If dead pine trees are used as firewood, the oil smoke is particularly severe, and it is harmful to human body and pollutes the environment, so it cannot be used as firewood. Pine trees are distributed all over the country, with strong adaptability, low requirements for soil, light-loving, drought-resistant and cold-resistant. There are more than eighty kinds of pine trees in the world.
Pines are mainly divided into Pinus massoniana, Pinus tabulaeformis, Pinus bungeana, Pinus tabulaeformis, Korean pine, Pinus densiflora, Pinus thunbergii, Pinus taiwanensis, Pinus yunnanensis, Pinus sylvestris var. mongolica and Cedar. For example, Pinus tabulaeformis and Pinus sylvestris var. mongolica are distributed in Pinus sylvestris var. mongolica, Pinus sylvestris and Pinus densiflora in several provinces of North China and Northwest China, Pinus massoniana, Pinus taiwanensis and Pinus alpine in several provinces of Central China, and Pinus Bashan in Qinba Mountain area.
Dead pine trees can't be used as firewood.
Because pine wood nematodes are hidden in these dead infected trees, people hoard infected trees, and when insects appear, the epidemic will spread. According to reports, Bursaphelenchus xylophilus is an exotic organism that causes the most serious loss of forest resources in China, and its destructive power is extremely strong. Once pine trees are infected with this disease, they can die in about 40 days at the earliest. At present, there is no effective medicine to cure it.
Without human intervention, pine forests can be destroyed in 3-5 years. Since the outbreak of Bursaphelenchus xylophilus disease in Changsha on 20 17, the municipal government has quickly launched the Class III emergency response to forestry biological disasters, and governments at all levels have taken the initiative to undertake the responsibility of compaction, with a total of 6023 personnel, 6023 sets of equipment, prevention and control funds, 0/500,000 yuan and dead pine trees.
