Key points of technical management of ground cover plant maintenance

At present, ground cover plants are an important part of urban green space, and their application has changed from evergreen type to diversified type, from pure lawn to flower type. Because the ground cover plants are characterized by large-area cultivation, under normal circumstances, fine management and conservation are generally not allowed and impossible, and extensive management can only be used as the principle. The management and conservation of ground cover plants mainly focus on the following points:

1. Prevention of soil erosion

The soil must be kept loose, fertile and well drained. Under normal circumstances, it should be inspected 1-2 times a year, especially after heavy rain or typhoon. For places with serious soil erosion, measures should be taken immediately to plug loopholes and cover soil in time, and replant and restore landscape. Otherwise, the losses will continue to expand, resulting in a difficult situation to clean up.

2. Actively cultivate fertility

During the growth period of ground cover plants, fertility should be supplemented in time according to the needs of various plants, especially for some flowering ground cover plants. Fertilization is mainly based on adding thin inorganic fertilizers such as ammonium sulfate, urea, calcium superphosphate and potassium chloride. Sometimes in early spring and late autumn or before and after the dormancy period of plants, the method of sowing and applying is combined with covering soil, which is beneficial to the overwintering of plants, and can be adapted to local conditions, making full use of compost, cake fertilizer, river mud and other organic fertilizer sources.

3. Timely drought resistance watering

Under normal circumstances, the ground cover plants are selected drought-resistant varieties with strong adaptability, which may not be watered, but when there is continuous drought and no rain, watering should be carried out to prevent the ground cover plants from being seriously affected by drought.

4. Pest control

Most ground cover plant varieties have strong resistance to pests and diseases, but sometimes due to poor drainage or improper fertilization and other reasons, pests and diseases can also occur. When planting large area of ground cover plants, the diseases most likely to occur are blight, gray mold, white silk disease, etc., which can cause pieces of ground cover to wither, so spraying measures should be adopted to prevent them from spreading and expanding. The pests most likely to occur are Spodoptera litura, white grubs, aphids, bridge-making insects, etc., after the occurrence of insects should be actively sprayed control.

5. Trim and level in time

Generally, low type varieties do not need to be pruned frequently, and extensive management is the main one. However, due to the introduction of a large number of flowering ground cover plants in recent years, a few with residual flowers or high flower stems must be properly depressed after flowering, or combined with seed harvesting, properly pruned.

6. Update recovery

In the process of ground cover plant management and conservation, the premature senescence of ground cover often occurs due to various unfavorable factors. According to different conditions, the topsoil should be punctured to make the root soil loose and breathable, and at the same time, fertilization and watering should be strengthened, which is conducive to regeneration and recovery. For some perennial ground covers of flowering species, it is necessary to carry out root turning every five or six years, otherwise, it will also cause natural decline. When replanting ramets, senescent plants and diseased plants should be removed, and healthy ones should be selected for replanting.

7. Adjust the ground cover community

The ground cover lasts longer than other plants, but it is not fixed after one planting. Except some varieties have the ability of self-renewal, they generally need to be adjusted properly from the aspects of viewing effect and covering effect. When adjusting, pay attention to color coordination, should be eye-catching, avoid weeds. Such as planting some flowers on the green grass, the color is easy to coordinate, such as low violet, white clover, yellow dandelion. Also like in the road or lawn edge on the snow-white incense snowball, sunflower, it is more elegant, eye-catching and luxurious.

Key points of ground cover plant conservation and management

Key points of ground cover plant conservation and management technology--At present, ground cover plant is an important part of urban green space, and its application has changed from evergreen type to diversified type, from pure lawn to flower type. Because the ground cover plants are characterized by large-area cultivation, under normal circumstances, fine management and conservation are generally not allowed and impossible, and extensive management can only be used as the principle. The management and conservation of ground cover plants mainly focus on the following points:

1, to prevent soil erosion planting soil must be kept loose, fertile, drainage is good. Under normal circumstances, it should be inspected 1-2 times a year, especially after heavy rain or typhoon. For places with serious soil erosion, measures should be taken immediately to plug loopholes and cover soil in time, and replant and restore landscape. Otherwise, the losses will continue to expand, resulting in a difficult situation to clean up.

3, timely drought-resistant watering Under normal circumstances, the ground cover plants are selected drought-resistant varieties with strong adaptability, can not be watered, but when there is continuous drought without rain, in order to prevent the ground cover plants from suffering from serious drought, watering should be carried out.

Most ground cover plant varieties have strong resistance to pests and diseases, but sometimes due to poor drainage or improper fertilization and other reasons, pests and diseases can also occur. When planting large area of ground cover plants, the diseases most likely to occur are blight, gray mold, white silk disease, etc., which can cause pieces of ground cover to wither, so spraying measures should be adopted to prevent them from spreading and expanding. The pests most likely to occur are Spodoptera litura, white grubs, aphids, bridge-making insects, etc., after the occurrence of insects should be actively sprayed control.

