The method of Cuttage Propagation of soft Branch Yellow Cicada

The cultivation difficulty of the soft branch yellow cicada (details) is not high, and the flowering period is long and the flower color is bright, so it is very suitable for ornamental. In fact, the soft branch yellow cicada also has a certain medicinal value, and it has a certain effect on detumescence and killing insects. In general, artificial propagation of soft wood yellow cicada can be done by cutting.

The soft branch yellow cicada is generally propagated by cuttings. In spring and autumn, 1-2-year-old full branches are selected, cut into cuttings with 15-20cm length and 4 nodes, and cut into plain sandy soil. They are placed in a place with bright light, often keep moist, and take root in about 20 days at 20 ℃ temperature. When the seedling is high and 10cm, the heart can be removed and transplanted or put on the basin. It is worth noting that after cutting the cuttings from the mother plant, the milk of the incision must be completely dry before it can be inserted into the sand bed, otherwise the survival rate is not high.

Breeding methods and matters needing attention of soft branch yellow cicada

The soft branch yellow cicada is native to Brazil and is introduced into cultivation because of its large and colorful flowers. How do soft-branch yellow cicadas reproduce? What should we pay attention to in the process of reproduction? Next, let's take a look at the breeding methods of the soft branch yellow cicada and the points for attention in the breeding of the soft branch yellow cicada.

1. Breeding methods of soft branch yellow cicada

The soft branch yellow cicada is usually propagated by cutting. Generally, medium-ripe branches are cut in spring and autumn to grow 12cm-18cm. There are 2-4 stem nodes on the cuttings, which should be inserted obliquely on the loose seedling bed in time to keep it moist and avoid too much water. The suitable temperature is very easy to survive, and the optimum temperature for the growth period is 22 ℃ ~ 30 ℃.

In spring and autumn, 1-year-old and 2-year-old branches were selected and cut into 15-20cm long cuttings with 3-4 nodes and inserted in plain sandy soil. The cuttings were placed in a place with bright light and often kept moist. They took root in about 20 days at 20 ℃. When the seedling is high and 10cm, the heart can be removed and transplanted or put on the basin. It is worth noting that after cutting the cuttings from the mother plant, the milk of the incision must be completely dry before it can be inserted into the sand bed, otherwise the survival rate is not high.

2. Matters needing attention in breeding of soft branch yellow cicada

The main results are as follows: 1. The optimum temperature of soft branch yellow cicada is 20 ℃ ~ 30 ℃, which is lower than 20 ℃, the rooting of cuttings is difficult and slow, and the upper and lower cuttings of cuttings are easy to rot when the temperature is higher than 30 ℃, and the higher the temperature is, the greater the proportion of rot is. When there is a low temperature after cutting, the main measure of heat preservation is to wrap the flowerpots or containers used for cutting with thin film; when the temperature is too high after cutting, the cooling measure is mainly to shade the cuttings and cover 50% to 80% of the sun.

2. The soft branch yellow cicada must keep the relative humidity of the air at 7585%. The basic requirement for cuttings to take root is to ensure that cuttings are fresh and tender and can be used to produce rooting substances before they take root. However, cuttings without rooting can not absorb enough water to maintain their water balance. Therefore, it is necessary to reduce the water evaporation of cuttings by spraying. Under shaded conditions, the cuttings are sprayed 3-5 times a day. The higher the temperature in sunny days, the more the times of spraying, the lower the temperature in cloudy and rainy days, the less or no spraying.

3. The soft branch yellow cicada is inseparable from the sun, because cuttings have to continue to carry out photosynthesis to produce nutrients and rooting materials to supply their rooting needs. However, the stronger the light, the higher the temperature in the cuttings, the more exuberant transpiration of cuttings, and the more water consumed, which is not conducive to the survival of cuttings. Therefore, it is necessary to cover 50% to 80% of the sun after cutting, and then gradually remove the shading net after the root system grows.

The above is the soft branch yellow cicada breeding methods and soft branch yellow cicada reproduction points for attention introduction, want to breed their own soft branch yellow cicada friends, you can refer to oh. Improve the success rate of reproduction.

Key points of cultivation of soft branch yellow cicada

The florescence of the soft branch yellow cicada is from June to October, with a long flowering period and bright colors. In the south of China, the soft branch yellow cicada can blossom almost all year round. The artificial cultivation of the soft branch yellow cicada is not difficult, and it is very suitable for viewing. The editor will introduce the main points of the cultivation of the soft branch yellow cicada to you.

The growth environment of the soft branch yellow cicada likes high temperature and humidity, so it is a positive plant, so the cultivation place needs all-day sunshine. The cuttage method is generally used to propagate, and spring and autumn are the appropriate periods. The best soil is sandy loam or rotten leaf soil with good drainage. The focus of water management is to keep the soil slightly moist.

The soft-branch yellow cicada is native to tropical America, and then in the environment of high temperature and high humidity, it is not resistant to cold, and it is suitable for fertile acid with good drainage. After potted soft-branch yellow cicada leaves the house in spring, place it in semi-shady and humid places such as the north of the house. It is appropriate to trim or cut withered branches, weak branches and branches that disturb the tree shape, and apply fertilizer and water several times to promote the germination of new techniques, such as higher plants and lower detachment. The sprouting strip of the root can be properly retained and coring to gradually replace the renewal of the old plant. Usually boil water without being dry and immediately irrigated, and should often spray water to the plant and its surroundings to improve the environmental humidity. Fertilization was applied once every 7-10 days in the growing season, and manure and superphosphate were used alternately to ensure the growth and fullness of branches and long-lasting flowering period. After entering the house in winter, the room temperature should be kept above 10 ℃, and the basin soil should be moist. If the temperature is too low or if it is not dry or wet, it will cause the leaves to fall off.
