"Plunge cut-off" against watermelon cracking fruit

Watermelon cracking is the most troublesome thing for melon farmers. There are two main reasons for cracking fruit: First, the melon is thin and can't withstand the long and long break. The second is uneven watering. When the weather continues to dry, sudden flooding with Da Lu or continuous continuous heavy rain will cause nutrients in the soil to enter the fruit with moisture, which will make the length and speed of the melon as much faster than the peel and cause fruit cracking. There is a "patch closure" approach that prevents watermelons from cracking. The method is: Before the furrow or heavy rain, cut two bamboo needles with a diameter of 1/3 of the guava, and insert the guarana into the vertical. This method can control the large amount of nutrients flowing into the fruit, preventing the larvae from fierce and breaking the melon skin. Of course, scientific ditch irrigation is very important.

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.
