development direction

In the future development of the forest farm, first, through the definition of classified management division, the forest with ecological benefits as the main purpose is divided into ecological public welfare forest, scientific management, the pursuit of maximum ecological and social benefits; the forest with economic benefits as the main purpose is divided into commercial forest, to improve forest productivity, the pursuit of maximum economic benefits. Second, relying on the local resource advantages, we should develop and utilize the wild vegetables, edible fungi, medicinal plants and other mountain products in a planned and organized way; at the same time, we should actively use the forest resources, vigorously develop the planting and breeding industry, and cultivate Chinese medicinal materials, economic crops, edible fungi, and forest frog breeding projects.

development projects

The economic forest of Schisandra chinensis covers an area of 30 hectares. It not only cultivates seedlings, but also produces berries. Raising domestic chickens in woodland and allowing domestic chickens to grow in semi wild state can produce pure green stupid eggs and small stupid chickens. Increase the number and area of Rana chensinensis. Relying on natural advantages, we should develop planting and breeding industry. director of Forest Farm: Jin Rongzhang
