According to statistics, the economic losses caused by diseases in greenhouse production can reach about 30%, and the highest ones can reach more than 50%. Disease prevention and control is one of the main tasks of current greenhouse production, and the control cost accounts for more than 30% of the total production cost. How can we make crops in the greenhouse less sick or even sick? This requires the producer to properly regulate the temperature and humidity of the greenhouse. Most diseases occur and develop under conditions of low temperature and high humidity. The most scientific and economical measure to control the occurrence of diseases is to increase the temperature and reduce the humidity. The two conditions of low temperature and high humidity do not meet or shorten the meeting time. In general, the room temperature rises below 26°C and the humidity drops below 80%. Diseases rarely occur. How can we increase the temperature? In general, the first increase in lighting, increase the temperature of the greenhouse: the second is to check the plug pores, wither less heat loss; the third is to increase coverage, try to keep warm; the fourth is to dig good cold ditch, reduce ground conduction; Fifth, increase Organic fertilizer, using straw reactor technology, increase ground temperature and store heat energy. How can we reduce the humidity? In principle, it should be reasonable to ventilate and scientifically apply water. Planting period should be filled with bottom water, cover the plastic film, and reduce soil moisture to transpiration. In mid-fertility, the groundwater should be filled with small water to ensure that the soil is dry and wet. When fruit is full, pour plenty of water where appropriate, and let the air out. In the low temperature season and after the curtain is uncovered in the morning, if there is a large amount of fog in the room, it should be put in a small breeze for 5 to 10 minutes immediately. Then close the tuyere, wait until the temperature rises to 28 ~ 30 °C and then repeatedly put a small breeze. It is advisable to keep room temperature above 25°C in the afternoon before curtaining. Close the tuyere when watering, raise the indoor temperature to above 32°C, and allow the surface water to evaporate into water vapor as soon as possible so as to remove moisture through ventilation measures. When the humidity is too high at night, it is necessary to take warm-up measures to increase the temperature and prevent the bacteria from invading after the foliage surface is dew. Short Tubes For Urine Bag Connection
Short tubes connected or welded between urine bag and urine bag valve (such as cross valve, push/pull valve, lever valve, sampling valves, T valve) are urine bag parts, which is usually give urine bag and valve a good connection, so as to realize a nice function performance.
Urine bag are personal home or healthcare consumables, Huali's product are medical grade PVC, which is better for liquid control or management.
