In winter, when the outside temperature is low, during the breeding period of winter shed pepper, it is often attacked by cold currents. The temperature suddenly decreases and the seedlings are susceptible to freezing injury. The severity of frost damage in seedlings is also related to the speed at which the temperature rises after low temperatures. Therefore, effective measures should be taken to prevent freezing.
First, the use of artificial temperature-controlled seedling raising methods, such as electric hotbeds and industrialized seedlings, etc., is the fundamental measure to solve the freezing problem of seedlings.
Second, in the rain and snow during the low temperature, make full use of the weather to clear the gap, remove the grasshopper, so that the pepper seedlings can be exposed to sunlight. When the snow and snow suddenly stopped turning, no more than a few grasshoppers were placed on the seedbed before and after noon to prevent the seedlings from losing water and wilting. Bed soil moisture, seedlings vulnerable to frost damage, so before the onset of cold waves to control seedbed watering, bed soil too wet to sprinkle a layer of hay ash.
Third, increase the application of phosphorus and potassium fertilizers, use cold resistance at the seedling stage. Seedlings sprayed with 0.5%-1% brown sugar or glucose solution can enhance cold resistance. Spray 0.5% calcium chloride solution twice at intervals of 7 to 4 days (7 days apart) to enhance cold resistance.
During the cold wave period, the seedbed was closely covered. When ventilation is performed for a short period of time, cold air must be prevented from directly blowing into the bed. Cover straw at night. The straw leaves can be sprinkled on the seedlings and cleared after the cold wave. In the snow days, after the snow stopped, the snow was promptly cleared out of the nursery site.
Hospital Bed, also known as hospital bed, Hospital Equipment, Nursing Bed, etc., is a hospital bed used by patients when they are hospitalized in the hospital.
There are many classifications of medical beds, and the specific classification methods are as follows: According to the material, it can be divided into ABS medical beds, all stainless steel medical beds, semi-stainless steel medical beds, all steel sprayed medical beds, etc.
According to the function, it can be divided into electric medical beds and manual medical beds. Among them, electric medical beds can be divided into five-function electric medical beds and three-function electric medical beds. Manual medical beds can be divided into double-shake medical beds and single-shake medical beds. Medical beds, flat medical beds.
According to whether it can be moved, it can be divided into a wheeled medical bed and a right-angle medical bed. Among them, electric medical beds are generally movable with wheels.
In addition, there are other special function beds, such as: ultra-low three-function electric bed, Hospital Bed For Home, hospital bed with bedpan, scald rollover bed, rescue bed, mother-child bed, crib, child bed, ICU monitoring bed, examination bed, etc.
