The effective accumulated temperature ≥ 10 ℃ is 5002 ℃. Forest vegetation in the national classification belongs to the subtropical evergreen broad-leaved forest, mainly distributed in the natural evergreen broad-leaved forest, but also part of the natural masson pine forest. The main plantations are Cunninghamia lanceolata forest, masson pine forest, bamboo forest and economic forest. The forest area is 1577.3hm ~ 2, the total volume of standing trees is 130403 m ~ 3, the annual growth of standing trees is 8819 m ~ 3, and the forest coverage rate is 87.2%.

As the earliest forest farm in Zhejiang Province and one of the earliest units in China to carry out the work of improved varieties of trees, Changle forest farm has become the base of improved varieties with the largest number of tree species and area in Zhejiang Province.

Historical process

Since its establishment in 1910, Changle forest farm has gone through 102 years of ups and downs. As early as the early days of the founding of new China, Changle Forest Farm began to introduce slash pine, loblolly pine and other foreign tree species under the guidance of experts from the Chinese Academy of Forestry Sciences, and carried out large-scale planting in the early 1970s, with a planting area of more than 6000 mu and achieved remarkable results.

In 1981, Changle forest farm was listed in the improved variety base jointly established by Ministry, province and farm, and the breeding of improved varieties of forest trees was officially started. After years of experience accumulation, Changle forest farm has developed from the initial timber tree species breeding and greening ornamental tree species breeding to the present national improved variety base involving multiple tree species, multiple types and comprehensive breeding of Cunninghamia lanceolata, slash pine, loblolly pine, etc. They have been approved as Zhejiang Province green tree species breeding center, listed in the national base of improved varieties of Chinese fir and loblolly pine.

The base has an area of 3637 mu, including 932 mu of seed orchard and 411 mu of parent forest. Nearly 5000 germplasm resources have been collected and preserved, 29000 kg of improved forest seed have been produced, and nearly 1.3 million mu of afforestation area has been promoted.

technological innovation

Summing up the development experience of Changle forest farm in the past 100 years, scientific and technological innovation has always been the key word for the leapfrog development of Changle forest farm. For many years, the forest farm has been paying attention to the construction of scientific and technological talent team, providing financial support in scientific research projects, giving priority to family life, and improving the labor skills of technical workers through "inviting in for training, sending out for Internship" and other ways. At the same time, through expert guidance and technology promotion, Changle forest farm's forest breeding work has been successful. In recent years, the survival rate of pine needles and leaves grafting in forest farm is more than 90%, and that of Carya cathayensis is more than 85%.

Moreover, Changle forest farm built more than 1000 mu of slash pine family production demonstration forest in Huanghu forest region in 1994, which fully showed the outstanding effect of improved variety production. When thinning was carried out in 2000, the income of thinning small diameter timber basically recovered the cost of Silviculture and tending. In 2008, slash pine began to cut fat production in the forest area. The net income of Slash Pine only producing fat per 1000 mu per year is more than 1 million yuan, and the net income has exceeded 4 million yuan. According to the estimation of the forest farm, the net income is expected to increase by 2 million yuan this year and next year. Two years later, the pine will enter the cutting period. According to the current volume, the net profit of 1000 mu slash pine wood is expected to reach 10 million yuan.

structural reform

In 1998, Changle forest farm was reformed. After the reform, the forest farm was operated by the company, and the production and management of Changle forest farm has made great progress. In 2010, the company's profit exceeded 10 million yuan and the per capita income of employees exceeded 50000 yuan. Although the nature and identity of Changle forest farm have changed, the importance of forest farm to the construction of improved variety base has not changed. All previous leaders paid close attention to improved seed production, provided the best land for seed orchard and seed forest construction, equipped the best technical personnel for technical posts, equipped the best staff for improved seed production line, increased infrastructure construction and capital investment... The total investment of improved seed base was nearly 12 million yuan.

In 2010, the national key forest improved variety base subsidy pilot work started, which brought unprecedented opportunities to the development of Changle forest improved variety base. Zhang Jianzhong, director of the forest farm, told reporters that in the future, the base will continue to strengthen the construction of fine variety breeding of broad-leaved tree species to serve the development of greening seedling industry in Zhejiang; coniferous tree species will focus on hybrid breeding, further strengthen the breeding of high-yield Pinus tabulaeformis varieties, and speed up the construction of high-yield Pinus tabulaeformis seed orchard.
