Main points of sowing and propagation of lotus flower

The shape of the lotus is very unique, and it is also a common and popular crown dance in winter and spring, but because the lotus is native to intelligence, it likes the cold environment, and it is often difficult to cultivate it in high temperature areas. If friends who like buns want to breed themselves, they can choose the sowing method to breed.

Lotus flower

The sowing method of breeding purse flowers can be carried out from late August to September when the weather is cool, not too early. Warm and muggy weather is easy to cause seedlings to rot, and plants are smaller if sowing too late. The lotus seed is small, so don't sow it too densely. After sowing, cover a thin layer of fine sifted soil. After sowing, soak the basin in a water pan. After soaking the soil, cover the slide and move it to the shade. Seedlings can emerge in about a week. After emergence, remove the covering slides and put them in a ventilated and bright place. when the seedlings are too dense, the temperature should be reduced to 15 degrees, so that the seedlings can grow and thrive.

In keeping seeds, attention should be paid to the selection of excellent mother plants and artificial pollination. When the flowers are about to wither, the Corolla can be removed to avoid decay and affect fruiting. At the same time, nutrition concentration is conducive to the full development of seeds.

The management of lotus flower seedling stage must be meticulous. High temperature and too wet soil will cause seedling death. It is necessary to get rid of infected plants in time, spray Dyson zinc and keep the basin soil dry. In indoor cultivation, when the air is too dry, it is also prone to the harm of red spiders and aphids. Dimethoate can be sprayed and diluted 500 times, and water is sprinkled on the ground to increase air humidity.

The planting method of lotus flower

(1) Overview of lotus flower

Lotus flower, also known as Baobao flower, belongs to Scrophulariaceae perennial herbaceous potted flowers. It has short plants, peculiar flowers and bright colors. It is one of the excellent potted flowers decorated and beautified in winter and early spring. Its full bloom coincides with the Spring Festival and is used to decorate the family living room, dining room, study and bedroom, adding to the thick spring flavor of the festive festival.

(2) the main points of lotus cultivation.

Temperature: the suitable temperature for growth is 15 degrees Celsius, if the room temperature is higher than 20 degrees Celsius, it is disadvantageous to its growth, budding and flowering. When flowering, the temperature is kept at about 8 degrees Celsius, which can prolong the flowering time.

Light: the purse flower is a long-sunshine flower, which can blossom ahead of time by increasing the light.

Moisture: purse flowers avoid dampness. In the process of maintenance and management, watering must grasp the principle of "seeing the son and seeing the wet". When watering, we should pay attention not to make the water droplets gather on the leaf surface or bud, otherwise it will rot the heart and rot the leaf.

Air humidity: purse flowers like cool and humid environment, and good ventilation, when placed in the room, should pay attention to spray some water, increase indoor air humidity.

Fertilization: Lotus prefers fertilizer, applying organic thin liquid fertilizer every 7-10 days, or compound fertilizer several times, the concentration should not exceed 0. 5%. 3%.

Reproduction: sowing, stem insertion, sowing is better, sowing should be carried out in cool weather, not too early, prematurely because of high temperature, seedlings are easy to rot, it is usually appropriate to sow in mid-September.

New planting technology of lotus flower

Lotus flower, formerly known as Pu Baobao flower, Latin name: Calceolaria crenatiflora. Scrophulariaceae and Scrophulariaceae belong to perennial herbs, which are cultivated as annual flowers in the garden. There are fine hairs on the stems, branches and leaves of the whole plant, and the leaves are ovate and opposite. The flower shape is chic, the Corolla is two-lipped, the upper lip is erect and small, the lower lip is enlarged like a bump, the middle is empty, and the stigma is inserted between the two cysts. The variety of flowers and colors is rich, monochromatic varieties have different shades of flowers such as yellow, white and red, while complex colors are stained with orange, pink, brown and red spots on each background color.

The flower color is rich, the flower shape is unique, the flower diameter is 3cm to 4cm, the natural flowering period is from February to May, and the seeds mature after June. Like cool, warm air, well-ventilated environment, do more winter and spring potted plants for family interior decoration, can also decorate the conference hall, can also be used for celebration decoration and so on.

