The first is to choose good breeds. Spring maize should be selected from the fertility period of more than 112 days, with well-developed root system, compact plant type, robust growth, strong resistance, single ear, and large grain type. Before sowing, seeds should be carefully selected to remove small grains, diseased grains and pods. Due to the low temperature at the time of sowing, it will cause slow emergence and poor uniformity. Therefore, it is necessary to dry the seeds for 2-3 days before sowing so as to enhance the seed's ability to absorb water, increase seedling emergence, and improve the uniformity of seedlings.
The second is to promote seed coating. As fresh corn seedlings will attract poisoning insects such as Laodelphax striatellus from wheat and other crops to concentrate, the seedling stage overlaps with the occurrence stage of Laodelphax striatellus, and spring corn is often planted in hilly areas, which facilitates the spread of viral diseases. Therefore, we should pay attention to its prevention and control work. The prevention and control methods are mainly using seed coating, and the corn seed can be coated with a drought-resistant composite seed coating agent. The corn seed coating agent must be used in strict accordance with the instructions for use.
The third is to properly sow. The early sowing of spring corn can easily lead to low-temperature rotten seedlings and the emergence of seedlings is uneven, and sowing late can lead to late grain failure. When the soil surface is 5-10 centimeters deep, the temperature can be sown at 10°C-12°C.
The fourth is to master the planting form and density. The soil fertility plots are usually planted in more than 4,000 plots, and the soil fertility plots with 3500-4000 plots per acre are suitable. The sowing volume is 2-2.5 kilograms. The planting pattern is equal spacing or width and width, and the sowing depth is 4-6 cm.
The fifth is to apply fertilizers rationally. Due to the long growth period and large potential for yield increase of spring maize, it is very important to balance the application of base fertilizer and postpone fertilizer application. In the 600-kilogram per mu corn field, 20 kg of diammonium phosphate, 5 kg of urea, and 15 kg of potassium sulfate are applied per mu. When 10 leaves are unfolded, one-time mu is topped with 20 kg of urea, pay attention to deep ditch application or application with watering to increase fertilizer efficiency.
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.
