Embodiment 1

[0015] Embodiment 1: this poplar sapling trunk protection method is carried out as follows: the first step, prepare PE pipe 1, the thickness of PE pipe 1 is 2mm to 3mm, and diameter is 5cm to 6cm, and length is 40cm to 60cm, PE The unilateral axial direction of pipe 1 is broken open; Second step, after afforestation, the branches and branches on the poplar sapling trunk 2 between the ground and 60cm from the ground are trimmed, and the poplar sapling trunk 2 surface after pruning smooth; the third step is to wrap the PE pipe 1 prepared in the first step on the trunk 2 of the pruned poplar saplings, and after the wrapping is completed, carry out normal forest management; the fourth step is to wrap it with the PE pipe 1 After the DBH of the last poplar tree 3 grows to 5cm to 6cm, the PE pipe 1 is recovered. The recovered PE pipe 1 is reused to save expenses and reduce costs.

[0016] According to actual needs, the above-mentioned poplar sapling trunk protection method can be fu...

Embodiment 2

[0017] Embodiment 2: the difference with embodiment 1 is that after the third step PE pipe 1 is wrapped, the 5cm to 10cm of the PE pipe 1 bottom is buried in the soil 4, and the poplar sapling trunk 2 above the soil surface of the soil 4 The wrapping height of the upper PE pipe 1 is 35 cm to 50 cm, and then normal forest management is carried out. If the wrapping height is too low, Tarim rabbits are easy to eat the upper bark, and the control effect is poor. If the wrapping height is too high, materials are wasted and costs are increased.

Embodiment 3

[0018] Embodiment 3: As the preference of the foregoing embodiment, the wrapping height of the PE pipe 1 on the trunk 2 of poplar saplings above the soil surface 4 is 45 cm.

Abstract

The invention relates to a method for protecting trunks of poplar saplings, which belongs to the technical field of protection of wood saplings. The method comprises the following steps of: I, preparing PE (Polyethylene) pipes, wherein the PE pipes are 2-3 millimeters in thickness, 5-6 centimeters in diameter and 45-55 centimeters in length, and single sides of the PE pipes are broken along the axial direction; and II, afforesting, trimming trunks and branch piles on poplar saplings on the ground and below 60 centimeters away from the ground, wherein the trunk surfaces of the trimmed poplar saplings are smooth. The method has high prevention and control efficiency and is low in cost, and 30 percent of cost is saved in comparison to the conventional prevention and control measure; good prevention and control effects are achieved, materials can be used circularly, and the gnawing prevention rate can be up to 100 percent in prevention and control processes; and moreover, the occurrence of pests and diseases is reduced, the cost on coating of a lime sulfur mixture onto trunks every year under the conventional prevention and control conditions for preventing and controlling pests and diseases can be lowered, and the prevention and control cost is saved.

Description

technical field [0001] The invention relates to the technical field of trunk protection of forest saplings, and relates to a method for protecting the trunks of poplar saplings. Background technique [0002] Poplar is the main tree species cultivated in the northern plains, accounting for about 70% of the planted tree species. The poplar artificial shelterbelt system plays an irreplaceable role in the ecological security of Xinjiang oasis and the sustainable development of social economy. At present, the poplar cultivation area in Xinjiang exceeds 6 million mu. Xinjiang is one of the origins of poplar. There are 13 original species and more than 300 hybrid varieties and strains. Poplar is also the most important cultivated tree species for shelterbelts, timber forests and urban greening in the Xinjiang plains. It is the main tree species for the oasis shelterbelts in Xinjiang plains. It plays an important role in the oasis ecosystem among the three major ecosystems in Xinji...
