It is best to produce less than 100 crops per acre, otherwise the results will not be ideal and picking will be inconvenient if there are too many.

Panthoxylum bungeanum can be propagated by four methods: sowing, grafting, cutting and division. Production is mainly based on sowing and reproduction.

(1) Sowing and cultivation

Seed treatment: Zanthoxylum bungeanum seed shell is hard, oily, impermeable, and difficult to germinate. It must first be degreased and stored before sowing. For autumn sowing, soak the seeds in alkaline water. Use 0.025kg of alkaline surface for 1kg of seeds. Add water to submerge the seeds. Remove the empty shielding seeds. Soak for 2 days. Wash the seed coat oil. Take it out and rinse with clean water before sowing. . For spring sowing, several methods can be used to treat seeds, such as stratified sand storage, cow dung seed dressing, horse dung mixed pile or small cellar storage. Stratified sand storage is the conventional treatment method; cow dung seed dressing is to use 6 parts of fresh cow dung and 1 part of Zanthoxylum bungeanum seeds, mix them evenly, bury them in a pit 30cm deep and store them for the winter. Take them out and smash them together with the cow dung before sowing in the next spring. Sowing; horse manure is mixed and piled from mid-March to mid-April. Mix the water-selected pepper seeds with 3 parts of horse manure and stack them in the sun. Turn them over to expose them and then sow them; for small cellar storage, dig the cellar and fill it with water for winter storage.

Sowing: Sowing is divided into spring sowing and autumn sowing. In areas with spring drought, it is better to sow seeds in autumn before the soil freezes. The seedlings will emerge neatly and 10 to 15 days earlier than spring sowing. Spring sowing time is generally around the "Spring Equinox". Sow 25kg per acre. Small border seedlings can be sown in trenches with 4 rows per border, row spacing 20cm, trench depth 5cm, covering soil 1cm, sowing 4 to 6kg per acre. After sowing, the bed surface is covered with grass to retain moisture, and it is removed in stages after seedlings emerge. Seedlings can also be raised by cultivating ridges. When sowing in autumn, open a trench 1cm deep and 9cm wide every 24 to 27cm. Sprinkle the seeds evenly into the trench. After sowing, cultivate the soil on both sides on the trench. After the beginning of spring, check the germination status of the seeds in time. If you see a few cracks in the seeds, scrape off part of the covering soil and keep 2 to 3cm. After 5 to 7 days, when most of the seeds have cracks, scrape off part of the covering soil and keep the covering soil about 1cm thick. In this way, the seedlings Will be out soon. For example, if seeds are sown in spring and have undergone germination, the seedlings will be unearthed 4 to 5 days after sowing, and all the pepper fruits will emerge in about 10 days. This method is suitable for areas prone to early spring.

Management in the seedling stage: When the seedling height is 4 to 5 cm, the seedlings should be fixed and the distance between seedlings should be maintained at 10 to 15 cm. During the growth period of seedlings, 3000-4500kg of human excrement or 10-25kg of chemical fertilizer can be applied per acre from June to July. Fertilization should be combined with irrigation, and timely cultivating and weeding after application. Zanthoxylum bungeanum seedlings are most afraid of waterlogging. When the rainy season arrives, nurseries must prepare for waterlogging prevention and drainage. One-year-old seedlings are 70 to 100cm tall and ready for afforestation.

(2) Grafting seedlings

Generally, bud grafting and branch grafting are used. Bud grafting is mostly done in the shape of "T" or "Z". Split grafting, cut grafting, ventral grafting and other methods are commonly used for branch grafting.

(3) Cutting seedlings

In 5-year-old seedlings, From the following Zanthoxylum bungeanum trees that have produced fruit, 1-year-old branches can be used as cuttings. The cuttings can be soaked in 500 mg/L indole acetic acid for 30 minutes, or 500 mg/L naphthalene acetic acid for 2 hours. The root treatment method can also be used. The cuttings have a high rate of rooting and seedlings.

(4) Propagation and cultivation of seedlings by divisions

Before the pepper sprouts sprout, girdle the base of the 1 to 2-year-old tiller seedlings and bury them in the ground. In the soil, let new roots grow from the peeled opening. After one growing season, separate the tiller seedlings from the mother plant, and they can be used for afforestation. Another method is to cut off 2/3 of the base of the tiller seedlings with a sharp knife. Then cultivate the soil and take root. After the tillering seedlings are cut from the mother plant, if the root system grows well, they can be transplanted directly. If the root system does not grow well, they can be planted in a nursery and transplanted after the new roots develop.

(5) Circle branch nursery

In spring, when the temperature gradually rises and the water is sufficient, select one-year-old branches that are strong and free of diseases and insect pests, and cut them crosswise to the xylem with a sharp knife ; Then pull it upward about 15cm, then pull the cut half away from the branch, and insert it into the ceramic pot. First make a hole in the bottom of the pot, fill the pot with fertilizer mud, tie the pot firmly to the branch, and then add it to the pot. Pour enough water and seal the tank surface with brown sheets so that natural rainwater can soak the tank soil.

Next year, when the cut branches have grown more fibrous roots, they can be cut and transplanted.
