Planting techniques of Zanthoxylum bungeanum

Key points of cultivation techniques: ① asexual propagation, grafting propagation with rootstock 1

② Early spring transplantation is appropriate. Sow in holes after emergence, and apply 3 ~ 4 kilograms of farmyard manure to holes, and the planting density is generally 4 m × 3 m; After planting, the stem is fixed at a height of 40 ~ 50 cm, and sufficient root water is poured to improve the survival rate. Weeds should be removed in time during the growth period to control pests.

(3) In the second year, keep 3-4 branches on the upper part of the trunk as main branches, cut off the branches on the lower part of the trunk, and sparse the vertical branches in the middle part.

④ Apply fertilizer 1 time in early spring or late autumn of the third year, and apply 0.3kg/ plant of chemical fertilizer to 3-year-old seedlings at a distance of 0.5m from the trunk. After entering the fruiting period, attention should be paid to shaping and pruning, cutting off long branches, cultivating happy crowns, and applying chemical fertilizer 0.8 ~ 1.0 kg/plant every year.

Main indicators of dried pepper:? The main indexes of dried Zanthoxylum bungeanum are basically the same as Dahongpao. The positive content was 8.18 0.47 mg/g.

Introduction of Zanthoxylum bungeanum varieties: 1. Dahongpao pepper:

Dahongpao, also known as lion's head, pimple pepper, Qin pepper, wind pepper and so on. It is an excellent pepper variety with wide distribution and cultivation area in China. This variety has strong tree potential, fast growth, compact tree shape, half-open posture, small branch angle, semicircular crown and 3-5 meters high in full fruit stage. The new branches were red, the annual ones were purple-brown, and the perennial branches were gray-brown. The spines are large and sparse, with wide base and sharp tip.

It is suitable for all kinds of soils, especially slopes, and usually grows well in areas with annual precipitation of 600 mm. This variety has strong tree potential, fast growth, early fruiting and high yield. The annual seedling can reach 1.2 meters. If the seedlings are planted, they will blossom and bear fruit in the next year. The fresh pepper per plant can produce 1 kg, and the fresh pepper per plant can produce 3-5 kg in the third year. The fruit is fragrant and hemp is pure. Julia pepper is vulnerable to freezing injury, so attention should be paid to garden selection and overwintering.
