Description

Technical Field

[0001] The present application relates to the technical field of forest seedling protection, and more specifically, to a forest seedling protection device. Background Art

[0002] At present, in China, newly planted seedlings after artificial afforestation usually rely on natural transition and recovery. Without any protective measures, newly planted seedlings generally have slow growth, long recovery period and other phenomena. When encountering extreme weather such as drought, high temperature and strong wind, seedling damage and increased mortality will occur, leading to afforestation failure. Experimental studies have shown that taking protective measures such as shading and shielding for newly planted seedlings after afforestation can effectively improve the surrounding environment of seedlings, prevent strong sunlight from burning leaves and new shoots, increase air and surface humidity, reduce wind damage and mechanical damage, and reduce pests and diseases and weeds. In the existing technology, large seedling transplantation and ancient tree protection devices are more common in gardening and greening, such as: sand grass grid afforestation mainly targets the problem of sand being moved by wind, and coastal windbreaks target larger areas of forest protection. However, the protection of individual newly planted seedlings in afforestation is very rare, especially the effective protection of newly planted seedlings of rare and endangered tree species is even rarer.

[0003] A document with prior art announcement number CN 207443714 U provides a simple forest seedling protection device. The device is designed with a support rod, a protective net and a fixed foot, with a stable structure and simple operation. After planting the seedlings, the top of the support rod is connected to the protective net by a binding rope, and the fixed foot is embedded in the ground through the edge of the protective net near the ground, which can effectively shade and protect the newly planted saplings from the effects of high temperature, drought and strong wind in adverse weather.

[0004] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: when the device is used to protect seedlings of different sizes, it requires support rods of different lengths for support and protection, which makes the protection device unable to be applied to seedlings of different sizes.

[0005] In view of this, we propose a device for protecting forest seedlings. Utility Model Content
