Cutting time of Petunia

1. Suitable for cutting in Spring and Autumn period

Generally speaking, the cutting time of petunia can be divided into two periods: spring and autumn, in which the spring cutting time is from March to May and the autumn cutting time is from July to September. The effect of cutting in spring is the best, because spring is the most exuberant season for the growth of branches and leaves of Petunia, and more leaf juice and auxin are secreted in the plant. after cutting, its own cells divide more rapidly, and even root and cuttings quickly.

two。 It is not suitable for cutting in summer and winter

Because the best temperature of petunia cutting is 15 ℃ ~ 25 ℃, when the cultivation temperature is lower than 8 ℃ or higher than 30 ℃, it is not conducive to the rooting of petunia. Therefore, the survival rate of petunia cutting is relatively low in cold winter or hot and humid summer. Therefore, it is not recommended to choose summer and winter cutting.

When the cutting time of petunia is right, it is actually very simple and can greatly improve the success rate of cutting. In addition to cutting propagation, what other breeding methods are available for people who like it?

Can Petunia be cut? cutting Propagation techniques of Petunia

Petunia belongs to Solanaceae, Bidong eggplant, also known as Bidong eggplant. Herbs perennial, often cultivated in 2012, 20 Mel 45 cm tall; stems creeping, covered with sticky pilose. Many flower friends asked whether petunia can be cut, I told you this is sure, and petunia cutting is relatively easy to survive, as long as pay attention to the cutting season, choose ideal branches, generally speaking, the survival rate of petunia cutting is very high, the following editor will introduce the cutting propagation technology of petunia.

Cutting Propagation techniques of Petunia

I. selection and treatment of cutting branches

Choose a sturdy branch (the old branch is not easy to cut), cut off the stem near the bottom of the node, let the wound dry, remove all the buds and fruits on the cutting branch, and remove 2gambit and 3 leaves.

2. Selection of cutting media

More ideal is coarse sand, perlite and other coarse structure of the medium, because such a medium has good water permeability, conducive to rooting, of course, other media can also (remember to compaction the soil). For example, one part of rotten cow dung, one part of sawdust and two parts of soil can be mixed evenly into a nursery or basin, or half of plain sandy soil and peat soil can be mixed, or soil cuttings can be cultivated every other year. The cuttage flowerpot in the pot should not be too large, with a diameter of 15 to 20 cm.

3. Selection of cuttings

Cuttings should be collected before sunrise in the early morning, when the water content of the branches is high, which is beneficial to the rooting of cuttings. When cutting cuttings, cut the sturdy and pest-free branches from the base of the node, about 10 cm, and the cut should be flat. Leave 2 to 3 leaves at the top of the cuttings, half of which can be cut off if the leaves are too large.

Fourth, cutting season

Generally speaking, the cuttage survival rate of petunia in spring and autumn is higher than that in summer. The survival rate of cuttings is high in early spring and autumn, but low in high temperature season in midsummer, so it should be avoided.

5. Cutting methods

Insert the cuttings into the nursery or flowerpot with a depth of 2 to 3 cm, plant spacing of 6 cm and row spacing of 4 to 6 cm, so that the leaves stretch naturally. Cuttings in the greenhouse in early spring should be placed in places with scattered light. Keep the temperature from 18 ℃ to 20 ℃, light time not less than 12 hours, and take root in about 15 days. Outdoor cuttings in autumn should pay attention to shade, preferably covered with film. Made of 1 meter wide, length according to the number of cuttings, 0.5 meters high arch shed protection. Petunia can be moved to greenhouse for maintenance after rooting in the field.

VI. matters needing attention in cutting

The cutting ground can be in the place of astigmatism, and the best cutting temperature is 18 ℃-20 ℃. Attention should be paid to moisturizing, which can take root in about 2 weeks. 18 ℃-20 ℃ is the best, we should pay attention to moisturizing, generally about 2 weeks can take root.

The above is the petunia can be cut, petunia cutting propagation technology, petunia like warm and sunny environment, not resistant to frost, afraid of rain and waterlogging. The suitable temperature for its growth is 13-18 ℃, and the winter temperature is 4-10 ℃. If the temperature is lower than 4 ℃, the plant growth stops. It can withstand high temperature of more than 35 ℃ in summer. During the peak growth period in summer, sufficient water is needed, especially in the summer high temperature season, it should be watered in the morning and late to keep the basin soil moist.

