1. Seedlings can emerge 4 to 5 days after sowing, and seedlings should be introduced by breaking the membranes in batches after emergence. About 20 days after sowing, the fleshy roots of radish began to swell. At this time, mud should be used to press the break of the film to prevent the film from being pushed up. 2. The suitable temperature for the growth of radish is above 12℃. The management in the early stage of growth should be based on heat preservation, and the temperature in the shed should be increased appropriately to promote the growth of rosette leaves. In case of strong cold air, it should be covered with cold protection. When the temperature rises in the late growth period, ventilation and cooling should be timely. The temperature in the shed should be controlled at 20℃～25℃ during the day, and the temperature in the shed should be controlled at about 15℃ at night. After mid-April, the shed film can be removed for open field cultivation. 3. The radish does not need to be watered during the growth process, only watering properly when the soil in the furrow is white. The water demand of radishes during the expansion period of fleshy roots is relatively large, which can be irrigated according to the soil moisture content, and drip irrigation is used first. If furrow irrigation is used, it should be carried out at noon on a sunny day. Irrigate half furrow water and drain it 2 hours after irrigation. 4. The first top dressing is done 30 days after sowing and the second top dressing is done around 45 days. If the soil moisture is high, it can be applied in a hole 10 cm away from the root of the radish. 5. Pest control. The pests are mainly aphids and cabbage caterpillars, and the diseases are mainly downy mildew and black rot. The pests should be controlled in time. 6. Harvest in time. When the fleshy roots are more than 5 cm in diameter and weigh about 0.5 kg, they can be harvested in batches. When harvesting, the petioles are left 3 to 5 cm and cut off, and they are cleaned and listed. Disclaimer: Some articles on this website are transferred from the Internet.

4. Vitamin determination reagents;
5. Cell histochemical stains;
6. Autoimmune diagnostic reagents;
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.
