PURPOSE: A tree protection apparatus is provided to solve the problems of the inconvenient installation and highly required man power. CONSTITUTION: A supply sheet is equipped to surround the exposed part of tree on the ground, and discharges agricultural chemicals supplied from the outside to the exposed part of tree on the ground. Embrocation(210) is coated on the top end and bottom end of the supply sheet, and hermetically seals the space between the exposed part of the tree on the ground and the supply sheet. An agricultural chemical supply unit(10) equipped outside of the supply sheet contains agricultural chemicals and supply the agricultural chemicals to the supply sheet. The embrocation is coated on at least one more part inside of the supply sheet. A first sheet covers the outside of the supply sheet in order to prevent the supply sheet from exposing to outside. The first sheet is made of transparent materials. A second sheet(130) is formed with patterns having visual impression, and covers the outside of the first sheet. At least one of the supply sheet, first sheet or second sheet has elasticity. Auxiliary supply materials(300,310) are formed between the exposed part of the tree on the ground and the supply sheet. A protective cover with a predetermined area is settled on the bottom surface, and has a through-hole where trunk penetrates through. The protective cover covers the exposed part of the root on the ground. Pigment is mixed with the agricultural chemicals. An adhesive material for capture of pests is coated between the exposed part of the tree on the ground and the supply sheet. |
