The sowing period and sowing methods of succulent plants
The editor introduces you to the knowledge of succulent plants, including the sowing period and sowing methods of succulent plants. Let's follow the editor and have a look!
Determining the sowing period is a very important part of seedling raising, as it affects the growth period of the plants and the adaptability of the seedlings to the environment. Suitable sowing time can improve seed germination rate, ensure uniform seedling emergence, make the plants grow strong and resistant to stress, and is conducive to cultivating high-quality products.
Usually, the sowing period of plants is from April to October. The seedlings of cacti (within one year) do not hibernate in winter, so as long as there is a guarantee of minimum temperature in winter, sowing can be done during this period. It is best to sow succulent plants in two batches, with summer dormant types in September-October and winter dormant types in April-May.
21-27 degrees Celsius is the most suitable temperature for sowing cacti and succulent plants, and the germination rate of seeds is relatively high at this temperature. Therefore, it is best to sow cacti and succulent plants in spring and autumn. Moreover, there is a significant temperature difference between day and night during this time, which leads to more uniform seedling emergence and faster growth of the seedlings after emergence. A temperature difference of 15 degrees Celsius between day and night is most conducive to seed germination. However, when the day temperature exceeds 30 degrees Celsius, it is not very conducive to the growth of seedlings. Therefore, the sowing period of cacti and succulent plants should avoid summer. It is also not recommended to sow during the plum rain season, as the pathogen is active during this time, and the seedlings are prone to disease after emergence.
Direct pot sowing and seed soaking to promote germination are commonly used sowing methods. Direct pot sowing can be divided into spot sowing and broadcast sowing. When there are a large number of small seeds, broadcast sowing is generally used, that is, the seeds are slowly and evenly scattered in the seedling pot (be sure to disinfect the seedling pot). When there are few large seeds, spot sowing is generally used, that is, the seeds are individually placed in the seedling pot with a fingertip, pointed chopsticks, or a bamboo stick (be sure to disinfect the seedling pot).
Seed soaking to promote germination is mainly used for seeds that are difficult to germinate, such as those with thick seed coats. If direct pot sowing is used, the possibility of seedling emergence is very low. The specific operation method is: place the seeds in a shallow container, add a little water without submerging the seeds, and cover with glass in a dark place. After a few days, when the white cotyledons appear, the seeds can be transferred to a seedling pot (after disinfection and sterilization treatment) with a small tweezers and covered with glass.
The pots generally used for sowing are preferably shallow and large, and the material does not matter, but the pot mouth must be flat, only then can the glass be covered tightly. Seeds can be mixed-sown, as long as a label is inserted and the spacing is noted.
