Sowing preparation
The seeds of imperial flowers are wrapped in prickly shells, like chestnuts. The seeds need to be peeled out, otherwise the shell should not be broken. Some flower friends refrigerate the seeds for a period of time before sowing, but in fact, direct sowing is also possible p>
The planting soil of emperor flower needs slightly moist sandy soil, in which a little base fertilizer can be applied p>
Seedling maintenance
It takes about 1-2 months for imperial flower seedlings to grow 4-5 true leaves. At this time, they can be transplanted in pots. The basin soil for sowing seedlings need not be too wet and can be kept slightly dry. The transplanted seedlings should be maintained in a place with sufficient ventilation and light p>
Cutting
Selection of cutting branches of imperial cuttings
Select the female parent of imperial flower, cut the branches above the semi lignified position as cuttings, and retain 4 ~ 6 leaves. The base of cuttings was soaked with 1000 ppm indole-3-butyric acid solution and dried immediately after soaking for 15 minutes p>
Cutting matrix
The cutting matrix of imperial flower is mixed with peat and perlite according to the volume ratio of 4:6, the pH value is adjusted to 5.5 ~ 6.5, and the EC value is less than 0.5 p>
Cutting
The cutting depth is 1 / 3 ~ 1 / 4 of the cutting length. After cutting, it shall be managed according to conventional technology, and field transplanting shall be carried out after seedling emergence p>
Breeding seedling maintenance
Whether it is sown or cutted imperial flower seedlings, they prefer too wet basin soil. They only need to keep the basin soil slightly dry. However, the air humidity can be appropriately increased, spray water around the plants, and keep the air humidity greater than 50% p>
