What are the breeding methods and matters needing attention of desert roses with flowers shaped like trumpets? How can the root become bigger?

Desert rose, also known as Tianbao flower, is not a rose growing in desert areas, nor is it closely related to or similar to roses. It is drought-resistant, beautiful when it is in full bloom, and is often cultivated and ornamental. So do you know the breeding methods and precautions of desert roses? How can the roots get bigger?

I. Culture methods and matters needing attention of desert roses

1. Desert roses are mainly propagated by sowing and cutting. It is better to sow in spring, and the method of spot sowing is used to facilitate the management after emergence. Be sure to disinfect the substrate before sowing. After emergence, pay attention to the substrate in the sowing plate should not be too wet, otherwise the roots may rot and cause a large number of seedlings to die. It is better to cut in the vigorous growing season. Cut the branch into about 10 cm, soak the lower end in water and dilute the mucus at the cut to prevent cementation from affecting the hairy root. It can be inserted into the sand bed or directly into the sterilized cultivation substrate, and it can take root in about 15-30 days. In reproduction, it is recommended to use sowing method to propagate, so that the plant rhizome can naturally expand to form a good plant shape. Cutting seedlings can not, but also greatly reduce the ornamental value.

2. In addition, in cultivation, the branches of desert roses are easy to grow, which affects the beauty of plant shape, so the plant shape can be changed by grafting. All the branches can be cut off according to a certain shape at a certain height of the plant, and then the upper end of the cut branches can be grafted by split grafting. The plant shape of the grafted plant is beautiful, and the flower branches are compact and ornamental after flowering.

3. Desert roses are more resistant to drought, and should not be watered too much each time. If there is more water, it is easy to cause root rot, and the branches are too long, so it is troublesome to prune. When it is hot in summer, it can be watered according to the soil condition. It is usually watered once every two or three days, and no water can be accumulated in the basin. As the temperature drops in winter, desert roses also enter a semi-dormant period, so properly control watering, keep the soil dry and water once a week. Proper drought is very beneficial to the growth of desert roses. The leaves of winter desert roses fall off gradually when they enter the dormant period, which is normal, so there is no need to be nervous about it. ]

4. Desert roses prefer phosphorus and potassium fertilizer and usually replenish it once a month or so. During the peak growth period in summer, sufficient fertilizer and water are needed so that the flowers can be luxuriant and bright. In addition, combined with the annual basin change, you can also properly apply some long-term base fertilizer in the basin, such as rotten bean cake, bone meal and so on.

5. The pruning of desert roses is also very important. If you do not pay attention to the usual pruning and let it grow, it is easy to lose its ornamental value. After flowering is the best time for pruning, you can make a choice according to your personal preference. Note: if you have more branches, you will blossom more. If you want to get more flowers, you must find ways to keep more ramets.

Matters needing attention in breeding Desert Rose

1. The leaf spot disease of desert rose is serious, which can cause a large number of leaves to fall off. It can be controlled with 25% carbendazim wettable powder and 50% topiramate 1000 times.

2. The main pest of desert rose is shell insect. When it is serious, it will cause all the leaves to fall off, plant growth point necrosis, and even plant death. Family cultivation should pay attention to observation, as soon as found that immediately with a cotton swab dipped in water to erase it. It can also be sprayed twice with 40% omethoate EC 1000-2000 times or 50% fenitrothion EC 1000 times during the spawning and incubation period. [attention should be paid to the safety of drug use when carrying out pest control. ]

3. Key points of maintenance: [good sunshine], [temperature of about 30 ℃], [watering of basin soil after drying], [proper fertilization in spring and summer rainy season], [dropping basin soil and changing basin at appropriate time]

Second, how do desert roses grow bigger?

1. Watering

The principle of watering desert roses is that the soil is watered as soon as the soil is dry. It means that the soil can be observed and watered once if it is too dry.

If you are afraid that the watering method according to the observation method is not accurate, you can reach the depth of 2 to 3 centimeters of the soil by hand. If it is still dry here, you should water it. Be careful that enough water should be watered, and there should be no dryness in the noodles. But there can be no stagnant water, otherwise it is easy to let the desert rose roots rot.

Watering is best in the morning or in the afternoon, the most avoid midday watering, especially the high temperature at noon plus the sun in the sun, when watering, the evaporation of moisture can scald plants.

At the highest temperature in summer, you can pour carbendazim water once or twice.

2. Soil

The soil where desert roses are raised is preferably sandy.

3. Fertilization

Give priority to fertilizer containing phosphorus, and some green leaf fertilizer can be applied in daily life.

In addition to growing the roots of desert roses to increase their appreciation value, pruning is also very important. In daily management, attention should be paid to reasonable pruning, so that there is no need to lose too much nutrients, and a more beautiful outline can be trimmed.
