Spring cabbage has the characteristics of less investment, labor saving and high output in production. The spring season of growing cabbage can receive very good economic benefits. Here are the relevant technical points.
Choose a variety. Early spring cold shed cultivation can use strong cold resistance, strong disease resistance, strong winter varieties. Planting in the open field in the spring can use Zhonggan 15, Zhonggan 21 and other early maturing, high-yield and disease-resistant varieties.
Prepare a seedbed. The nursery bed was mainly fertile, and there was no cultivating field of cruciferous vegetables in the previous year. It was necessary to apply adequately decomposed farmyard manure and appropriate amount of ternary compound fertilizer. Before sowing, 50% of methine WP can be used to completely sterilize the seedbed, and the dosage per square meter is about 10 grams.
Seed management. Before emergence, the greenhouse or Yangshuo temperature to maintain 15 °C ~ 25 °C, generally 5 days after sowing can be Qimiao, this time, pay attention to timely and gradually release the air, so that the temperature is maintained at 10 °C ~ 20 °C, if the seedlings too dense, You need to conduct the seedlings to prevent the seedlings from becoming leggy. When the seedlings grow to three true leaves, a sub-seedling will be carried out. The seedlings will be transplanted into the nutrient bowl, and the temperature of the seedbed is generally controlled at 8°C to 20°C. Before the seedlings are planted, low-temperature seedlings can be prepared. Gradually increase the amount of ventilation, the minimum temperature of the seedbed can be gradually reduced to about 5 °C, hardening time is about a week. Afterwards, they are planted according to their cultivation mode and weather conditions.
RT-PCR Test Reagent Kit Of COVID-19(ORF1ab, N)
The RT-PCR Test Reagent Kit Of COVID-19(ORF1ab, N) is a real-time RT-PCR test intended for the qualitative detection of nucleic acid from the SARS-CoV-2 in upper and lower respiratory specimens (such as anterior nasal swabs, mid-turbinate nasal swabs, nasopharyngeal swabs, oropharyngeal swabs, sputum, lower respiratory tract aspirates, bronchoalveolar lavage, and nasopharyngeal wash/aspirate or nasal aspirate) from individuals suspected of COVID-19 by their healthcare provider.
Results are for the identification of SARS-CoV-2 RNA.The SARS-CoV-2 RNA is generally detectable in upper and lower respiratory specimens during the acute phase of infection.
Positive results are indicative of the presence of SARS-CoV-2 RNA; clinical correlation with patient history and other diagnostic information is necessary to determine patient infective status. The agent detected may not be the definite cause of disease. Positive results do not rule out bacterial co-infection with other viruses.
Negative results do not preclude SARS-CoV-2 infection and should not be used as the sole basis for patient management decisions. Negative results must be combined with clinical observations, patient history, and epidemiological information. The COVID-19 RT-PCR Detection Kit is intended for use by qualified trained clinical laboratory personnel specifically instructed and trained in the techniques of real-time PCR and in vitro diagnostic procedures.
