Propagation method of primrose

Cuttage Propagation of Primrose

The annual sturdy branches were cut in early spring, or the semi-lignified branches were cut from July to August as cuttings with a length of 8 ~ 10 cm. The leaves at 3 points at the base were removed and tied into a bundle of 20 branches, which were soaked with rooting stimulants, which were generally treated with indoleacetic acid, indolebutyric acid, naphthylacetic acid or rooting powder, dissolved in alcohol (ethanol), and then prepared with distilled water to achieve the desired concentration.

The concentration of rooting stimulation agent solution is 0.01%-0.02%. Put the prepared solution in a container, then put the cuttings upright into the container, soak the base of the cuttings for about 2 cm, soak for 24 hours, and then take out the cuttings and cut them on the prepared cuttings. A shade shed should be built above the bed, and a bow-shaped plastic shed with a height of 60-80 cm should be set up to maintain the temperature and humidity of the bed; the temperature of the bed should be 20-25 ℃ and the humidity is about 80%. The cuttings began to take root three months after cuttage, and the roots developed into seedlings in five months. You can turn the bed and get up the seedlings. Those who take root and grow seedlings are transplanted into containers to cultivate strong seedlings and come out.

[method of reproduction]

Use more cuttings. Select 1-year-old branches, cut them into 15cm length, pour water through the whole seedling bed, and then cut them after water infiltration. It can also be dried, that is, after cutting in the whole seedbed, it can be filled with water. Cutting can be carried out from mid-October to mid-November or in spring. After rooting, it can be planted separately, and it can also be propagated by ramet or striping.

Cultivation and modeling

Yingchun forms flower buds on one-year-old branches and blossoms in the following spring, so all flower branches should be cut short after flower fade every year to promote the growth of more lateral branches, increase the number of flowers, and strengthen fertilizer and water management at the same time.

Diseases and insect pests:

Leaf spot and branch blight often occur in diseases and insect pests, which can be sprayed with 1500 times of 50% bacilli special wettable powder. Insect pests are harmful to aphids and coir moths, which are sprayed with 1000 times of 50% phoxim EC.

The cultivation of senior cadres to welcome the spring

The salmon seedlings with breast diameter above 2cm can be grafted at lm or at a certain height when they germinate in early spring. Yingchun branch Chang 8-l0cm was used as scion for grafting. After that, tie it tightly with thin film, cover it with a plastic bag, and gradually tear the bag into a breathable and ventilated seedling after survival, and pick the heart to promote the extraction of side branches to cultivate the crown.

Suitable range

Native to the subtropical regions of South China and Southwest China, cultivation is very common in the south, can be grown in North China and Henan, and is cultivated and produced in the whole county of Qianling.
