Planting method of Chrysanthemum morifolium

The trees on both sides of the road are covered with Compositae flowers, and the brain automatically pops up: wild hair and delicate fragrance (I can still remember, it seems that I didn't listen to O (∩ _ ∩) O in high school Chinese class). Today's protagonist is Dabin Chrysanthemum. Dabin chrysanthemum has a long flowering period, probably from April to June, so the little friends in Hangzhou can go for a walk in Jiangyangchuan, where a large area has been planted along the path, and it is now in full bloom, which is very beautiful.

Dabin Chrysanthemum is a perennial herbaceous flower, introduced in Europe, so it is also called the western waterfront chrysanthemum. Like most flowers of the family Compositae, the flower head consists of ligulate flowers and tubular flowers. We can see that such a "big waterfront chrysanthemum" is not actually a flower, but an inflorescence made up of many white ligulate flowers and yellow tubular flowers.

Dabin Chrysanthemum not only has high appearance and long flowering period, but also is easy to manage like most Compositae flowers, and belongs to the kind that can grow well by taking care of it casually, so it is used more in the garden flower border. Early summer evening, walking on both sides of the quiet path full of flowers, getting along with flowers, getting along with themselves, temporarily throwing away troubles, stealing half a day's leisure from floating life. Next, I would like to introduce the planting method of Dabin Chrysanthemum.

Propagation: Dabin Chrysanthemum is mainly used for ramet, sowing and cutting propagation, mainly ramet and cutting propagation. The seedlings were sown in autumn or early spring and germinated in about 7 days under the condition of 15-18 ℃.

Soil: Dabin Chrysanthemum has strong adaptability, regardless of soil, garden soil, sandy loam, slightly alkaline or slightly acidic soil can grow. Loose and fertile sandy loam with good drainage should be used for cultivation, and the pH value can be adjusted between 6.5 and 7.0.

Lighting: Dabin chrysanthemum likes sunshine and is suitable to be placed in a sunny environment with strong cold resistance. the basic leaves are still evergreen and semi-overcast in winter in the Yangtze River Basin of China.

Temperature: the suitable temperature of Dabin Chrysanthemum is 15 to 30 ℃. The temperature in seedling stage should not be too high, otherwise it is easy to grow too long.

Fertilizer and water: when cultivated in open field, you should choose a place with good drainage. Dig the soil deeply and apply rotten barnyard manure and sufficient potash fertilizer before planting. Especially after ramet and newly planted seedlings, the management of water and fertilizer should be strengthened to enlarge the plant type as much as possible. During the growing period, the rarefied liquid fertilizer with balanced nitrogen, phosphorus and potassium is applied once a month, and the amount of nitrogen water is strictly controlled, otherwise the florescence will be postponed, and 0.2% potassium dihydrogen phosphate can be added to the thin cake fertilizer water. Control the dosage, excessive will delay the florescence.

Pruning: for the plants with earlier flowering and smaller flowering, in order to make them have multiple branches, multiple flowering can be carried out at the base to achieve the purpose of expanding plants and increasing tillers. The old plants should be planted separately every other year in autumn, and the residual flowers should be cut off in time after flowering.

Diseases and insect pests: there are often leaf spot disease and stem rot, which can be sprayed with 65% zinc wettable powder 600 times. Insect pests are harmful to blind bugs and leaf miners, which are sprayed with 500 times of 25% carbaryl wettable powder.

The reasons for not blooming may be as follows:

First, the sowing time is not ideal.

Second, the temperature in the seedling stage is on the high side and has not gone through the low temperature stage.

The third is the failure to control the amount of nitrogen fertilizer.
