The key to management after planting is to control the conditions of water, fertilizer, gas, heat, and light, and to promote the balance between vegetative growth and reproductive growth. Through management, an environmental condition conducive to the growth of cucumber is not conducive to the occurrence of diseases, so as to achieve the goal of high yield and quality. . (a) The key to planting to temperate seedlings is temperature, which is maintained at 28-30°C during the day and not less than 15°C during the night. After the seedlings are replenished, the day-night temperature difference is increased to promote root control and lay the foundation for the start of the harvest. (II) Management during the result period The management of fertilizer and water management during this period is the key to obtaining high production, high quality and high efficiency. 1. Temperature and humidity adjustment During this period, four sections of variable temperature management are used to control temperature and humidity, and ecological disease prevention is performed. During the day, the temperature exceeds 30°C and the air is released. In the afternoon, the temperature is lowered to 20°C. The shed is maintained at 15-17°C in the middle of the night and 13-15°C in the middle of the night. , 25-28°C during the day. 2, water and fertilizer management root melon harvest before pouring a small water, with the increase in temperature, into the melon period of increased water demand, need 7-10 days to pour a water, combined with watering topdressing available fertilizer 15-25 kg / Acre, can also use 0.2% potassium dihydrogen phosphate for foliar dressing. 3. The method of adjusting the vines in the plant is to pull the wire upright at the upper end of the cucumber pods, and then pull the vines to draw the ropes after easing the cucumbers. The vines are bound every 4-5 times. When the growing point grows close to the shed, the lower yellow leaves and diseased leaves are removed. At the same time, too many male flowers and tendrils are hit.

Virus Specimen Collection Tube

Inspection principle:
It can perform protein denaturation on fresh clinical virus samples to inactivate the virus, prevent secondary transmission of infection, and ensure the safety of transportation and testing personnel.

♣. How to use
â‘  Before sampling, mark relevant information on the label of the sampling tube.
â‘¡. Sampling with the corresponding cotton swabs.
â‘¢ After the collection is completed, quickly put the cotton swab into the collection tube, break the part higher than the sampling tube, and tighten the tube cover.
â‘£. For the specific sampling method, please refer to the following:
a) Nasal swab Gently insert the sampling head into the nasal cavity, stop for a while and then slowly rotate to exit, immerse the collected specimen in the Xiangxiang solution, break the excess part and discard it, and tighten the sampling tube cover.
b) Pharyngeal swab: Wipe bilateral pharyngeal tonsils and posterior pharyngeal wall with the sampling head, immerse the collected specimen in the sampling solution, break off the excess part and discard it, and tighten the cap of the sampling tube.
c), Mycoplasma Chlamydia, Ureaplasma specimen collection
Male: Insert the sampling head into the urethra about 2cm and rotate, stay for a while and then exit, and immerse the collected specimen in the sampling solution.
Female: Wipe the mucus of the cervical orifice, insert the sampling tip into the cervical canal for 1-2 cm for sampling, immerse the collected specimen in the sampling solution, break off the excess part and discard it, and tighten the cap of the sampling tube.
♣. Precautions
1. After the virus is collected, the disposable sampling swab should be completely inserted into the preservation solution, so that the virus can be retained to the greatest extent possible.
â‘¡ The collected specimens must be sent for inspection in time.
â‘¢. It is forbidden to use products with damaged packaging and expired validity period to prevent pollution.
This single-use Virus Sampling Tube is used for in vitro diagnosis. It cannot be used for human or animal oral or external use. If swallowed, it may cause serious events; it is irritating to eyes and skin. If it is not splashed into the eyes, rinse with water.
