Breeding method of melon

1. Sowing method

After the seeds are ripe, they are harvested, exposed to the sun, put into paper bags and stored in a dry place. It is better to sow seeds in spring every year.

2. Cutting or ramet propagation

The May of every year is the flowering season of Chrysanthemum morifolium. At this time, the lateral buds can be removed and the cuttings can be cut in the clean river sand. Some leaves can be properly removed to ensure sufficient water.

In fact, growing a pot of melon and leaf chrysanthemum is very simple! Melon leaf chrysanthemum can not only be used as an ornamental plant, but also has a strong purification effect on formaldehyde in the air. Put a pot of melon and leaf chrysanthemum at home to keep the air fresh all the time.

Culture methods of Chrysanthemum morifolium

Melon-leaf chrysanthemum is a perennial herb, which is generally cultivated for 1-2 years old flowers. The breeding methods of melon-leaf chrysanthemum are not suitable for all flower lovers. The cultivation of melon-leaf chrysanthemum should be based on their own actual culture situation, combined with the habits of melon-leaf chrysanthemum. Below, let's take a look at the habits and characteristics of melon-leaf chrysanthemum:

I. Culture methods of Chrysanthemum morifolium

Chrysanthemum morifolium is native to the Canary Islands in the Atlantic Ocean and is now widely cultivated in parks or courtyards all over China. Beautiful and colorful flowers and colors, it is a common bonsai flower and ornamental plant decorating the courtyard room.

Melon leaf chrysanthemum likes warm winter and no hot summer climate conditions, avoid dry air and hot sun exposure, but also have good light, in the bud period, if the daily light is less than 3 hours, it can not normally grow buds and blossom. In order to prevent the crown deviation, you can turn the direction of the potted flowers to 180 degrees.

Melon-leaf chrysanthemum requires loose, fertile, well-drained soil. Like a sunny and well-ventilated environment, but avoid direct sunlight. I like a cool and humid climate. Cool temperature and plenty of sunshine are the main conditions for its good growth. Like sandy loam rich in humus and well drained, avoid drought, afraid of stagnant water, suitable for neutral and slightly acidic soil. The flowering period is from December to April of the following year, and the flowering period is from 3mi to April.

II. Key points of conservation of melon and leaf chrysanthemum

Temperature: avoid heat, the suitable temperature for growth is 10-20 ℃, the temperature can be further lowered during the flowering period, in order to prolong the flowering period, the seedlings can withstand a low temperature of 1 ℃.

Lighting: the growing period should be placed in a greenhouse with good light, and after flowering, it should be moved indoors for appreciation, and at least 4 hours of light should be placed in front of the brightly lit south, west and east windows every day, so as to keep the flowers and colors bright and the plants strong. Spraying Zhuangtiling at the bud stage can make the buds strong, the petals enlarged, the flowers colorful, the fragrance strong and the florescence prolonged. In cultivation, we should often change the direction of the basin, so as to make the Corolla plant shape regular.

Watering: keep the potted soil slightly moist and water thoroughly. But avoid poor drainage.

Fertilization: apply thin fertilizer during the growing period, and be careful not to splash fertilizer on the foliage. Rinse in time after fertilization and spray new high-fat film to protect soil moisture. Stop fertilizing during flowering.

Soil: general soil is fine.

Reproduction: sowing and reproduction. Sowing in the pot from July to August, the suitable temperature for germination should be 20-25 ℃, and the seedlings should emerge in 10-20 days, and the corresponding size pot should be used gradually according to the seedling growth.

Control aphids and red spiders: the first is to maintain proper temperature and humidity and good ventilation. Secondly, it should be found in time at the initial stage of the disease, the plants with insect pests should be separated as early as possible, and a small amount of pesticides should be sprayed on the plants with insect pests.

For aphids and red spiders, it can be sprayed with 2000 times dimethoate diluent. Because red spiders generally occur on the back of the leaves, and aphids generally occur on the tender top of the chrysanthemum, spraying should focus on the back of the leaves and the top of the plant, and the front of the leaves should also be sprayed properly.

The propagation method of melon leaf chrysanthemum the reproduction of melon leaf chrysanthemum is mainly sowing. For double-petal varieties, cutting or split-plant propagation can also be used to prevent natural hybridization or quality degradation. Between May and June after flowering, lateral buds often appear in the axils of the basal leaves, which can be removed and cut in clean river sand. When inserting, the leaves can be properly thinned to reduce transpiration, pour enough water after insertion and shade and protect against the sun. If the mother plant does not have lateral buds, all the parts above lOcm of stem height can be cut off to promote the occurrence of lateral buds. > sowing method: sowing usually takes place in late July and can blossom during the Spring Festival. It takes about half a year from sowing to flowering. You can also determine the sowing time according to the time it takes. If New Year's Day uses flowers, you can choose to sow seeds in mid-late June. When the sunshine is long, the flower bud can occur earlier, but the stem is slender and the plant is smaller, which affects the overall ornamental effect. Early sowing will lead to luxuriant plants and large flowers, so the sowing date should not be delayed until after August. The sowing pot soil was composed of 1 garden soil, 2 rotten leaf soil and 2 rice chaff ash, plus a small amount of mature base fertilizer and calcium superphosphate. Sowing can be done in shallow pots or sowing boxes. Mix the seeds with a small amount of fine sand and sow in a shallow basin, paying attention to sowing evenly. After sowing, cover a layer of fine soil to the extent that there are no seeds. Do not spray water with a spray can after sowing to prevent the seeds from being exposed. Soak or spray can be chosen to make the basin soil completely wet. Cover the glass on the basin to keep it moist, but leave a little space on one side for ventilation. Then put the sowing pot under the shade, or on the cold bed or cold room on the shady side, pay attention to ventilation and maintain a low temperature. The optimum temperature for germination is 21 ℃, and the seedlings germinate in about one week. After emergence, gradually remove the shade and remove the glass, so that the seedlings are gradually exposed to sunlight, but they must be shaded at noon and can be fully illuminated two weeks later. In order to prolong the flowering period, it can be sowed every 10 days or so. Cuttage or split propagation: double-petal varieties are not easy to bear fruit, so they can be cut. 1Mel-June, cut the axillary buds from the root or after flowering as cuttings and insert them in the sand. About 20 Murray can take root in 30 days, and Bei Yu5 can blossom in 6 months. It can also be propagated by root buds.
