How to plant prickly ash seeds?

Zanthoxylum bungeanum, also known as Zanthoxylum bungeanum, etc., are deciduous shrubs or small trees of the genus Zanthoxylum bungeanum in Rutaceae, which are widely distributed in China. They are from the south of northeast, south to the north slope of Wuling, southeast to Jiangsu and Zhejiang coastal areas, southwest to the southeast of Xizang, and are not produced in Taiwan, Hainan and Guangdong. Let's take a look at how to plant pepper seeds.

Zanthoxylum bungeanum seed harvest

The harvest season of Zanthoxylum bungeanum is generally from August to September, and it is also a good time to raise seedlings and collect seeds of Zanthoxylum bungeanum. At present, the main varieties to be popularized are Dahongpao (Lion's head), Xiaohongbao, Golden Pepper, Oil Pepper and so on. Middle-aged trees with strong tree potential, fruiting and good quality should be selected. When harvesting, Zanthoxylum bungeanum is fully ripe, the fruit skin is purple-red, and the seeds are blue-black, full, disease-free and insect-free.

Zanthoxylum bungeanum seed treatment

The newly collected seeds of Zanthoxylum bungeanum were first selected with clean water to remove the blighted seeds, then soaked in 1% alkali water or 1% washing powder solution with warm water for 2 days (it is appropriate to submerge the seeds with water), and the oil on the seed coat was scrubbed repeatedly until the seed surface was grayish white. After being removed, rinse the lye on the seed coat with clean water, mix it with plant ash and sow the seeds.

Selection of Zanthoxylum bungeanum seedling bed

Zanthoxylum bungeanum requires sufficient sunshine from the seedlings, and the seedling bed should choose sandy soil that is leeward, sunny, deep, fertile and well drained. Fine soil preparation before sowing, break the clods, so that the upper virtual and the lower solid. Combined with deep ploughing and soil preparation, 4000kg of rotten organic fertilizer, 8kg of urea, 30kg of superphosphate, 50kg of charcoal or 10kg of potassium sulfate were applied per mu. The border is made on the basis of fine soil preparation, with a width of 1 to 1.2 meters and a length of 6 to 10 meters.

Zanthoxylum bungeanum seed sowing

In the prepared seedling bed, the furrow spacing is 20 cm 25 cm, the depth is 4 cm 5 cm, the width of the ditch is 8 cm 9 cm, the bottom of the ditch is flat, the seeds are evenly scattered into the ditch, and the soil is cultivated on the ditch. After the beginning of spring the next year, check the germination. When a small number of seeds break the soil, scrape off the upper cover soil, leaving the soil cover 3 cm. When the seeds break more than 80%, scrape the soil again, leaving 1 cm 2 cm, and the sowing amount per mu is 5 kg. The sowing date should be before the soil is frozen, usually from mid-October to early November, and prickly ash producing areas can sow seeds immediately after seed collection from mid-late August to early September.

Management of Zanthoxylum bungeanum at seedling stage

The seedling seeds of Zanthoxylum bungeanum bungeanum were unearthed for a long time in autumn, which was earlier than that of spring sowing, so in arid areas or where the soil of the seedling bed was heavy, plastic film or wheat straw could be used after sowing, and water could be sprayed during drought, but it could not be flooded, and the soil of the seedling bed was often kept moist. When the seedlings grow to 3 ~ 4 cm high and have 3 ~ 4 true leaves, the seedlings are fixed when the seedling height reaches 10 cm, and the seedling spacing is about 5 cm, leaving 20 ~ 30 000 seedlings per mu. At the same time, timely irrigation and topdressing, ploughing and loosening soil, improving soil permeability, removing seedbed weeds, controlling diseases and insect pests, and ensuring the healthy growth of Zanthoxylum bungeanum seedlings.
