Propagation methods and matters needing attention of Dutch Chrysanthemum

Dutch chrysanthemum is a persistent root flower of Aster of Compositae, which is a common ornamental plant for arranging flower beds and flower borders. Many flower lovers also like to make Dutch chrysanthemum into potted plants for cultivation. Some flower friends still want to breed on their own after cultivating Dutch chrysanthemum, so what methods should be used for Dutch chrysanthemum reproduction and what should be paid attention to?

Dutch chrysanthemum

First, sowing and reproduction

The sowing time is about the first ten days of March. Pot sowing or border sowing in a warm sunny place in the greenhouse. Under the condition that the room temperature is not less than 15 ℃, the seedlings can be produced in about 7 days. When the seedling height is about 5cm, the first planting should be carried out in time so as to avoid overgrowth. You can choose a small diameter 12cm pot or separate planting in the border. The second planting was carried out in the first ten days of May, and it was planted in a large pot or directly according to the need. The distance between plants planted in the ground should be controlled at about 40cm to facilitate its further tillering and proliferation.

2. Tillering propagation

The tillering ability of Dutch chrysanthemum is very strong, and the tillering plants can be cut off and planted separately. The planting time is generally selected after the soil is thawed in early spring and the mother plant has just grown tufted leaves. Dig out the overwintering underground roots, cut the original dunes into several pieces with a knife, and plant them respectively, and the survival rate of tiller seedlings is very high. Perennial plants can be propagated in large numbers by this method.

3. Cutting propagation

Perennial plants produce a large number of tillers after the beginning of spring. The young tillers can be cut down for cutting with a knife. Using plain sandy soil, perlite and vermiculite as substrate and keeping the temperature above 20 ℃, shading or full light spraying device should be used to keep the air humidity, which can take root in about half a month. Rooting plants can be directly planted into the basin or into the bed.

IV. Grafting cultivation

Using wild Artemisia annua as rootstock for grafting cultivation, the effect is better. The specific methods are as follows: at the end of November or early December, the Dutch chrysanthemum will pick the residual flowers and turn the pot to change the soil. When the outdoor temperature drops to about 5 ℃, move the pot into the low-temperature greenhouse, do not enter the medium-temperature or high-temperature room, so as not to sprout and grow, making the chrysanthemum seedlings weak. After the Beginning of Spring the following year, he moved the potted chrysanthemum to an outdoor shelter, and Ching Ming Festival poured some people's feces and urine and other thin fat water before and after. Artemisia annua seedlings were dug up from the field from the end of April to the end of June, and planted in a 5-inch or 7-inch mud basin. In June and July, according to the growth size of Artemisia annua plant, it was changed into a 10-inch mud basin, and thin fertilizer and water were applied every 5 days. When the stem of Artemisia annua is 15 cm high, Dutch chrysanthemum can be grafted by split grafting. After grafting, the Dutch chrysanthemum can be moisturized with a small plastic bag and survive in about 7 days. It should be noted that the height of the rootstock is about 15 cm. If it is higher than 20 cm, the Dutch chrysanthemum will feel top-heavy and unstable in the later stage. Secondly, if the inner core of the grafting interface of Artemisia annua rootstock has been white aging, it is not suitable for grafting, because it is not easy to survive after grafting, even if it survives, it will make the scion ossified. After the grafting of Dutch chrysanthemum survived, thin fertilizer and water can be applied frequently, which is like the cultivation of autumn chrysanthemum in management. At ordinary times, Dutch chrysanthemum can be oriented to pick the core according to the shape of spherical or flat steamed bread, but the last core picking needs to be carried out at the same time. If you need to blossom on National Day, you can pick the core for the last time in Lesser Heat (early July). If you need to blossom in the autumn chrysanthemum exhibition, you can do the last time in late July.

Soil

Dutch chrysanthemum can tolerate barren and has low requirements for soil, but loose and fertile sandy soil is the best choice.

Reproduction method

The main propagation methods of Dutch chrysanthemum are sowing propagation, cutting propagation, grafting propagation and tillering propagation. The methods of sowing and tillering are commonly used.

Matters needing attention in the Culture of Chrysanthemum morifolium

Dutch chrysanthemum will be infected with many diseases and insect pests in the process of growth, including powdery mildew, mosaic disease, rust and so on. Once it is found that Dutch chrysanthemum is infected with diseases and insect pests, it needs timely treatment, spraying chemicals, and paying attention to ventilation and humidity control in the process of breeding.

Pruning

Dutch chrysanthemum is more resistant to pruning. In the process of growth, timely pruning can make Dutch chrysanthemum more branched and blossom.

To grow in vain
