When will Dabin Chrysanthemum sow?

Dabinju is an ornamental flower with delicate colors, suitable for all kinds of environmental beautification, so when is Dabinju sown?

1. Sowing time of big chrysanthemum

The sowing time of Dabinju is divided into spring sowing and autumn sowing: spring sowing time is February to May; autumn sowing time is August to October.

The large littoralis is compositae, littoralis perennial or biennial herbs, native to Europe. China introduced cultivation. Sunny nature, do not choose soil, garden soil, sandy loam, slightly alkaline or slightly acidic soil can grow.

Plant height 30-70 cm, the whole plant smooth without hair. Stems erect, unbranched or sparsely branched from base, hairy, leaves alternate, long oblanceolate, basal leaves up to 30 cm, upper leaves attenuate, lanceolate, apex obtuse, base attenuate, margin apiculate serrate.

2. Cultivation techniques of Dahlia

1, propagation: multi-use ramets, seeding and cuttage propagation, mainly ramets and cuttage propagation. It is easy to divide plants and reproduce, and the survival rate is high. In the second year of one year, one pier can be divided into 10-15 plants. The principle of plant division is that it is better to divide plants when the aboveground part stops growing and withers. The ramets were divided according to the principle of one bud and one plant. Healthy and well-developed buds were selected for plant division. The bud is not damaged during plant division, and plant division and planting are carried out simultaneously.

2. Land selection and preparation: select garden soil rich in humus, loose and fertile, good drainage, sandy loam soil, neutral and slightly alkaline soil, and use decomposed sheep dung as base fertilizer. Before planting, the soil is deeply ploughed and exposed to the sun to eliminate spores and remove weeds. Base fertilizer is turned in with ploughing, the soil is kept at a certain humidity, and raked flat.

3. Timely planting: planting when the temperature is high, it is easy to germinate early, affecting flowering and flower quality. Plant in combination with rationing, remove dead branches, rotten leaves, diseased branches and weeds before planting. Planting depth 7-8 cm, planting too deep, affecting the next spring germination, too shallow will cause the fall of the year air-dry. Trenching or digging holes for planting, burying and compacting after planting. The plant spacing is 40×60 cm, and the planting density is generally 42 plants/square meter. After planting, pour water once.

4. Watering: After planting before winter, irrigate enough root water to maintain soil moisture. After germination, the watering amount must be sufficient and balanced. When the plant is budding, the watering amount can be increased appropriately. The watering amount should be controlled at low temperature and more watering at high temperature to ensure the ornamental value of the plant. Watering should be done before 9 a.m. or after 8 p.m.

5. Fertilization: According to the growth habits of Dabinju, apply thin liquid fertilizer with balanced nitrogen, phosphorus and potassium once a month during the growth period, strictly control the amount of nitrogen fertilizer, avoid delaying flowering, and add 0.2% potassium dihydrogen phosphate to the thin cake fertilizer water. For plants with early flowering and small flowers, in order to make them have more branches and flowers, the basal branches can be collected to expand plants and increase tillers.

6. Light: Dabinju likes light. In the planting site, remove obstacles affecting light to ensure that Dabinju receives sufficient light.

In addition, pest control is also needed so that the big chrysanthemum can grow better.
