Spring and winter are good seasons for transplanting pepper seedlings. Spring ploughing should be carried out when the buds of pepper seedlings begin to germinate. The cultivation pit should be filled with wet soil first and watered when conditions permit. Winter cultivation is around "beginning of winter". If freezing injury is prevented, the transplant can be cut off, the soil can be piled up after planting, and the soil can be removed after thawing in the next spring. Due to the cold winter in the northern region, it is generally cultivated in spring, and some areas such as Shandong and Qinghai adopt rainy season transplanting.
Selection of Zanthoxylum bungeanum planting site
Zanthoxylum bungeanum should be planted in the middle and lower part of sunny and semi-sunny slopes, with open terrain, deep and loose soil layer and good drainage. Mountain tops, low-lying places where water is easy to accumulate, sandy soil and cohesive soil are not suitable for planting. The pH value of soil is slightly acidic to neutral. Before and after the house, it can be planted by the ditch and the field.
Transplant method
Dig a pit with a diameter of 30 cm and a depth of 25 cm in the selected place, pick out the stones and grass roots in the pit, then fill in a proper amount of wet soil, and then erect the pepper seedlings in the center of the pit, so that the roots of the pepper seedlings can stick out and the soil can be filled in layers. Where conditions permit, root water can be poured after planting.
Tending management
1, intertillage weeding, the root system of Zanthoxylum bungeanum is shallow, "Zanthoxylum bungeanum died that year without weeding", after cultivation, loosen the soil and weed once every spring and summer and after Zanthoxylum bungeanum is harvested.
2, topdressing, mainly applying nitrogen fertilizer from germination to flowering. After fruit setting, phosphorus and potassium fertilizers are mainly used in the vigorous growth period. Organic fertilizer can be applied once after fruit is harvested and before defoliation.
3, plastic pruning
Tree can be cultivated into natural happy shape, cluster shape and round head shape.
Pruning time, after the fruit is harvested, it can be pruned before germination in the next spring.
Before planting, the roots of seedlings can be pruned to cut off the damaged roots. Dip in rooting agent or hymexazol to prevent disease and promote rooting. After planting, pour enough water to make it permeable, and there can be no dry soil layer, especially in water-deficient areas. It is better to dig small pits than dry soil layer. After planting, fix the pole with a height of 40 to 60 cm. It depends on the geographical environment and working conditions.
For example, the rod can be set higher for on-site mechanical operation. Leave more than 4 buds under the incision. Seal the incision with sealant or paint. For small seedlings with insufficient height, leave 5 cm for stubble leveling after weak seedlings are planted, leave 1 vigorous bud after germination, and smooth the rest. Fix the pole when the height reaches 50 to 70 cm before July. Otherwise, the pole will be fixed after defoliation and before germination.
