Last month, Liuzhou Municipal Bureau of Forestry took acceptance and evaluation on the growing of China fir seedlings by vegetative propagation and tissue culture in Xishan Forest Farm of Rongan County. It turned out that the success rate of tissue culture exceeds 80%. It is a very high success rate in this industry, showing that the tissue culture experiment is successful.

The prior-period growing on a trial basis in Xishan Forest Farm also shows that tissue-culture China fir seedlings annually grow 2 more meters of plant height, 2 more centimeters of DBH (diameter at breast height) and 20% more effective timber reserves than fast-growing and high-yield China firs, which is called "three 2 standards". The tissue-culture China fir forest is of high quality and high yield, the income from which is 30% higher than that from general China fir forest.

There are 12 forest farms in Liuzhou, of which only Xishan Forest Farm is built with national base for improved China firs. In recent years, Xishan Forest Farm has cultivated 18 improved varieties of China firs under the great support of relevant departments in Liuzhou and Guangxi.

Currently there is 13 million mu field of high forest in Liuzhou, of which 5.3 million mu is for China fir. According to the relevant person in charge of Liuzhou Municipal Bureau of Forestry, the contribution rate by forestry accounts for 35% in the per capita net income of Guangxi farmers based on the calculation of the Department of Forestry of Guangxi Zhuang Autonomous Region. While seriously taking the follow-up experiments, forestry departments of Liuzhou will vigorously build demonstration forests of high-quality China fir and production forests of improved nursery stocks by offering seedlings and popularizing technologies, so as to make greater contribution to the increase in farmers' income of Liuzhou.
