I. the advantages of this product

1. It has a wide range of uses. This variety is superior to similar varieties and grabs the fresh pepper market earlier than 40 days. It has the characteristics of high grade, good taste and strong flavor. Vigorously planting nine-leaf green pepper can improve the ecological environment, provide people with more abundant condiments, and also provide high-quality raw materials for the pharmaceutical and chemical industry.

two。 The benefit is obvious. According to the determination, 160 plants of Zanthoxylum bungeanum were planted per 667m2, the yield per plant was 3kg ~ 8kg, the highest was 10kg, and the average yield was 1100 kg per 667m2. According to the conservative data, the yield of fresh pepper per plant is 6 kg per 667m2. According to the current market price, the output value is 3120 yuan per 667m2. After deducting the planting cost, the net income is more than 2470 yuan.

3. Planting is easy. Zanthoxylum bungeanum has developed root system, drought resistance, barren resistance, fast growth, strong resistance to diseases and insect pests, and easy to manage.

2. Cultivation techniques

1. Sow seeds and raise seedlings. Green prickly ash with nine leaves can be sowed in both spring and autumn. Spring sowing is arranged from mid-March to early April, and autumn sowing is carried out before the soil is frozen. The seedling land should be fertilized with sufficient bottom fertilizer, fine and leveled after digging, and watered thoroughly. Germinate the seeds before sowing, and then sow the seeds according to the spacing of 20cm and 25cm. The sowing rate is 0.5 kg ~ 1.2 kg per 67 square meters. After sowing, cover 0.5 cm thick fine soil and cover with plastic film to keep warm and moisturizing. The height of the seedling is 5-6 cm, and the plant spacing is 12-16 cm. Do a good job in fertilizing and raising seedlings, irrigation, ploughing and weeding.

two。 Transplant in time. ① transplanting time. It is suitable to choose from mid-February to March 20 in spring and from September 20 to October 10 in autumn. Planting in autumn is the most suitable. ② reasonable close planting. First, clean land: land with thick soil layer and strong fertility, with row spacing of 2 meters × 3 meters, planting 110 plants per 667 square meters; thin land, planting 166 plants per 667 square meters according to the specification of 2 meters square. Second, intercropping: according to the growth of intercropping plants, 6080 plants are planted every 667 square meters. ③ digging holes for planting. The pit should be dug deep and wide, with a width of 60 cm 70 cm and a depth of 25 cm. Apply enough rotten compost in the pit to cover the local mud. Then put down the seedlings, make the seedlings straight, fill them with fine soil, and finally pour enough water to fix the roots.

3. Reasonable topdressing. Topdressing twice a year. The first time was in the sprouting stage, and the second time was after fruit picking. Fertilization can be done by nest application or ring ditch application, and the nest or ring ditch should be hit at the dripping place outside the tree crown; the fertilizer is mainly human and animal manure, with an appropriate amount of soil testing formula fertilizer, and the amount of formula fertilizer is 0.25 kg ~ 0.5 kg per plant depending on the age of the tree. cover the soil in time after fertilization.

In addition, during the growing period, we should do a good job of disease and pest control, mid-ploughing and weeding, reasonable shaping and pruning, and strengthen ditch drainage in the rainy season.
