Lienless sunshine affects the photosynthesis of fruits and vegetables in the facility, reduces the yield and quality of fruits and vegetables during the fruiting period, reduces the disease resistance of the plants, and induces diseases such as gray mold and downy mildew; windy weather threatens the safety of the greenhouse facilities. Causes damage to the film and causes freezing damage. In view of the impact of the recent weather on the fruits and vegetables in the facility, measures should be taken immediately before the arrival of snowfall and cold wave weather to do a good job of “windproof, thermal insulation, antifreeze, and increased lighting in the shedâ€. 1 pay attention to insulation, appropriate heating. Can be covered with multiple layers of insulation, that is, covered with a double layer of straw grass outside the film; In addition, frost damage occurs in the front of the greenhouse, in front of the greenhouse can be covered with haystacks. If the temperature in the greenhouse is lower than the minimum temperature required by the crop, room temperature can be appropriately increased by auxiliary warming, but the indoor temperature cannot be raised too high to affect normal development. 2. Try to scatter light. In the case of overcast days, as long as the temperature is not very low, the grasshoppers should be properly uncovered and scattered light should be striven for. At the same time, a light curtain can be hung in the back of the greenhouse to add light and warm the effect. 3. The long-term drizzle should be scientifically revealed. If the weather is suddenly clear after continuous snowfall, all coverings cannot be removed and they should be gradually removed to prevent “flashingâ€. After the exposing, we should pay attention to observe crop changes. When wilting occurs, we must immediately cover the grass weeds. After the recovery of the seedlings, remove the grass weeds. This repeated two or three days, and then transferred to normal management. 4. Make plant adjustments and protect the plants. According to the weather forecast, before picking snow days, fruits should be picked early to reduce the nutrient consumption of plants, return nutrients to the root system, promote root growth, and enhance the ability of plants to resist adverse environments. 5. Before the arrival of snowfall weather, plastic rain-snow film can be placed on the straw to keep the grasshopper dry. After the snow stopped, remove the snow immediately to prevent melting of the snow and ensure that the cover is dry to facilitate insulation. 6. Stop watering fertilizer and pay attention to disease prevention and control. Even in the cloudy greenhouse, watering fertilizer should be stopped, so as not to cause root crops and aggravate the occurrence of diseases. 7. Pay attention to wind protection. Before the arrival of windy weather, check the fixed condition of the plastic film, the film line or the pressure rod must be fixed firmly, and cover the grass beard tightly, the damaged film must be repaired.
NanoMicro offers wide selection of reversed phase
silica chromatography media based on monodisperse UniSil® matrices. Besides varied bonding phases, different
surface modification of UniSil® matrices were employed to provide varied
category of RPC silica media products.
For example, UniSil® Ultra and UniSil® Ultra Plus are two categories of
products for higher pH tolerance. While UniSil® matrices` work pH range is up to 8, UniSil® Ultra and UniSil® Ultra Plus products can extend their
work pH range up to 10 and 12 respectively, significantly increasing the
lifetime of their performance. The
following table summarizes the offering of all NanoMicro`s reversed phase silica products.
