Suitable soil types are coastal sandy soil, sandy loamy soil, brick red soil and red soil, etc., the soil layer thickness is greater than 60cm, soil pH The value is 4.5 to 8.8. 5.3 Configuration Coastal shelter forests should use rotation-resistant tree seedlings or clones (or strains). Timber forest is fast-growing, stem-shaped straight, trunk The main clones were bifurcation-free, small lateral branches and strong resistance to stress. The method of mixing is strip or block, and the planting area of single clones should be less than 30 hectares. Each county (city) district should use at least 5 to 15 clones of mixed afforestation or plant at least 5% to 10% of the total area per year. Seedlings. 5.4 Afforestation technology 5.4.1 Forest land clearing Fully cut down and remove trees and tall shrubs, and the height of the roots should not be higher than 15cm. 5.4.2 Land preparation 5.4.2.1 Land preparation time It should be completed 1 to 3 months before the afforestation. 5.4.2.2 Land preparation 5.4.2.2.1 Soil For forest land with a slope of less than 15 °, strip-shaped or cave-shaped land preparation is recommended. The size of the hole is 40 cm × 40 cm × 30 cm; for mountainous areas with a slope of ≥ 15 °, The hole size is 50cm × 50cm × 40cm. 5.4.2.2.2 Coastal sandy land The hole size is 30 cm × 30cm × 30cm or 30cm × 30cm × 40cm. Degraded land should be planted with deep seedlings. 5.4.3 Base fertilizer application The base fertilizer for each hole of loam and sandy loam soil is compound fertilizer 150g + calcium superphosphate (12% P2O5) fertilizer 150g. The fertilizer and the soil are evenly mixed; 150 g of superphosphate or 150 g of compound fertilizer is applied to each hole of coastal sandy soil, which can be used to dig holes, fertilize, and mix soil 7 to 10 days before planting. Plant after fertilization, or plant while digging holes and fertilizing. Avoid direct contact with fertilizers. 5.4.4 Initial planting density Pulpwood forests from 2500 to 3333 per hectare, sawn timber and building timber forests from 1100 per hectare, shelter forests from 1600 to 3333 per hectare Strain. 5.4.5 Planting 5.4.5.1 Season Plant in spring or rainy season. 5.4.5.2 Method Remove the non-degradable seedling bag during planting to keep the nutrient soil mass intact and not damage the root system. The seedlings are placed in the center of the planting hole and the soil is compacted. The planting depth is 5cm ～ 20cm higher than the root neck position of the seedlings, which can be appropriately deepened in special sites. 5.5 Replanting Check seedlings and make up shortfalls within 3 months after afforestation.

6 Parenting management

6.1 Young forest tending 6.1.1 Weeding In the summer and autumn of the afforestation year, weeds were used to eliminate weeds in the area of 1m × 1m centered on the plant. Young forest tending for 3 to 4 years, 2 to 4 years In the year, they are raised once or twice. 6.1.2 Topdressing 1 to 3 years old, topdressing once a year during the rainy season, each time applying 100g · strain-1 ～ 250g · strain-1 with compound fertilizer. 0.6m, hole depth 20cm, covering with soil after application, the amount of topdressing increases with the increase of the age of the forest; large diameter sawn timber or building timber is cultivated, and the application is resumed after the fourth Hefei once 250g · plant-1, with a hole distance of 0.8m from the plant and a hole depth of 20cm. The soil layer is particularly deep and the fertility of the forest land can reduce the number of topdressing. 6.2 Forest care 6.2.1 Pruning The stand canopy closure degree is above 0.7.
