Drought-tolerant, but it should not be allowed to dry, and the requirements for soil are not strict, but loose and fertile soil grows better in places that avoid water. More resistant to pruning, cold, but afraid of cold. The suitable growth temperature is 65438 08 ~ 25℃.

Zanthoxylum bungeanum originated in Japan and distributed in south-central China, southwest China and Hebei Province.

V. Breeding methods

Propagation methods include cutting propagation and high pressure propagation, which should be carried out in spring.

Six, cultivation techniques

1 pot soil mixing: the nutrient soil of potted Zanthoxylum bungeanum can be mixed with 7 parts of garden soil, 3 parts of slag and an appropriate amount of fully decomposed organic fertilizer.

2. Transplanting to the upper pot: When transplanting seedlings, choose a flowerpot with appropriate size, cover the hole at the bottom of the pot with two tiles, put coarse sand with a thickness of 2~3 cm, then put nutrient soil and plant seedlings. Water is poured once after the basin is put on, and it is maintained in the shade environment 1 week.

3 lighting control: Zanthoxylum likes lighting environment. Adequate sunshine should be given in autumn, winter and spring, and proper shade should be provided in summer. When curing Zanthoxylum bungeanum indoors, it should be placed in the living room, bedroom, study and other well-lit places as far as possible, and frequently exchanged with the outdoor environment, that is, indoor curing is about 1 month, and then moved to the outdoor shade for the same time to prevent the leaves from turning yellow or even falling off due to insufficient light.

4 Temperature control: The suitable growth temperature of Zanthoxylum bungeanum is 18~25℃, and it will stop growing below 10℃. In summer, when the temperature is higher than 35℃ and the relative humidity is higher than 80%, attention should be paid to ventilation and cooling. Indoor wintering temperature should not be lower than 5℃.

5 fertilizer and water regulation: Zanthoxylum bungeanum likes a slightly humid climate with a relative humidity of 50~70%. Water every 2~3 days in spring, summer and autumn 1 time. When watering for the third time, the diluted organic fertilizer which is fully fermented and decomposed should be applied with the water, and then the first three measures of fertilizing and watering should be repeated in turn. In this way, circulating watering and fertilization can meet the growth needs. The interval of watering and fertilization is shorter in sunny days or high temperature periods, and longer in rainy days or low temperature periods or without watering. During the winter dormancy period, we should control the fertilizer and water, keep the basin soil slightly wet, and avoid being wet for a long time.

6 Winter management: When Zanthoxylum bungeanum plants enter dormancy or semi-dormancy, they should cut off branches that are sick, insect, dead, too dense and too thin. When the plants grow vigorously in late spring and early autumn, the branches can be pruned and reshaped in combination with cutting.

Precautions: Diseases: mainly "leaf blight", which occurs frequently in July 7- 10/0, especially in poorly ventilated environment, which is easy to happen. The diseased leaves should be pruned in time and then treated with thiophanate methyl or carbendazim. Insect pests: "Aphids" and "Starscream" are common and can be controlled by omethoate and other solutions.
