Embodiment 1

[0026] Such as figure 1 and figure 2 As shown, a biodegradable afforestation device includes a seedling protective film 1 and a pillar 2 for supporting the protective film. The pillar 2 is distributed around the seedlings around the seedlings, and the seedling protective film 1 is set on the Pillar 2 periphery. In this embodiment, the seedling protective film 1 is a white biodegradable plastic tube film connected up and down; the support 2 is a bamboo stick or a wooden stick. The difference between the length of the pillar 2 and the height of the seedling protection film 1 is equal to 20 centimeters. In this embodiment, there are three pillars 2, and they are evenly distributed around the seedlings around the seedlings. The design of this embodiment is reasonable and easy to operate. The protective device including white biodegradable plastic tube film and bamboo sticks or wooden sticks provides a relatively stable micro-habitat for the early survival of the seedlings. As ...

Embodiment 2

[0028] A kind of biodegradable afforestation method utilizes the biodegradable afforestation device in embodiment 1, comprises the steps:

[0029] (1) planting of seedlings;

[0030] (2) select two points around the seedling, insert the first pillar 21 and the second pillar 22 into soil 10-20 centimeters respectively;

[0031] (3) cover the seedling protection film 1 on the first support 21 and the second support 22;

[0032] (4) the seedling protective film 1 is stretched out with the third pillar 23, and the cover surrounds the seedling;

[0033] (5) Adjust the orientation so that the first pillar 21, the second pillar 22 and the third pillar 23 are distributed in a triangular shape, and the seedling protective film 1 is stretched and tightened, and then the third Pillar 23 is vertically inserted into soil 10-20 centimetre; Described seedling protective film 1 is the white biodegradable plastic tube film (diameter 50cm, high 50cm) that communicates up and down; Described f...

Embodiment 3

[0037] This embodiment is a parallel control test of Example 2, and its difference from Example 2 is that the decomposed pine scales are self-produced, and the preparation method of the decomposed pine scales is as follows: collect pine bark, and crush the pine bark to a particle size of 0.5 -1mm, add Bacillus subtilis stock solution to the obtained pine bark powder and mix well, the total concentration of live bacteria in the Bacillus subtilis stock solution is 1×10 12 CFU / mL, the amount of Bacillus subtilis stock solution is based on the amount of water that just oozes out from the pine bark powder, and it is composted for 40 days, during which it is stirred every 5 days and mixed once. The decomposed pine scales produced by ourselves in this implementation can not only retain water and fertilizer, but also avoid injury and disease at the base of seedlings caused by harsh natural conditions, and can prevent pests and diseases at the same time.

[0038] In the spring of 2012,...

Abstract

The invention provides a biodegradable afforestation device and an afforestation method. The biodegradable afforestation device comprises a seedling protection film and supporting columns for supporting the seedling protection film, wherein the supporting columns are distributed around a seedling with the seedling as the center, and the peripheries of the supporting columns are sleeved with the seedling protection film. The seedling is protected by using the afforestation device including the white biodegradable plastic cylindrical film and bamboo sticks or wood sticks, a relatively stable microhabitat is provided for early-stage survival of the seedling, the protection device slowly degrades along with gradual growth and development of the seedling, manual dismantling process is omitted, and afforestation cost is saved. An organic covering is laid at the base portion of the seedling in the protection device, soil moisture evaporation is reduced, weed growth is inhibited, a soil structure is improved, and later growth and development of the seedling are promoted.

Description

technical field [0001] The invention belongs to the technical field of forest cultivation, and in particular relates to a biodegradable afforestation device and an afforestation method. Background technique [0002] Difficult sites refer to site types that are difficult for afforestation. These areas often have arid climate, dry air, lack of vegetation, and strong soil moisture evaporation, which leads to serious water loss of seedlings during afforestation, and rhizomes are prone to sunburn damage. The physiological coordination of aboveground and underground parts Disturbance directly weakens the survival ability of afforestation seedlings, so difficult sites have always been the key target areas for ecological construction and ecological restoration. At present, there are many studies on the selection of suitable tree species for difficult sites, habitat improvement technologies, and vegetation restoration technologies, and a series of key afforestation technologies for d...
