The propagation of evening primrose

Branching

Nocturnal incense has a strong sprouting ability, so we divide it into quantitative plants or several plants from the root to propagate. This method is fast, but it also has some limitations.

Cuttage

The most suitable for cutting propagation in spring and autumn, night incense propagation ability is strong, easy to produce adventitious roots, can take the mother plant into the soil for cutting, the temperature is about 20 degrees to propagate the fastest, acidic soil is conducive to cutting propagation.

High extraction pressure

The branches of Nelumbo nucifera are hard and should not be bent and drawn. During the growth period, cut off the skin at the branch bifurcation in the same year or the next year, wipe it with soil to the wound, wrap it with thin film, and then cut off the branches after rooting and plant them.

The above is the introduction of night incense breeding, I hope it will be helpful to you! Thank you for your reading!

The Propagation method of Euphorbia angustifolia the efficacy and function of nocturnal incense

Night incense is also known as night fragrance, night orchid, night clove, thousand-mile incense, and so on. Today, we will share with you the breeding methods and the efficacy and function of night incense.

The propagation method of evening primrose:

1. Branch propagation. The sprouting ability of night incense is relatively strong, the plant is divided into quantitative plants or several plants from the root to propagate, this method is fast, but it will also be limited.

2. Cuttage propagation. Cutting propagation is carried out in spring and autumn, night incense has strong propagation ability and is easy to produce adventitious roots. the mother plant can be inserted into the soil for cutting. the propagation speed is the fastest when the temperature is about 20 degrees, and the acidic soil is conducive to cutting propagation.

3. Take high pressure branches to propagate. The branches of Nelumbo nucifera are hard and should not be bent and drawn. During the growth period, cut off the skin at the branch bifurcation in the same year or the next year, wipe it with soil to the wound, wrap it with thin film, and then cut off the branches after rooting and plant them.

The efficacy and function of night incense:

1. The ornamental function of evening primrose.

The fragrant flowers at night are full of fragrance, bloom in the evening, and give off a delicate fragrance when you have dinner. Nocturnal incense blossoms in summer and autumn, with slender branches and leaves. In the south, it is planted in the courtyard, in front of the window, by the pond and by the pavilion. You can smell the aroma of nocturnal incense when you take a walk after supper.

2. The medicinal value of Corydalis.

Night incense can be used as medicine, with the effect of clearing the liver and eyesight, can treat eye swelling and pain, measles on the eyes, corneal nebula, and so on.

3. The edible value of evening primrose

Evening primrose is edible. Fresh flowers and buds are edible. It is a semi-wild vegetable.

4. Mosquito repellent effect of night incense.

Night incense is relatively strong, and has a certain toxicity, mosquitoes hate this smell, so night incense has a good mosquito repellent effect. Usually, evening primrose is planted outdoors for both ornamental and mosquito repellent.

The propagation method of nocturnal incense is commonly used to propagate by cuttings. let's take a look at how to propagate it in turn: 1. Select cuttings: branches with strong growth or no diseases and insect pests should be selected. on the same plant, we should choose the sunny branches in the middle and upper part of the year, requiring short internodes, stout branches and full bud tips, and should not choose branches and overgrown branches that are about to blossom. 2. The substrate was prepared with peat soil and rotten leaf soil according to 3 ∶ 3 ∶ 4 respectively. The bed soil prepared in this way has the characteristics of increasing bed temperature, water retention, aeration, fertility, partial acidity and so on, so it is suitable for branches to take root and sprout. 3. Treatment of cuttings: before cutting, cuttings were treated with ABT rooting powder and other chemicals, which could promote rooting. Cut the cuttings into a section of 8 cm to 12 cm, with 2 to 3 buds above. The cut in the lower part of the cuttings should be 0.5 cm below the node. The incision should be smooth, cut off the lower leaves, leaving only 2 to 3 leaves at the top, and the insertion depth is generally about 3 cm. 4. The conditions for rooting: the suitable rooting temperature is 20 ℃ to 24 ℃, and the general soil temperature is 3 ℃ to 5 ℃ higher than the air temperature. The relative humidity of the bed air is 80% to 90%, which is favorable for rooting and requires light of about 30%. The moisture should be suitable, which is slightly higher at the initial stage of cutting and slightly dry at the later stage. The suitable period for local open-field cutting is from early May to mid-June, which is in a better climate, which can better meet the temperature and humidity conditions needed for cuttings to take root. 5. Strengthen post-cutting management: after planting, it should be watered thoroughly, covered with plastic film, placed in a shaded place, or scattered grass on the film to prevent direct sunlight, and increase light at night to help the cuttings survive. Air is released once or twice a day to replenish the oxygen needed and prevent diseases. To often spray water, keep the inserting bed moderately moist, but do not spray too much water, otherwise the inserting bed is too wet, often affecting the cuttings healing and rooting. When the new root grows to 2 cm to 3 cm, it can be transplanted into the basin at the right time. Nanjing area should be moved into indoor maintenance in winter after flowering.
