How to raise Gladiolus Gladiolus breeding methods and precautions

Gladiolus is a kind of plant suitable for illustration and appreciation, its flowers are very rich in color, with globular branches, the appearance is also covered with brown film, the ornamental value is very high. Many people want to keep a pot of this beautiful flower plant at home. It is a bulbous plant. If you want to maintain it well, you must first protect its bulbs. The following editor shares some planting experience with you.

How to raise Gladiolus

1. Soil: the rich and deep sandy soil requires good drainage, and the sandy slope soil with good drainage is the most suitable. The suitable pH is 5.66.5. it is not suitable to plant in the place where heavy clay soil is prone to waterlogging.

2. Watering: gladiolus is a flower that needs more water. Timely watering and keeping the soil moist are important measures to promote its more flowering. In case of hot and high temperature, it should be sprayed in time to humidify, reduce the temperature, and pay attention to drainage after rain.

3. Temperature: the optimum temperature for growth is 20: 25 ℃ during the day, 10: 15 ℃ at night, the temperature is higher than 27 ℃, the growth is blocked, the petals are easy to burn, less than 10 ℃, the growth is slow.

4. Sunshine: Gladiolus is not tolerant to shade and is a long-sunshine plant. 16 hours a day is the most suitable light. The varieties of cut flowers are greatly affected by light. If the sunshine is sufficient, the growth is strong, the resistance is strong, and the flower color is bright and long-lasting, but in hot summer, avoid strong direct sunlight.

5. Fertilization: gladiolus is a shallow root plant, fertilizer should be applied shallowly, fertilization should take into account both nitrogen, phosphorus and potassium, topdressing at two true leaf stage (after flower bud differentiation) and heading stage, apply dilute fecal water plus urea once, re-apply potassium fertilizer in the middle stage, pay attention to nitrogen control in the later stage, so as not to overgrow the plant and cause lodging. The plots dominated by seed bulb production should be mainly increased with potash fertilizer.

Culture methods and matters needing attention of Gladiolus

I. Culture methods

1. Basin soil

The cultivation of gladiolus should choose sandy soil, the soil layer is deep, good drainage, not easy to accumulate water. Flowerpots had better choose plain pottery pots or plastic pots, with holes at the bottom, so it is best to plant in shallow pots with small height and diameter if it is convenient for ventilation.

2. Watering

Gladiolus seedlings should be watered every 10 days to ensure that the basin soil is moist to prevent the leaf tips from yellowing. It is necessary to replenish water in time after flowering. The summer weather is hot, the water evaporates quickly, and the water can be irrigated every 4 days, and the flowering period can be prolonged by proper water control after flowering.

3. Fertilization

Gladiolus is a fertilizer-loving flower, which should be fertilized in time after planting. Generally, the mature liquid fertilizer is applied 3-4 times a month, pay attention to the content of nitrogen fertilizer and increase the phosphorus and potassium fertilizer to increase the differentiation rate of flower buds. After flowering, calcium superphosphate can be selected as topdressing to promote corm growth.

4. Temperature

Gladiolus usually blossoms after three months of planting, but it is greatly affected by temperature in the process of growth. The higher the temperature during the growth period, the faster the growth, of course, it should be controlled within a certain range.

5. Lighting

Gladiolus likes sunshine, and flower buds will differentiate better under light conditions of more than 14 hours a day. After flower bud differentiation, proper reduction of light time can promote flower bud growth and early flowering.

II. Points for attention

1. The most suitable temperature for gladiolus growth should not exceed 27 ℃, especially in summer, when the temperature is too high, it should be ventilated and cooled in time, which inevitably leads to plant growth weakness.

2. Gladiolus is a bulbous plant, so it is necessary to protect the bulb after flower fade without delay. When the leaves begin to turn yellow, dig out the bulbs, dry them and store them.

How to choose the seed ball of Gladiolus

1. Shape and size

The bulb of gladiolus should be flat ball and medium size. The flat corm indicates that it has been degraded or even aging, so it is not suitable for planting; the bulb is too large, although it germinates more, but consumes a lot of nutrients, and flowering is not good.

2. Whether there are diseases and insect pests

Bulbs without brown or black spots, mildew spots and decay, and no insect bites should be selected.

3. Whether there is any damage to the bud eye and the bottom

Because the bud eye is the place where the bulb germinates after planting, and the bottom of the corm is the place where the root germinates, so these two parts can not be damaged, otherwise it will affect the root and germination, and the plant can not grow and develop normally.

4. The variety should be pure

There are many kinds of gladiolus, when selecting, you should choose purebred, try not to choose hybrid, otherwise you won't get the flowers you want. If you want a specific flower color, you can choose according to the ball. Such as yellow or orange flowers, the base of the bulb will appear yellow

How to store the seed balls of Gladiolus

1. Seed ball and leave seed

The seed ball of gladiolus belongs to the letter ball, and many small balls grow around the big ball. When the seed ball is stored in autumn and winter, the ball can be broken off and planted in spring. Because the corms of Gladiolus degenerated quickly, they were rejuvenated mainly by breeding bulbs.

2. Storage method

Keep it at room temperature: wrap the ball directly in a newspaper or net bag and put it in a cool and ventilated corner.

Cryopreservation: store the seed balls in the refrigerator.

3. Points for attention

Try to change to new soil for planting every year. If the open land is maintained, try to change the location. The planting depth should be at least 5-8 cm to ensure the healthy development of the new ball. The small balls harvested in autumn will be sown in spring the following year, and new balls can be harvested in October. However, it is best to choose seeds the size of soybeans or peas.

This is the end of the planting method of Gladiolus. I hope it will be helpful to you. Gladiolus is not difficult to breed, but any plant needs to be cultured according to its own growth habits, such as gladiolus is vulnerable to diseases and insect pests, so we need to take more precautions in the breeding process.
