The fog weather often occurs in winter. In this weather, the sunlight in the greenhouse is less than 1/5 of that in sunny days, the relative humidity in the air is above 95%, and the indoor temperature is below 15°C. Such bad weather not only limits the photosynthesis of strawberry leaves, reduces photosynthetic products, and delays ripening of strawberries. For example, a few days of foggy days during the flowering period of strawberries will greatly reduce the fruit setting rate of strawberries and cause malformed fruit, leading to a decline in yield. Poor quality. Management measures: First, increase artificial auxiliary lighting. An incandescent lamp can be used as a light source for heat treatment. Each 100 watt lamp is about 7.5 square meters. Every day from 5 to 10 pm, it is heated for 5 to 6 hours. Strawberry can increase production by 30% to 50%, and deformed fruit can be reduced by 50%. The second is a reasonable temperature control. Temporary heating equipment is installed, heating is generally performed at night, and ventilation is performed for short periods of time before and after noon. The daytime temperature in the control booth is about 20°C and the nighttime temperature is above 10°C. The third is auxiliary pollination. During the strawberry flowering period, the stocking bees assist in pollination, and pollination by the bees can increase the fruit setting rate by 50% to 70%.
UniChiral® is a family of polysaccharide chiral
chromatography media based on NanoMicro`s unique silica matrix with monodispersed particle size and large pore
morphology. This product line includes
CND, CNJ, CNZ, CMS, and CMD five series that employ Cellulose and Amylose
respectively as surface coating for the derivatization of varied chiral selector phases. They
provide a variety of complementary selectivity that allow you to screen for the
most effective chiral separation and purification. While the 5 µm and 10 µm are
routine catalogue offering, other particle sizes can be customized upon
request. Besides UniChiral® bulk media, NanoMicro also offers their HPLC columns for
analytical and semi-preparative purification applications. UniChiral® products are very affordable and highly
competitive in quality and performance.
They will make your chiral separation experience easy and productive.
