How to raise seedlings of melon leaf chrysanthemum? How to plant melon leaf chrysanthemum seeds

The melon leaf chrysanthemum in the green flower garden, do you know what are its breeding skills?

The planting time of melon leaf chrysanthemum seeds is in August, the selected soil can be red soil, the fine sand and seeds are mixed and sprinkled on the soil, and the shade treatment is done in summer, and the growth temperature is controlled between 18 and 22; At the beginning, the seeds do not need any water and fertilizer, and they can bloom in February of the following year after careful care.

The flowers of the melon leaf chrysanthemum are very beautiful, so how to plant the seeds of the melon leaf chrysanthemum, its planting time is generally in August, and the sowing time too early will make it difficult for the seedlings to withstand the high temperature in summer; The soil chosen can be red soil, which has sufficient nutrients and is also conducive to seed absorption.

Choose round and plump seeds, stir them well with fine sand, and then sprinkle them in the soil, covering them with 3 mm thick fine soil to ensure that the water in the soil is not evaporated; The planting period is summer, so it is necessary to do a good job of shading and avoiding direct sunlight.

The most suitable temperature for the growth environment of melon leaf chrysanthemum seeds is between 18 and 22, and put it in a cool place for maintenance, the indoor finger key temperature is too high will cause the seeds to be hot and rotten, and the low indoor temperature will make the seeds in the dormant period and unable to grow normally; To keep the temperature constant.

At the beginning, when the seeds have not yet germinated, they do not need any water and fertilizer, but only need to ensure that the soil is slightly moist; 15 After 30 days, the seeds begin to germinate, and when a leaf grows, you can use diluted nitrogen fertilizer, once a month, the number of watering should not be too frequent, once a week, and wait until February of the following year, you can bloom normally.

Melon leaf chrysanthemum is a perennial herbaceous value of Asteraceae, the whole plant is densely pubescent, the leaves are every three pieces of a round, into a triangular locust bend, the leaves are like cucumber leaves, so the name is melon leaf chrysanthemum. Its flowers are gorgeous, rich in color, and have blue flowers that are very rare indoors; And the flowering period is long, about 6 months of flowering time, is the New Year's Day, Spring Festival, "May Day" Labor Day and other festivals of the ideal potted flowers, is the representative flower of winter and spring. However, it is not easy to cultivate potted flowers with good plant shape, beautiful leaf color and long flowering, and the following key technical measures in the cultivation process of melon leaf chrysanthemum must be mastered.

The sowing box should be placed under the shade of the canopy, or under the shade of a tree; If you are using furrow sowing, you must build a shade shed above the soil to reduce the radiant heat of the sun.

Seedling water control: mainly by spraying water mist to reduce the temperature of the seedbed and supply seedlings with water. The principle of spraying is that it is enough to spray wet, and the seedbed soil cannot be too dry, nor can the seedbed soil be too wet.

It is difficult to recover after the seedlings wilt too dry, and the seedlings are in the high temperature period when they are too wet, which is easy to sit, resulting in a low survival rate of the seedlings.

Preparation of culture soil: melon leaf chrysanthemum prefers well-drained sandy soil rich in humus, and the pH is 6 5-7 5. When preparing the culture soil for sowing, it is necessary to pay attention to the unpolluted humus soil or personal ash, pure loess and fine sand according to 3:

After 1:1 mixing, sieve and no more fertilizer is put in, so that the prepared culture soil is conducive to seed germination and growth. The overly sticky culture soil cannot withstand drying, and once it is slightly dry and cracked, it will break the fibrous roots of the seedlings, which will lead to the death of the seedlings and reduce the slaughter to life.

The culture soil after seedling division can be the same as the culture soil used for sowing, and the seedlings can be strengthened. When potting, evenly put bean cake, bone meal or superphosphate as the base fertilizer in the culture soil, or use manure, fire soil ash, garden soil, vegetable cake, fine sand, press 3:2:

The ratio of 2:1:1 is used to prepare the culture soil to ensure the sufficiency of plant nutrients**.

The manure must be dried after being cooked and rotted, and the vegetable cake must be crushed and fully stirred and mixed before being sieved before it can be used as a culture soil for planting.

Pay attention to temperature control: melon leaf chrysanthemum likes cool climate, avoid cold in winter, and avoid high temperature in summer. Therefore, in winter, it is necessary to use greenhouse cultivation, which is generally maintained at more than 10 degrees Celsius, and often kept at room temperature of about 15 degrees Celsius in order to grow well; In the summer, the planting box should be placed under the shade shed, or the planting furrow should be opened under the shade shed, and at 10 a.m

before 00 or in the afternoon; Watering after 5:00 is more appropriate, do not water at noon, so that the seedlings can smoothly pass the high temperature period.

