How to grow Dutch tulips

Tulip flowers beautiful, floral charming, is the national flower of the Netherlands, a symbol of dignity, beauty, luxury and success. Currently widely distributed in the world, is a common family potted flowers. So, how do Dutch tulips grow?

1. Soil and Fertilization

First of all, choose a flowerpot with a diameter of about 20cm, with sandy loam as good, soil pH as good as neutral alkali. Tulips are more fertile and should be fully applied before planting. Generally, dry chicken manure or decomposed compost is used as base fertilizer and fully irrigated. 2-3 days before planting, careful ploughing and harrowing ensure loose soil. After two leaves are produced, liquid fertilizer can be applied for 1-2 times, compound fertilizer with balanced nitrogen, phosphorus and potassium can be applied for 3-4 times per month in peak season, fertilizer application should be stopped at flowering stage, and liquid fertilizer of potassium dihydrogen phosphate or compound fertilizer can be applied for 1-2 times after flowering.

2. Regulate temperature

The suitable temperature for tulip growth period is 5-20℃, the optimum temperature is 15-18℃, and the growth temperature of plants should be maintained at 0-25℃. The root growth temperature of tulip should be above 5℃, below 14℃, especially about 10℃. The optimum temperature for flower bud differentiation is 17-23℃, and flower bud differentiation will be inhibited when the temperature exceeds 35℃. In addition, tulips have strong cold resistance, winter can withstand low temperatures of-35℃, when the temperature is maintained above 8℃ began to grow.

3. Water management

Excessive irrigation should not be allowed in the cultivation process, but more water should be required within one week after planting, and the water requirement should be reduced after germination, especially when flowering, water should not be too much. If it is too dry, the growth will be significantly delayed. During the growth period of tulips, the air humidity should be maintained at about 80%.

4. Lighting conditions

When the bulbs germinate, the flower bud elongation is inhibited by sunlight. Therefore, deep planting and moderate shading must be carried out to prevent direct sunlight from adversely affecting the growth of seed balls.

5. Seed ball storage

The storage conditions of seed bulbs directly affect flower bud differentiation and flowering time of plants in seed bulbs. After harvest, seed bulbs should be placed in ventilated, dry and cool places as much as possible. If conditions permit, the bulbs can be placed in cold storage at 15-17℃ in the high temperature season from July to August, and the bulbs will develop smoothly and promote flower bud differentiation and development. If the bulb is placed at a high temperature above 35℃, flower bud abortion and abnormal development will occur.

Although tulips have high environmental requirements, it is not difficult to understand their growth habits and use scientific and reasonable breeding methods.
