1, temperature lighting: large (small) smudges like a cool climate, hi sunshine. Dahlia is not tolerant to shade. If it is placed in the shade for a long time, it will grow poorly, the roots will be weak, the leaves will be thin, the flowers will be light, and some will not bloom. It has strong adaptability and can grow well under high temperature conditions in summer. In the late autumn, winter and early spring, because the temperature is not very high, it should be given direct sunlight to facilitate its photosynthesis and flower buds, flowering and fruiting. If you are experiencing high temperatures or in the summer, you need to cover it with about 30% of the sun. After being flowered and placed indoors for conservation, it should be placed near the doors and windows in the southeast direction to extend the flowering period as much as possible and increase the number of flowers.
2, soil: avoid heavy soil, should loose and fertile sandy loam. The cultivated soil is preferably fertile sandy loam, and the drainage and sunshine are all good. The dahlia is suitable for loose, humus-rich and well-drained sandy loam. Potted Dahlia planting soil, generally cultivated soil prepared with vegetable garden soil (50%), humus soil (20%), sand (20%) and large manure (10%), the soil is easy to cause waterlogging ,can not be used. In the daily management, the soil is loosened in time, and the water in the basin is removed, because the succulent roots of the dahlia are rotted when the water content in the soil is excessive and the air is poor.
3, watering: potted plants should avoid water, otherwise the bulbs are perishable, watering and fertilizing should be carried out during the growth period, while giving sufficient light to make it grow robust and flourishing. Watering once a day in summer and watering once every 3-5 days in winter. Dahlia enjoys water but avoids stagnant water. It is afraid of both cockroaches and drought. This is because the large flower is succulent and the roots are too perishable. However, the leaves of Dahlia are luxuriant, and the amount of evaporation is large, and more water is needed. If the water is not hydrated and the water is not replenished in time, and then exposed to the sun, the edges of the leaves are lightly burned, and the leaves at the base of the heavy ones fall off. The principle of “drying and pouring†should be mastered in watering. Generally, the seedling stage in the early growth stage needs limited water. The sunny day can be poured once a day to keep the soil slightly moist. It is too dry and too wet, and the growth stage is late. Lush, consuming more water, sunny or blowing northerly weather. Note that it is easy to lack water at noon or evening, and the amount of water should be increased appropriately.
4, fertilization: Dahlia is a kind of hi-fat flower, from the seedlings usually 10-15 days a day to apply a thin liquid fertilizer. Apply once every 7-10 days after the bud. The water should be stopped when the flower buds pass through. It is also not suitable for fertilization when the temperature is high. The amount of fertilizer applied depends on the growth of the plant. Where the leaves are light and thin, it is a lack of fertilizer; on the contrary, if the fertilizer is excessive, the edge of the leaves will be cokeed or the tip of the leaves will be yellow, and the leaves will be thick and dark and green, which is a suitable performance for fertilization. The concentration of fertilization is required to be increased more than once, which makes the stem thick.
5, planting matters needing attention:
(1) Inserting the plant. The stem of Dahlia is empty and brittle, and it is easy to be blown off by the wind. It should be inserted into the bamboo in time, and the bamboo can be inserted to avoid the growth and bending of the branches and enhance the ornamental value of the pot. When the plant grows to a height of more than 30 cm, a small bamboo should be inserted next to each branch and tied with hemp (or thin rope); as the plant grows taller, it should be replaced with a longer insert. Bamboo, the last inserted bamboo should be placed in the lower part of the flower bud.
(2) Protect plants for safe wintering. Dahlia is not cold-tolerant (mainly roots can not be frozen). In November, when the leaves are withered, the ground part should be cut off, moved into the room, and the original pots are preserved. The roots can also be taken out and aired for 1-2 days and then buried in the sand of the indoor micro-tidal moisture, the temperature is not more than 5 degrees, and the potted plants are planted in the spring of the next year.
6. Pests and diseases: Pests and diseases that are easy to occur during the cultivation process of Dahlia; powdery mildew, flower rot, moth, and red spider.