Pay attention to control humidity in winter: melon leaf chrysanthemum has high humidity requirements in order to grow well. How to make the humidity moderate in winter is the key to the success of the cultivation of melon leaf chrysanthemum.

Too dry, easy to make the leaves of melon leaf chrysanthemum often in a wilted state, is not conducive to leaf growth, easy to make the leaves yellow, but also easy to produce red spiders and aphids. Too much watering, too high indoor humidity, easy to rot roots, main stems, leaves, but also easy to produce aphids; If the room temperature is too high and the ventilation is not good, it is easy to produce powdery mildew.

Seeding propagation is the main propagation method of melon leaf chrysanthemum. It takes about half a year from sowing to flowering. Sowing is carried out in late July, and flowering is possible in spring.

It is also possible to determine the sowing time according to the time of use. If the flowers are used on New Year's Day, they can be sown in mid to late June. The earlier the planting, the more lush the plants will be, and the more beautiful the flowers will be.

The planting time should not exceed September at the latest. 1 part garden soil, 2 parts humus soil, 2 parts chaff ash, add a small amount of superphosphate and decomposed base fertilizer to mix into sowing potting soil. When sowing, you can use a wooden box or a shallow pot.

Mix the seeds with a small amount of fine sand and spread them evenly in a wooden box. It is better to be covered with a layer of fine soil, and the seeds are not visible. The potting soil can be moistened by spraying or soaking the pot while avoiding exposing the seeds.

In order to keep it moist, it is recommended to cover the basin with a layer of glass, but at the same time, pay attention to ventilation and leave a slight gap on one side.

Place the seeding pot in a cold room or under a shaded canopy where no sunlight is visible, and it is best to maintain the temperature at 21 degrees Celsius while paying attention to ventilation. About 1 week or so the seedlings germinate, and the shade on it is gradually removed so that the seedlings can be exposed to sunlight. However, when the sun is strong at noon, it is still necessary to pay attention to shading, and the imitation key can be completely fully illuminated two weeks after germination and emergence.

In order to prevent the quality degradation or natural hybridization of double-petaled seeds (flowers with multiple petals), propagation can be carried out by cuttings or divides. Most of the double-petaled varieties can be used for cuttings. From January to June, cut the root buds of melon leaf chrysanthemum or the side buds that grow after flowering and insert them into the sand for cuttings propagation or branch propagation.

It takes about 20 to 30 days to take root, and it can bloom after 5 to 6 months.

Melon leaf chrysanthemum is a perennial herb, generally do 1-2 years of flower breeding, melon leaf chrysanthemum breeding method is not applicable to all flower friends, breeding melon leaf chrysanthemum should be based on their actual breeding situation, combined with the habits of melon leaf chrysanthemum to breed, let's take a look at the habits and characteristics of melon leaf chrysanthemum:

First, the cultivation method of melon leaf chrysanthemum

Guara chrysanthemum is native to Canary Island in the Atlantic Ocean, and is currently widely cultivated in parks or courtyards across China. The flowers are beautiful and bright, with a variety of colors, and are a common bonsai flower and ornamental plant that decorates the courtyard room.

Melon leaf chrysanthemum likes warm winter, no scorching climate conditions in summer, avoid dry air and scorching sun exposure, but also have good light, in the bud breeding period such as less than 3 hours of light per day, can not be normal bud flowering. In order to prevent the crown from being deviated, the potted flowers can be placed in a 180-degree direction.

Guarana requires loose, fertile, well-drained soil. Prefer a sunny and well-ventilated environment, but avoid direct sunlight. Prefer cool, moist climates.

Cool temperatures and plenty of sunlight are the main conditions for its good growth. It likes sandy loam soil rich in humus and good drainage, avoids drought, is afraid of stagnant water, and is suitable for neutral and slightly acidic soil. The flowering period is from December to April of the following year, and the peak flowering period is from March to April.

Second, the maintenance points of melon leaf chrysanthemum

Temperature: avoid heat, the appropriate temperature for growth is 10-20, and the temperature can be lowered during the flowering period to prolong the flowering period, and the seedlings can withstand the low temperature of 1.

Light: During the growth period, it should be placed in a greenhouse with good light, and after flowering, it should be placed indoors to enjoy, and it should be placed in front of the brightly lit south, west and east windows for at least 4 hours of light every day to keep the flowers bright and the plants robust. Spraying flowers at the bud stage can promote strong flower buds, hypertrophic petals, bright flower color, strong flower fragrance and prolonged flowering period.

In cultivation, it is necessary to pay attention to changing the direction of the pot frequently to make the corolla plant shape regular.

Watering: Keep the potting soil slightly moist and watering thoroughly. However, avoid poor drainage.

Fertilization: Apply thin fertilizer during the growth period, and pay attention not to splash the fertilizer on the leaf surface, rinse it in time after fertilization, and spray a new high-fat film to protect fertilizer and moisture. Stop fertilizing during the flowering period.

