Can dead pine trees be used as firewood?

The reason why dead pine trees can't be used for firewood is that pine trees have high oil content. When used for firewood burning, it will produce thick smoke and affect the taste of food. But withered pine is an epidemic tree, so it can't be used as firewood, let alone piled up. The vector insects of Bursaphelenchus xylophilus are hidden in the dead infected trees, so people hoard the infected trees. When the insects appear, the epidemic will spread.

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 three to five years. 65438+February to March is the treatment period of pine wood nematode disease every year.

The growth environment of pine trees

Pine trees have strong adaptability, so they can grow in various types of soil, but the soil will still have a direct impact on the growth trend of pine trees, so we should choose areas with fertile soil as much as possible to ensure the healthy growth of pine trees. If the area is relatively abundant in water, pine trees should be planted in acidic soil as far as possible, but some varieties are still more suitable for planting in alkaline soil.

Most pine trees like light, and their morphology is reflected in sparse crown distribution and strong natural pruning ability, so their compensation points will not be the same as other tree species in physiology. In the process of forest formation, pioneer trees are usually formed. Once the virgin forest is destroyed by external force, the pioneer tree species will develop rapidly and replace the original tree species, but its own stability is not ideal.
