First, soaking seeds. The dried seeds are immersed in warm water of 55 ° C ~ 60 ° C for 15 minutes, and continuously stirred, and then soaked in water at 28 ° C - 30 ° C for about 6 hours. Second, germination. Wrap the soaked seeds in a damp cloth. The temperature is kept at 25 ° C - 30 ° C during the day and 18 ° C - 20 ° C during the night. 80 % of the seeds are white and then planted on sunny days. In order to ensure that the seeds do not carry pathogens, they can also be treated with chemicals. Seeding with new high-fat membrane before planting can keep warm, moisturize and swell, improve seed germination rate and make seedlings strong. Repel underground pests and isolate viral infections. It can also be mixed with a seed coating. Third, nursery nutrition soil preparation. The principle of nutrient soil selection is: good gas permeability, heat preservation, moisturizing, water seepage, the ratio of substrate to organic fertilizer is 3:2, and the added organic fertilizer should be fully decomposed. In addition, 100 g of 50% carbendazim powder and 1 kg of compound fertilizer were added to each nutrient soil matrix, and uniformly mixed, and placed in a plastic bowl. Fourth, seedling management. Breeding in the greenhouse, the indoor temperature during the day before emergence is maintained at 28 ° C - 32 ° C, at night 17 ° C - 20 ° C. In order to prevent the occurrence of diseases, after the emergence of the seedlings, roots were applied with 72.2% Plex water 700 times solution to fill the roots. The seedlings were carried out 7 days before planting. Disclaimer: Some articles on this website are transferred from the Internet.

Doctors suspect an infection based on the person's symptoms, physical examination results, and risk factors. First, doctors confirm that the person has an infection rather than another type of illness. For example, a person with a cough and difficulty breathing may have pneumonia (a lung infection). However, the person may instead have asthma or heart failure, which are not caused by infection. In such a person, a chest x-ray can help doctors distinguish pneumonia from the other possible disorders.
Once doctors confirm that the person has an infection, they usually need to know which specific microorganism is causing the infection. Many different microorganisms can cause a given infection. For example, pneumonia can be caused by viruses, bacteria, or, rarely, fungi. The treatment is different for each microorganism.
