Example Embodiment
[0019] The Zanthoxylum bungeanum production process of the present invention is implemented according to the following steps:
[0020] 1. Variety requirements and seed harvesting
[0021] 1.1 Variety requirements: Dahongpao and Bean Pepper native to Feng County.
[0022] 1.2 Seed harvesting and storage
[0023] 1.2.1 Seed harvest
[0024] (1) Seed producing area selection: it is required to collect seeds on the spot and raise seedlings on the spot. If it is necessary to adjust the seeds, they should be adjusted within the scope stipulated by the protection of the origin area of Fengjiao to maintain the purity of the variety.
[0025] (2) Selection of seed-harvesting mother trees: Seeds must be collected from excellent mother trees that grow within the protection range of the original geographical area of Fengjiao. For seed-harvesting mother trees, the topography is sunny, healthy growth, good quality, free of diseases and insect pests, and the fruiting age is 10-15 years old. tree.
[0026] (3) Seed collection time: When the fruit turns from green to red or bright red, the seeds become black and shiny, and a small amount of peel is cracked, it can be harvested. Dahongpao seeds are generally harvested in mid-August, and bean pepper seeds are harvested in mid-to-early September.
[0027] (4) Seed collection method: manually pick or cut with scissors, pick the fruit along with the ears without breaking the branches. After the seeds are collected, the stalks are separated in time to remove impurities and obtain pure seeds.
[0028] (5) Pure species
[0029] After the fruit is harvested, it should not be exposed to the sun directly. It should be placed in a well-ventilated and dry room or spread out to dry in a cool and ventilated place. Use 3 to 4 cm, turn it 2 to 3 times a day, after the peel is dry and cracked, tap it with a small stick to make the seeds come out of the peel. Then put the seeds in a water tank or basin, add water and knead to remove the floating seeds and impurities, and then get pure seeds.
[0030] 2. Seedling breeding
[0031] 2.1 Storage of seeds: The seeds used for spring sowing need to be stored.
[0032] (1) Dry Tibetan
[0033] The seeds that have been soaked in warm water or soaked in alkaline water are dried and stacked in a cool, low-temperature, dry, and non-direct light room.
[0034] (2) Mud cake storage
[0035] The seeds that have been soaked in warm water or soaked in alkaline water are mixed with 4-5 times of loess and sand with water, kneaded and made into mud to form a mud cake with a thickness of about 3 cm. Spread it on the ground with a shade and sunscreen, and then dry it. Stack the mud cakes in piles.
[0036] 2.2 Seed treatment
[0037] 2.2.1 Soaking seeds in warm water: Put the seeds in a jar or other container, pour 60℃ warm water, stir gently with a wooden stick, when the water temperature drops to room temperature, change to clean cold water and continue soaking, change the water daily 1- Two times, after 2-3 days of soaking, remove the floating particles from the water, and finally remove the underwater seeds and place them in the container.
[0038] 2.2.2 Soaking in alkaline water: press 100 kg of seeds, use 1.5-2kg of alkaline surface (sodium carbonate), add appropriate amount of warm water, soak for 3-4 hours, rub repeatedly, remove the oily skin, make the seed shell lose its luster and surface When pitting appears, rinse the seeds with the oily skin removed 2-3 times with water, and spread them out in the shade to dry.
[0039] 2.2.3 Germination of seeds: spring sown seeds need to be germinated before sowing.
[0040] (1) Sand accelerating germination: Mix the seeds with 3 times the wet sand, put them in a cool leeward, well-drained pit, turn once every 10-15 days. 15-20 days before spring planting, move to a warm place with the sun to pile up, 30-40 cm high, covered with plastic film or straw mats, etc., sprinkle with water to moisturize, turn upside down once every 1-2 days, and take out the seeds when they sprout. .
[0041] (2) Hot seeds to accelerate germination: Pour seeds into boiling water 2-3 times the volume of seeds, stir for 2 to 3 minutes and then pour in cold water, adjust the water temperature to 40 to 50°C, soak for 2 to 3 days, and change the water once a day. Then remove the seeds from the water, place them in a warm place, cover with a few layers of damp cloth, and rinse them with clean water 2-3 times a day. After 3 to 4 days, the seeds can be sown when they crack.
[0042] 2.3 Nursery
