One is to choose a drop-free film. The use of a non-drip film can reduce the amount of water accumulated on the surface of the film, and is conducive to light transmission and temperature increase in the shed. The second is to cover the mulch. Since the mulch film is not permeable, the amount of surface water evaporation and irrigation can be reduced, thereby achieving the purpose of reducing the humidity of the air in the shed. The third is reasonable watering. Watering the shed in winter, you need to do “five pouring and no pouringâ€, that is, watering on sunny days, not watering on cloudy days; watering before noon, no watering in the afternoon; pouring small water, not flooding; pouring warm water, not Pour cold water; pour dark water, do not pour water. The fourth is to improve the application method. In the winter, the vegetable pests and diseases in the greenhouse should be used as much as possible by the smoke method or the dust method. If the spray method is applied, the number of prevention and the amount of liquid spray should be appropriately reduced to prevent the humidity in the greenhouse from being too high and affect the growth of vegetables. The fifth is artificial moisture absorption. If the humidity in the shed is too large, you can sprinkle some straw, grass ash or fine dry soil between the rows. You can also absorb hygroscopic materials such as quicklime in the free space of the shed to absorb moisture. Disclaimer: Some articles on this website are transferred from the Internet.

7. Microbiological test reagents.
B: According to medical test items, clinical diagnostic reagents can be roughly divided into clinical chemical test reagents, immunology and
Serological testing reagents, hematological and cytogenetic testing reagents, microbiological testing reagents, body fluid excretion
Detection reagents, genetic diagnosis reagents, etc. Among them, the market share of clinical chemistry
The largest, close to 34%; followed by the immunology market, accounting for about 29%. Novel immunodiagnostic reagents and genetic diagnostic tests
The reagent was developed in the late 1980s, and it is the most common diagnostic reagent for all current diagnostic reagents, regardless of technology or market.
