First, continue to strengthen the management of rice paddy field. Pay attention to the temperature control and reasonable ventilation management; then strictly control the watering. Pay special attention to the “give the fat fertilizer†3-5 days before transplanting. The dosage is the same as that of the fertilizer. At the same time, spray the Lego or Kang broadband medicine and bring the fertilizer to the ground.
Second, to ensure the quality of paddy land preparation. Grab the field and turn the ground. Use the shallow water of the paddy leveling machine to lighten the water, the general squatting ground can be slightly deeper; turn the ground as far as possible, turn flat, turn over to 15 cm or more, pay attention to the pool reinforced. After the ground, the paddy field is required to be leveled, and the height difference is no more than one inch. Third, advocate the deep application of fertilizer in the paddy field. The best way to apply deep fertilizer is to apply it before the paddy field is turned over, not only to do the deep fertilizer application, but also to improve the fertilizer utilization rate. Fourth, the paddy field weeding should be flexible. For plots with severe grassland shortage or serious water leakage, the paddy field can be sealed; for most of the old paddy field, the grassland is not serious, and the method of weeding after one-time formula is adopted as much as possible to prevent the two drugs from causing phytotoxicity.

COVID-19 Antigen Rapid Test
The COVID-19 Antigen Test Cassette is immunoassay based on qualitative membrane strip for the detection of COVID-19 antigen in anterior nasal swab
specimen. In this test procedure, anti-COVID-19-N antibody is immobilized in the test line region of the device. After an anterior nasal swab specimen is placed
in the specimen well, it reacts with anti-COVID-19-N antibody coated particles that have been applied to the specimen pad. This mixture migrates chromatographically along the length of the test strip and interacts with the immobilized anti-COVID-19 antibody. If the specimen contains COVID-19 antigen, a colored line will appear in the test line region, indicating a positive result. If the specimen does not contain COVID-19 antigen, a colored line will not appear in this region, indicating a negative result.To serve as a procedural control, a colored line will always appear in the control line region, indicating that proper volume of specimen has been added and membrane wicking has occurred.
