The artistic effect of the flower bed depends on the design, the choice of flower varieties and the technical level of construction. However, whether it can ensure robust growth, lush flowers and bright colors depends largely on daily maintenance and management.

First of all, water

After the flower seedlings are planted, they should be watered continuously during the growth process to supplement the lack of water in the soil. The watering time, frequency and irrigation amount should be flexibly mastered according to the climatic conditions and seasonal changes. If you can, you should also spray water, especially for patterned flower beds and three-dimensional flower beds. You should always spray foliar water. Because flower seedlings are generally more delicate. So pay attention to the following aspects when spraying water:

(a) the daily watering time, generally should be arranged before 6 am 438+00 or after 2 ~ 4 pm. If you only water it once a day, it should be arranged around evening; Avoid watering at noon, because the temperature is high and the sun shines directly at noon. Because the soil temperature is high at this time, when cold water is poured, the soil temperature drops sharply, which is unfavorable to the growth of flower seedlings.

(2) The amount of water should be moderate each time, the ground should not be wet, the bottom layer is still wet, and the amount of water should not be too large. The soil is often too wet, which will lead to flower root rot.

(3) The water temperature should be appropriate. Generally, the water temperature in the spring and autumn rainy season should not be lower than10℃; It should not be lower than 15℃ in summer. If the water temperature is too low, it should be dried in advance and watered after the water temperature rises.

(4) When watering, control the flow, not too fast, so as not to scour the soil.

Second, fertilization.

The fertilizer needed by grass flowers mainly depends on the basic fertilizer applied by people during soil preparation. In the growth process of field planting, topdressing can also be carried out many times as needed. When topdressing, be careful not to pollute flowers and leaves. Water it in time after fertilization.

For bulbs, organic fertilizer that is not completely decomposed cannot be used, otherwise the bulbs will rot.

Third, intertillage weeding

Weeds in flower beds compete with flower seedlings for fertilizer and water, which not only hinders the growth of flower seedlings, but also affects the appearance. Therefore, weeds should be removed in time when found. In addition, in order to keep the soil loose, which is conducive to the growth of flower seedlings, it is necessary to cultivate and loosen the soil frequently. However, the depth of intertillage should be appropriate to avoid damaging the flower roots. Weeds, residual flowers and fallen leaves behind the middle roots should be removed in time.

Fourth, pruning

In order to control the plant height of flower seedlings, promote the tillering of stems, ensure the dense and robust flowers and keep the flower beds neat and beautiful, remove residual flowers and broken leaves at any time and prune them frequently.

Generally, the residual flowers are cut off 2 ~ 3 times a week in flowering period.

Pattern flower beds should be trimmed frequently to keep the patterns clear and tidy.

For bulbous flowers in flower beds, if they bloom excessively, pedicels should be cut off in time to eliminate litter and promote bulbous development.

Verb (abbreviation of verb) transplantation

If the flower bed is short of seedlings, replant it in time to keep the flower bed seedlings in good condition. The varieties and specifications of replanted seedlings should be consistent with the flower beds.

Six, column

For tall plants with big flowers, columns are used to prevent lodging and breaking. Tie the stem gently to the post. The material of the column can be thin bamboo poles or some plants with many flowers and big flowers. In addition to erecting columns, lead wires should be woven into flower trays to hold flowers. Don't affect the line of sight of the flower bed, and it's best to paint it green.

Seven, pest control

In the process of flower seedling growth, attention should be paid to timely prevention and control of pests and diseases on the ground and underground. Because grass plants are delicate, the applied pesticides should be controlled at an appropriate concentration to avoid phytotoxicity.

Eight, replace the flower seedlings

Because of the short growth period of grass flowers, in order to maintain the regular ornamental effect of flower beds, it is often necessary to replace flower seedlings.

The bottom plant material should be composed of annual, biennial or perennial herbs, bulbous flowers and light-colored shrubs. The bottom plant material should be a variety with consistent flowering period, exposed flowers, neat plant height, coordinated leaf color and shape, and easy configuration. Flower beds must be selected with biological characteristics in line with local site conditions.

Flower beds pay attention to group effect, meet functional requirements and coordinate with the environment. Patterned flower beds require clear patterns, bright colors and strong contrast; Natural flower beds require bright colors and elegant appearance.

Nine points for attention:

1: According to the weather conditions, ensure water supply, water in the morning, and prevent soil from rushing to the stems and leaves when watering.

2. Do a good job in drainage measures, and strictly accumulate water in rainy season.

3. In the vigorous growth period of flowers, topdressing should be appropriate, and the amount of fertilization depends on the types of flowers. Water should be sprayed immediately after fertilization, and it is forbidden to pollute the surface of stems and leaves with fertilizer.

4. During flower changing, soil improvement and soil disinfection must be carried out more than once in one year.
