How to maintain potted chrysanthemums?

Abstract: Chrysanthemum has always been regarded as a symbol of elegance and nobility in Ao Shuang, representing the gentleness and friendship of celebrities. Chrysanthemum, a traditional flower in China, has a long cultivation history. Because it is not afraid of opening in late autumn, it is deeply loved by ancient China literati. So, do you know what is the breeding method of chrysanthemum? How to maintain potted chrysanthemums? Next, let's look at Bian Xiao. What is the breeding method of chrysanthemum?

1, flowerpot selection

Choose a flowerpot with a diameter of about 20 cm and a depth of about 20 cm.

2. Land

The soil can be half garden soil and half orange leaf soil, or half garden soil and half sugar ash mixed evenly.

3. Select a branch

From April to May, young shoots about 5 cm long and vigorous growth are cut from the new branches sprouting from the old roots, which can generally be bought in the flower and bird market.

Step 4 cut

(1) First of all, the prize basin should be padded with 2 ~ 3cm thick broken tiles to facilitate drainage.

(2) Put the prepared pot soil into the pot, and poke a small hole in the soil with a thin bamboo stick with a depth of about 1cm.

(3) After inserting the cuttings into the small holes in the pot soil, gently compact the surrounding pot soil with your fingers.

(4) Each pot can cut about 10 plants, and the interval between each plant is about 3 cm. After cutting, water with a watering can until a small amount of water flows out of the drainage hole at the bottom of the flowerpot.

(5) Three or three days before initial planting, water once a day at night 18, until water flows from the drainage ditch, and keep the soil moist. After 3 days, water every 2 days, but don't let it through, just wet the soil.

(6) Put the flowerpot in a cool place indoors during the day to prevent sunlight exposure, and put the flowerpot outdoors at night.

Step 5 change the pot

(1) After the chrysanthemum is successfully cut,/kloc-0 will grow roots in 5 to 20 days, and after taking root, it can be planted in pots.

(2) Change the pots on cloudy days, and the soil will remain the same. Choose a small pot with a diameter of 12 cm, with one flower in each pot. When changing pots, carefully dig the seedlings out of the soil, leave a little soil at the roots and put them in the new pot by hand.

(3) When the chrysanthemum begins to sprout, put it into a flowerpot with a diameter of 20 cm.

(4) After changing the pot. Water it thoroughly and put it in a cool place indoors. After a few days, you can see the seedlings grow new leaves and then put them outdoors for maintenance.

How to maintain potted chrysanthemums?

1, water

(1) spring. Chrysanthemum seedlings should be watered less once every two days, and the appropriate watering time is 17 pm, which makes the soil moist and is beneficial to the root system development of chrysanthemum seedlings.

(2) Summer. Chrysanthemum seedlings have grown up. Water should be done to ensure that there is water flowing from the bottom of the basin. Water can be done once at 8: 00 and again at 18: 00 in the evening. Spray water on the branches and leaves of chrysanthemum and the surrounding ground with a watering can and soak it.

(3) Before beginning of autumn, properly control the amount of water and water every two days until the water flows out from the bottom of the basin. The watering time is the same as that in spring. After flowering in early autumn, water should be added until it flows out from the bottom of the basin. Water should be watered twice a day for the same time as in summer.

(4) Flowers basically stop growing from winter solstice, so watering should be strictly controlled. Therefore, it is advisable to water once every four days. The watering time is 17: 00 pm, and the soil is wet.

2. Control fertilization

Organic fertilizer (usually used as base fertilizer) should be fully applied to chrysanthemum growth. In the vegetative growth period, topdressing nitrogen fertilizer is the main fertilizer, and some phosphorus, potassium fertilizer and trace element fertilizer can be applied in combination, which can make chrysanthemum branches stout and straight, and also make leaves thick. In the middle and late stage of chrysanthemum growth, phosphorus and potassium fertilizer should be applied mainly, and special fertilizer for flowers can also be applied. Fertilization methods can be combined with soil topdressing and root topdressing, and watering should be done in time after fertilization. Note that if the chrysanthemum leaves are small, thin and yellow, you can spray 0. 1% urea solution several times.

3. Placement and lighting

The daily management of potted chrysanthemum should not only do a good job in soil, fertilizer and water management, but also take timely management measures such as rotating pots and pulling pots according to the growth and environmental conditions of potted chrysanthemum to avoid the influence of light and other reasons on the growth and development of potted chrysanthemum. It should be noted that chrysanthemum is a short-day plant. The experiment shows that chrysanthemum grows nutritionally under the long sunshine of 14.5 hours per day, and the darkness of 12 hours per day and the night temperature of 10℃ are suitable for flower bud development.

4, plastic pruning

The spatial distribution and crown shape of potted chrysanthemum directly affect the ornamental value of chrysanthemum. It is very important to shape and prune chrysanthemum during its growing period. Potted chrysanthemums can be made into fan-shaped crowns, umbrella-shaped crowns, semi-circular crowns and triangular crowns as required. Generally, in the early growth stage of potted chrysanthemums, according to the growth of branches, seeds should be picked and buds should be smeared irregularly to promote branches and shape the ideal crown shape of plants.

Step 5: Wipe buds and sparse buds

Many axillary buds will germinate in the strong seedling stage of chrysanthemum, so it must be pinched off in time, otherwise it will consume a lot of nutrition. During bud pregnancy, lateral buds sometimes appear on the branchlets under the terminal buds. Except what needs to be preserved, the lateral buds should be removed as soon as possible to promote the hypertrophy of the buds. It should also be noted that in the late growth period and flowering period, branches that affect flowering and flower quality can be removed as needed, and residual flowers can be cut off in time to save nutrients and meet the nutrient requirements of flowering flowers in the later period.

6, pest control

The main pests and diseases of potted chrysanthemum are powdery mildew, brown spot, aphid and mite. Many diseases mostly occur in the environment with high air humidity, insufficient light, poor ventilation and large temperature difference between day and night. Therefore, reasonable control of air humidity, humidity and temperature is the main means to prevent these diseases. Carbendazim and thiophanate-methyl can be used as the main physical control methods.
