On the planting methods and matters needing attention of Zanthoxylum bungeanum

Prickly ash is a common seasoning in daily life, and it is one of the essential ingredients for hot pot. There are a lot of people growing pepper, so what are the methods and matters needing attention about growing pepper?

I. planting method of Zanthoxylum bungeanum

Zanthoxylum bungeanum can be propagated by sowing, grafting, cutting and ramet. Sowing and reproduction are the main methods in production.

1. Sowing: the seed shell of Zanthoxylum bungeanum is hard, oily, impervious and difficult to germinate. Skim treatment and storage should be carried out before sowing. Soak the seeds in alkaline water, then wash them and sow them.

two。 Grafting: generally use bud grafting and branch grafting. Buds are often grafted with "T" shape, "Zhuan" shape, and branch grafting is often used in split grafting, cutting grafting, ventral grafting and so on.

3. Cuttage: one-year-old branches are selected as cuttings on prickly ash trees that are less than 5 years old. The cuttings can be soaked in 500mg/L 's indole acetic acid for 30 minutes or 500mg/L 's naphthalene acetic acid for 2 hours, or by hotbed rooting. The rate of rooting and seedling formation of treated cuttings was high.

4. Ramet: before the prickly ash germinated in spring, the base of the 1-2-year-old tillering seedling was girdled and buried in the soil, and the peeling mouth was allowed to grow new roots. after one growing season, the tillering seedling was separated from the mother plant, which could be used for afforestation. Another method is to cut the base of tiller seedlings by 2 / 3 with a sharp knife and then cultivate the soil to take root. After the tiller seedlings are cut away from the mother plant, if the root system grows well, it can be transplanted directly, and if the root system does not grow well, it can be pseudo-planted in the nursery and transplant after more new roots.

II. Points for attention

1. Overwintering management: water and fertilizer management in autumn, Zanthoxylum bungeanum trees should stop topdressing nitrogen fertilizer after entering July to prevent excessive growth in the later season. At the same time, the base fertilizer should be applied as early as possible from September to October, which is beneficial to improve the nutritional level of the tree.

two。 Pruning: pruning in time with pepper harvested in summer. Cut off part of the big branches and disease and insect branches of the weak tree, remove the extra big branches in autumn, and finally retain 5-7 main branches per tree, at the same time properly remove the dense branches in the crown, the amount of sparse branches generally does not exceed 25%, and cut part of the weak branches to the strong bud; the medium and short branches of the mediocre tree are generally not short, mainly sparse, and pay attention to protect the terminal bud, cut the long fruit branch properly, and retain the big bud.

3. Fertilization: fertilization before and after flowering is the most important stage, of course, fertilizer should be mainly nitrogen fertilizer, this is mainly because those nutrients in nitrogen fertilizer can increase the fruit setting rate of Zanthoxylum bungeanum, if some fertilizer is applied before pepper blossoms, then it can supplement the low fruit setting rate in the later stage caused by lack of nutrition in the tree, so if topdressing is carried out again after flowering. It can effectively ensure the nutritional needs of Zanthoxylum bungeanum fruit in the process of growth and development, of course, the fertilization of Zanthoxylum bungeanum after flowering should be a little bit, and a little phosphorus and potassium fertilizer should be added in the process of fertilization.

The cultivation of Zanthoxylum bungeanum is relatively simple, according to its growth, some appropriate management can be made.
