Welcome to ask questions

First of all: 1. Selection of seedbed: Zanthoxylum bungeanum requires sufficient sunshine from the beginning of seedling raising, and the seedbed should be sandy soil with leeward and sunny, deep and fertile soil layer and good drainage.

Carefully prepare the soil before sowing and break the clods, so that the upper part is empty and the lower part is solid. Combined with deep tillage, 4000-5000 kg of decomposed organic fertilizer, 8- 10 kg of urea, 30-40 kg of calcium superphosphate, 50 kg of peat or potassium sulfate 10- 15 kg are applied per mu. On the basis of fine soil preparation, the boundary is 1- 1.2m wide and 6- 10m long.

2. Seedling management: the seeds of Zanthoxylum bungeanum seedlings are unearthed in autumn for a long time, earlier than spring sowing. Therefore, in arid areas or places where the seedbed soil is sticky, plastic film or wheat straw can be used to cover after sowing, and water can be sprayed during drought, but the seedbed soil can not be flooded, and the seedbed soil can always be kept moist. When the seedlings grow to 3-4 cm high and have 3-4 real leaves, carry out thinning, and when the seedling height reaches 10 cm, set the seedlings at a spacing of about 5 cm, leaving 20,000-30,000 seedlings per mu. At the same time, timely irrigation and topdressing, intertillage to improve soil permeability, eliminate weeds in seedbed, control pests and diseases, and ensure the healthy growth of pepper seedlings.

3. Fertilizer and water management: Zanthoxylum bungeanum has developed root system and strong soil and water conservation ability. Soil moisture conservation measures should be taken in arid areas, supplemented by necessary base fertilizer and a small amount of foliar fertilizer to meet the demand of Zanthoxylum bungeanum for fertilizer and water. Generally, organic fertilizers such as ring fertilizer and compost are applied in autumn and spring respectively 1 times. The amount of fertilization depends on the age and fruit yield of the tree, generally more than 20 kg per plant. Top dressing outside the root starts from flowering, about 1 month, 1 time, and is sprayed once in the morning and evening, with a total of 2-3 times.

4. Plastic pruning: Zanthoxylum bungeanum is best pruned in late autumn. When pruning, the redundant branches at the base can be removed, and 3-5 main branches can be retained, and the plastic surgery can be completed in 4-5 years. Finally, the central branch is removed and the cavity is opened. Middle-aged trees should be carefully pruned to remove pests and diseases, horizontal branches and trailing branches in the crown, so that the crown is ventilated and transparent to stabilize the tree. When pruning 25-year-old trees, it is necessary to remove big branches, weak branches and diseased branches, and renew the skeleton of the trees alternately with long branches to ensure a certain yield.

5. Pest control: There are many kinds of pepper pests in China, about 132 species are known, such as scarab, pepper beetle, pepper butterfly, pepper moth, black cicada, pepper aphid, pepper scale insect, pepper spider mite, pepper gall midge and pepper beetle. We should actively prevent and control these diseases and insect pests in actual production.

6. Harvest: At present, fruits are still picked by hand, and leaves cannot be broken. You can't bask in it except the seeds. Generally, in good weather, it can be dried in a day or two. Impurities are removed during the drying process.

Put the dried Zanthoxylum bungeanum (without seeds) into a jar or plastic bag, seal it and keep it for a long time.
