How to plant vetch flowers

Soil: the soil with loose drainage should be selected for planting. Timely watering: the soil can not be too dry or too wet, sunny days need to be watered every day, summer water demand is large, can increase the amount of watering, but not stagnant water. Lighting: no less than 6 hours of light per day. Growth temperature: the suitable temperature is about 10-25 ℃, not less than 5 ℃, not higher than 35 ℃. Propagation method: the method of cutting can be used for propagation. Control diseases and insect pests: mainly control Dahlia borer moth and Botrytis cinerea.

I. introduction of vetch flowers

Vetch flower, also known as Dahlia, Compositae, Dahlia plants, the stem is erect, more branches, plant height of about 1.5-2m, sturdy, it is a perennial herb, with large rod-shaped roots.

The vetch flower, which originated in Mexico, is the national flower of the country. People regard the vetch flower as a symbol of richness and generosity. At present, it has been planted in many countries. It is one of the largest varieties of flowers in the world, probably more than 30,000.

2. Culture methods

1. Soil requirements

Vetch should be planted in loose, well-drained soil, if the soil drainage is not good, it is easy to lead to stagnant water, thus affecting the normal growth of plants, and even root decay and death.

2. Timely watering

Planting soil should not be too dry or too wet, just let the soil maintain a certain humidity, generally sunny days should be watered every day, plants in the growing period and summer high temperature water demand is relatively large, so it should be timely increase watering, but should not be excessive, otherwise stagnant water will cause root rot.

3. Lighting

Vetch flowers need sufficient light in the growth process, no less than 6 hours of light time per day, which is conducive to the rapid growth of plants, such as long-term maintenance of plants in dark or no light, will lead to plant dysplasia.

4. Growth temperature

The suitable temperature for vetch flower growth is about 10-25 ℃. Too high or too low temperature will affect plant growth. The lowest temperature should not be lower than 5 ℃ and the highest temperature should not exceed 35 ℃.

III. Methods of reproduction

Cutting propagation: split roots grow out of the bud seedlings, only to retain one, the other buds grow to 3cm or so can be cuttage, unearthed seedlings grow up to 5cm or so, you can choose a robust seedling to grow, the other can be cuttage, the temperature should be maintained at 20 ℃ or so when cutting, so that the soil to maintain a certain humidity, about 15 days will take root.

IV. Prevention and control of diseases and insect pests

1. Dahlia borer moth: the larva mainly harms the leaves, flowers and stems of the plant. If the disease is serious and will lead to plant death, 50% fenitrothion 100 times solution can be selected for control, or it can also be captured manually.

2. Botrytis cinerea: the disease often occurs in rainy seasons and often occurs in leaves and tender shoots. If the disease is found, the disease should be cut off first, and 80-1000 times of 50% zinc should be sprayed for control.
