1. Protect the land preparation. The whole land is premised on drought-resistance and protection, and the plots with bad lyrics should be as little as possible to move the soil or not move the soil, and the plots that fall through the ridges in the autumn will be timely suppressed and protected in the early spring; Top ridges, topping ridges and ridges; heavy glutinous corn must be rotted in spring, and immediately after the ridge ridges are repressed to reach the state to be sown; there is a soybean hoe that deepens the deep pine foundation, after freezing in the early spring, The original ridge machine broadcasts corn, and the seedling stage is deep and loose.
2. Choose the variety. In the first accumulated temperature zone, the active accumulated temperature is above 2700 °C, and the main push varieties are Xingyu 3, Jidan 517, Jiangdan 1, Erqidi and Hetao, which are mainly Jidan 27. The second accumulated temperature zone has an active accumulated temperature of 2500-2600 °C or above. The main push varieties are Jidan 27, Sidan 19, Nen Shan 12, Fenghe 3, and Jidan 522. The third accumulated temperature zone has an accumulated temperature of 2400-2500 °C. The main push varieties are Jidan 27, Longdan 32, Longyu 4, Yudan 10, and Saitama 15. The purity of the selected seeds is not less than 95%, the clarity is not less than 98%, the germination rate is not less than 90%, and the water content is not higher than 16%. Sun-breeding and germination tests before sowing.
3. Seed treatment. In the case of serious pests in the underground pests, seed coating should be done in strict accordance with the instructions for the use of corn seed coating agents. Corn germination seeds cannot be coated to prevent phytotoxicity. The plot of corn smut is a 2% lyche seed dressing. The germination is carried out by the water and the land is planted. After the corn seeds are germinated, they are cool for 6-8 hours, and then 2% of the ricketts are used for seed dressing at 0.3% of the seed amount. Conditional farmers can choose to use the drought-resistant seed coating agent for seed dressing.
4. Balance fertilization. The soil testing formula fertilization is carried out, and 22.5-30 cubic meters of high-quality agricultural fertilizer per hectare is used as the base fertilizer. When planting, use 225-300 kg of corn formula fertilizer per hectare for seed fertilizer. It can also be used as seed fertilizer with diammonium phosphate 112.5-150 kg + urea 75 kg + potassium sulfate 75 kg + zinc sulphate 15 kg per hectare, using chemical fertilizer deep application technology to achieve seed and fertilizer isolation and prevent burning buds.
5, drought-resistant sowing. The first is to rush to sow. Generally, the southern towns and towns are planted from April 25th to May 1st; the northern townships are planted from May 1st to May 5th. The second is to use germination or germination to sit on the water. Land parcels with a water content of less than 20% should be waterlogged or mechanically filtered. It is necessary to sit in sufficient water and suppress it every other day. In the germination of live land, the germination seeds should be planted in the wet soil, and the depth should be strictly controlled to ensure that the soil is tightly covered and timely suppressed.
6, to ensure density. The seeding amount should be determined according to the characteristics of the variety, the condition of the land preparation, the sowing method, and the number of seedlings to be kept. Generally, the amount of sowing per hectare is 33-37.5 kilograms, and the amount of artificial tillage is about 30 kilograms per hectare. Plant-type astringent varieties are protected from 5.1 to 55,000 plants per hectare; plant-type luxuriant varieties are protected from 4.5 to 500,000 plants per hectare. In order to ensure a reasonable planting density, sufficient seedlings should be kept at the time of sowing for replanting.

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.
