The planting method of Impatiens

To breed and breed impatiens with seeds. 3Mel 9 is suitable for sowing, and April is the most suitable sowing, so that it can blossom in the first and middle of June, and the florescence can be maintained for more than two months.

1. Land selection and preparation: it is appropriate to use sunny, moist, fertile, loose and well-drained soil. Apply basic fertilizer and prepare the land for border, high border in the south and flat border in the north, with a width of 1.2m.

2. Sowing method: the seed is small and has a long life, and its germination rate still reaches 79.7% when stored at room temperature for 3 years. Live, March in the South and April in the North. Open a shallow trench with a row spacing of 35 cm, spread the seeds evenly into the ditch, cover the soil with a little suppression, and then water it. Keep the soil moist after sowing, and seedlings begin to emerge in about 5 days when the temperature is about 25 degrees Celsius. The seed consumption is 500g per 667 square meters.

3. The height of the seedlings is 5cm to 10cm, remove the small, delicate and overdense seedlings, and set the seedlings according to the distance of 20cm. Reasonable close planting can lead to high quality and high yield.

4. Raising seedlings: the seeds are sown on the culture soil, lightly covered with soil about 0.3 cm, and germinate after 5-6 days. 3-4 true leaves can be planted in flowerpots or flower beds with a distance of 30 cm.

5. Florescence control: if you want to postpone the florescence, you can sow seeds in early July. The method of heart-picking can also be used to remove early flowers and buds, so that the plant continues to expand, topdressing once every 15-20 days. More buds will be formed after September to make them blossom on National Day.

6. Ploughing and weeding: prevent weeds from competing for water after emergence, and loosen the soil and weed at the right time. Water in time in times of drought. Ploughing and weeding 2 or 3 times a year.

7. Topdressing: when the seedling height is 30cm to 40cm, the old leaves in the lower part of the stem can be removed, the top can be removed, and the branches can be promoted. At this time, every 667 square meters of cake fertilizer 40 kg, can be downstream ditch, fertilizer sprinkled into the ditch, covering soil, watering. Pay attention to drainage in the hot and rainy season.

If you are going to plant a balsam flower yourself, you must first understand the growth process of impatiens and the cultivation methods of impatiens. The growth process of impatiens goes through the following five steps: sowing, spring is the best sowing season, April; 10 days after sowing, the risk flower emerges and begins to grow the first pair of true leaves, and liquid fertilizer is applied every other week; entering the growth period, impatiens rapidly grow luxuriant leaves and begin to form buds; impatiens blossoms As a result, the seeds can be retained on 9-10, and the seeds should be picked in time, just as its flower saying "Don't touch me", the shell of impatiens will burst on its own when it is ripe, and the seeds will be popped out and propagated by themselves.

Impatiens has strong adaptability, easy to survive after transplantation and grows rapidly. The cultivation methods of impatiens are as follows: 1. Planting: generally sowing in March-April in spring, which can be sown in the seedbed or directly in the courtyard flower bed. 2, light and temperature: impatiens like light, shade-resistant, receive at least 4 hours of scattered sunlight every day, shade in summer, enter the greenhouse in winter to prevent freezing.

3. Watering and fertilization: after planting, it should be irrigated in time, fertilized frequently, and special attention should be paid not to dry or wet. Never water withered plants in the hot sun in summer. Especially in the flowering period, do not suffer from drought, otherwise it is easy to fall flowers. 4. Florescence control: if you want to postpone the florescence, you can sow seeds in early July. The method of heart-picking can also be used to remove early flowers and buds, so that the plant continues to expand, topdressing once every 15-20 days. More buds will be formed after September to make them blossom on National Day. At the same time, we should also pay attention to the prevention and control of diseases.

The planting method of Impatiens

Impatiens, also known as peach red, impatient, belongs to the impatiens family annual herbaceous flowers. Then let's take a look at the cultivation techniques of impatiens that we have carefully recommended for you. I hope it will be helpful to you.

