Culture methods and matters needing attention of New Guinea Impatiens

The reproduction of New Guinea impatiens can be divided into three methods: sowing, tissue culture and cutting. Sowing and propagation time-generally in March-April, timely harvest, sowing with picking. The optimum temperature for germination is 22 degrees.

The method of tissue culture propagation has been successful and large-scale production has been started. Because the self-pollination ability of New Guinea impatiens is poor and the cost of tissue culture is high, cutting method is often used to propagate.

The cutting season is suitable for spring, summer and early autumn, and can be propagated year-round in the greenhouse. The cuttings can be collected directly from the buds in the axils of the leaves for micro-cutting, and the propagation speed is quite fast; the current year's branches can also be cut into several segments, each with 2-3 nodes. The cutting substrate can be made of plain sand or vermiculite. In order to improve the rooting rate of cuttings, the cuttings were quickly dipped with abt rooting powder, and new roots were produced in 5-6 days. After 2 weeks, when the root length was 2-3 cm, the cuttings could be put on the pot.

The suitable temperature for the cultivation of New Guinea impatiens is 16-24 degrees. The normal growth will be affected if the temperature is lower than 15 degrees or higher than 32 degrees, and the light requirement is 30-50 lx. If the temperature is suitable, it can blossom every year. The management of New Guinea impatiens needs to be fine, and watering is based on the principle of "seeing dry and wet". The growth of thin fertilizer and water sprayed with secondary leaf fertilizer every 7-10 days or retted every half a month is more gratifying.

2-3 weeks after planting, when the seedling height reached 10-15 cm, the application of compound fertilizer 0.5g/l, a small amount of many times, too much nutrients, brown spots in leaves, fertilizer nitrogen content was controlled at 50-100mg/l. When the light is strong, the flowering is early and small, at this time, it is necessary to often pick the heart to accumulate nutrients to promote lateral branches and make the plant type more plump.

Temperature and light: new Guinea impatiens like warmth and sufficient light, do not tolerate cold, avoid hot sun exposure, the suitable temperature for growth is about 20 degrees Celsius, flowers will become smaller if the temperature is above 25 degrees Celsius, and relative humidity must be increased above 30 degrees Celsius so that the plant can continue to grow. When the temperature is relatively low, the plant growth stops, and when the temperature drops below 7 degrees Celsius, it will suffer frost damage.

Soil and humidity: like moisture, afraid of drought, avoid waterlogging. When the moisture is insufficient, it is easy to cause the phenomenon of falling flowers and leaves. It has strong adaptability to soil, and the pH value should be controlled between 5.5 and 6.5. Rotten leaf soil, vegetable garden soil and sand should be mixed with 5 ∶ 3 ∶ 2 to form loose, fertile and breathable sandy soil. The basin should not be too large. The basin soil should be dry and wet, and it should be watered until the bottom of the basin comes out of the water. waterlogging will rot the roots and branches and leaves will wither if it is too dry. The most important thing in family care is to maintain a constant air humidity, and it is advisable to spray water to the plant frequently.

Soil: new Guinea Impatiens has strong adaptability to soil, and the pH value should be controlled between 5.5 and 6.5. Rotten leaf soil, vegetable garden soil and sand should be mixed with 5 ∶ 3 ∶ 2 to form loose, fertile and breathable sandy soil.

Temperature: new Guinea impatiens prefer a warm environment, the suitable temperature for growth is 20-25 ℃, the flowers will become smaller if the temperature is more than 25 ℃, and the relative humidity must be increased if the temperature is over 30 ℃ to keep the plant growing. When the temperature is relatively low, the growth of New Guinea impatiens stops, and when the temperature drops below 7 ℃, it will suffer frost damage.

Illumination: new Guinea impatiens like plenty of sunshine, avoid scorching sun exposure, and should be properly shaded in summer. In winter, New Guinea Impatiens will be placed in an indoor light place to fully receive light.

Humidity: new Guinea impatiens like to be wet and afraid of drought, avoid waterlogging, and it is easy to cause fallen flowers and leaves when the moisture is insufficient. The basin soil should be dry and wet, and it should be watered until the bottom of the basin comes out of the water. waterlogging will rot the roots and branches and leaves will wither if it is too dry. The most important part of family maintenance is to maintain a certain air humidity, it is appropriate to often spray water to the plant.

Fertilization: new Guinea impatiens has a long flowering period and usually needs a lot of nutrients, so you can apply some nitrogen fertilizer appropriately at the seedling stage. During the growing period and flowering period, nitrogen, phosphorus and potassium compound fertilizer should be applied once from 10 to 15 days. Avoid single application of nitrogen fertilizer, otherwise there will be more leaves and less flowers. If you accidentally stick the fertilizer on the leaves during fertilization, you should spray water and wash it off in time.

Breeding methods of New Guinea Impatiens

The common propagation methods of New Guinea impatiens are sowing, tissue culture and cutting. The best time for sowing and reproduction is from March to April of each year. Because of the high cost of tissue culture propagation, cutting method is often used for propagation.

The cuttings of New Guinea impatiens can be carried out in spring, summer and autumn, and can be propagated throughout the year in the greenhouse. The cuttings can be directly collected from the buds in the axils of leaves for microcutting, and the propagation speed is quite fast.

New Guinea Impatiens can also cut the branches of the year into several segments, each with 2-3 nodes. The cutting substrate can be made of plain sand or vermiculite. In order to improve the rooting rate of cuttings, the cuttings were quickly dipped with ABT rooting powder, and the new roots were produced in 5-6 days. After 2 weeks, when the root length was 2-3cm, the cuttings could be put on the pot.
