Cultivation of Dried Pepper in Alpine Area
Finished Products of varicella vaccine. It has three qualities,good safety of gelatin-free, long validity period by good stability, better protection with high titer and immune efficacy. These improvements enhanced the vaccine safety and quality, and established BCHT the leading position in varicella vaccine. We have two different packages, penicillin bottle and pre-filled syringe. And it has been exported to other countries, such as India, Philippines.

Second, the environmental requirements
1. The temperature requirements Pepper germination temperature is 25 °C, less than 15 °C can not germinate, the optimum temperature during the growth period of 20 ~ 26 °C during the day, night 15 ~ 17 °C. During the results, the ground temperature is too high and will inhibit root development.
2. Requirements for moisture The root system of pepper is underdeveloped. The root group is in a layer of 10 to 15 cm in diameter, and it is not tolerant to drought or intolerant to waterlogging. If it is flooded for several hours, the plants will wilt. The relative humidity of air is preferably 50% to 60%.
3. Soil requirements Soils with high topography and dryness, good drainage, convenient irrigation, deep soil, loose and fertile soil are not suitable for planting in low-lying land, and cannot be used in conjunction with solanaceous crops.
4. Requirements for Fertilizer For every 1,000 kilograms of fresh fruit produced, the ratio of consumed nitrogen, phosphorus pentoxide and potassium oxide is 1:0.2:1.4, which is a good potassium crop.
Third, cultivation measures
1. Seedbed preparation Apply 1 kg compound fertilizer or 1 kg of potassium dihydrogen phosphate per cubic meter of nursery soil. The ratio of farmyard fertilizer and nursery soil formula is 1:3. About 200 grams of fungicide such as carbendazim, chlorothalonil or thiophanate-methyl, and 200 grams of trichlorfon or insecticide should be added per cubic meter of nursery soil. . Mixed soil heap stuffy for more than 1 week standby.
2. The seed preparation is soaked with a 1% concentration of copper sulfate solution for 5 minutes before sowing, and then rinsed with clean water to prevent chili diseases such as anthracnose, scab and disease.
3. Seed soaking the seedbed with water, when watering, add appropriate amount of potassium permanganate to the water, disinfect the nursery soil, spread a layer of dry nursery soil on the surface of the seedbed after water infiltration, then sow the cover soil, the thickness is about 1cm The temperature is maintained above 15°C.
4. Miao seedlings from 3 to 5 cm, usually in the afternoon after the sunny seedlings, watering between the seedlings and then cover the soil to prevent the seedbed surface hardening.
5. Seedlings
After 5 to 6 true leaves, the seedlings were started.
Fourth, Daejeon transplantation colonization density: spacing 50 ~ 60 cm, spacing 15 to 20 cm. Planting methods: 1 flat land colonization; 2 open trench planting, ditch depth 5 cm; 3 ridge ditch planting, ditch depth of 15 to 20 cm. Before planting, soil can be sealed with 80 to 100 ml of Jindal or 150 to 200 ml of Xiner.
V. Field management The temperature of the seedling stage after transplanting is maintained at 25-32°C, and the temperature during the flowering period and the result period should be maintained at 15°C or more, and the minimum temperature during winter seedlings should not be lower than 5°C.
After the seedlings were transplanted, the water was slowly poured twice. After easing the seedlings, combine with nitrogen fertilizer and pour water once more. Flowering fruiting period does not water. As a result, water is always diligently applied and water is poured to keep the floor moist. Usually, nitrogen fertilizer is applied one time after the seedlings are slowly growing, and fertilizer is applied once every 10 to 15 days in the result period, and urea, potassium dihydrogen phosphate, compound fertilizer and organic fertilizer are alternately applied.
Sixth, the harvest and drying fruit can be harvested after all the colored dark red. When the harvest is generally used to pull out or cut the rake, with the harvest on the spot to spread the sun 3 to 4 days, so that the stem leaves in the water loss of 50% to 70%, pepper fruit water loss of 5% to 10%, some of the pepper off Most of the leaves dehydrated and shrunk, moved to a well-ventilated place without sunlight, and piled high to dry. The stack height should not exceed 60 cm; or bundling and drying, every 4 to 8 strains should be bundled at the base, and 2 to 3 bundles should be placed on or hung on In a non-polluting, ventilated environment, air for another 15 to 25 days. When you shake your hand, you can pick fruits.
