From the forestry sector, i learned about the development of fast-growing eucalyptus trees in guangxi:
The last life
- small and sporadic planting stages (before the 1950s): in 1890, the french missionaries introduced the raisins into longzhou. Later, seeds were introduced in yoozhou, nanning and the north sea. In 1954, the hoipo county established a mountain kibbutz forest farm, which led to the construction of more than 600,000 acres of cervix in the county, but at that time the wood was of limited use, mainly for greening and protection。
- systems seeding, scale development phase (60 - 1990s): in 1965, guangxi established the guinan forestry administration, which created state-run forest plantations and built large areas of americ forest. In 1982-1999, the china-australian technical cooperation east gate elephant demonstration forest project was launched to provide systematic seeding, selection and improvement of various species, sources and families, and to establish a tree plantation and a non-sexual gene pool. By 2000, guangxi eucalyptus forests had an area of about 2. 5 million acres, with a total accumulation of about 2. 2 million cubic metres。
This life
- rapid development, processing and utilization phase (2000-present): starting in 2000, the state and the autonomous communities have made the development of fast-growing forests a priority for forestry, with eucalyptus being the preferred tree species. In 2002, guangxi put forward a proposal to encourage the development of fast-growing forests, which are growing rapidly at a rate of about 2 million acres per year, thanks to their adaptive, fast-growing and widespread use. In 2013, about 30 million acres, with a total accumulation of more than 100 million cubic metres, and the total value of related industries amounted to 10. 5 billion yuan. By the end of 2018, over 35 million acres had been planted in guangxi eucalyptus, and the paper and wood processing industry, with its main raw material, had produced 2395 million dollars annually. Today, guangxi eucalyptus is grown in an area of 45. 5 million acres, or more than half of the country's total, and timber production accounts for one third of the country's total, forming an entire chain of industries, from variety selection to furniture production, and becoming the dominant and supporting industries in guangxi, contributing to the promotion of west forestry with a total production value of 10. 5 trillion in 2024. At the same time, guangxi has been making technological innovations in the cultivation of eucalyptus, such as the construction of a national seed bank for eucalyptus trees and the development of space breeding experiments。
