Guinea impatiens breeding method, what fertilizer to apply, a few days to water a little more

1 Planting Generally sown in March and April in spring. It can be sown in a seedbed or directly in a garden flower bed. The seedlings grow quickly, and the seedlings should be planted in early June after one transplantation. If sowing is delayed, the seedlings will be potted and can bloom on the National Day.

2 Light and temperature Loves light and is shade-tolerant, and receives at least 4 hours of diffused sunlight every day. In summer, shade should be used to prevent excessive temperatures and sun exposure. The suitable growth temperature is 16-26, and the ambient temperature during the flowering period should be controlled above 10.

In winter, it is necessary to go into a greenhouse to prevent freezing.

3 Watering and fertilization After planting, irrigation should be carried out in time. Pay attention to watering during the growing season, keep the potting soil moist often, especially in summer, but not accumulate water and the soil is too wet for a long time. If there is a lot of rain, you should pay attention to drainage and waterlogging, otherwise the roots and stems are easy to rot.

Fertilization should be done frequently after planting, and special attention should be paid not to dry and wet. Summer cut.

Do not water wilted plants in the scorching sun. Especially during the flowering period, it should not be affected by drought, otherwise it is easy to drop flowers.

4 Flowering control If you want to delay flowering, you can sow seeds in early July. It is also possible to use the method of topping, and at the same time remove the early blooming flowers and buds, so that the plant continues to expand, and top dressing once every 15-20 days After September, more flower buds are formed, so that they bloom on the National Day.

The suitable temperature for the cultivation of New Guinea impatiens is 16-24 degrees. Temperatures below 15 degrees or above 32 degrees will affect normal growth, and light requirements are 3-50,000 lx. If the temperature is suitable, it can bloom annually.

The management of New Guinea impatiens requires meticulousness, and watering is based on the principle of "seeing dry and wet". Spraying leaf fertilizer every 7-10 days or applying thin fertilizer water every half month is more gratifying. 2-3 weeks after planting, when the seedling height reaches 10-15cm, apply compound fertilizer, a small amount of many times, too many nutrients, brown spots on the leaves, and the nitrogen content of the fertilizer is controlled at 50-100mg l.

When the light is strong, the flowering is early and small, and at this time, it is necessary to accumulate nutrients by frequent topping to promote the development of side branches and make the plant more plump.

New Guinea impatiens dew wet lacquer spot putrefaction.

Symptoms are mainly leaf and stem damage. Nearly round to irregular dark gray-brown to black-brown lesions are produced on the leaves, and the lesions are whorled due to different colors. The back of the leaf is light in color, and when the humidity is high, blister-like black spots grow under the leaf, arranged in a ring pattern, that is, the conidia and conidia of pathogenic bacteria.

Lesion size. Stem infection produces black, depressed spots. When the humidity is high, the diseased part gradually decays, causing the leaves to fall off.

The causative agent Myrothecium Roridum tode ex frIt is called the dew wet lacquer fungus, which is a semi-known fungus. The conidia are saucer-shaped, sessile, often clustered, diameter, green at first, later black lacquer-like, white-edged, without bristles, peduncle 10 12 l 2 ( m).

The conidia are cylindrical, rounded at the end, colorless to light olive, green to black when clumped, lacquer-like when dry, mostly 5-9x1-2 (m). In addition to harming impatiens, the fungus also infects hollyhock, cockscomb, wild goose, large rock paulow, evergreen, pearl orchid, pepper grass, cold water flower, Chaotian pepper, mallow, eggplant, tomato, lentils, soybean, hemp, sugar beet, etc.

Transmission route and pathogenic conditionsThe pathogen is a weak parasitic bacterium, which often invades from the wound. Excessive humidity contributes to the onset and epidemic of the disease.

Prevention and control methods (1) Careful maintenance, avoid excessive humidity or water on the plants, and increase ventilation and light transmission. (2) Remove the diseased plant in time to prevent its infection. (3) Mix with 3 parts of 43% formaldehyde and 1 part of water and then spray the soil surface with a film, uncover the film before sowing or 3 days before placement, and also use 70 parts of 70% dixone powder and 30 parts of fine soil to mix and sprinkle into the soil surface for soil disinfection.

When breeding New Guinea impatiens, you can choose sandy soil and humus soil with good drainage performance and fertile soil, New Guinea daffodils like light, and can be placed in a warm and ventilated environment during maintenance to improve the growth rate of plants, and you can also guess that the locust provides nutritionally balanced fertilizer and clean river water for New Guinea impatiens.

