Seed price and planting method of Zanthoxylum bungeanum

Zanthoxylum bungeanum, also known as big pepper, Qin pepper, Shu pepper, etc., is a small deciduous tree of Rutaceae, which is widely cultivated in various parts of our country, and its pericarp can be used as a seasoning and can extract aromatic oil. it can also be used in medicine, such as warm gas, cold pain, insecticidal and other effects. seeds are edible and can also be processed to make soap. let's take a look at the seed price and planting method of Zanthoxylum bungeanum.

How much is the pepper seed per jin?

The price of Zanthoxylum bungeanum seed is about 4-6 yuan per jin, but it varies according to the quality, variety, origin and market of the seed. Zanthoxylum bungeanum is suitable for warm, humid and deep fertile loam and sandy loam, with strong sprouting and tillering, cold tolerance, drought tolerance, like sunshine, strong disease resistance, long hidden bud life, but not resistant to waterlogging. Propagation methods include sowing, grafting, striping, cutting and other methods, but seed propagation is often used in production, because prickly ash seed propagation is simple and easy, and the reproduction coefficient is large, so it is suitable for large-scale production.

What kinds of pepper do you have?

1. Dahongpao: Dahongpao, also known as Lion head, Big Red Pepper, bumpy Pepper, Qin Pepper, Wind Pepper and so on, is an excellent variety of Zanthoxylum bungeanum, which is widely distributed and cultivated in China. Now the cultivation is concentrated and has formed a scale in Wudu District and other places in Longnan, Gansu Province.

2. Big red pepper: big red pepper, also known as oil pepper, Erhongpao, Erxian, etc., with medium-strong tree potential and open posture, is cultivated in northwest and North China, but it is most concentrated in Hanyuan, Luding, Xichang and other places in Sichuan.

3, small red pepper: small red pepper also known as small red hug, rice pepper, small pepper, ponytail pepper, etc., the tree potential is moderate, the tree posture is open, the branch angle is large, the crown is flat and round, the pericarp is red and bright, the hemp flavor is rich, especially the fragrance is strong, the quality is excellent.

4. White sand pepper: White sand pepper, also known as white pepper, white sand, etc., the tree potential is moderate, the tree posture is more open, the high yield and stable yield are strong, but the skin color is poor, the market sales is not very good, and it is not suitable for large-scale cultivation. Cultivation is more common in Shandong, Hebei, Henan and Shanxi.

Sowing method of Zanthoxylum bungeanum

1. Seed harvesting: middle-aged trees with strong, fruiting and good quality should be selected for seed harvesting, and pepper with full maturity, purplish red fruit skin and blue-black, full, disease-free and insect-free seeds should be selected when harvesting.

2. Seed treatment: the seeds of Zanthoxylum bungeanum were selected with clear water to remove the blighted seeds, then soaked in 1% alkaline solution prepared with warm water for 2 days, and the oil on the seed coat was scrubbed repeatedly until the surface of the seed was grayish white. After being removed, rinse with clean water and mix with plant ash to sow.

3. Nursery bed selection: the seedling bed of Zanthoxylum bungeanum should be sandy soil with leeward and sunny, fertile soil layer and good drainage. Combined with soil preparation, 4000000kg / mu of mature organic fertilizer, 8kg / 10kg urea, 30kg / 40kg superphosphate and 50kg of charcoal should be applied, and then make the border.

4. Sowing time: the sowing time of Zanthoxylum bungeanum should be before the soil is frozen, usually from mid-October to early November. In the producing areas of Zanthoxylum bungeanum, the seeds can be sowed immediately after seed collection from mid-late August to early September.

5. Sowing method: when sowing, Zanthoxylum bungeanum is ditched in the seedling border, the bottom of the ditch is flat, the seeds are evenly scattered in the ditch, the soil is cultivated on the ditch, the upper part of the soil is scraped off when a small number of seeds break the soil after the beginning of spring, and the soil is scraped again when the seeds are broken by more than 80%. The sowing amount is 5kg / mu.

6. seedling management: pepper can be covered with plastic film or wheat straw after sowing, and can be sprayed with water during drought, but it can not be flooded, and the soil of the seedling bed is often kept moist. When the seedlings grow to 3 cm 4 cm high with 3% 4 true leaves, the seedlings are fixed when the seedling height reaches 10 cm.

Planting method of Zanthoxylum bungeanum

The main results are as follows: 1. Garden selection: Zanthoxylum bungeanum has small plants, shallow root distribution and strong adaptability. it can be planted on idle land such as barren hills, wasteland, roadside, front and back houses, but not on hilltop, low-lying terrain, tuyere, thin soil layer, bare rock or heavy clay.

2. Soil preparation and fertilization: Zanthoxylum bungeanum needs soil preparation before transplanting, while applying sufficient basic fertilizer, applying 40.5 tons per mu, and mixing about 20,25 kilograms of organic fertilizer when backfilling. Soil and water conservation must be done well in soil preparation in hilly and mountainous areas.

3. Planting density: Zanthoxylum bungeanum should be planted sparsely but not densely. The adult density should be in the range of 100,120 plants per mu in dry and semi-arid areas, and about 60 plants per mu in areas with deep soil layer, good soil quality and moderate rainfall.

4. Timely planting: planting of Zanthoxylum bungeanum is the key to survival. The survival rate of planting is the highest at the beginning of bud germination, which should be watered thoroughly after planting, topdressing 2-3 times in growing season, and combined with watering in drought.

5. Fertilization management

① hole expansion fertilization: after the soil was thawed in early spring, the soil around the root system of Zanthoxylum bungeanum was planed 30kg to 50cm, about 30kg of organic fertilizer was applied to each plant, and 0.4kg of standard chemical fertilizer was applied to each plant during the budding period in mid-April and after fruit harvest in late July.

② foliar fertilizer spraying: spraying fertilizer 6 times a year with a mixture of 3% potassium dihydrogen phosphate and 0.5% urea, the first time at flowering, the second time at 10 days after flowering, the third time at intervals of 10 days, and once in early, mid-July and after fruit harvest.

6. Pruning and rejuvenation: pruning Zanthoxylum bungeanum in combination with harvest in summer, cutting off some big branches, disease and insect branches of weak trees, and finally retaining 5-7 main branches per tree, while properly thinning dense branches in the crown, the medium and short branches of the mean tree are mainly sparse.

7. Timely harvest: the ripening period of Zanthoxylum bungeanum is generally around the Beginning of Autumn to the End of Heat. When it is ripe, the pericarp is purplish red or light red, the pericarp sutures protrude, a small amount of cracking, the seeds are black and bright, and strong hemp aroma can be smelled. This is the most suitable harvest time.

① strong branch picking: there is a full bud in the axilla of the first leaf under the big pepper ear, this bud is the fruit bud of the next year, it should be properly protected, and the axillary bud must not be removed when picking the pepper ear, so as not to affect the annual yield in the coming year.

② weak branch picking: the first bud under the weak branch ear is not full, and the second or third bud is more robust, so the second or third bud should be retained when picking, otherwise the yield of the second year will be affected.
