Embodiment Construction

[0025] 1. Reclamation of flat hazel forests on barren hills and slopes

[0026] A. Reclamation of the original contiguous flat hazel forest

[0027] The original contiguous flat hazel forests on the barren hills and slopes should be cleared except for 10% of the miscellaneous shrubs (mainly peduncle and Amorpha fruticosa), so as to avoid competition with the flat hazel forests for fertilizer and water, improve the light, and promote the growth of the flat hazel forests Robust, increase the amount of flowering and fruiting; individual miscellaneous trees (arbors) and wild fruit trees (Shanlihong, Shanli, etc.) Manage according to the conventional method of fruit trees; for partial bare land, it should be transplanted before freezing, and the stubble should be flat after transplanting. When transplanting, it must be stepped on firmly, and then covered with 3cm to 4cm of moisture-retaining soil. When replanting, it is not advisable to replant nearby, and it should be cross-trans...