1. Soil selection

The germination and rooting ability of New Guinea impatiens is very strong, so choosing a suitable soil environment can accelerate the growth of plants, and the general selection of soil is to mix humus soil, garden soil, and sandy soil in a ratio of 5:3:2 to make loose, fertile and breathable culture soil.

2. Lighting conditions

As an ornamental flower, New Guinea impatiens have a certain demand for light during the growth period, but they should avoid direct exposure to scattered light, and the temperature exceeds 30, they need to spray water mist to reduce the temperature of the surrounding air, otherwise it will slow down the growth rate of the plant and affect the beauty of the flowers.

3. Reasonable fertilization

New Guinea impatiens have a long flowering period, so in the process of maintenance more nutrients are needed, the growth period and flowering period can be appropriately applied with nitrogen-containing phosphorus and potassium nutrients of compound fertilizer, but the concentration should not be too high, it is best to mix water into a low concentration of chemical fertilizer in proportion, so that the plant with sufficient nutrients will be more bright flowers and bright leaves.

4. Reasonable watering

New Guinea impatiens also have a greater need for water, and need to provide sufficient water for the plants to keep the soil moist during maintenance, watering can be carried out every morning, choose unpolluted river water, natural water or nutrient-rich pure water for watering.

Hello, the New Guinea impatiens are planted as follows: 1. The plants bloom during cuttings, and these flowers can cause gray mold. Second, the flowers formed in the early stage are often on the foliage, which reduces the ornamental effect.

3. Inconsistent flower bud development will lead to unconcentrated flowering time after plant formation. To remove the flower buds, the cuttings should be sprayed with Florel at a concentration of 250 ppm, which will prevent most of the varieties from forming flowers. Some varieties curl after spraying Florel, but this does not affect plant growth.

In addition, it is best to spray Florel immediately after topping, otherwise it will delay the flowering of the plant. Temperature and humidityNew Guinea impatiens prefer warm and humid environments, and the best potential is in 23 years, the temperature is greater than 26, and the leaves and flowers are significantly reduced. At a temperature of 17, the plant grows very slowly. The temperature in the plant is controlled by the temperature in the plant rather than the temperature of the greenhouse, which is more than the temperature of the air.

The lower the relative humidity of the air in the greenhouse, the lower the temperature inside the plant, the slower it grows and the later it blooms. By applying water vapor to the greenhouse and maintaining a high phase shed to the humidity, the growth of the plants can be accelerated. The study found that when the indoor relative humidity was greater than 75%, the difference between plant and air temperature was between 2 and 3.

The humidity of the air during the day is not important, as the light allows the plants to maintain a high temperature intensity and photoperiodThe flowering period of the New Guinea impatiens is not affected by the photoperiod, and they grow best in moderate lengths of light. However, light is an important factor in determining the number of flowers, and the longer the light, the more it blooms. Therefore, the number of flowers can be increased by increasing the amount of light in winter.

Light intensity flowers do not have a direct effect, as it affects the body temperature of the plant and thus the flowering. Substrates and containers with good drainage can reduce the occurrence of diseases. When the plant is too dense, flowering will be delayed.

Water and nutrientsNew Guinea impatiens love moisture, and excessive dryness will cause the plants to lose flowers and wilt. To maintain that when the pH is less than that, the plant will have a toxic reaction to trace elements. New Guinea impatiens are not tolerant to fertilizer and are prone to fertilizer damage.

If there are nutrients in the planting substrate, it will take some time before fertilization; If no nutrients are available, 100 ppm liquid fertilizer is applied first, followed by concentrations ranging from 100 ppm to 150 ppm. The time it takes for a planting plan to go from topping to flowering varies depending on the temperature and variety, but generally compact floret varieties bloom faster. Planted in 20 environmental conditions, from topping to the opening of the third flower for 12 to 14 weeks; At 23 o'clock, flowering can be as fast as 1 week; 16 2 weeks later.

At 20 o'clock, it takes about 4 weeks from budding to the first flower, 3 to 4 weeks at 23 o'clock, and 5 weeks at 17 o'clock.

Impatiens do not need to be watered every day, and should not be watered during the sowing period, and the potting soil should be watered thoroughly before sowing to keep it moist. During the growth period, it is necessary to keep watering more, the potting soil is moist but avoid water accumulation in the potting soil, and the watering interval is 4-6 days. The flowering period can appropriately increase the frequency of watering and fertilization, with an interval of 3 days, and the amount of watering should not be too much, so as to avoid water accumulation in potting soil.

