Affected by extreme rainfall this summer weather, the Greater Xing'an coniferous and deciduous tree large epidemic outbreaks of severe leaf diseases, the end of August, more than 100 acres of pine, poplar, willow, birch serious disease.
It is understood that a large outbreak of woodland leaves fall off, to affect tree growth. Main disease categories include larch caducous disease, pine canker, rust pine needles, pine needle disease, black spot birch, poplar leaf rust and so on. Killing 20 million cubic meters volume loss, reducing carbon sequestration capacity of over 100 tons, reducing oxygen release reached more than 120 million tons. If the further spread of the epidemic disease, will cause periodic borer pest invasion times, resulting in a large number of dead trees.
It is understood that since the summer, forest precipitation is more than one times more than last year, temperature, humidity, especially for bacteria mature, release, invasion, colonization, diffusion. Forest stand structure in a large proportion of young forest less able to resist disease, vulnerable to pests and diseases. After entering the tourist season, increased vehicular traffic on the highway, road sides and air circulation speed rail on both sides in the forest, exacerbating the spread of pathogens.
According to the Forest Authority Senfang terminus responsible person, in order to prevent further spread of the epidemic spread around the forest protection station is to strengthen the monitoring, to grasp the occurrence of disease, the timely release forecasts, and road, rail sides and place inside the scenic forest diseases of coniferous and deciduous tree to take sprays and cast smoke manner control, to ensure that key regional ecological security. While doing Pharmacy, Medical Device reserves, according to this year, the occurrence of forest disease outbreaks, analysis and judgment to do next year to prepare forest pests and diseases.
Greater Xing'an is China's largest state-owned forest, forestry is also a high incidence of pests and the hardest hit, because a sudden pest outbreaks have caused the destruction of 13 acres of larch. Forest forest land area of 8.31 million hectares, the current outbreak of a large area of forest disease outbreak, and every year into the forest pest's limited funds. Forest Pest sector infrastructure is weak, grassroots monitoring, prevention and control capacity is weak, control equipment behind, inadequate monitoring costs, a larger gap and other issues still exist.
