Reasonable fertilization. Generally should be applied in the winter base fertilizer, base fertilizer to farmyard manure, supplemented by a small amount of chemical fertilizer. The method of applying the base fertilizer is to dig a 30 cm wide, 40 cm deep fertilization hole at the edge of the canopy spread, mix the fertilizer with the topsoil and apply it to the hole, step and irrigate. In the spring new growth period can be fertilizer, fertilizer to compound fertilizer-based, can be dug around the crown of the hole or ditch, ditch depth of 15 cm, sprinkle fertilizer and then cover the soil.

Shaping and pruning. In order to better promote the growth and fruiting of oil tea, shaping and pruning. The general principle is to maintain a balanced tree, more branches but not dense. Too big and too strong branches can be used behind the branch for the head, so that the same layer of branches of similar height, the upper and lower layers of overlapping branches to maintain a distance of 60 centimeters, the distance is not enough to be thinned out. In addition, it is necessary to remove competing branches, inward branches, back upright branches, cross branches in the inner chamber, too dense branches and weak branches, so that the canopy ventilation and light, in order to form more flower buds, fruit bearing more.
