Summer cabbage is a kind of Chinese cabbage cultivated in summer, and it is a seasonal dish to fill the consumption of urban and rural residents in summer and autumn, such as hot pot and bottom dish. “Hundred dishes are not as good as cabbageâ€, and the nutritional value ranks first among the 100 dishes. However, its whole growth period is in high temperature and rainy or drought stress, and there are special measures for cultivation and autumn cabbage. In recent years, with the continuous improvement of seed production and cultivation techniques of domestic cabbages at home and abroad, farmers' friends have basically reached the goal of planting Chinese cabbage in time, and harvesting in batches in batches, which enriched the selection and cultivation. The vegetable baskets of urban residents have improved their economic benefits. To this end, summer cabbage should pay attention to the management of fertilization:
The specific method is to strictly select the cultivated plots, apply the base fertilizer, and cultivate with high ridges. In order to control or alleviate the occurrence and damage of diseases and insect pests in cabbage in summer, we should choose a land with high dryness, good drainage and irrigation conditions, and loose and fertile soil. It is best to gargle with garlic, onion and other crops. To avoid or reduce the spread and harm of viral diseases. At the same time, it should avoid neighboring or pre-pigmented with vegetable crops such as watermelon fields and tomatoes. Because summer cabbage has a short growth period and fast growth, it must also pay attention to the application of decomposed organic fertilizer to improve soil permeability and fertilizer retention.
Fertilizer and water promote early, timely harvest, in order to achieve high yield and high efficiency, should be balanced with fertilizer and water, one to promote the end, not slow seedlings. Topdressing should be repeated a small number of times. Generally, some fertilizers are applied during the seedling stage and after the seedlings are applied. In the rosette stage and the beginning of the ball, the amount of bio-organic fertilizer and high-nitrogen compound fertilizer should be applied to both sides of the ditch, and appropriate ridges should be planted and watered for 1 or 2 times. Harvesting can be carried out in batches, and plants with good balling can be harvested.

Diagnostic reagents can be divided into two categories: in vivo diagnostic reagents and in vitro diagnostic reagents. It is mostly a reagent for detection by the reaction between antigen and antibody.
A: Classification of in vitro diagnostic reagents:
1. In vitro biodiagnostic reagents managed as drugs include:
1. Blood type and tissue type reagents;
2. Microbial antigen, antibody and nucleic acid detection reagents;
3. Tumor marker reagents;
4. Immunohistochemistry and human tissue cell reagents;
5. Human genetic testing reagents;
6. Biochips;
7. Allergy diagnostic reagents.
2. In vitro reagents managed as medical devices include:
1. Clinical basic test reagents;
2. Clinical chemistry reagents;
3. Blood gas and electrolyte determination reagents;
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.