Cultivation techniques of Impatiens balsamina

Impatiens, also known as peach red, impatient, belongs to the impatiens family annual herbaceous flowers. Plant height 30 cm to 80 cm, stem fleshy smooth, leaves solitary, lanceolate, serrate. The flowers are large and shaped like a vibrant Phoenix with upward head, foot and tail wings, from which the name impatiens comes from. But in the United States, impatiens has a very interesting English name, called "Touchmenot". It means "Don't touch me!" Indeed, the ripe impatiens fruit is like a miniature bomb, if gently touched, the fruit immediately "explodes" and pops up the seeds. Impatiens is a widely cultivated grass flower, with a variety of colors, such as purple, red, pink, rose, white, etc., there is a flower with several colors of complex flowers, petals have single and double petals, the flowering period is long, from June to late autumn, although its flowers are not rich and luxurious, but also elegant and elegant.

Impatiens originated in China and India, strong sex, strong adaptability, all kinds of soil can be planted, generally sowed with seeds in spring, seedling transplanting, after planting plant height of 10 cm to 20 cm, coring can promote branches to blossom, liquid fertilizer should be applied once or twice in the growing period.

Chinese folk have used impatiens petals to dye their nails since ancient times, so they are known as "henna". For example, Li Yuying, a geisha in the Tang Dynasty, was good at playing the pipa. She liked to dye her long fingernails red with impatiens petals. When playing, she half-covered her face with the pipa and gently plucked the strings with her bright red fingernails. The pipa emitted a beautiful rhythm like a mountain stream, and how many princes and grandsons were amazed. She called her playing "falling flowers and flowing water".

It is distributed in most parts of the country. Most of them are planted in the courtyard for ornamental use.

The roots of this plant (impatiens root), flowers (impatiens), seeds (impatiens), etc., are also used for medicinal purposes. The dry stem is one of the medicinal materials of Tougu, which is detailed.

Biological characteristics of Impatiens balsamina

Impatiens family annual, biennial or perennial flowers, stems smooth, crisp and succulent, nodes often dilated, without stipules, generally alternate and opposite, upper leaves often whorled, glands between petioles, flowers bisexual, left and right symmetrical, solitary in leaf axils or slightly clustered, sepals 3, sparse 5, lateral 2 small, green, lower one large, petal-shaped, saccate, extending downward into a spur; petals 5, or because of 2 pairs of 3 unequal. The capsule is 5-valved when ripe, and the flap rotates spirally to eject the seed. Ho's impatiens: semi-shrub, with red stripes on branches, alternate leaves, ovate to ovate-lanceolate, long petiole, crenate margin, and a bristle between teeth. Flowers solitary or 2 clustered in axils of leaves, sepals 3, lateral sepals small, scalelike, petals 5, wing petals 2-parted, spur slender and curved, ca. 3.5 cm.

Propagation and cultivation of Impatiens balsamina

Sowing and cutting propagation can be done. Sowing can be carried out in all four seasons, and it can be sowed or sowed on demand. 128hole trays are used for sowing, and the suitable sowing temperature is about 20 ℃, and seedlings emerge in about one week. Cuttage can also be carried out throughout the year, select strong branches, cut off about 8 cm as cuttings, keep the temperature 20 ℃, about 20 days to root, summer water cutting is also easy to root. When the seeding seedlings are 5 cm high, they are transplanted for the first time, moved in a nutrition bowl of 8 cm, and planted in a basin of 15 cm at about 12 cm. The soil is mixed with peat soil 2, vermiculite or river sand 1 and slag 1, and an appropriate amount of sheep dung can be added as base fertilizer. For individual species and varieties with poor branching, such as New Guinea impatiens, they should be pinched properly at seedling stage. High temperature drying will make the impatiens leaves thicker and not stretch, the internodes become shorter, and when the plant shape is seriously affected, it will stop growing, so it is necessary to keep the environment cool and shade properly over the summer, the strong sunlight will burn the leaves, and if the light is too weak, the plants will grow too much, the leaves will become thinner and the leaves will be light green. In order to use flowers for the "National Day", in addition to choosing more heat-resistant varieties, you can also sow seeds in June and put the seedlings in the mountains about 800 meters above sea level in July and August to spend the summer. Impatiens need plenty of light in winter and spring, so they don't need shade. During the growth period to ensure the supply of water, especially in summer watering should be timely and adequate, keep the basin soil moist but not stagnant water, basin soil dry plants are very easy to wilt, when wilting, watering is easy to cause rot. Stagnant water is apt to rot. Maintain a certain amount of air humidity throughout the growing season, and spray water to the leaves and the ground in summer to increase air humidity. In order to control plant height and plant shape, in addition to applying more nitrogen fertilizer in the early stage, the application of nitrogen fertilizer should be controlled before and after flowering.

