Dahlia planting Management and Dahlia Cuttage Technology

In our life, plants are a part of our life. With the continuous development of the times, all kinds of flowers appear in our life. Dahlias are native to Mexico and are the national flower of Mexico. Let's take a look at the planting management and cutting techniques of dahlias.

Dahlia planting management 1. Dahlias are generally put on the pot in the middle of October, with 1-2 plants in each pot, and then sprayed with new high-fat film on the plant surface, which is conducive to the rapid growth of the plant. 2. When the seedling grows 10-12 cm in height, two nodes are left to peel off the top, and the number of branches in each pot reaches 6-8. The last pick of the heart is carried out 40-50 days before the Spring Festival, so that it is convenient to control flowering during the Spring Festival. 3. Watering: water dahlias 2-3 times a day so that water can be properly controlled to promote flowers before flowering. 4. Fertilization: nitrogen fertilizer was applied mainly in the early stage and phosphorus and potassium fertilizer in the later stage. Generally, inorganic fertilizer is applied every 10 days, and organic fertilizer is applied once a month. 5. Pest control: regular spraying to protect foot leaves. 6. Binding bamboo: after the last heart is removed and branches are fixed, begin to bind bamboo, one piece of bamboo for each branch, and remove too many side branches at the same time for ventilation. 7. Picking buds: when the buds of Dahlia grow to the size of peanuts, each branch leaves 2 buds, other buds are removed and sprayed with Zhuangtiling, the petals are enlarged, the flowers are colorful, and the flowering period is prolonged. 8. Fixed buds: when the buds are red, only one bud is left for each branch. Dahlia cutting technique for land preparation selects fields with deep tillage layer, loose and fertile land, flat terrain and good drainage. Before deep ploughing, 125 kg of calcium superphosphate per mu is applied as base fertilizer, plus 0.5 kg of 50% sub-farmers, soil disinfection, soil depth of about 15 cm, and then rake, do high or flat bed width of 2 meters, ditch depth of 20 cm, open internal and external "three ditches" to facilitate drainage. The main diseases of Dahlia are powdery mildew and brown spot. From June to October, the leaf tender stem, flower stalk and flower bud of Dahlia will be affected, which will affect the normal growth of Dahlia. Spraying with 50% carbendazim 500 times solution or 50% Dysen zinc 800 times solution can effectively control the occurrence of the disease. The second flowering period of harvested and stored dahlias is from September to October. When the second flowering period is over, the plant stops growing, that is, 10 cm root neck is left before Frosts Descent. Cut off the branches and leaves, dig up the roots and air for 1 to 2 days, so that the surface is dry and stored in 3-5 ℃ cold room for sand storage. The next spring can sprout, branch and blossom. Summary: the above is the planting management of Dahlia and related cutting techniques, friends in need can carry out relevant reference. Different flowers have different ways of reproduction, there are many differences in the specific details, please pay a little attention to the planting process. Dahlia planting Management and Dahlia Cuttage Technology

In our life, plants are a part of our life. With the continuous development of the times, all kinds of flowers appear in our life. Dahlias are native to Mexico and are the national flower of Mexico.

Dahlia cutting technique for land preparation selects fields with deep tillage layer, loose and fertile land, flat terrain and good drainage. Before deep ploughing, 125 kg of calcium superphosphate per mu is applied as base fertilizer, plus 0.5 kg of 50% sub-farmers, soil disinfection, soil depth of about 15 cm, and then rake, do high or flat bed width of 2 meters, ditch depth of 20 cm, open internal and external "three ditches" to facilitate drainage. Cutting method from June to August, lateral buds grow to 15 to 20 cm, combined with lateral buds cut along with sowing. The cuttings need 3 buds, leave the upper 2 buds, cut the third buds to the base of the leaves, insert the second buds into the soil, water them thoroughly, and use 50% shade net for double shade. Water one in the morning and one in the evening on a sunny day, watering continuously for half a month, and the soil moisture is kept at 90% for 3 weeks. The survival rate is very high, and it can blossom in the autumn of that year. After the field management cuttings survived, the saturated leaching solution of compound fertilizer was applied before and after flowering, and 400 ml mother solution was added to each back sprayer (about 12.5 kg). Dahlia should not be ploughed deep after rooting, so as not to damage the root tuber and prevent grass damage. Because the plant is succulent and soft, it is necessary to stand up so as not to break the stems and leaves. When the seedlings of small flowers are 15 cm high, they are topped to make the plants stout and blossom. After the flowers are taken off in time, the flowering period can be prolonged. The main diseases of Dahlia are powdery mildew and brown spot. From June to October, the leaf tender stem, flower stalk and flower bud of Dahlia will be affected, which will affect the normal growth of Dahlia. Spraying with 50% carbendazim 500 times solution or 50% Dysen zinc 800 times solution can effectively control the occurrence of the disease. The second flowering period of harvested and stored dahlias is from September to October. When the second flowering period is over, the plant stops growing, that is, 10 cm root neck is left before Frosts Descent. Cut off the branches and leaves, dig up the roots and air for 1 to 2 days, so that the surface is dry and stored in 3-5 ℃ cold room for sand storage. The next spring can sprout, branch and blossom. Summary: the above is the planting management of Dahlia and related cutting techniques, friends in need can carry out relevant reference. Different flowers have different ways of reproduction, there are many differences in the specific details, please pay a little attention to the planting process.