Preparation of hawthorn flower before sowing 1. Seeding container The seeding container of hawthorn flower has special specifications. The seedling pot with height 5cm, length 50cm and width 20cm is used to strictly clean the seedling pot before planting, then add a small amount. Chlorine-free nitrobenzene is sterilized.
2, the choice of seeding soil, the choice of no stones, no pollution, uniform soil, rich in nutrients. If conditions permit, it is better to choose land that can be well drained. There are two kinds of seeding substrates used, one is grass charcoal and the other is garden soil. Generally speaking, river sand, garden soil and humus are used in a certain proportion and then disinfected.
Hawthorn sowing method 1. Sowing time: The seedling tray after disinfection and water seepage can be planted immediately. The seedbeds are usually planted in the middle and late March, and flowerbed-type hawthorn flowers can be planted in late April.
2. Ventilation: After the seeding is completed, the film can be supported by bamboo rafts, etc., so that the crop can be well ventilated, the temperature of the soil is increased, and the evaporation of less points is reduced. This provides the temperature and humidity required for the crop.
Management of hawthorn flower after sowing 1. Moisturizing: The watering of hawthorn flower should be reduced according to the soil environment, and the soil of hawthorn flower should be kept semi-humid. When the soil surface of the hawthorn flower is dry, it is necessary to select the dipping method in time to keep the soil moist. If it is dry for a long time, it should be saved in time, otherwise it will die.
2. Insulation: The benign germination period of hawthorn flower seeds is in the temperature range of 19-21 °C. It is necessary to remember to change the position to make the production environment of hawthorn flowers more suitable. Always ventilate, which can promote the germination and growth of seeds. In the case of higher temperatures, it is necessary to properly cover the shade at the right time. When the seeds are emerged, the kittens should be moved to a place with plenty of sunshine.
After reading the above three aspects of planting steps, perhaps you already have a general idea in your heart. If you are planting hawthorn flowers in batches, it is necessary to pay attention to the moisturizing and ventilation at the moment. In addition, many people will forget the supply of light during the seedling period, so that the seeds grow very slowly. If planting a single plant as a home ornamental flower, it is recommended to change the position of the hawthorn flower from time to time because it has higher temperature requirements. Generally, the bright colors of the hawthorn flowers are grown at a suitable temperature and humidity.
Hawthorn flower pest control (1) Hawthorn flower powdery mildew. The incidence is serious in September-November, and high temperature and high humidity will contribute to the occurrence of diseases. After the victim, the plants were short, the leaves were uneven or curled, and the young shoots developed malformations. After the flower buds are killed, they cannot bloom or can only produce deformed flowers. When the disease is serious, the leaves can be dried up and even the whole plant can die. Control methods: 1 Strengthen conservation, make plants grow robust and improve disease resistance. Control the watering and increase the application of phosphate fertilizer. 2 When the disease occurs, the diseased leaves are removed in time, and spray control is carried out with a solution of 800% of a 50% solution of dexamethasone or a solution of 70% of thiophanate.
(2) Hawthorn flower rot. It occurs mostly during the period from full bloom to falling flower, the soil moisture is too large, and the ground temperature is high, which is beneficial to the occurrence of diseases. When the petals are damaged, the lesions are initially fading green spots, and then become yellowish brown. The lesions are irregular after expansion, yellow-brown to taupe. Control methods; 1 between the plants to enhance ventilation and light; in the later stage, water and nitrogen fertilizers can not be used too much, to increase the application of phosphorus, potassium fertilizer. 2 After the bud period, it can be sprayed with 0.5% Bordeaux mixture or 70% thiophanate 1500 times solution, once every 7-10 days, which has better control effect.
(3) Hawthorn flower moth. The worm mainly harms dahlias and chrysanthemums, and the larvae are burrowed into the stems. When the damage is serious, the plants cannot flower or even be disabled. Control method: Generally, from June to September, spray 90% of the original trichlorfon 800 times solution every 20 days to kill the newly hatched larvae.
(4) Red spider. Red spider is the cinnabar leafhopper, see the control section of the cinnabar leafhopper in "Jasmine".
