Occurrence and Prevention Technology of Sweet Pepper

Sweet pepper day burn disease is a kind of common physiological disease in the production of sweet pepper. The disease mainly occurs on the sunny side of the fruit, and it is sun gray or light white leathery in the early stage of the disease. The surface of the diseased part is thin and the tissue is necrotic. Hard; later saprophytic infection, grow gray moldy layer and rot.
Causes of the disease: Before the high temperature season, the plants did not fully grow and the leaves were not well shaded. Excessive dry soil or excessive dry weather and exposure to sunlight can all lead to the disease.

Prevention and control measures: 1 Planting at a proper time, close-up and planting in a reasonable manner, using double plants per hole to make the leaves shade each other to prevent the fruits from being exposed to sunlight. 2 timely watering after planting, with ammonium per acre to recover 15-20? Ammonium; to promote flourishing. 3 After fruit set, the leaves were sprayed with 1% superphosphate and sprayed once every 5-7 days for 2-3 consecutive times to improve the anti-jamming ability. We must promptly prevent and control pests and diseases and avoid early defoliation.

Cryopreservation Tube

The cryovial is made of medical polypropylene (PP) and is a disposable laboratory consumable specially used for storing biological samples. In the gaseous state of liquid nitrogen, it can withstand low temperature to
minus 187°C. The unique external rotation design avoids the possibility of cross-contamination. Silicone gasket inside the cap to avoid liquid leakage and ensure tightness even at cryogenic storage temperatures

The sealing property finally ensures the safety of the samples in the tube. Caps come with a variety of embeddable color codes for easy identification.
