In the middle and late stages of sweet potato, focus on this "three defenses"

Anti-harm

Most areas are rainy, the stems and leaves of sweet potato plants grow rapidly, and the nutrients do not go upwards. At this time, attention should be paid to drainage, that is, the water in the area should be quickly removed after the rain, and the upper part of the ground should be controlled to make the potato pieces not wet. The soil is rapidly expanding.

Defense chief

In the hot and rainy season, the soil moisture is too large, and some sweet potato varieties are rooted too much, especially in the high-fertilizer plot, the sweet potato white roots are much deeper and deeper. It can control the stems and leaves, and can dry the ridges and improve soil permeability. However, during this period, it is impossible to turn over the vines, because the vines are easy to damage the stems and leaves, disturbing the even distribution of the leaves, affecting the photosynthesis efficiency of the leaves, resulting in reduced yield. It is also possible to spray paclobutrazol several times. For the long sweet potato field, 15% paclobutrazol 50-70 g per acre is sprayed on 50 kg of water, and generally sprayed 3 times, the effect is better.

Premature aging

In the middle and late stages of sweet potato growth, attention should be paid to foliar fertilizer such as potassium dihydrogen phosphate. Because potassium fertilizer can not only prolong leaf age, but also improve photosynthetic efficiency, promote the operation of photosynthetic substances, and promote the rapid expansion of potato chips. 100 grams of potassium dihydrogen phosphate, 50 kg of foliar spray with water, 3 times a week.

Digestive Tract Disease Tests

Digestive diseases are disorders of the digestive tract, which is sometimes called the gastrointestinal (GI) tract.
In digestion, food and drink are broken down into small parts (called nutrients) that the body can absorb and use as energy and building blocks for cells.
The digestive tract is made up of the esophagus (food tube), stomach, large and small intestines, liver, pancreas, and the gallbladder.
A digestive disease is any health problem that occurs in the digestive tract. Conditions may range from mild to serious. Some common problems include heartburn, cancer, irritable bowel syndrome, and lactose intolerance.

it include the Salmonella Typhi IgG&IgM, H.Pylori antibody test, H.Pylori antigen test, Rotavirus antigen test, Adenovirus antigen test.


1. Using internal quality control samples:
Negative specificity: The results should all be negative when detecting 10 kits of HP negative quality
control samples.
Positive specificity: The results should all be positive when detecting 10 kits of HP positive quality
control samples.( Including strong, medium and weak positive samples)
Limit of detection: The results should all be positive when detecting diluted HP positive quality control
samples with the diluent rate at 1:8.
Repeatability: The results should be consistent and the coloration degree should be consistent when
detecting the precision control samples by 10 kits of the same batch.
2. Clinical trial results
A clinical evaluation was conducted on 1050 samples comparing the results obtained using the
Helicobacter Pylori Antibody Rapid Test Kit (Colloidal Gold) and other commercially available HP tests.
