites the emergence of formation for educating nitrogen, still can not satisfy the demand of urban afforestation.

[summary of the invention] the utility model purpose provides a kind of device that can cultivate large-scale tree in order to overcome above-mentioned deficiency.

The purpose of the utility model is achieved in that this utility model partly is made up of flashboard, little plank, Polypropylence Sheet, nylon rope etc.Flashboard is four identical cement steel prefabricated boards of size shape wide at the top and narrow at the bottom, in educating tree well with corresponding in twos being embedded in the tree well of four shoe brake plates.Every side two shoe brake plates in the both sides of correspondence, wide is leaned on mutually, and narrow is relatively, and two little planks are separately fixed at flashboard bottom, both sides.Form two equal-sized symmetric spaces like this in the middle of flashboard bottom and the little plank.Polypropylence Sheet covers in advance educates around the tree well, fixes through the flashboard and the little plank of standing.The place, space that in the middle of flashboard and little plank, forms is cut into breach covering good Polypropylence Sheet.Educate the tree well bottom to two parallel being placed on of nylon rope at last, two of nylon rope gets final product under being pressed in little plank.The wide 14cm of its flashboard the first half, the wide 7cm of the latter half, total length 70cm, thick 4-5cm.There is back bending at the long 75cm of reinforcing bar two in the flashboard, and there is the through hole of two correspondences the flashboard upper end.The high 21cm of its little plank, wide 14cm, thick 3cm, its plastic section is thick Polypropylence Sheet.Its nylon rope is that parallel being placed in of long two nylon ropes of two each 80cm educated tree well bottom interval 15cm, the utlity model has and can bring out the large-scale sapling of 5-7, and transplant conveniently, does not injure other fine-root, low cost and other advantages.

Description of drawings:

Fig. 1, for educating the large-scale tree flashboard device overall schematic of holding together to stick together,

Fig. 2, for educating the large-scale tree flashboard device end view that holds together to stick together,

Fig. 3, for educating the large-scale tree flashboard device vertical view that holds together to stick together.

[embodiment] can know that from Fig. 1～Fig. 3 this utility model is when implementing; To dig out dark 70cm earlier; Hole diameter 70cm educates large-scale tree tree well, covers the hole wall on every side with thick Polypropylence Sheet 6 earlier in each hole, then corresponding in twos being embedded on the tree well wall of four shoe brake plates 1.There is back bending at reinforcing bar 3 two in the flashboard 1, and solid plate iron wire 2 is arranged on the flashboard 1.In the both sides of correspondence, every side two shoe brake plates 1 wide position is leaned on up mutually, and narrow position is relative down, and little plank 4 is separately fixed at both sides flashboard 1 bottom.Little plank 4 forms two equal-sized symmetric spaces with flashboard 1 bottom, is cut into corresponding breach at this place, space covering good Polypropylence Sheet 6, is placed on two nylon ropes 5 at last and educates the tree well bottom, and nylon rope 5 two are pressed in little plank 4 bottoms, both sides respectively.

During use, at first will educate and fill up soil in the tree well, and sow seeds then or implant sapling; After cultivation in 5～7 years, during transplanting, earlier four shoe brake plates 1 are withdrawn from; Cut off the other root in both sides with sharp weapon then, take out little plank 4 again, last; Extract two nylon ropes 5 and take large-scale tree out of and hold together to stick together and sapling, supply to transplant and use.
