Selection of grafting cuttings: the height of one-year-old seedlings is above 1 1cm, and the height of two-year-old seedlings is above 40cm. Selection of seedlings: the height of annual seedlings is more than 25cm.

2. Reasonable planting density

According to site conditions, variety characteristics, tending management level and other conditions, the suitable row spacing is 2.5-3.0m, and the plant spacing is 2.0-3.0m, that is, 60- 120 plants per mu.

3, timely sowing

The survival rate of afforestation in late winter and early spring is relatively high, and it can be from the end of 10 to May of the following year in winter. And planting in spring is better. Planting should be done on cloudy or sunny nights, but not when the soil is too wet in rainy days.

Technical points

1, young tree shaping: first, stem cultivation. Within 1 ~ 2 years after afforestation, all the spring shoots germinated by the terminal buds should be preserved to make them quickly form trunk; The second step is to set up.

The trunk is 60cm high. Choose 3-4 strong main branches around the trunk. The number of auxiliary branches on each main branch depends on the size of the tree and the distance between the two main branches. The most suitable time for pruning is early spring. Remove the bud in time after pruning. Pruning young trees should be light, not heavy.

2. Intercropping forest land: Planting crops, medicinal materials, green manure, etc. with short harvest period between young forest land is beneficial to the growth and short-term harvest of Camellia oleifera and improves economic benefits.

Intercropping crops's choice is based on the principle of not competing with Camellia oleifera for glory, fertilizer and water. Intercropping requirements are 1 m2 reserved for Camellia oleifera. Crops such as peanuts and beans and some green manure plants should be intercropped in Camellia oleifera forest land, but crops with high stalks and vines and high water consumption in dry season should not be selected.
