On the finished border surface, a shallow trench was opened on each side of the border surface with a depth of 6-8 cm, each planting 2 rows. In the open shallow ditch, according to the plant spacing of 10 cm cutting, human soil 2-3 nodes, after planting covered with a layer of thin soil gently compacted, pouring fixed root water.

It is suitable to choose fertile sandy loam and shady and moist land for planting, and it can also be cultivated sporadically in the spare shade wetlands such as the corner next to the house and the edge of Tangba ditch. Apply sufficient basic fertilizer before soil preparation, apply rotten organic fertilizer 2500-3000 kg per mu, rake the soil fine after ploughing, and open the bed according to 1.2m. The width of the box is 90 cm, the width of the ditch is 30 cm, and the depth of the ditch is 20 cm.

If you encounter early days after cutting, you should often drench in water to protect seedlings, once a day to promote rooting and survival. When the cuttings send out new leaves, it is necessary to irrigate light mature human and animal dung water, 30-40 piculs per mu. When the stem vine grows to 12-15 cm, topdressing is carried out again, and 50 piculs of mature human and animal feces are applied per mu. If there is a lack of seedlings in the planting hole, the longer cuttings should be cut to make up the seedlings. After every harvest in summer and autumn, topdressing should be carried out to fully meet the nutrition needed for plant growth and ensure high and stable yield.

At the same time, before applying fertilizer for the second time in the first year, it should be combined with ploughing and weeding once. If weeds grow again, they can be pulled out manually.
