First, seed treatment
After selecting a good variety, the seeds are first dried for 4 hours, then disinfected with trisodium phosphate solution, and then soaked in fresh water for about 8 hours.
Second, normal temperature germination
About 30 °C is the appropriate temperature for germination. Soak the soaked seeds in cotton cloth and moisten with a plastic film. The seeds are rinsed with clear water every half-day, and then germinated again for about 60 to 70 hours. When the buds are about 3 mm long (at this time, the seed is whitened), sowing is best. If the seeds cannot be sown in time, the seeds should be stored under the condition of about 8°C, and the sowing conditions should be created as soon as possible.
Third, the preparation of the plug
Special nursery medium and 72 hole trays are used. The vegetable farmers can calculate the number of nursery trays and nursery media needed according to their own needs. The nursery medium is mixed with an appropriate amount of phosphorus-potassium compound fertilizer, special biological micro-element fertilizer and other trace element fertilizers, etc., and the water is stirred evenly, and then the plug tray is leveled (scrape with a straight wood board).
Fourth, prevent high temperatures
After sowing, the plug tray was irrigated and sprayed with Precise to prevent disease. After that, the cover membrane was moisturized. At this time, we should pay attention to shade and cool down, prevent steamed seeds from affecting sprouting. At this time, the temperature should be adjusted below 30°C during the day, and below 18°C ​​during the night. When the emergence is about 80%, the plastic film can be peeled off. With the growth of the seedlings, the time for covering the shade net can be shortened, which is more conducive to the growth of seedlings.
V. Prevention of drought
After sowing seedlings, always pay attention to the humidity of the seedbed, do not over-wet or dry. Some vegetable farmers are afraid that the seedlings will grow too long and they will control watering. This will lead to over-drunk plugs, which will cause capillary roots to lose water and be dry and injured. This will affect the ability to absorb and form weak seedlings and become susceptible to disease. Therefore, it is advisable to water it properly when it is watering.
Sixth, prevention seedlings leggy
Pepper seedling growers are mainly due to high night temperatures, strong respiration, excessive nutrient consuming, and then nitrogen fertilizer and moisture fully cause the seedlings to grow. In addition, the seedlings are too close to each other to block the sunlight, affecting photosynthesis can also cause leggy. Therefore, the prevention of seedlings should pay attention to the prevention of excessive nighttime temperature and excessive humidity inside the plug; secondly, less nitrogen fertilizer should be used during fertilization; the third is to increase the distance between the trays when the seedlings grow to a certain size. Transmit light, strengthen photosynthesis to avoid seedlings growers.
VII. Prevention of heavy rain damage
When the seedbed is set in the shed, usually a film and net covering method (plastic film plus shade net and insect net) is used. When there is heavy rain, the shed film can be pulled down to prevent the rain from showering on the seedlings and the rain-borne germs. .
VIII. Prevention of pests and diseases
At this stage, because the external environment is more conducive to the occurrence of pests, pest control should also be strengthened. For example, in the breeding nursery sheds, insect pests are used to set yellow plates to attract whiteflies, and blue plates are used to trap and kill the thrips. If necessary, use pesticides for control. The diseases that should be strengthened at this time are the damping-off at the seedling stage, blight and viral diseases in the middle growth period. In addition to the seed disinfection, seed bed disinfection is also required. Sprinkling to the Nong 4 or Miao bacteria can be performed after sowing. Mixed into harvest No.1, can effectively inhibit the soil seedling disease, but also enhance the development of seedling root system, promote Miao Qi Miao.
Washable Underpads are reusable pads that are designed to protect
mattresses, chairs, and other surfaces from urine, sweat, and other
bodily fluids. They are made from absorbent materials such as cotton,
polyester, or a combination of both, and have a waterproof backing to
prevent leaks.
Washable underpads come in a variety of sizes and absorbency levels, and
can be washed and dried in a standard washing machine and dryer. They
are a cost-effective and environmentally friendly alternative to
disposable underpads, and are ideal for individuals with incontinence
issues, bedridden patients, and those who are recovering from surgery or
illness.
Some washable underpads also feature antimicrobial properties to prevent
the growth of bacteria and odors, and others have non-slip backing to
keep them securely in place. They are easy to use and maintain, and can
provide peace of mind and comfort for both patients and caregivers.
