Forestry nursery stock planting wind shielding and freeze protecting device

Abstract

The invention discloses a forestry nursery stock planting wind shielding and freeze protecting device which comprises a soil layer and a nursery stock main trunk. The nursery stock main trunk is planted on the soil layer, first side plates are arranged on the left side and the right side of the upper end of the soil layer, a second side plate is arranged between every two corresponding ends of thetwo first side plates by means of bolted connection, and the specifications of the second side plates are identical to each other. The forestry nursery stock planting wind shielding and freeze protecting device has the advantages that the forestry nursery stock planting wind shielding and freeze protecting device is reasonable in design, a lime layer is brushed on the outer wall of the nursery stock main trunk, accordingly, freezing injury of trees mainly can be prevented and treated, and the trees can advantageously safely live through the winter and can be protected against being injured bythe external nature; the forestry nursery stock planting wind shielding and freeze protecting device is provided with expanded polyethylene, and accordingly good heat-insulation and cold-resistant effects can be realized for the nursery stock main trunk; the forestry nursery stock planting wind shielding and freeze protecting device is provided with a plastic film layer and a straw mat, and accordingly the trees are high in waterproof ability and cold resistance; the expanded polyethylene, the plastic film layer and the straw mat can be firmly fixed to the outer wall of the nursery stock maintrunk by the aid of rope belts.

Description

technical field [0001] The invention relates to the technical field of planting seedlings, in particular to a wind-shielding and anti-freezing device for planting forestry seedlings. Background technique [0002] my country has a vast territory, very complicated natural conditions, a wide variety of trees, and a wide distribution area. In addition, the climate has been very abnormal in recent years. Various forest tree seedlings are often subjected to different degrees of frost damage and wind attack when they are planted. [0003] However, in the existing antifreeze measures, it is generally adopted to wrap plastic film on the outer wall of the main pole of the nursery stock and wrap a black grid cover on the outer wall of the plastic film. The structure is relatively simple, but the setting effect is not ideal, and the fixing effect is not good. It is easy to fall due to the wind for a long time. In addition, the roots of the seedlings will bend under the wind attack, whic...

[0003] However, in the existing antifreeze measures, it is generally adopted to wrap plastic film on the outer wall of the main pole of the nursery stock and wrap a black grid cover on the outer wall of the plastic film. The structure is relatively simple, but the setting effect is not ideal, and the fixing effect is not good. It is easy to fall due to the wind for a long time. In addition, the roots of the seedlings will bend under the wind attack, which reduces the survival rate. device to solve the above problems
