What are the key points for green space maintenance?

Greening maintenance is particularly important for property areas. First, it can solidify soil and absorb dust to prevent water and soil erosion; second, it can reduce the ambient temperature and regulate the air and climate; third, it can evaporate water and regulate humidity; fourth, it can evaporate water and regulate humidity; The fifth is that it can absorb harmful gases such as carbon dioxide and sulfur dioxide to purify the air; the sixth is that it can absorb strong sunlight, reflect light and ultraviolet rays, and protect people's eyes; the seventh is that it can absorb and muffle sound, reducing urban noise. ; Eighth, it can beautify the environment and enrich people's lives. Therefore, greening maintenance work is very important, and property service companies should carry out maintenance according to categories.

① During the growing season (April to October), the lawn should be weeded three times a month; pruned and trimmed; potholes should be filled in and the grass leveled to keep the grass flat; the grass should be replanted and protected. Ensure rapid growth; water and fertilize the grass in a timely and targeted manner.

② Vegetation: (including: trees, ground cover plants, etc.) Vegetation must be regularly pruned, fertilized, replanted, tied, loosened, organized, watered, etc. During maintenance, The first is to fertilize, and different types of ground vegetation need to be fertilized at different times to ensure their normal growth; the second is to water; the third is to prune; the fourth is to control pests and diseases; and the fifth is to renew.

③ Flower beds: When maintaining flower beds, you must pay attention to watering in time when the soil in the flower bed dries out to replenish the moisture in the soil. The timing of watering depends on the season. Watering in summer should be done in the morning or evening, generally around 8 a.m. and 5 p.m. Avoid watering at high temperatures around noon, otherwise the soil temperature will rise and the water temperature will be low. After watering, the soil temperature will rise. A sudden drop is not conducive to the water absorption and growth of seedlings. Watering in winter should be done at noon, while watering can be done at any time in spring and autumn. The amount of watering should be sufficient, but not too large. The soil should also be topdressed several times regularly to promote the growth of seedlings.

④Weed removal: At various stages of plant growth, mechanical digging or chemical herbicide treatments are used from time to time to remove non-purpose plants.

⑤ Loose soil: Loose soil in tree and shrub plug trays, usually combined with fertilization and weeding, to improve soil permeability and promote the growth of trees and shrubs. For lawns with a growth period of more than three years, they need to be thinned and drilled with a root thinner and a hole puncher respectively every year. The roots are thinned once a year in early summer and mid-autumn. Drilling can be done in spring, once a year.

⑥ Fertilization: During the one-year maintenance period, trees need to be applied with 3kg/plant of compound fertilizer at one time, 2kg/plant of solitary shrubs, 5kg/m2 of densely planted shrubs and patchwork flowers, combined with soil loosening and weeding. The depth of root distribution in the plug tray (about 20-750px). Apply compound fertilizer 8.5kg/100m2 to the lawn in batches in spring, early summer, late summer and mid-autumn.

⑦ Watering: Test the amount of single watering according to the climate of the green area and local conditions (based on the depth of moistened 1250px planting soil). The number of annual waterings in the northern section is about 40 times, and the southern section needs Increase it about 10 times. The overall annual implementation should be determined based on the climate conditions of the year to ensure normal growth of plants.

⑧Pruning: The shaping and pruning of solitary trees and shrubs should be carried out during the dormant period of the trees. Closely planted shrub belts and cut-shaped spherical solitary shrubs and flowers should be planted in accordance with the technical requirements of their pattern points and crown landscape requirements. In summer and autumn, pruning is carried out according to the growth condition of the plants, and diseased dead branches and emerging branches are cut off. Grass lawn pruning should be carried out for the first time when the lawn has re-sprouted and has reached 10-300px. The height of each subsequent pruning should never exceed one-fifth of the plant height. The remaining height should generally be 5-200px. The height of stubble should be increased by 1 to 2m in dry seasons or dry and windy climate areas. Generally, it should be pruned every 7 to 15 days, and the pruning direction should be changed every time. Clover lawns should be mowed once in summer after the blooming period and again in late fall.

⑨ Prevention and control of diseases and insect pests: Greening maintenance should conduct timely investigation and diagnosis of pests and diseases of green space plants in the project area. In case of unknown pest and disease epidemics, timely treatment should be carried out to prevent the occurrence of major pests and diseases. and spread, we must formulate and adopt scientific and effective prevention and control measures to achieve the purpose of prevention and control by the most economical and effective means.

Effectively implement the plant protection work policy of "prevention first, comprehensive prevention and control".

⑩Replanting: For plant defects during greening maintenance, a replanting plan should be formulated based on the biological characteristics of the defective plants, and replanting should be done in appropriate seasons to ensure plant survival. Trees and shrubs can be replanted in early spring or autumn, and lawns are best replanted in May, June, and September. Machinery maintenance: The staff engaged in greening maintenance should be technicians who have received basic skills and knowledge training in the gardening profession, are familiar with the biological characteristics of general garden plants and cultivation and management skills and techniques, and can skillfully carry out maintenance and cultivation management. Able to skillfully operate various required garden machines and tools for various tasks, and be able to perform simple maintenance and repairs. Commonly used garden machinery and tools should include lawn mowers, hedge trimmers, lawn thinners, lawn mowers, sprayers, etc. Facility maintenance: Regular maintenance of pump room facilities and equipment to ensure normal operation of the equipment. Regularly repair or replace the sprinkler irrigation pipe network system, and do a good job of drainage of the pipe network in winter to ensure normal irrigation of the green area.
