What are the key points of green space conservation?

Greening maintenance is particularly important for the property area. First, it can fix soil and dust and prevent soil erosion; Second, it can reduce the ambient temperature and adjust the air and climate; Third, it can evaporate water and adjust humidity; Fourth, it can kill bacteria and insects; Fifth, it can absorb harmful gases such as carbon dioxide and sulfur dioxide and purify the air; Sixth, it can absorb strong sunlight, reflected light and ultraviolet rays to protect people's eyes; Seventh, it can absorb sound, eliminate noise and reduce urban noise; Eighth, it can beautify the environment and enrich people's lives. Therefore, greening and maintenance work is very important, and property service enterprises should be classified for maintenance.

① Growing lawn (4? 10), weeding 3 times a month; Pruning and trimming; Fill the potholes, level the grassland, and keep the grassland flat; Replanting grassland, strengthening protection to ensure the rapid growth of grassland; It is necessary to water and fertilize the grassland in a timely and targeted manner.

② Vegetation: (including: trees, ground cover plants, etc. Vegetation must be trimmed, fertilized, replanted, bundled, loosened, tidied and watered regularly. When maintaining, fertilization should be carried out first, and different types of ground cover plants should be fertilized at different times to ensure their normal growth; The second is to ask for water; The third is pruning; Fourth, pest control; The fifth is to update.

③ Flower beds: When maintaining flower beds, we must pay attention to watering them in time when the soil of the flower beds is dry, so as to make up the moisture in the soil. The watering time depends on the season. Summer watering should be carried out in the morning or evening, usually around 8: 00 am and 5: 00 pm. Avoid high-temperature watering around noon, otherwise the soil temperature will rise and the water temperature will be low, which will make the soil temperature suddenly drop after watering, which is not conducive to the absorption and growth of water by seedlings. It is advisable to water at noon in winter and at any time in spring and autumn. There should be plenty of water, but not too much. It is also necessary to regularly topdress the soil several times to promote the growth of seedlings.

(4) Weeding: at all stages of plant growth, mechanical weeding or chemical herbicide treatment is adopted irregularly to remove non-target plants.

⑤ Loosening: Loosening is generally combined with fertilization and weeding to improve soil permeability and promote the growth of trees and shrubs. For lawns with a growing period of more than three years, it is necessary to use a rooter and a puncher to root respectively, once a year in early summer and Mid-Autumn Festival, and once a year in spring.

⑥ Fertilization: During the one-year maintenance period, 3 kg of compound fertilizer, 2 kg of solitary shrub, 5 kg/m2 of densely planted shrub belt and patch flower were applied to the root distribution depth (about 20? 750 pixels) .8.5 kg/100 m2 compound fertilizer was applied to the lawn by stages in spring, early summer, late summer and Mid-Autumn Festival.

⑦ Watering: According to the climate of green space and local conditions, test the single watering amount (based on the wetting depth of 1250px planting soil). The annual watering frequency in the northern section is about 40 times, and it needs to be increased by about 10 times in the southern section. The overall implementation of the year should be decided according to the climatic conditions of the year to ensure the normal growth of plants.

⑧ Shaping: The shaping and pruning of solitary trees and shrubs should be carried out during the dormant period of trees. Close-planted shrubs and pruned spherical solitary shrubs and flowers should be pruned in summer and autumn according to their technical requirements of type points and crown landscape requirements, and diseased dead branches and budding branches should be pruned according to plant growth. Mowing the lawn should sprout on the lawn 10? Prune 300px for the first time, and the height of each pruning in the future should never exceed 1/5 of the plant height, and the pruning height is generally 5? 200 pixels. The stubble height should be increased by 1? 2 million. Usually every 7? Prune every 15 days, and change the pruning direction every time. Clover lawn should be trimmed once after the full flowering period in summer and once at the end of autumn.

Pet-name ruby pest control: The green space in the project area should be investigated, diagnosed and identified in time for greening maintenance. In case of unknown pests and diseases, it should be handled in time to prevent the occurrence and spread of major pests and diseases. Scientific and effective preventive measures should be formulated and taken to achieve the purpose of prevention and control by the most economical and effective means. Effectively implement the plant protection policy of "prevention first, comprehensive prevention and control".

Attending replanting: For plant defects in the process of greening and maintenance, a replanting plan should be made according to the biological characteristics of the defective plants, and replanting should be carried out in a suitable season to ensure the survival of the plants. Trees and shrubs can be replanted in early spring or autumn, and it is better to replant lawn in May, June and September.

Maintenance of machines and tools: The personnel engaged in greening and conservation should be technicians trained in basic skills and knowledge of landscape architecture, familiar with the biological characteristics and cultivation management skills of general garden plants, skilled in various operations of conservation and cultivation management, skilled in operating various garden machines and tools needed, and able to carry out simple maintenance and repair. Common garden tools should include lawn mower, hedge trimmer, lawn root thinning machine, lawn mower, spray-pull pesticide sprayer, etc.

Facilities maintenance: regularly maintain the facilities and equipment of the pump room to ensure the normal operation of the equipment. Regularly repair or replace the sprinkler irrigation pipe network system, do a good job in winter pipe network drainage, and ensure the normal irrigation of green space.
