Afforestation method of platycladus orientalis in green rocky hill

The invention discloses an afforestation method of platycladus orientalis in a green rocky hill. The method specifically comprises the following steps that S1, firstly, seedling planting pre-treatment is carried out, wherein local high-quality strong seedlings for more than two years are adopted, during lifting of the seedlings, damage roots such as broken roots and peeled roots which have large wound surfaces and are not easy to heal can occur, the roots must be pruned, a shear mouth should be smooth during pruning, and at the same time, overlong main roots are subjected to short pruning. The provided afforestation method of the platycladus orientalis in the green rocky hill has the advantages that the survival rate of the platycladus orientalis in the green rocky hill can be greatly increased, the vegetation coverage is increased, the water and soil loss is reduced, and for limestone mountain regions with lean soil and less water, a soil water-retaining agent is utilized to effectively enhance the water-ret
