In recent years, Chenshanlin Farm in Anfu County, Jiangxi Province has made great efforts to build Chenshanlin Farm into the largest thoroughbred breeding base in the province around the strategies of ecological county establishment, green development and industrial forest development, with the main line of strengthening and improving Chenshanlin brand, and with the goal of building four bases of improved seed breeding, high-quality seedlings, high-quality large-diameter timber and deep processing of products.

Grasp the main line and promote the construction of seedling base

Around the main line of making Chenshan redwood industry bigger, stronger and better, Chenshan Forest Farm focuses on two tasks.

First, based on the whole province, to stimulate domestic demand as a platform, comprehensively promote Chen Shan Sequoia seeds and seedlings. Taking the "one big and four small" construction project of afforestation and greening in the whole province as an opportunity, we will supply Chenshan Toona sinensis seedlings140 thousand plants to the whole province every year; Taking the opportunity of restoring the ecology of the snow and ice disaster areas, we will provide 5500 kilograms of Taxodium ascendens seeds to the whole province every year.

Second, take the project construction as the starting point to strengthen the Chenshan Chinese fir industry. On October 20, 2008-20 10/0, the forest farm completed the implementation of the improved variety selection and promotion construction project of Chenshan red Chinese fir forest. In 2008, the forest farm completed the thinning of parent forest 1.659 mu and built 530 mu of demonstration forest; In 2009, 80 mu of superior trees were selected, and 4 mu of clonal super seedling cutting nursery, 15 mu of superior tree collection area, 124 mu of clonal seedling afforestation comparative test forest, 200 mu of large-diameter timber cultivation demonstration forest and 20 mu of cutting nursery were built. More than 65444 cuttings were collected and produced. This year, 55 mu of progeny test forest, 200 mu of large-diameter timber cultivation demonstration forest, light substrate container bag seedling 10 mu, 250 mu of superior tree stump cutting nursery and 30 mu of clone cutting nursery have been completed, and 250 mu of grafting, budding, shaping and pole setting tasks of the second-generation seed orchard have been completed, so as to enter the fruiting period next year.

Grasp the advantages and innovate to promote the industrialization of seedling production

 Red Heart Cunninghamia lanceolata is a rare Chinese fir, which is a national forest variety and geographical indication protection product in Jiangxi Province. In order to enlarge and strengthen the Cunninghamia lanceolata industry in Chenshan, the forest farm has established joint-stock companies and industry associations to comprehensively promote the coordinated development of the industry.

The forest farm has improved the light, water, fertilizer and sanitation conditions of 4,650 mu of mother forest, continuously improved the genetic quality and yield of seeds, and achieved an annual harvest of 6,000 kilograms of fine varieties of Chenshan Chinese fir.

Forest farms have intensified the cultivation of high-quality seedlings through various preferential policies. In 2008, affected by the global financial crisis, the forest farm adopted the methods of "base+farmers" and "materials+technology", introduced the support measures for walnut seedling cultivation in Chenshan Mountain, and opened 600 mu of walnut seedling bases in Chenshan Mountain area and Henglongdong Valley, and provided more than 30 million seedlings to the whole province and surrounding provinces this spring.

1 1 At the end of last year, Jiangxi Chenshan Hongxinshan Development Co., Ltd., which was established with a capital contribution of100,000 yuan from forest farms and employees, was listed and operated in the county forestry factor market. Anfu County Chenshan Red Heart Abies Industry Association is led by the farm, with the participation of forest farms and large seedling growers all over the world, which has built a bridge between state-owned forest farms, companies and forest farmers. At the same time, the county party Committee and the county government issued the "Implementation Opinions on Accelerating the Development of the Red Heart fir Industry in Chenshan". For the units and forest farmers who use the improved varieties of Abies chenshanhongxin, the county finance will give 400 yuan/mu of improved varieties subsidies; For the units and forest farmers who use high-quality seedlings for afforestation, the county finance gives subsidies to 30 yuan/mu of seedlings.

Focus on key points, carry out publicity, and promote the branding of seedling cultivation.

In order to promote the brand of Chenshan Red Heart fir, the forest farm has set up a scientific research group and a publicity report group. After more than two years, the research group has completed three investigations: Thoughts on the Industrialization Construction of  Red Heart Cedar, Development Status and Development Countermeasures of Red Heart Cedar, and Preliminary Study on the Application of Tobacco Bud Inhibitor Zhuyatong in the Rootstock of Chinese fir Seed Orchard. All papers are published in provincial forestry sci-tech journals. The forest farm has also vigorously promoted the brand of Chenshan Red Heart fir in various forms in the media, constantly enhancing the popularity and reputation of Chenshan Red Heart fir, and the trademark registration of "Chen Shan" brand series products went smoothly.

The origin of Cunninghamia lanceolata in Chen Shan is Chenshanlin Forest Farm, Aoshang Forest Farm and Wugongshan Forest Farm in Anfu County, Jiangxi Province, and it has five towns under its jurisdiction: Pengfang Township, Yangmen Township, Jintian Township, Yantian Town and Yangxi Town.
