Cultivation methods and nursing techniques of pansy

  There is also a name for pansy, because it looks like a butterfly dancing, the three colors are cool and humid, and the summer is hot. Here is a brief introduction to the cultivation methods and nursing techniques of Pansy.

Method for cultivation of pansy

In order to cultivate the tricolor, you must master the following points:

sowing:

Pansy is usually sown by the sowing method in early September. It is required that the soil in the seedbed or seeding pot must be well drained. After sowing, the soil is twice as much as the seed, and the water is poured in a fine watering can and placed in a well-lit area.

The germination temperature of Pansy is 18-21 °C, germination in the dark for 7-10 days, the growth temperature is 10-13 °C, and it blooms 14-15 weeks after sowing. If the temperature is too high during sowing, it will seriously affect the seed. The germination and growth of the seedlings result in a low seedling rate. Generally, two methods can be used to cool down: First, use germination chamber or artificial cooling to produce suitable germination temperature and humidity. After emergence, move to a nursery shed with good temperature and shade, and let the seedling grow normally. It is the use of high mountains to carry out alpine seedlings in the climatic conditions of the Yangtze River basin where the natural low temperature of 700 meters above sea level is required.

After the three-color sowing, the seeds can be covered with vermiculite, the soil temperature is 18-24 ° C, the medium is kept moist, and the radicle does not need to be illuminated before it grows out, generally 7-14 days can be emerged. The soil temperature of the pansy seedlings is 15-24 °C during the growth stage. The lower the temperature, the slower the plant growth and the stronger the plant. Allow the soil to dry before watering, but avoid the permanent wilting of the plants, which is conducive to the growth of the three-color roots. The soil pH was maintained at 5.5-5.8, and some n or potassium nitrate fertilizers were alternately applied.

transplant:

When the three-color cockroaches grow 4 true leaves, they should be transplanted in time. Before transplanting, it is necessary to pour enough water. When transplanting, it is necessary to carry a little soil. The time is best to choose to be carried out on cloudy days or in the evening.

When the plant grows to 3-4 true leaves, appropriate seedlings can be carried out to promote the plant to be robust. At this time, the root system can reach up to 5 cm. At this time, the temperature should be lowered to prevent steepness. The temperature should be controlled at 18 °C, and the light can be appropriately increased. It is not suitable to use chlormequat at the seedling stage. When the root system has formed a root ball, the seedling seedlings can be directly placed on the basin, often using small pots with a pot diameter of 10 cm. The well-drained culture soil is selected, which is especially important for the autumn and winter when it is cold and weak, otherwise it is not easy to dry and seriously affects the growth. The soil pH should be 5.8-6.2, and if it is greater than 6.5, the roots will be black and the base leaves will be yellow.

Colonization

In early November, when the true leaves grow to 8 pieces, they can be colonized. Before planting, it is necessary to loosen the garden soil and apply the base fertilizer; when planting, try to bring the soil of the roots as much as possible, and the plant spacing is 15 cm.

Pansy grows in the autumn and winter seasons, and it can be shaded in spring and summer. The growth temperature is 7-15 ° C, and the temperature will be purple when the temperature is too low for a long time. In the early autumn, it is best to fall below 20 °C to promote growth, while 15 °C or above is favorable for flowering, and below 15 °C will form a good plant type, but will prolong the growth period. In the summer, flowers above 30 °C become smaller and grow thinner. Watering should be carried out when the soil is dry. When the temperature is low and the light is weak, be careful when watering. Excessive moisture affects growth and is prone to long branches. When the temperature is high, it is necessary to prevent the water from drying out. When the plants are flowering, it is necessary to maintain sufficient water for the increase of flowers and the increase of the amount of flowers. On the other hand, in the 2-3 times of watering in the growing season, fertilization should be carried out once with fertilizer, the concentration is 100-150ppm, and the compound fertilizer containing calcium is mainly used. In the early stage, nitrogen fertilizer is the main factor, and the phosphate fertilizer can be increased near the flowering stage.

