Planting autumn peppers in greenhouses can be delayed until New Year's Day and Spring Festival. The technical details of its field tube are briefly described below. Temperature adjustment. The first is the slow seedling period. Generally in late September, 5 days to 7 days after planting, the greenhouse was warmed and seedlings were planted. The daily temperature in the shed was maintained at 30°C-35°C and 13°C at night. The second was the result before. After the seedlings should be properly ventilated, so that the shelf temperature is maintained at 28 °C -30 °C, higher than 30 °C should be ventilated to cool, stop the ventilation below 25 °C; the third is the result period. After the beginning of October, when the temperature drops below 10°C during the night, small sheds should be placed in the shed; after mid-November, in order to prevent freezing damage, the grass should be covered with a straw shed at night to keep the night temperature no lower than 15°C. °C, during the day generally maintain a suitable temperature of 20 °C -25 °C; four is a severe winter period. Generally in the cold winter after mid-December, should be closed shed insulation, grass tarpaulin to early exposing the early cover, so that the temperature within the small arch shed during the day at 22 °C -27 °C, night at 13 °C above. Adjust fertilizer control water. During the flowering period, 3 times - 4 times of cultivating loose soil bacon, cultivating depth 6cm, total earthing height 12cm, and less watering or watering; after the peppers and peppers are harvested, pour water and apply fertilizer once. , Apply 15 kg of ammonium sulfate per acre, 15 mg of superphosphate, 150 kg of bio-potassium fertilizer (or 60 kg of plant ash) per acre, and apply a deep hole or planting effect between the plants with good results; after harvesting in Simen Dou, eight-faced wind, and full days of the week, The water should be fertilized 4 times, and the amount of fertilizer should be gradually increased. Generally, the first-time compound fertilizer (nitrogen, phosphorus and potassium ratio is 15:15:15) is used for the first time; 10kg; the second and third are respectively 15kg; The fourth application does not exceed 20kg. Plant adjustments. After the door pepper is sitting, the following lateral branches should be promptly blown and erased, and the diseased leaves and old leaves in the lower part of the plant should be frequently removed; after the harvest of the four-door dougong, to prevent the plants from lodging, it is easy to ventilate and transmit light and field. The operation should be framed and fixed; after the spring, if the rejuvenating plant is updated, the branches above the four-door bucket should be left with two sections cut off, and the top-dressing watering, the new branch growth and flowering and fruit setting should be promoted. Falling and falling fruit temperature is lower or a larger temperature change can cause autumn delay capsicum drop and drop; should be 30PMM chili pepper or tomato seedling before and after 10 o'clock in the sunny day before and after flowering. Disease prevention and pest control. The main diseases of autumn pepper in greenhouses are epidemics, gray mold, virus diseases, etc., which can be used 50% fluocin 1000 times, 50% fast gram 1500 times, 20% phytobiotic II 800 times, after the live tree Every 10 days to 15 days, alternating spray control 4 times -6 times; insect pests are tea scutellariae and aphids, etc., can be controlled by 800-1000 times of dicofol and enemy kill. Harvest timely. When the outside temperature is too low and the peppers in the greenhouse cannot continue to grow, they should be harvested in time to prevent the fruits from freezing, resulting in cracked fruit or berries, etc. They can also be listed in batches or harvested on New Year's Day or Spring Festival in accordance with market conditions. market.
API
what is API?
High-purity plant monomer refers to one or more single chemical components with specific biological activity or pharmacological effects extracted from plants, and its purity is usually high, meaning that the content of the component in the extract reaches a certain percentage, and the content of other impurities or irrelevant components is low.
These plant monomers are usually secondary metabolites of plants, such as flavonoids (flavonoids), alkaloids (alkaloids), terpenoids (terpenoids), phenolics (phenolics), etc., which play a variety of physiological functions in plants such as defense, signal transduction, and antioxidant. Due to their pharmacological activity, high-purity plant monomers are often used in pharmaceuticals, health products, cosmetics and other biotechnology products.
For example, Naringenin is a high-purity plant monomer extracted from citrus plants with antioxidant and anti-inflammatory activities; Corosolic acid is a high-purity active monomer extracted from loquat leaves, which is considered to be effective in treating type 2 diabetes and obesity.
Extraction and preparation of high-purity plant monomers usually require a complex separation and purification process, including extraction, column chromatography, crystallization, recrystallization and other steps to ensure the purity and activity of the final product. These processes may be required by specialized biotechnology companies.
