Culture methods and pruning techniques of asparagus

Although asparagus is not bamboo, its leaves are soft, green all the year round, and its branches look like bamboo, but compared with tall and straight bamboo, it highlights its elegant and unrestrained posture, so it is called asparagus. So, what are the breeding methods and pruning techniques of asparagus?

I. Culture methods of asparagus

1. Temperature

Asparagus prefers a warm environment, and the suitable temperature for growth is 15 ℃-25 ℃. It will stop growing when the temperature is higher than 32 ℃ in summer. It is best to keep the temperature above 10 ℃ in winter, and freezing damage will occur if the temperature is lower than 5 ℃.

two。 Light

Asparagus like semi-overcast environment, it is best to put in the indoor with astigmatism, except in winter, the rest of the season can not be placed in direct sunlight, especially in summer, must not be exposed to the hot sun. Flowering period is not only afraid of wind, but also afraid of rain, but also pay attention to good ventilation, otherwise it will cause falling flowers without seeds.

3. Moisture content

Asparagus likes to be wet, but avoid watering too much. Because too much water will cause the roots to rot. The higher the air humidity, the better. In hot weather, we should often spray water to the ground, branches and leaves around the plant to increase the air humidity. The basin soil should not be too dry. Too dry will make asparagus wither.

Watering method: water once every 3-5 days in spring and autumn and once every 2 days in summer. The temperature is low in winter. It is necessary to reduce the amount of water to avoid freezing the rhizome. At the same time, pay attention to that the water temperature should be as close as possible to the surrounding temperature.

4. Soil

Asparagus likes loose and fertile soil, at the same time, asparagus has high requirements for drainage, it is best to choose humus-rich soil, peat soil and other loose and well-drained soil, a little organic fertilizer can be added to the soil, which will be more conducive to plant growth.

5. Fertilizer

Although asparagus is not a fertilizer-loving plant, there can be no shortage of fertilizer. Fertilization should be thin and diligent, do not apply thick fertilizer, otherwise it is easy to cause branches and leaves to turn yellow. In the spring and summer growing season, nitrogen fertilizer is the main fertilizer, and the mature thin liquid fertilizer can be applied once a month. When the plant is stereotyped, fertilization should be properly controlled to avoid excessive growth and affect the beauty of the plant type.

Second, what is the construction technology of asparagus?

1. Basin control method

The ratio of flowerpot to plant size should be 1:3, which can limit the growth of root system and keep the plant size unchanged.

two。 Remove the growing point

When the new buds grow to 2-3cm, the removal of the growing point can promote the regeneration of branches and leaves on the stem, control its non-growing vines, flatten out the branches and leaves, and make the plant shape plump continuously.

3. Utilization of phototaxis of asparagus

Turning the direction of the flowerpot at the right time can modify the growth shape of branches and leaves and keep the plant type unchanged.

4. Object concealment method

That is, use a piece of hard paper to press the branches and leaves or block the sun, so that when the branches and leaves grow, they will turn or bend when they encounter objects, so as to achieve the purpose of modeling.

Asparagus is a plant with high ornamental value, light posture, chic posture, elegant and quiet, can be placed in the living room, study, add academic flavor.
