Before the seed emerges, the water storage depth of the pond in the nursery shed is deep(200 cell seedling trays wholesale), the humidity is too high, and the greenhouse is not treated with air in a timely manner, which causes the humidity of the nursery substrate soil to be too high, which causes the seeds to breathe difficultly, rotten seeds, and failure to emerge(72 cell seed trays). It has a great impact on pepper farmers' planting and production of pepper.

A method of raising seedlings by promoting the development of the root system and floating the plug tray on the water surface so that part of the pepper seedlings grow in the seedling substrate and absorb water and nutrients from the substrate and the water bed(32 cell seedling trays wholesale). Obtained, at this time insufficient nutrients in the substrate or pool will cause yellowing of the seedlings, weakening of the growth and infection of the disease, and the emergence rate is greatly reduced(200 cell seed starter trays).
As a result, seed rot or seedling infections such as bacterial wilt disease and cataplexy disease(15 gallon nursery pots wholesale). The planter's seeding time is advanced and affected by the continuous low temperature weather conditions in early spring, but no temperature increase measures are taken, which results in the low seedbed temperature in the seedling shed(spill trays wholesale). In the low temperature period, a small shed film can be covered in the greenhouse to increase the temperature and protect the seedlings.
Adhere to the principle of giving priority to prevention, controlling disease conditions, and reducing the number of pathogens(3 gallon nursery pots wholesale). The seeds in the plug tray germinate until the first true leaf grows. During this period, nutrients are mainly supplied by the organic nutrients stored by the seed embryo itself(18 cell seed starting trays). After the true leaves begin to show, the nutrients required for the continuous growth of the seedlings must be from the substrate or the surrounding environment.
The optimal temperature for pepper seeds to germinate is 25-30 ℃, and it is not easy to germinate below 15 ℃(nursery pots). Above 30 ℃ will seriously affect pepper emergence and normal growth of seedlings. After emergence, the optimum temperature is 25-30 ° C during the day and 15-18 ° C at night. The proper temperature must be ensured(20 cell seed starting trays). If the temperature is too high, the film should be removed or the ventilation opening should be opened in time to cool down.
In order to avoid pollution and reduce pathogens, the seedling bleaching tray must be disinfected before sowing(5 gallon nursery pots wholesale). So where is the problem? Let's explore it: In recent years, the seeds are difficult to germinate, the amount of watering before emergence depends on the soil moisture of the substrate. First of all, let's understand the principle of floating seedlings of floating peppers(40 cell seed starting trays). Floating seedlings are seeding pepper seeds in foam trays equipped with seedling substrates.
Although it is necessary to moderately control water and reduce the amount of watering after emergence in the nursery shed(7 gallon nursery pots wholesale), otherwise excessive humidity may easily cause sudden fall, blight, and gray mold. Pay attention to opening the shed for ventilation and dehumidification to increase the light, which is beneficial to the normal growth of the seedlings(40 cell seed trays). In addition, when the humidity in the floating nursery bed is too high, you can sprinkle grass and ash.
You can choose to re-spray the seedling substrate soil(seed starting trays). The bottom of the nursery pond, the film, and the water source must be disinfected to ensure that the water source and the shed film are cleaned inside and outside. Before the float plate enters the pond, 0.025% copper sulfate can be dissolved in warm water and added to the seedling pond to prevent green algae in the pond(50 cell plug flats).
