Key points: 1. Comprehensive elimination Clean up other mixed forests, miscellaneous vines, vines, weeds, and tree shrews in the Camellia oleifera forest. Point two, density adjustment 1. For oily tea forests with good forestry, small age, and dense distribution, only 74-90 trees with good tree vigor and more fruit bearing are reserved per acre; only 40 trees/mu can be reserved, and then each acre is added. Plant 50 strains of 3-4 years old seedlings. 2. For the young trees with sparsely distributed sparse forests, replant 3-4 years of mature seedlings for the sunroof. The total number of plants after replantation was controlled at 74-90 plants/mu. 3. It is recommended that all kinds of Camellia oleifera are well-established for trees with older ages and no significant potential for yield increase. Three points, pruning The low-reforming oil camellia forest is basically the oil camellia forest in fruit period. The pruning is mainly to make the tree three-dimensional results, ensure the light of the inner part and the lower part of the canopy, and do not make the result part move outwards every year, while the inner part and the lower part are bald. . Maintain the affiliation of the main branches and sub-branch branches and the solidity of branches and branches. 1. Pruning of the old year tree. The degree of pruning should be heavy, and a part of the result branches can be deleted and shortened to reduce the amount of results and promote new shoots. Summer shoots can be cut off. 2. Pruning of young trees. Keep as much as possible the annual branches that were drawn during the previous year, even if the branches in the shorter and shorter positions are not good. Postpone trimming and try to preserve the resulting branch. Keep stout leafy pedicles after harvesting last year. Only weak, dense branches, pests and branches, and leggy branches are eliminated. 3. The renewal pruning of aging trees. It is mainly to strengthen the water and fertilizer management, prevent and treat pests and diseases, and to update according to tree vigor, to promote the germination of secreted buds, to attract new shoots, and restore the tree vigor and yield. Point four, dig again "Digging gold in winter and digging silver in summer." It is better to use the winter and summer seasons as the breeding grounds, but in different seasons, there are different methods for restoration. The method of recovering in winter is a thorough excavation. It is usually 20-30 cm, and it will regenerate into a large block for winter. In summer, it is shallow and its depth is generally 10-15 cm, which is based on the principle of not damaging the root. Point five, rational fertilization Fertilization mainly organic fertilizer, supplemented by chemical fertilizers. Phosphorus and Potassium fertilizers are the main components in the Da Nian Year, and nitrogen fertilizer or compound fertilizer is added in small years. Autumn and winter are dominated by organic fertilizers, and quick-effect fertilizers can be applied in spring and summer. Fertilizer amount: nitrogen fertilizer 10-15 kg per mu, phosphate fertilizer 30-50 kg per mu, potassium fertilizer 10-20 kg per mu, soil miscellaneous fertilizer 300 kg per mu. Fertilization method: combined with wolfberry complex, fertilize in the trench along the outer edge of the crown.
