1. Temperature and light adjustment The dying of the primordia and young buds is mainly affected by dry and direct light, so attention must be paid to temperature and light management. When the primordium differentiates into buds and buds grow to a size of 2 to 3 cm, the air humidity in the greenhouse should be prevented from drastically decreasing (below 60%), direct sunlight should be prevented from reaching the young mushrooms, and the humidity should be kept between 85% and 90%. 3:7, keep the best temperature conditions for the growth of young mushrooms, to cultivate large mushrooms and round the whole mushroom, lay the foundation for the growth of mushroom into mushroom. 2. Moisture regulation caused a large number of mushrooms, the main reason is the 1.0 ~ 1.5 cm small mushroom mushroom bar lack of water (ie, bacteria bar moisture content below 50%), air drying, mushroom cell suspension Caused by growth. Therefore, care must be taken to prevent the greenhouse from being too dry and the fungus rods losing too much water. In these two situations, it is necessary to reduce the number of ventilation in the greenhouse, maintain the humidity, or maintain the air humidity at 60% to 70% through spraying. If there is a large area of ​​damaged bags, subsidies must be provided in time to reduce water loss. In addition, when the young mushroom is 2 to 3 cm long, it is necessary to neglect the bud, reduce nutrient consumption, and keep 3 to 5 large mushroom and thick mushroom for each rod to form mushroom to reduce the occurrence of mushroom budding. 3. To prevent excessive environmental humidity The cause of Camellia oleifera is mainly caused by excessive relative humidity in the air. In this case, the humidity in the greenhouse must be strictly controlled. We must pay close attention to the weather forecast. In case of rainy weather, we should use various means to keep the air dry. In a closed greenhouse, dehumidifiers can be used for dehumidification, or hot air can be used to blow hot dry air, or some water-absorbing agent can be sprinkled in various positions in the shed. 4. To master the maturity of young mushrooms to reduce the opening of the mushroom, the main measure is to timely master the maturity of the young mushroom, that is, when the young mushroom grows to 2 to 3 centimeters in length, it should be immediately processed to promote the formation of mushroom. At the same time to prevent sudden high temperature effects. Because of the higher temperature, young mushrooms grow faster and easier to open. Before the high temperature comes, it is necessary to cool down in time to ensure the formation of thick flowers under low temperature conditions.
romatographic and use double-antibodyromatographic and use double-antibodysandwich method to detect antigen. Whenthe concentration of antigen in specimen ishigher than the minimum detection limit, theviral antigen will form complexes withlabeled antibodies first. Under chromatogra-phy, the complexes move forward along thenitrocellulose membrane till captured bypre-coated monoclonal antibody ofindetection zone.Through the visible color tointerprete the test results.
