Although it has been in the autumn for several days, the temperature in the greenhouse remains at a high level. Many vegetable farmers have reported that the vegetables in the greenhouse have recently suffered from unpleasant phenomena such as leaf scorch, curled leaves, and water loss at the leaves, which seriously affected the normal growth of the plants. In response, Zhuang Canyan, a vegetable expert at the Northwest Agriculture and Forestry University, suggested that greenhouse vegetable management should be strengthened in the following areas in the near future. Ventilation shed air does not circulate, it is easy to cause vegetable plants lose water wilting, growth disorders, etc., vegetable growers should do a good job ventilation and cooling shelter work, open the shed door on a sunny day and night, the shed on both sides of the film rolled up to the shed, Increase ventilation. Watering to take a small water pouring, the application of micro-drop micro-spray technology, can effectively reduce the impact of drought on vegetable production, anti-disaster preservation; can save labor, labor, water, reduce labor intensity; but also humidification, cooling, improve The microclimate in the field regulates the status of soil water, fertilizer, gas, and heat, and promotes the growth of vegetables, so that the commercial nature of leaf vegetables in summer and autumn is greatly improved. Spraying foliar fertilizer leaves spraying 100% of 27% high-fat film emulsion, 1500 times of Apollo 963 chitin, Tianda 2116, amino acid, fulvic acid foliar fertilizer, etc., can form a protective film on the surface of leaves and improve the vegetables in the greenhouse. High temperature and strong light resistance. Zhuang Chanran reminded farmers that under high temperature conditions in the shed, they must pay attention to safe production when they are engaged in vegetable management. First, when hot weather occurs, try not to enter the shed. The second is to reduce the temperature first and then enter the shed; Third, continuous operation time is not easy. If it is too long, if there is any discomfort, it shall be immediately released from the greenhouse; Fourth, pesticides should be correctly selected and used to prevent and treat pests and diseases, and high-toxicity, high-residue pesticides should be disabled. At the same time, safe operation should be conducted to prevent pesticide poisoning accidents. Multiplex RT-PCR Test Reagent Kit Of COVID-19(ORF1ab)/Influenza A/Influenza B The Multiplex RT-PCR Test Reagent Kit Of COVID-19(ORF1ab)/Influenza A/Influenza B is a real-time reverse-transcription polymerase chain reaction (RT-PCR) test reagent that detects and differentiates RNA from SARS-CoV-2, influenza A virus, and influenza B virus in upper or lower respiratory specimens. The assay provides a sensitive, nucleic-acid-based diagnostic tool for evaluation of specimens from patients in the acute phase of infection.
