The efficient management technology of Chinese fir forest
Pine gymnosperm, Firaceae, Cunninghamia. It is a unique species of fast-growing wood grown in China. It grows fast and is of good quality. In my town, artificially grown firs cover an area of ​​about 40,000 mu. However, most of the farmers planting Chinese fir are extensively managed and have a long growth cycle. The following describes the efficient management techniques for Chinese fir forests: 1. Place base fertilizer when planting. The requirements for the use of Chinese fir are comparatively extensive. As long as there is fertilizer, it can grow. It is recommended that about 0.2 kg of fertilizer should be placed under the planting hole, lightly soiled, and then planted. 2. Weeding once a year for the first three years. In the first three years of planting, because the Chinese fir seedlings are relatively short, they need to be sprayed with herbicide to remove the forest weeds. When the Chinese fir seedlings are about 4 meters high, they can be used without weeding. 3. Apply fertilizer once a year for the first three years. The first three years after planting must be fertilized, about 0.2 kg per plant, to promote fir head.