Petunia is a kind of plant introduced from abroad in our country, which is widely cultivated in our country at present. Because of its high ornamental value, it is deeply loved by consumers. People like to plant it, but when planting, they need to have a certain understanding of its breeding technology, so as to ensure its growth.

Cutting method of Petunia (graphic)

Cutting substrate. Maintain water permeability with a mixture of cultivated soil, rotten leaf soil and sandy soil sold on the market, plus a little perlite.

Cutting flowerpots. Generally choose the flowerpot is not too large, 15-20 caliber flowerpot can.

Cuttings. Generally do not choose old branches, it is not easy to live. Choose sturdy and pest-free branches, cut off the stem near the bottom of the node, about 10 cm, the wound to dry, remove all the buds and fruits on the cuttings, and remove 2 / 3 leaves.

Cutting temperature. The best soil temperature is 18-20 ℃, pay attention to moisturizing. Pour the matrix into the flowerpot and make a hole with scissors, chopsticks or bamboo sticks. The hole is 2-3 cm deep and 6 cm apart.

Insert the cuttings into a small hole, and then compact the surrounding soil.

When it's all done, pour enough water and cover it with cling film. Indoor cuttings put the cuttings in a place where the sun scatters light. Remember not to lift the cling film.

The cuttings can take root in 15-20 days without wilting and decay, which indicates that the cuttings have survived. It can be transplanted into pot in 30 days. Petunia recovers slowly after transplantation, so attention should be paid to carrying as much soil as possible when potting.

Selection of cutting time of Petunia and its reasons

Petunia cutting is easy to survive, generally choose the time of cutting is spring and autumn, at this time the survival rate of cutting is high. The suitable temperature and dry air in spring and autumn can achieve the effect of constant temperature and more water through human factors. At this time, cutting can increase the survival rate through artificial efforts.

Growth habits of Petunia

1. Sunshine and temperature. Petunia, native to South America, is a long sunshine plant and likes warm environment, but it has strong adaptability to temperature. The suitable temperature for growth is 13-18 ℃, and the range of temperature difference is about-2 ℃-35 ℃. But if the temperature is lower than 4 ℃, the plant will stop growing.

2. Water and soil. Petunia needs sufficient water supply in the whole growth process, especially in the hot summer, the basin soil should be kept moist sooner or later. In the outdoor environment, we should beware of the harm of rain and waterlogging, especially in the rainy season, we should pay more attention to the control of water, excess water will lead to excessive growth of stems and leaves, long-term stagnant water will even make the roots rot, the most serious wilting and death of the whole plant. In soil selection, petunia should give priority to the use of slightly acidic sandy soil with fertile, loose and good drainage.

Petunia maintenance

1. After planting, after reasonable maintenance, petunia seedlings will grow day by day and eventually become a beautiful bouquet! The perfect bouquet is made by pruning, topping and picking the heart of the petunia. Nitrogen fertilizer should be used in the early stage, and phosphate fertilizer can be used in the later stage to make the flowers and seedlings stronger and bloom better. Petunia maintenance in summer should pay attention to: spray more water when the temperature is too high to maintain soil moisture. In winter, it is necessary to ensure that the petunia receives enough sunlight (the temperature is more than 5 ℃). The petunia has the ability to resist low temperature.

2, less watering, it is recommended to water at noon when the sun is sufficient, the amount of water is not too much, let the seedlings and flowers drink enough! The methods and precautions of Petunia florescence Management Petunia usually blossoms in early March when it turns warm. If the initial flower pattern is not good-looking, it can be cut off. When the flower head appears a lot at once, you can keep it and wait for it to blossom. Scientific fertilization should also be carried out during flowering, and it is still recommended that fertilization be carried out in a cycle of 10-12 days. Plenty of sunlight can greatly improve the quantity and quality of flowering. if there is a lack of sunlight, it is prone to malnutrition-the leaves turn yellow and soft, and the flowers are dim and small.

The cutting method of petunia is relatively simple, preparation needs to be done before cutting, and all tools need to be disinfected. Then choose an appropriate time for cutting. After cutting, we also need to strengthen its maintenance and management, so that it can survive well.
