The planting time of Black Lake is in autumn. Sandy soil, humus soil and organic fertilizer are prepared according to the ratio of 3: 4: 2. Choose well-grown seedlings to plant and cultivate them in a warm and humid environment. The seedlings can grow and develop in about 15-20 days. Select the thick stems of plants for cutting, keep a few leaves and insert them directly into the soil for planting.

1. Seedling planting

Seedlings can be planted in Black tiger, and you can choose seedlings that grow well. Plant it in the prepared soil. Autumn planting is the best, and the autumn climate is suitable for the growth of Hei Hu, and the survival rate is relatively high. Black Lake is planted with sandy soil, humus soil and organic fertilizer in the ratio of 3:4:2. Adding appropriate amount of loose bamboo soil can enhance the loose soil with good air permeability. The soil can be changed and ploughed regularly.

2. Cutting planting

Select robust branches, trim and keep the length at 15-20㎝, and disinfect with bactericide. Dry after treatment, insert into the prepared soil, water moderately, and cultivate in a cool and ventilated place. It can grow and develop in about 20 days.

Step 3 put a shelf at the right time

Black tiger seedlings are vines, so we should set up scaffolding at an appropriate time in the second year after planting. The material should be stable and firm, and it is not easy to be blown down by the wind. The scaffold form should be determined according to the planting area and surrounding environment, but no matter what form, it should be oriented up and down. Avoid the orchard from being too closed and improve the air permeability. The height of the support should be kept at about 2m to ensure that Hei Hu has enough climbing space. After the erection is completed, introduce the main rattan of Hei Hu into the scaffold, and then let it grow freely.

Step 4: plastic trimming

Hei Hu trees are relatively large, so pruning is very important for the growth of Hei Hu. Hei Hu trees should be pruned once a season. When pruning in spring, weak fruit branches and old dead branches should be pruned before new buds germinate, and strong fruit branches should leave about 10 buds. Then summer pruning is carried out in June-August. The main pruning objects of summer pruning are basic branches, cross branches and pest branches. Remove branches that are too long and too dense. Adjust the structure of fruit trees, control the growth of main vines, and prepare for the growth in the coming year. In autumn, the base branches are mainly used to improve the cold resistance of Hei Hu trees.
