Star pocket sowing, need to choose a special sowing pot, such a pot convenient and fast, good water permeability, will not affect the growth of seedlings
The sand with good drainage, certain aeration and rich calcareous is suitable for planting. The specific operation is as follows:
1. The first step is to cover the bottom of basin soil with a layer of coarser cinder, which can effectively block the excess water at the bottom.
2. Before soil loading, the potted soil must be filtered and screened to remove some soil with larger particles, and then put it into the flowerpot, covered with a thin layer of fine sand, which can be gently shaken and shaken, so as to make the soil closer.
1. The pot soil needs to be disinfected before sowing. It is recommended to use potassium permanganate. The concentration can be determined by the color. It is best to present transparent red color. If it is too thick, the seeds will be burnt out. If it is too thin, it will not disinfect.
2. It can be soaked in the adjusted disinfectant solution together with the flowerpot, so that the soil can fully absorb potassium permanganate. After the surface soil is wet, it can be taken out. Drain the excess water, put it for two to four hours, and then it can be seeded.
Seeds can be sown one by one, so it will be very convenient to move seedlings later. Now point a hole in the soil and put the seeds in. It can also be spread directly on the surface of the soil, but it needs to be even.
1. After sowing, spray bactericide solution, select "carbendazim" or "thiophanate methyl" and spray evenly according to scientific proportion, and remember to cover the cover after completion.
2. Place the seedling basin at a temperature of 33 ℃ and keep the temperature difference between day and night above 15 ℃. Some seeds need a longer time to emerge. Generally, they will not emerge until one week later.
3. If you use a clay basin, pottery basin or plastic basin for sowing, you can choose to cover a layer of fresh-keeping film on it after sowing, which can not only improve the humidity and temperature of the surrounding environment, but also effectively help the seedlings to isolate external bacteria and pests.
