Rice seedlings are affected by rain
April is a crucial period for rice breeding in our province. From April 3rd to June 6th, heavy rains occurred in most areas of our province, and severe convective weather such as thunderstorms and strong winds scattered in the local areas, which affected the growth of young rice seedlings of early rice and ratoon rice. In order to prevent unfavorable weather from occurring, the author has combed out the experts' suggestions to help you fight disasters, educate, educate, and breed crickets, reduce disaster losses to a minimum, and ensure that the rice area is stable. First, the Qinggou row of stains should pay close attention to clean up the field "Sangou" and Tianwai trenches, grab row of waterlogging, so that the rain to stay dry, trampoline car no water, to prevent the emergence of rotten species. At the same time, reinforce and repair plastic sheds and other breeding facilities to reduce the risk of strong wind and heavy rain. Second, the classification of management 1, factory breeding: early rice, ratooning rice generally on March 20 about sowing, the current two-leaf seedlings, growth is normal. In case of low temperature days to close the film insulation, the temperature above 13 °C, the rainy days but also to open a small window and two doors ventilation dampness hardening seedlings. Eye-catching air ventilation at 9-10 am will prevent seedlings from sprouting. Avoid sudden heat at noon. The timely spraying of "transplanting spirit" to prevent blight, spraying "big care" to promote the seedlings to restore normal growth as soon as possible. The surface of the trampoline is not white and water is not sprayed, and water is sprayed in the morning or the evening in case of water shortage. 2, small arch shed water Yujing: Early rice, ratooning rice generally sowed on March 25, the current two-leaf seedlings, rainy days to clean up the three ditch, to prevent flooding flooded seedlings, Tianjing first water after uncovering the film, the first two to open in the morning Thin film, ventilation and humidity increase, close in the evening, the next day can be film drying bed warming, spraying "transplanting spirit", "Bui care" and other disease prevention promote long roots, at night to cover film insulation. Membrane temperature 20-25 °C is appropriate, 2-3 days after refining seedlings, shallow water on the box surface, Mushi urea 3-4 kg raised. Third, timely changes in early rice with rotten seed damage can be changed to live early rice, rush to clear planting, seedlings of damaged renewable rice can be robbed seedlings changed to a season of rice.
Suction machine not only serve to
aspirate secretions, but also blood and other bodily fluids. The creation of
negative pressure can suck up liquid through an aspiration catheter using an
aspirator pump and then collecting it in an attached container. An aspirator is
often used when a patient's respiratory tract is being blocked with saliva,
mucus or blood and he, for any reason (e.g. unconsciousness), is not able to
cough it out.
In
this category, we offer you a selection of various Suction machine. Of course, you will also find the compatible
consumables for your secretion aspirator, such as Disposable Suction
catheter, PE gloves.
