Second, the site conditions

Within the range of origin, the altitude is 800 meters to 1500 meters, the soil layer is deep, loose and fertile, and the pH value is 4.5 to 7.

Third, cultivation management.

1. Seedling raising: excavate mature bamboo forests in the place of origin. Choose two-year-old seedlings. The seedlings are required to be robust, with normal color, no pests and diseases, and no mechanical damage. Specification: height 100 cm, ground diameter 2 cm.

2. Planting: Transplanting afforestation is generally from the end of September to the end of February of the following year. During this period, no land preparation or afforestation is allowed until the snow and ice have thawed. The planting density is less than or equal to 1600 plants/hectare, and the planting point configuration can be determined according to the mountain situation, generally in plum blossom shape. The key points of afforestation technology are "big hole, flat whip, shallow planting and sealing"

3. Bamboo forest management:

(1) Young forest management: loosening soil, weeding and fertilizing, mainly using organic fertilizer or applying green manure, suitable for summer and autumn every year; Irrigation and drainage; Tending and thinning are carried out according to the principle of "keeping small and big, keeping old and tender, keeping secret and keeping thin, keeping weak and keeping strong"; Intercropping between bamboo and farmers can be carried out in newly-built bamboo forest 1 ~ 3 years, and farming can replace tending.

(2) Forest management: adjust the density of standing bamboo, and control the standing bamboo degree at 3,500 ~ 4,500 plants per 667m2 (mu); Adjust the age structure of the stand, and cut down all the standing bamboos over five years old. Protect bamboo shoots and raise bamboo; Protect the canopy with a canopy density of 0.4 to 0.5.

4. Environmental and safety requirements: The use of pesticides and fertilizers must comply with the relevant provisions of the state and must not pollute the environment.

Fourth, picking bamboo shoots.

From early August to late September, bamboo shoots are picked about four days after they are unearthed. The height of bamboo shoots depends on the diameter and forest quality, and the ratio of height to diameter is 10 ~ 15: 1.