Pansy care skills

Extend the flowering method of pansy:

1. Use different sowing time. Pansy is generally flowered about 2 months after sowing, so it is planted in spring, flowering from June to September; sowing in summer, flowering from September to October; sowing in November and flowering from February to March in the second year. This will continue to bloom throughout the year.

2. Strengthen management. It is necessary to keep the soil slightly wet, apply 3 times of thin compound liquid fertilizer before flowering, and apply 0.2% potassium dihydrogen phosphate solution twice during the bud stage. After entering the winter, the plants must be moved into a sunny place to maintain the temperature. The temperature during the daytime does not exceed 12 degrees, and the temperature at night is not less than 7 degrees. On sunny days, the windows must be ventilated at noon.

Cultivation points:

Pansy prefers fertile, moist, well-drained soil. Like a cool environment, it is more resistant to cold and slightly resistant to half yin. It grows poorly in the hot, rainy summer and cannot be strong. If the light is insufficient, it will not bloom well.

(1) Temperature

After winter, the seedlings are still younger and should be moderately cold-proof.

(2) Lighting

Give plenty of light in winter.

(3) Water and fertilizer

Watered in winter. During the growing period, it is necessary to fertilize and weed, and stop fertilizing after flowering. In the cultivation, the water and fertilizer are sufficient, so that the flowers are large, the flowers are large, and the flowering period is long.

What should I pay attention to when curing the tri-color enamel in the room?

In indoor maintenance, if the temperature is too high, it will reduce the quality of the flowers. Therefore, you should choose to open the window at noon on sunny days to make the plants grow stronger and brighter. After the three-color scented flower, the residual flower should be cut off to reduce the nutrient loss to ensure the quality of the late flowering.

Cultivation and conservation method of pansy

Ornamental value:

The three-color sorghum plant is low and tidy, with early spring flowering and long flowering period. The flowers are bright, shaped like butterflies, and have a velvety texture. They are popular flowers. It should be used as a flower bed, a flower border, and a flower border. You can also enjoy potted plants.

Pansy is a funny garden flower. When the chill of the early spring has not faded, it will bloom with a small "grimace" that exaggerates, and smiles to welcome the spring of flowers.

If you carefully play the pattern on the petals, you will find yellow, white and blue colors, which are wonderfully matched on 5 petals, like a cat's face, or a clown's face, colorful and funny. It is very witty and quite like a colorful butterfly. It is a must, especially for children. "Jiaojiao grimace purple white and yellow, also likes to smile and smile. The debt has not yet returned to the spring, only two or three lines of rhyme." (Contemporary Zhao Changzhi), this modern poem can vividly portray the cute image of Pansy:

In Greek mythology, there is a legend about pansy: In the spring of the year, the gods play on the grass and discover many colorful and lovely leeks, which can not help but praise, but the venerable Venus does not agree, call Son Cupid, ask him who is more beautiful than flowers. The simple child blurted out: "Of course it is a cauliflower!". Venus, who was raging, picked up the whip and slammed the flowers. The original monochromatic cauliflower was seriously injured, and the flowing juice formed different colors. From then on, more colorful flowers were produced.

Pansy is also the national flower of Poland.

Cultivation and conservation method of pansy

Medicinal value:

Pansy leaves contain pansy. Flowers contain musk saponins, saponins, volatile oils, vitamins A, B, C and other ingredients. Whole grass can be used as medicine. Oral whole herb preparation can treat respiratory tract inflammation, increase the secretion of bronchial cavity, and make the mucus diluted for easy discharge. It can also stop cough, treat children with sputum, and promote the discharge of chloride ions in the urine. The leaves have a laxative function and their spicy ingredients can cause vomiting.

Medicinal notes are:

1 tricolor medlar 3 ~ 9 grams, decoction and honey, can cure cough.

2 fresh tri-color silk flowers, sputum juice coated with the affected area, can treat sputum (unbroken).
