Cultivation techniques of single anther in Jinmai

Matrix

Potted soil can choose rotten leaf soil, vegetable garden soil, river sand, add a small amount of cake fertilizer as base fertilizer, and perlite, peat soil and frogstone can be used as cultivation substrate at the proportion of 12211.

Fertilizer and water

Fertilization should be based on the principle of "applying thin fertilizer frequently". During the growth period, dilute liquid fertilizer was applied once or twice a month, or diluted MS nutrient solution was applied. Stop fertilizing in winter, pay attention to avoid the stems and leaves of the plant when fertilizing, so as to avoid fertilizer damage. It is necessary to keep the basin soil moist in the growing season and spray water to the leaves once or twice a day in summer. if the basin soil is short of water, the basal leaves are easy to dry up and cause fallen leaves. Watering should be properly controlled in winter to increase the cold resistance of the plant.

Light

The golden vein single flower grows well under the bright scattered light and avoids the scorching sun, so it should be placed in a semi-shaded and humid environment when it is hot in summer, especially around noon. Excessive strong light is easy to make the striped color on the leaves fade, affecting the ornamental effect, but the lack of light is very easy to cause overgrowth and leaf color darkening, affecting the normal flowering of the plant. In addition, during maintenance, we should also pay attention to proper ventilation to prevent fallen leaves and affect the ornamental effect.

Temperature

The suitable growth temperature of Jinmai single flower is 20 C ~ 25 C. it likes the warm and humid climate, and the room temperature in winter should not be lower than 10 C. Pay attention to ventilation and cooling in summer. Higher than 30 C will cause damage to the leaves.

2. Ecological habits

Jinmai single anther likes warm, humid and semi-overcast environment, warm and humid climate, like light, slightly resistant to shade, not resistant to cold, avoid stagnant water, avoid direct sunlight, and should be placed in semi-shade in summer.

The single flower of Jinmai is not cold-resistant, the suitable temperature for growth is 20-25 ℃, the overwintering temperature must be above 10 ℃, and the fertile soil with good drainage is suitable.

Only the top teeth can form flower buds and blossom, the winter temperature is not lower than 15 ℃, and the loose and fertile rotten leaf soil is better.

Cultivation techniques of single anther flower of Jinmai

The single flower of Jinmai (zebra flower) is native to tropical and subtropical regions of South America. Like warm, moist semi-shady environment, not cold-resistant, afraid of drought, although like sufficient sunshine, but also afraid of strong direct sunlight, can be placed in bright light without direct sunlight maintenance.

1. Lighting

Usually indoor training can be placed in front of the south-facing window with plenty of light. In summer, we should pay attention to proper shading around noon to avoid strong direct sunlight.

2. Temperature

The most suitable temperature for growth is 20-25 ℃. Flower buds can only be formed when the air temperature is above 20 ℃. In winter, the room temperature should not be lower than 10 ℃. If the room temperature is too low, it is easy to suffer frost damage, and even cause leaves to fall off.

3. Fertilizer

From early summer to early autumn, during the period from flower bud differentiation to pregnant bud, compound liquid fertilizer can be applied every half a month to promote its healthy growth, green leaves and flowers.

4. Moisture

Because of its large leaf area, zebra flower applies mature thin liquid fertilizer or compound fertilizer every 10 days or so. Keep it in a brightly lit room in winter, reduce watering appropriately, and keep room temperature above 10 ℃. If there is heating in the room, you can spray the plant with water close to room temperature, so as not to affect plant growth due to air dryness. After flowering, the plant has a dormant period of 4 to 6 weeks, it is appropriate to control watering, stop fertilization, such as too much watering is easy to cause rotten roots and leaves. A basin change is carried out at the end of the dormant period, and the basin soil is required to be rich in humus and have good air permeability.

5. Soil

Potted soil is required to be rich in humus and good air permeability. It can be mixed with rotten leaf soil or peat soil and vermiculite or perlite. After changing the pot, put the plant in a warm semi-shade, keep the soil and air moist, and wait for new branches to sprout.

6. Pruning

Since zebra flowers rarely grow from lateral branches, they can be pruned or pruned in cultivation to control plant height, maintain beautiful plant shape, and promote lateral buds to achieve the purpose of more flowering. The residual flowers should be cut off in time after the flower fade, so as not to consume too much nutrients and affect the plant growth.

Culture method of single anther flower of Jinmai

1. Potted plants

The culture soil can be mixed with 4 parts of rotten leaf soil, 4 parts of garden soil and 2 parts of river sand. During the growth period, the dilute liquid fertilizer combined with chlorine and phosphorus is usually applied once every two weeks, and the basin soil should be kept moist at the same time. Watering should be controlled when the room temperature is low in winter, and it is appropriate to keep the basin soil slightly moist. Jinmai single flower is a kind of light-loving flowers and trees, it should be placed in the outdoor semi-shady place in spring and autumn, near the south windowsill in summer and winter, and pay attention to ventilation. If put in the lack of light for a long time, it is easy to cause futility, and the leaf color is lack of luster. Change the basin once a year in early spring, combined with the basin for pruning and shaping to control the height of the plant.