Diseases and insect pests of impatiens and its control

① cataplexy

It mainly harms the young stem. At the beginning, the base of the young stem shows water-stained spots, and then the disease spots become light brown to brown and constricted. The disease rapidly developed around the young stem, causing the seedlings to lodge and die from the base of the stem in the case of emerald green leaves. Finally rot or dry up. The disease is mainly caused by Rhizoctonia solani. The pathogen overwinters in the soil or on the diseased body, and spreads through water droplet splashing and seeds. Prevention and control: disinfect the soil before sowing; sow not too closely; control watering after emergence to keep the soil slightly dry; strengthen the ventilation of the environment; avoid continuous cropping. Taking medicine in time after the onset of the disease, 75% chlorothalonil 600 times, 50% carbendazim 500 times, and 40% carbendazim 200 times 400 times, spray once a week, in addition to the stems and leaves of the pot plant, should also be sprayed to the surrounding ground.

② powder mildew

It mainly harms the leaves. At the initial stage of the disease, there are small white powdery patches on the leaf surface, and then the leaves are covered with white powder layers. in early autumn, yellow dots appear in the white powder layers. finally, the dots become dark brown and the diseased leaves are withered and yellow. In severe cases, it can spread to the stem, bud and capsule, and there is also a white powder layer on it, and eventually the bud and capsule stop growing and wither. The pathogen of the disease is powdery mildew with monofilament shell of Xanthium sibiricum, which belongs to fungi. the pathogen overwinters on the disease residue and seeds and spreads by wind and water. The cultivation management should be strengthened, the environment should be transparent, less nitrogen fertilizer should be applied, potassium fertilizer and calcium should be increased, and diseased leaves should be removed in time. Once the disease occurs, medicine should be used in time, and 1000 times of 15% strychnine or 1000 times of methyl topiramate can be sprayed.

③ blight

It mainly occurs on the plant after seedling planting, harming the stem and root. At first, the tender stem or the base of the stem appears water-stained dark green to light yellow plaque, and then develops into black-brown rot, and the disease spot surrounds the stem, which makes the plant fall down from the diseased part. White silk-like material can sometimes be seen in the diseased part, that is, the bacteria of the pathogen. The disease is caused by Phytophthora, which often overwinters in the soil with the disease residue and spreads through soil and water spatter and wind. Prevention and control: give priority to prevention, one is soil disinfection, the other is to improve the cultivation environment. Drug prevention and treatment should be timely, the available drugs are 80% aluminum ethyl phosphate 500 times, 25% metalaxyl 500 times 800 times, 1% Bordeaux solution, 0.1% 0.2% copper sulfate solution.

④ mosaic disease

It mainly harms the leaves, there are two kinds of symptoms after the leaves are infected, one is that the leaves become smaller, wrinkle, the leaf edge is twisted, the leaves have dark green and yellow and white spots, the old leaves are yellowed, the flowers are small and atrophied, the petals are brocade-shaped, and the plants are short in severe cases. Second, the chlorosis of the leaf veins is gray and translucent, and then the chlorosis is mottled and clustered, and the leaf margin is slightly curled. The main pathogens of the disease are turnip mosaic virus and cauliflower mosaic virus. It is transmitted by juices and a variety of aphids. Prevention and control: strengthen cultivation management, maintain environmental hygiene, remove diseased plants in time, and reduce human transmission in the course of operation. Insecticides can be used to control virus-transmitting insects.

White silk disease of ⑤

It is caused by Sclerotinia sclerotiorum in the fungus. For symptoms and prevention, see Orchid. Impatiens blossoms all the year round, with many flowers and colorful flowers, and the plant is highly suitable. It can decorate the family and the meeting hall, or it can be placed in the open air to make a big flower bed.
