The grafting method of Daisy requires high technical conditions, and the propagation process is rather complicated. Without superb cutting, grafting techniques, selection of improved varieties, artificial pollination and other technologies, it is difficult to reproduce successfully. This method of propagation can only be carried out in nursery when a large number of seedlings are needed.
Family Daisy can be propagated by sowing, splitting and cutting.
In the south, most of the seeds are sown from August to September in autumn. In the north, most of the plants are planted in spring or autumn, but in winter, daisies should be moved into a relatively warm indoor environment.
The seeds shall be evenly mixed with fine sand for sowing, and the fine soil shall be covered with a thickness of about 0.5cm. After sowing, the sunshade net shall be covered and water shall be poured through. Water should be sprayed carefully to prevent the soil surface from hardening.
Keep the temperature at about 28 ℃ after sowing, and cover with plastic film in early spring when it is cold and rainy to keep the soil moisture and temperature. After about 10 days, the seedlings are unearthed, the sunshade net or plastic film is removed, and the seedlings can be transplanted to the field when they have 2-3 pieces.
Due to the large variation of seedlings, some good varieties can be propagated by the method of plant division, but the growth potential of seedlings is not true, and the seed setting is poor. In the middle and last ten days of March, the old chrysanthemum vegetable can be dug out to expose the root neck, and the lateral buds of the existing root system and the old root can be cut off and transplanted into the new basin. Ramet propagation can be carried out at the time of sprouting new shoots.
Cuttage Propagation can be carried out in the whole growing season, and the survival rate of cuttage from April to June is the highest.
It is better to mix new soil into the seedbed with composted organic fertilizer.
The branches with 3-5 nodes and 8-10 cm long were cut, and the leaves at the base were removed. The depth of penetration was 1 /3-1 /2 of the length of the cuttings.
Keep the soil moist after cutting, avoid waterlogging, and cover it in high temperature season.
