1. In the first three years after fertilization and transplanting, apply 20 ~ 30 kg of farm manure containing phosphate fertilizer to each plant every spring, and then topdressing 1 time every 1 ~ 2 months, mainly with human and animal manure, and intertillage after fertilization. Before winter, stop applying quick-acting chemical fertilizer, and apply 5 ~ 10 kg burnt soil or 1 kg plant ash per plant to improve the cold resistance of plants. When entering the trial operation date, flower fertilizer should be applied after fruit picking; Applying auxiliary flower attack fertilizer during flower bud germination; Applying fruit attack fertilizer at the early stage of fruit growth; Apply fruit fertilizer during development. Compost, manure and other farm manure and some cake fertilizers are the main fertilizers, and a small amount of quick-acting fertilizers, such as calcium superphosphate, potassium chloride and ammonium sulfate, are added appropriately.

2. Drainage and irrigation should be done well before the rainy season, and accumulated water should be eliminated in time after the rain; Pay attention to irrigation in dry season, cover the border with grass to keep the soil moist.

3. When pulling new vines from columns and pepper seedlings, first insert temporary small columns with bamboo branches; When pruning vines for the second and third time, set up permanent big columns. Columns are cement columns, and stone columns are also used in mountainous areas with many stones. When the new vines grow to 3-4 knots, tie the vines. When tying the vine, the main vine should be tied to the post evenly with soft packing rope or hemp rope, and tied every 10 ~ 15 days/time. Tie the main vine or the vine that is planned to be used as a seedling to each node, so that the suction root on the envoy contacts the post and clings to the post. In this way, plants also need to be tied with vines for 2 ~ 3 times a year, and the newly-grown vines and vines separated from the pillars should be tied again to reduce the harm of wind.

4. Pick flowers and leaves. Pick flowers that bloom in other seasons than the planned flowering period as soon as possible. Flower picking is generally before the peak of 1 ~ 3 years old. Proper removal of dense old leaves and diseased leaves is beneficial to inter-plant ventilation. Picking flowers and leaves is an important measure to coordinate nutrient supply, accelerate tree formation and increase fruit quality and weight.

5. A tree with good shape is the basis of obtaining ideal yield, and shaping is the key to create a high-yield tree. From planting, we should pay attention to the cultivation of trees. Generally, we use the shaping method of leaving 6-8 vines per plant and cutting them for 4-5 times to form a good tree with vigorous growth of main vines, many bearing branches, uniform distribution of branches and large crown width, so that each plant has more than 100 branches and each branch has about 50 bearing branches. Specifically, after transplanting and planting, when the plant grows to the height of 1 ~ 1.2 meters, the vines are cut for the first time at the place 20 ~ 30 cm away from the ground (section 3 ~ 7), and the first 1 layer or the second layer branches are reserved. If the branch order of the first layer is 40 cm above the ground, the empty nodes of the lower new vines can be cut into the nearby soil to press the vines, and 2 ~ 3 sprouted new vines can be left under the incision. When the new vines grown after the first pruning are about 1 m high, the second pruning is carried out, and the third and fourth pruning are carried out in this way. Every time you cut vines, you should choose 4 ~ 6 new vines. The fifth time, start pruning on the second branch sequence. When several main vines are more than 20 ~ 30 cm above the column and close to the center, they can tie knots at the intersection and move 2 ~ 3 nodes away from the intersection, which is called "capping". Plants continue to grow and form cylindrical trees.
