Every year after entering the year of July, different levels of flooding will occur at different times throughout the country. Then, how should the rose cut flowers be managed after the flood? Post-flood climate characteristics The temperature in the shed is relatively high, and the temperature difference between day and night is larger in the central Yunnan area. After the flood, if the greenhouse has a plastic canopy with a shoulder height of 2 meters and a ceiling height of 3.50 meters, the temperature in the shed is between 28 and 42 degrees Celsius at noon. If in a plastic canopy with a shoulder height of 1.50 meters and a ceiling height of 2.50 meters, the temperature is between 35 and 48 degrees Celsius. At night, the interior temperature of the above specifications is only between 15 and 17 degrees Celsius. In the plastic greenhouse after the heavy air humidity in the shelter, the relative humidity in the clear day is 60%-70%, and the humidity in the night is more than 80%-90%. Rose after the flood 1. Mud covers the foliage. 2. Sprout shoots, wilting or rot on sunny days, mature branches or fallen shoots. 3. The petals are rot and the rot is doubled. Rose Field Management after the Flood 1. Discharge the stagnant water as soon as possible, timely loosen the topsoil, remove the toxic gases produced by the roots under anaerobic respiration, reduce the root damage, and restore the normal absorption capacity of the root system. 2. Remove damaged flower branches and leaves in time. After the flood, what pressure loss, blistering, and rushing branches and leaves must be sorted out in time, and then widely used fungicides such as carbendazim, chlorothalonil, metalaxyl, etc. should be sprayed. 3. Wash the sludge on the leaves in time to restore the photosynthetic capacity of the leaves. On the leaves, KPS, carbendazim, metalaxyl, etc. are sprayed to protect the affected foliage from falling leaves or leaves. 4. Shading ventilation to reduce the physiological damage caused by high temperature and humidity during the day. Cover the roof with a shade net of 30% to 50%, and open or roll up the side membrane of the greenhouse to promote ventilation and cooling. Make greenhouse temperature below 28 degrees. 5. Early prevention of downy mildew and gray mold. After the flood, due to the increase of air humidity in the shed, the night temperature dropped to 15 degrees to 18 degrees, creating conditions for the occurrence of rose gray mold, downy mildew, resulting in large deciduous rose plants, rotten and burnt phenomenon. The main pesticides for the prevention of rose downy mildew and gray mold include Kelu, Ank manganese zinc, fast keratin, Shijiale, and Rhizoctonia. Isolation clothes, also known as clean work clothes, clean work clothes, purification clothes, dust-free clothes, sterile clothes, anti-static work clothes, dust-free work clothes, work clothes, protective clothes, etc. Disposable Isolation Clothing,Disposable Isolation Gown,Disposable Medical Isolation Gown,Disposable Hospital Isolation Gown Guangzhou Aikangli Medical Technology Co., Ltd. , https://www.aikanli.com
In addition to the fact that clothing itself cannot be a source of dust emission, it also has the effect of preventing dust from being emitted by the human body. At the same time, as a sterile clothing, it should have basic properties such as safety protection, comfort, ease of operation, aesthetics, etc. in materials and design. Otherwise, due to the different styles, fabrics and sterile underwear of the work clothes, it directly affects the number of dust and colonies in the clean room.
Widely used in electronic, pharmaceutical, food, biological engineering, optics, aerospace, aviation, color tube, semiconductor, precision machinery, plastics, paint spray, hospitals, environmental protection and other industry clean workshops, there are a variety of colors and specifications suitable for different anti-static Or clean environment.

100% high-density polyethylene material, one-piece hooded design, breathable and moisture-permeable, can block the penetration of fine dust and liquids, and at the same time allow water vapor to permeate; light and tough, prevent the accumulation of static electricity, it does not produce dust , Free of silicon.
It is made of special polyester filament, warp or warp and weft inlaid with Japanese bell spinning 9R series conductive fiber, and manufactured by a special process. Has excellent, long-lasting conductivity. It is a necessary measure for anti-static of personnel clothing.
The charge of work clothes: <0.6 micro library / piece. Charge area density: <7 microbanks / square meter.
(Annotation of "micro-coulomb": "coulomb" is a unit of charge measurement, 1 coulomb = 1000 milli-coulomb = 1,000,000 micro-coulomb. 6.25 × 108 electrons carry 1 coulomb, and the power of one electron belt is 1.6 × 10 19 coulombs).
* Fabric editing
The fabrics used are: fabrics containing conductive silk, gabardine, yarn cards, TYVEK (acid and alkali resistance), etc.
Conventional optional fabrics: 5mm strip type, 5mm mesh, 2.5mm mesh fabric conductive silk, its anti-dust and anti-static effect is getting stronger and stronger in order; this is also selected according to the clean room level, generally CLASS10000 The clean room below (ten thousand area) should use 5mm strip conductive silk, CLASS1000 (thousand level area) and 5mm grid should be used; CLASS100 (100 level area) clean room should use 2.5mm grid fabric conductive silk.
Isolation clothing fabric-like characteristics
1. Japanese original parallel wire processing technology, with excellent anti-static performance, is permanent and can effectively discharge human body electrostatic charge;
2. The clothing itself is not dusty, non-sticky, has good barrier properties, high density, high strength, can effectively sterilize, and inhibit bacteria
3. Good washing resistance, bending resistance, abrasion resistance, etc., washing resistance ≥100 times, high temperature steam temperature: 120 ℃;
4. All-over-seaming process of special equipment imported from Japan, one-time forming, good dust resistance, can be used in 10-10 thousand grade clean room;
5. Especially recommend the production and sales of breathable anti-static clean clothes.
* Advantage edit
1. The fabric itself does not produce dust: because it is worn in a clean room, the fabric must not be a source of dust in the clean room, which determines that ultra-clean fabrics can only be produced with chemically synthesized long fibers. Natural short fibers such as cotton, hemp, and silk cannot be applied to ultra-clean fabrics, although these raw materials can make the fabrics more wearable. At the same time, it is required that the selected chemical fiber filaments also strictly control the amount of dust generated. Generally speaking, fully matt polyester filament is not suitable for weaving anti-static ultra-clean fabrics. Because the matting agent added in the production of polyester-titanium dioxide will become a source of pollution.
2. The fabric should have good dust filter: the dust in the clean room mainly comes from the air flowing in the room and the human body moving in the room. When the equipment conditions are determined, improving the cleanliness means that the fine dust generated by the human body should be controlled in the clothes to the maximum, and let it pass through the fabric and enter the air. This is the so-called fabric filter rate is higher. Increasing the dust filtration rate is at the expense of the breathability of the fabric, so knitted fabrics and woven fabrics that are more loosely woven are not suitable for clean rooms.
