Unexpected pollination caused by high temperature or low temperature during flowering. During flowering, when the temperature is higher than 38 degrees or lower than 18 degrees, the male and female cannot normally pollinate and fertilize, forming bald or empty stalks.
Drought weather was encountered during heading. In the big bell period, when the corn needs the most water, the drought affects the normal flowering of the tassel and the extraction of the fringe of the ear. Caused the tasseling advance and the filaments to be delayed. In this case, the vitality of the pollen is weak, which makes the filament easy to wither, resulting in poor fertilization and formation of bald or empty stalks.
Malnutrition. In the differentiation stage, the female and the tassel are malnourished, the photosynthetic area is small, and the accumulation of organic matter is small, which makes the ear dysplasia cause empty stalks; while in the prolonged stage of corn, if the nutrient is too much, the vegetative growth is too high, resulting in weakened reproductive growth. Reducing the nutrient distribution to the ear can also lead to stalks caused by dysplasia of the ear. In the absence of elements such as boron and zinc, the flowers may cause empty stalks or baldness.
Continuous rainy weather. During flowering, if continuous rainy weather is encountered, the light is insufficient, and the pollen swells and ruptures and dies or sticks into a mass, resulting in the formation of bald or empty stalks.
The cultivation density is too large. Due to the high density, the ventilation conditions in the field are poor. In the flowering period, the powder is poor or the malnutrition of the dense plant affects the differentiation of the female and stamen, forming an empty stalk.

The characteristics of POCT devices determine that they can play an important role in primary medical institutions. In order to standardize and strengthen the application of on-site rapid testing in primary medical and health institutions, promote the rational allocation, safe and effective use of POCT in primary medical and health institutions, give full play to its use value, and ensure the healthy development of medical and health services, "On-site Point-of-care Testing (POCT) Primary The Expert Consensus on the Application of Medical and Health Institutions (hereinafter referred to as the "Consensus") came into being. The consensus was published in the 2019 "China Medical Equipment" magazine after first draft writing, 2 expert on-site discussions, 2 expert online review meetings, and 3 submission revisions. The formulation of the consensus will greatly promote the management standards of the POCT industry, continuously increase the training of grass-roots personnel, deeply understand the application requirements of POCT at the grass-roots level, and promote the rapid development of the POCT industry.
Point-of-care testing (POCT) represents a fruitful method in today's hospitals in terms of patient care and cost management. Its application enables some of the testing items originally undertaken by the central laboratory to be transferred to the clinical departments and patient beds that need it. side. For blood gas analysis technology, POCT has shown great advantages.
Our blood gas analyzer is small and portable, beautiful in appearance, accurate in results and good in stability. It is a blood gas analysis platform with both appearance and strength. It can be used not only in the central laboratory department, but also at the bedside of patients to meet the bedside detection needs of clinical departments such as hospital ICU, emergency, anesthesia, respiratory, neurology, etc. It realizes true POCT blood gas analysis and provides more advantageous assistance for clinical practice.