5, timely pruning flat general low type varieties do not need to be regularly pruned, mainly extensive management. However, due to the introduction of a large number of flowering ground cover plants in recent years, a few with residual flowers or high flower stems must be properly depressed after flowering, or combined with seed harvesting, properly pruned.

6. Renewal and recovery In the management and conservation of ground cover plants, premature senescence of patches of ground cover is often caused by various adverse factors. According to different conditions, the topsoil is punctured to make the root soil loose and breathable, and at the same time, fertilization and watering are strengthened, which is beneficial to regeneration and recovery. For some perennial ground covers of flowering species, it is necessary to carry out root turning every five or six years, otherwise, it will also cause natural decline. When replanting ramets, senescent plants and diseased plants should be removed, and healthy ones should be selected for replanting.

7. Adjust the ground cover community. The ground cover lasts longer than other plants, but it is not fixed after one planting. Except some varieties have the ability of self-renewal, they generally need to be adjusted properly from the aspects of viewing effect and covering effect. When adjusting, pay attention to color coordination, should be eye-catching, avoid weeds. Such as planting some flowers on the green grass, the color is easy to coordinate, such as low violet, white clover, yellow dandelion. Also like in the road or lawn edge on the snow-white incense snowball, sunflower, it is more elegant, eye-catching and luxurious. Ground cover plants are an important part of urban green space. They have changed from evergreen type to diversified type in application, from pure lawn to flower type. Because the ground cover plants are characterized by large-area cultivation, under normal circumstances, fine conservation is generally not allowed and impossible, and extensive management can only be used as the principle. According to the actual situation of our country and the experience of some cities, the key points of ground cover conservation and management are introduced as follows:

I. Prevention of soil erosion

The soil must be kept loose and fertile, and the drainage must be good. In general, it should be checked once or twice a year. Check carefully for scour damage after a rainstorm. In areas where soil erosion is serious, immediate measures should be taken to plug the loopholes, otherwise the erosion will continue to expand, resulting in a situation that is difficult to clean up.

II. Increase soil fertility

During the growth period of ground cover plants, fertility should be supplemented in time according to the needs of various plants, especially for some flowering ground cover plants. Commonly used fertilization methods are spraying method, the method is simple, suitable for large-area use, can be carried out in the plant growth period, mainly to increase the application of thin ammonium sulfate, urea, calcium superphosphate, potassium chloride and other inorganic fertilizers. Sometimes in early spring and late autumn or before and after the plant dormancy period, the method of sowing and applying, combined with covering soil, is beneficial to the winter of the plant, and can be adapted to local conditions, making full use of compost, cake fertilizer, river mud and other organic fertilizer sources.

III. Drought resistance watering

Under normal circumstances, ground cover plants are selected drought-resistant varieties with strong adaptability, which may not be watered, but when there is continuous drought and no rain, watering should be carried out to prevent ground cover plants from being seriously affected by drought.

Most ground cover plant varieties have strong resistance to pests and diseases, but sometimes due to poor drainage or improper fertilization and other reasons, pests and diseases can also occur. When planting large area of ground cover plants, the disease most likely to occur is blight, which can make pieces of ground cover wither, so spraying measures should be adopted to prevent it from spreading and expanding. Grey mold and coal pollution disease are the second, and attention should be paid to prevention and control.

Insect pests are most likely to occur aphids, bridge-building insects, etc., insects should be sprayed after the occurrence. Because of the large planting area of ground cover plants, prevention should be the main control method.

V. Prevention and control of bald spots

In the large-scale cultivation of ground cover plants, the most afraid of empty bald, especially after the occurrence of empty bald, very unsightly. Therefore. Once it appears, check the cause immediately and turn over the loose soil layer. If the soil quality is poor, it should be replaced and replanted to restore the landscape.

VI. Trimming and leveling

Generally, low type varieties do not need to be pruned frequently, and extensive management is the main one. However, due to the introduction of a large number of flowering ground cover plants in recent years, a few with residual flowers or high flower stems must be properly depressed after flowering, or combined with seed harvesting, properly pruned.

VII. Renewal and recovery

In the process of ground cover plant conservation and management, the premature senescence of ground cover often occurs due to various adverse factors. According to different conditions, the topsoil should be punctured to make the root soil loose and breathable, and at the same time, fertilization and watering should be strengthened to facilitate regeneration and recovery. For some perennial ground covers of flowering species, it is necessary to carry out root replanting every five or six years or so, otherwise, it will also cause natural decline. When replanting ramets, senescent plants and diseased plants should be removed, and healthy ones should be selected for replanting.

VIII. Adjustment of ground cover communities

The ground cover lasts longer than other plants, but it is not fixed after one planting. Except for some varieties with self-renewal ability, it is generally necessary to consider from the viewing effect, covering effect and other aspects, and make appropriate adjustments when necessary.

Pay attention to color coordination, should be eye-catching. Avoid weeds. Such as planting some flowers on the green grass, the color is easy to coordinate, such as low violet, white clover, yellow dandelion. Also like in the road or lawn edge on the snow-white incense snowball, sunflower, it is more elegant, eye-catching and luxurious.