Soil: General soil is sufficient.

Propagation: Seeding and propagation. Sow in pots in July and August, require germination temperature of 20-25, 10-20 days of seedlings, depending on the growth of seedlings gradually change to the corresponding size of pots.

Control of aphids and red spiders: The first step is to maintain proper temperature and humidity and maintain good ventilation. Secondly, in the early stage of the disease, it is necessary to find it in time, separate the pest plants as soon as possible, and spray a small amount of pesticides on the pest plants.

For aphids and red spiders, it can be sprayed with 2000 times dilution solution. Because red spiders generally occur on the back of leaves, and aphids generally occur on the top of the young and tender melon leaf chrysanthemum, the spraying should focus on the back of the leaf and the top of the plant, and the front of the leaf Zhengshi hole should also be sprayed appropriately.

Melon leaf chrysanthemum can be sown in stages, and those that require flowering on New Year's Day should be sown in early June of the first year; It is required that the spring flowering should be sown in August of the first year; Those who require May Day flowering should be sown in October of the first year, and those without flowering requirements should be sown in April and May. The sowing soil is made of humus and fine sand. After the potting soil is soaked, the seeds are evenly sprinkled into the soil surface, slightly covered with fine soil, to see the seeds as the degree, cover the glass after sowing, keep the potting soil moist, at a temperature of about 20, 7 10 days can germinate, open the glass after the seedlings emerge, when the seedlings grow true leaves, remove the glass to move the seedlings, move to a large shallow pot, and the plant spacing is 2 3 cm.

When 2 3 true leaves grow, transplant them in a small tile pot with a diameter of 6 8 cm, and apply thin liquid fertilizer once every 5 7 days; 4 5 true leaves when moving to a 10 cm pot, each time the pot is changed with a mound of soil, placed in a cool place after planting, and given sufficient light after the seedlings are slowed. When the plant grows to 5 6 leaves, the apical buds are removed, leaving 3 4 side buds, and the last 7 8 leaves are planted in pots with a diameter of 20 cm. The potting soil of potted melon leaf chrysanthemum is prepared with humus soil, peat soil plus about 1 4 river sand and a small amount of organic fertilizer, and also half of humus and garden soil plus a small amount of sandy soil.

In order to make the melon leaf chrysanthemum grow vigorously and bloom luxuriantly, it is necessary to pay attention to the following aspects: 1. Preparation before sowing: first of all, the sowing soil should be deeply cultivated, exposed to the sun for about 20 days, and the proportion of sowing soil is 3 parts of humus soil, 2 parts of sandy soil, and a small amount of cake fertilizer is mixed.

The day before sowing, the soil should be disinfected, carbendazim can be sprayed evenly, and then the soil is leveled, and the bottom water is watered so that the soil moisture content is not less than 70. 2. Sowing seedlings: The seedbed should first be shaded, rainproof, and cooled.

Each gram of seeds is sown on the surface of the soil, and after sowing, it is shallowly covered with a thin layer of soil of about 0 5 cm. The soil surface should be kept moist before and after emergence, and the temperature should be controlled at about 25 and the humidity should be controlled at about 60. About 40 days after the emergence of seedlings, seedlings need to be divided, the planting density is 12 12 cm between the rows of plants, and the seedlings need to be shaded for about 10 days during the seedling period, and watered enough at one time.

3. Potting: One month after the seedlings are divided, the pots are made of plastic pots or mud pots with a pot diameter of 18 cm. The ratio of nutrient soil is 6 parts of sandy loam soil, 3 parts of sawdust or rice husk ash, and 1 part of cake fertilizer, which needs to be prepared for backup one month before potting.

During the growth period, apply about 2 light cake fertilizer or 1 nitrogen, phosphorus, potassium compound fertilizer every 7 to 10 days, alternate use effect is better, the growth period may appear pests and diseases powdery mildew, verticillium wilt, etc., pay attention to the humidity in the shed can not be too large, so that the shed maintains good ventilation. Once found, powdery rust and carbendazim can be applied for prevention and control, and the time is once every 10 days, and the spraying is used alternately. After the frost falls, it is necessary to pay attention to frost prevention measures, and keep the temperature in the shed between 4 and 16 to ensure the growth of melon leaf chrysanthemum.

The leaves are soft, spray some water on the leaves to see, in the past, when the leaves of my melon leaf chrysanthemum were soft, it was good to spray on the leaves, and the melon leaf chrysanthemum liked moisture very much.

Melon leaf chrysanthemum is a perennial herbaceous plant that likes abundant sunlight and well-drained fertile soil, so it should be fertilized frequently in order for it to grow lush and bloom frequently. Special attention should be paid to the rapid growth of the pot, to constantly adjust the direction of the pot, so that it can grow upright, not biased to one side. And the light reception of the leaves is also good.