I. Propagation methods

(1) the sowing method should be carried out in a shallow basin in the first and middle of September. The best sowing soil should be 6 pieces of fully mature rotten leaf soil and 4 parts of river sand, and the soil should be disinfected. There is no need to cover the soil after sowing. Watering with soaking basin method, cover the basin with glass and newspaper, put it in the shade or cold bed, keep it 18: 20, 39: 10. After 1 week, the seedlings will emerge. After emergence, remove the glass and newspaper in time, and gradually see the light. When the seedlings are neat and the room temperature is on the high side, 1000 times solution of strychnine can be sprayed to prevent quenching disease. When the room temperature is low, 0.1% phosphate dioxygen can be sprayed to promote root seedling strength. 2. 3 true leaves were planted.

(2) in order to retain the characteristics of excellent varieties, stem insertion can also be used in the growing period.

Second, the main points of cultivation

(1) it is better to use sandy loam rich in humus, such as rotten leaf soil, garden back soil and fine sand at 3:2:2, and add a small amount of phosphorus bait fertilizer to mix.

(2) during the temperature growth period, it is suitable for the temperature to be controlled at about 20 ℃ in the day and 10 ℃ at night, and the flowering period can be prolonged when the temperature in the flowering stage is 5: 15 ℃.

(3) Water should be watered evenly and should not be too dry or too wet. Flowering to prevent rain, in addition to reasonable watering, but also often need to spray into the air, sprinkle water to the ground, but the soil moisture is not too large, and pay attention to ventilation. Watering, fertilization do not splash fertilizer on the leaves, especially purple flower varieties should pay more attention.

(4) fertilization from leaf extension to pre-flowering, 10%-15% rotten cake fertilizer shall be applied every 7-10 days; before flower bud formation, additional phosphate fertilizer such as bone powder or superphosphate should be applied once; during the peak growth period, about 40% rotten fertilizer water should be applied once a week. Generally, rinse with water immediately after fertilization, the leaves and buds should not be splashed with water.

(5) avoid strong light during the period of light growth, especially after June, cover the excessive sunlight, strengthen ventilation and pay attention to watering. The purse flower is a long-day plant, which promotes the development of flower buds and blossoms early under long-day light. In the north, if you want to make it blossom in New Year's Day or the Spring Festival, you can extend the daily light hours to 13-14 hours by lighting at night.

(6) Diseases and insect pests are prone to quenching disease in seedling stage, and it is easy to cause physiological diseases such as root and leaf rot under the condition of high temperature and multi-temperature. Pests include niece insects and red spiders that harm flower branches and leaves.

(7) at the initial stage of artificial pollination, the plants with excellent flower shape and color and strong seedlings are selected as the seed collection mother plant, and the flowering period is kept ventilated, properly dry, and placed in a slightly cool place; if the temperature is too high, it is easy to lead to poor fruiting. Artificial pollination should be isolated from other varieties. Due to the inconsistency of seed maturity, it is necessary to harvest along with ripening. After the harvested cucurbit fruit is dried in the shade, the seeds should not be exposed to the sun. It is appropriate to put them in a cool place to dry and store them in a ventilated and dry place.

III. Regulation of florescence

(1) to facilitate cultivation, if it is required to blossom at Christmas and New Year's Day, the seeds should be sown in the middle of August, the room temperature should be controlled at 18: 20 ℃ and sprout in about 7 days; the seedlings should be put into pot in the first half of September and keep 1O~15 ℃; in the first ten days of October, the temperature should be controlled at 15: 20 ℃; in the middle of November, the temperature should be controlled below 15 ℃, and the light should be 13-14 hours a day; in late November, the room temperature should be kept at 15: 18 ℃, which can bloom in late December.

(2) if the "May Day" flowering is required, the sowing date can be postponed to late October and the room temperature should be controlled at 15: 20 ℃; after the seedlings are divided in late November, the temperature will drop to 1O~13 ℃ to make it grow slowly; in the middle of December, the temperature will be kept at 15: 20 ℃, and the plant will be planted in different pots with the growth of the plant. In the middle and last ten days of March, if the bud is still small, it should be heated to about 15 ℃, and it can enter the early flowering stage in late April.
