Can manure produce non-polluted vegetables?
can. Earthworm manure is a black, uniform, natural earthy finely divided substance with good porosity, aeration, drainage and high water holding capacity. The manure contains not only various elements such as nitrogen, phosphorus and zinc, but also contains various trace elements such as iron, manganese, zinc, copper and magnesium and 18 kinds of amino acids. The organic matter content and humus content can reach about 30%. Because of its large surface area, cockroaches allow many beneficial microorganisms to survive and have the ability to absorb and retain nutrients. The cockroach dung is rich in bacteria, actinomycetes and fungi. These microorganisms not only mineralize complex substances into effective substances that plants can easily absorb, but also synthesize a series of biologically active substances such as sugar, amino acids and vitamins. The above properties of earthworms determine that it is an excellent organic fertilizer for the production of pollution-free agricultural products.

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.