Change pots after flowering every spring or autumn. Jinmai single flower is a kind of light-loving plant in foliage plants, which is usually maintained in a place with sufficient light, and shade should be carried out during outdoor maintenance in summer to avoid scorching leaves; when the light is too weak, it is easy to lead to elongation of internodes and dull leaf color. During the growing period, we should strengthen watering to keep the basin soil moist, and often spray water to the leaf surface and the surrounding environment, such as dry and lack of water, cause fallen leaves, cause stem disjoint and reduce the ornamental price; avoid basin soil stagnant water. In order to avoid causing root rot; reduce watering in winter to keep the basin soil slightly dry. To enhance cold resistance. During the growing period, thin liquid fertilizer or compound fertilizer particles should be applied every half a month, and try not to make the fertilizer contact with the stems and leaves, and stop fertilizing in winter. Because of its weak self-branching ability, the growing period should be pruned or coring regularly to depress the plant height and promote multiple lateral branches. Keep the plant plump. Move to the room at the end of autumn, the temperature should be above 10 ℃.

2. Soil

Planting soil can be mixed with garden soil and rotten leaf soil in the same amount, plus a little river sand to facilitate drainage, pruning and changing pots in spring combined with cutting. Often keep the soil moist during the growth period, apply compound granular fertilizer with a nitrogen, phosphorus and potassium content of 1:1:1 once a month, and apply it at the edge of the basin to keep the fertilizer from touching the stems and leaves. During the growing period, the soil should be fully watered to prevent the soil from drying and cracking. Fertilize once every ten days, apply more phosphorus and potassium fertilizer, less nitrogen fertilizer, apply at the edge of the basin, do not make fertilizer contact with stems and leaves. It is better to scatter light, put semi-shade in summer basin, excessive sunshine, easy to scorch the leaves. It is necessary to prune or pick the heart regularly to depress the plant height and promote more branches and flowering. The foliar surface sprays more water in summer, drier in winter, and more sunshine.

3. Disease

Prevention and control of muggy weather is vulnerable to shell insects, red spiders and other harm, mostly concentrated in the petiole and the back of the leaves, need to strengthen ventilation, and timely spray 1000-1500 times of omethoate EC for prevention and control.

The Propagation Mode of Jinmai monoanther Flower

Cuttings are usually used for propagation, and the cutting time is 5-6 months or after flowering. Select robust branches, cut off the top tip or stem segment with 3-4 nodes as cuttings, remove 1 / 3-1 / 2 of the lower leaves and upper leaves, and insert them into the wet sand bed. Avoid the river sand too wet, so as not to rot the cuttings. The suitable temperature for rooting is 20-25`C moisturizing and shading. It can take root in about one month and can be transplanted after the new leaves grow.

The best cuttage is from May to June or after flowering. It can take root in more than a month. It can be transplanted after the new leaves grow.

Planting soil can be mixed with garden soil and rotten leaf soil in the same amount, plus a little river sand to facilitate drainage, pruning and changing pots in spring combined with cutting. Often keep the soil moist during the growth period, apply compound granular fertilizer with a nitrogen, phosphorus and potassium content of 1:1:1 once a month, and apply it at the edge of the basin to keep the fertilizer from touching the stems and leaves. During the growing period, the soil should be fully watered to prevent the soil from drying and cracking. Fertilize once every ten days, apply more phosphorus and potassium fertilizer, less nitrogen fertilizer, apply at the edge of the basin, do not make fertilizer contact with stems and leaves. It is better to scatter light, put semi-shade in summer basin, excessive sunshine, easy to scorch the leaves. It is necessary to prune or pick the heart regularly to depress the plant height and promote more branches and flowering. The foliar surface sprays more water in summer, drier in winter, and more sunshine.

The routine propagation of zebra flower can be done by cutting the stem with leaves in early summer, or by cutting with root buds or root buds in winter and spring to keep the soil moist and high air humidity after cutting. it is easy to take root under the condition of 25 ℃. If the temperature is not suitable, the germination ability is not strong, and the reproduction rate is low.

The technique of test tube culture can also be used for propagation, and the effect is better. The specific method is as follows: the buds on the vigorous growing plants are routinely sterilized with 0.1% mercury and inoculated in the Ms medium, which is supplemented with cytokinin 6--BA1.0--2.0 mg / L and auxin IBA 0.4 mg / L. The way of proliferation is the differentiation of buds or calli into seedlings. After growing into a tender shoot of about 2 cm, it can be transferred to the rooting medium of 1/2MS+IBA0.5--1.0 mg / L, and it can take root after about 40 days. In a year, except for the summer high temperature season, all can be transplanted, and the survival rate is more than 90%. The matrix should be loose fine sand, perlite, vermiculite and so on. The seedlings that survived by transplanting grow faster and can meet the requirements of commercial potted flowers in about half a year. During maintenance, attention should be paid to keeping the leaf surface clean, otherwise it is easy to be infected with leaf spot disease, resulting in leaf shedding and affecting the ornamental effect. For the defoliated plants, it can be made up by retraction pruning to promote the germination of new buds at the base.