Here's how:

1. How to water during the sowing period.

During the sowing period, because the impatiens seeds are particularly small, the seeds should not be watered after being sprinkled on the potting soil, otherwise it is easy to wash away the seeds.

The potting soil should be thoroughly watered and moistened before sowing.

2. How to water during the growth period.

During the growing season, keep watering more and the potting soil moist. But avoid ponding soil.

Watering should be done at an interval of 4-6 days. If the weather is dry and the water evaporates quickly, the watering interval can be reduced appropriately.

3. How to water during the flowering period.

The water and nutrient requirements of impatiens in the flowering period are higher than those in normal times, so the frequency of watering and fertilization can be appropriately increased.

It is advisable to water at an interval of 3 days during flowering and fertilize at an interval of 15-20 days.

The amount of water watered each time should not be too much, and it is necessary to avoid water accumulation in the potting soil, otherwise it is easy to rot the roots and cause the petals to fall.

It should be noted that the watering of impatiens should not be in full sunlight, otherwise it is easy to cause plant discomfort. Can be watered in the evening or in the morning.

Impatiens don't need to be watered every day except for the dry summer season, put down the kettle you picked up, it's better to sit down and appreciate the beauty of the flowers, the foil of the leaves.

Impatiens love sunlight, are afraid of moisture, are heat-resistant but not cold-resistant, and are suitable for growing in loose and fertile slightly acidic soil, but they are also barren and thin. Impatiens have strong adaptability, easy to survive transplantation, and grow rapidly.

It should be watered once a day during the growing season, twice a day in the hot summer, pay attention to drainage on rainy days, and in short, do not dry out or accumulate water in the potting soil.

It prefers a moist and cool environment, so it does not need to be watered every day, but as long as the surface of the soil is 5 minutes dry, it needs to be watered.

Impatiens do not like to be in moist soil. Impatiens love sunlight.

Pour it once every two days, absolutely.

If you forget your answer, we can use this optional email address to send you instructions for resetting your information.

It is not needed, although this plant is not drought tolerant, it is generally enough to water once every 1 2 days, but it does not need to be watered every day.

If the environment is very dry, then it needs to be watered every day, otherwise it will affect the quality of the impatiens, and the spring will also lead to no flowering.

Usually you can plant New Guinea impatiens by hydroponics, and it is best to cut off the branches on the robust plants when hydroponic New Guinea impatiens, and you can properly apply rooting powder to the bottom of the branches before hydroponic cultivation. New Guinea impatiens are light-loving plants, and it is best to plant them in a well-ventilated indoor environment with plenty of sunlight during hydroponics.

New Guinea impatiens, also known as multicolored impatiens, belongs to perennial evergreen herbaceous plants, and is a species with great ornamental value in impatiens. New Guinea impatiens can be grown hydroponically, and it is best to cut off diseased branches when hydropouring New Guinea impatiens.

After that, you need to remove all the leaves from the branches, leaving only two leaves at the top of the branches, so as to prevent the leaves from absorbing too much nutrients from the branches. If you want New Guinea impatiens to take root early, you can apply some rooting powder to the bottom of the branches before hydroponics, and it is best to choose clean and purified water during hydroponics.

New Guinea impatiens are light-loving plants, and it is best to place the plants in a ventilated and well-lit environment indoors during hydroponic play, and the plants should be properly shaded during the process. New Guinea impatiens do not have high nutrient requirements, but nitrogen fertilizer should be applied to the plants during hydroponics, and it is best to dilute the fertilizer with water before each fertilization.

New Guinea impatiens have strict requirements for water quality, and it is best to change the water for the plants every two days during hydroponics, and the amount of water should not cover the leaves each time to prevent leaf rot. New Guinea impatiens grow faster, and the leaves can germinate in about half a month when maintained, and then the branches and leaves of the plant should be properly pruned when planting.

There is no need to water it every day, and watering it every day is harmful to impatiens. Impatiens love sunlight, are afraid of moisture, and are heat-resistant but not cold-tolerant. Sun-loving terrain and loose, fertile soils can also grow in poorer soils.

Impatiens should not be watered during the sowing period, and the potting soil should be watered thoroughly before sowing to keep it moist. During the growing period, it is necessary to keep watering more, the potting soil is moist but avoid water accumulation in the potting soil, and it is advisable to slip and bend between watering for 4-6 days. The flowering period can appropriately increase the frequency of watering and fertilization, the interval of 3 days is appropriate, the amount of watering should not be too much, and the letter is stuffy to avoid potting soil water.