Cutting technique of Dahlia

Dahlia (Dahlia pinnata Cav.), alias Dahlia, Tianzhu Peony, Oriental Chrysanthemum, Dahlia, Sweet Potato, Compositae, Dahlia, perennial herbs, with huge rod-shaped roots. Stem erect, much branched, 1.5-2 m tall, stout. Native to Mexico, Mexicans regard it as a symbol of generosity and richness, so they respect it as the national flower.

At present, it is planted in most countries in the world, and new varieties are selected from time to time. According to statistics, there are more than 30,000 dahlia varieties, which is one of the species with the largest number of flower varieties in the world. Dahlia flower color flower shape reputation is various, rich and colorful, is one of the world's famous flowers; another can promote blood circulation and dissipate blood stasis, has a certain medicinal value. Dahlias can be sown and cultured, but mainly by root division and cutting. The author now makes a brief introduction to the technology of cutting culture. 1. Land selection and land preparation: select fields with deep tillage layer, loose and fertile land, flat terrain and good drainage. Before deep ploughing, 125 kg calcium superphosphate per mu is applied as base fertilizer, plus 50% of sub-farmers 0.5 kg, soil disinfection, soil deep turning about 15 cm, and then rake flat, do high or flat border width 2 meters, ditch depth 20 cm, open internal and external "three ditches" to facilitate drainage. two。 Cutting method: from June to August, lateral buds grow to 15 to 20 cm, combined with lateral buds cut along with sowing. The cuttings need 3 buds, leave the upper 2 buds, cut the third buds to the base of the leaves, insert the second buds into the soil, water them thoroughly, and use 50% shade net for double shade. Water one in the morning and one in the evening on a sunny day, watering continuously for half a month, and the soil moisture is kept at 90% for 3 weeks. The survival rate is very high, and it can blossom in the autumn of that year. 3. Field management: after the cuttage survived, the saturated leaching solution of compound fertilizer was applied once before and after flowering, and 400 ml mother solution was added to each back sprayer (about 12.5 kg) for extra-root topdressing. Dahlia should not be ploughed deep after rooting, so as not to damage the root tuber and prevent grass damage. Because the plant is succulent and soft, it is necessary to stand up so as not to break the stems and leaves. When the seedlings of small flowers are 15 cm high, they are topped to make the plants stout and blossom. After the flowers are taken off in time, the flowering period can be prolonged. 4. Disease prevention and pest control: Dahlia mainly has powdery mildew and brown spot, which harms the tender stems, flower stalks and flower buds of Dahlia leaves from June to October, affecting the normal growth and prevention as soon as possible. Spraying with 50% carbendazim 500 times solution or 50% Dysen zinc 800 times solution can effectively control the occurrence of the disease. 5. Harvest and storage: the second flowering period of Dahlia is from September to October, when the second flowering period is over, the plant stops growing, that is, leave 10 cm root neck before Frosts Descent, cut off the branches and leaves, dig up the roots and let them dry for 1 to 2 days, so that the surface is dry and stored in 3-5 ℃ cold room for sand storage. The next spring can sprout, branch and blossom. (Shanghai Zhang Weifang)
