Referring to the management standards and related norms of landscaping in Shanghai and other places, combined with the actual situation and the work experience of gardeners, the Management and Maintenance Regulations of Landscaping were formulated and implemented, so that the specific contents and effects of daily maintenance work such as weeding, loosening soil, ridging soil, watering, fertilizing, pruning, shaping, disease prevention, insect prevention, replanting, transplanting, cold prevention, typhoon prevention, sanitation and safety maintenance can be measured as a guiding standard.
Two, maintain and improve the green water supply facilities to ensure the normal operation of the irrigation system.
There are a large number of hedgerows, flowering shrubs and large areas of oil grass in the park, with poor soil quality (easy to harden, sandy, not fertile enough, poor water and fertilizer conservation), large water demand and many times. The existing water supply system has some problems, such as insufficient number of automatic sprinkler irrigation points, uneven distribution, poor nozzle angle, some nozzles and valves damaged and leaking, inconvenient access to open-air parking lot, poor connection of water supply pipe network, etc., which are easy to cause waste of water resources, waste of manpower, low efficiency and difficult to guarantee irrigation quality. The park will intensify inspection, repair and maintenance, and improve relevant irrigation facilities, hoping to eradicate the above problems and provide gardeners with convenient, easy-to-use, reasonable layout and normal operation of green water.
Third, strengthen the pruning of lawns and flowering shrubs, make proper artistic shaping of banyan trees and create a good plant landscape.
Regularly mow the large-leaf oil grass lawn to maintain a high degree of unity (height less than 8CM), neat edges and evergreen all the year round. Hedges are usually newly cut and have a clear outline. Some hedges increase the level and contrast on the facade, requiring high consistency, no fault, uniformity, angular and full growth. Most of the banyan trees in the garden have not been artificially shaped and have not fully reflected the original design ideas. Therefore, it is appropriate to shape banyan trees (cylindrical or cuboid, frustum) around the central platform and bus station respectively to create a better landscape of artistic plant communities.
Four, increase the reasonable guidance and safety warning signs, improve the service facilities.
Making, hanging and placing necessary tree introduction boards and safety warning signs can publicize and popularize botanical knowledge, reduce tourists' trampling on grasslands and flowers and trees, maintain the good appearance of gardens, enhance safety awareness, reduce misunderstandings and disputes, cultivate tourists' good social morality, create excellent social benefits and directly improve the taste and social visibility of parks.
Fifth, strengthen the comprehensive management of lawn weeds and improve the purity of oil grass seeds.
For various reasons, short weeds and oil weeds are mixed together, and some are even more serious. The park will increase the intensity of manual weeding, strive to remove weeds early and small, and apply selective herbicides to kill lawns with serious weeds. The plots with poor growth and serious baldness should be changed, updated or patched to ensure that there is no obvious weed growth, and the oil grass with big leaves grows well, with high purity and high coverage.
Six, timely replant dead, missing hedges, flowers and trees, keep the green space clean and perfect.
Some hedgerows, lawns, flowers and trees in the park died or were lost due to excessive trampling by tourists, or excessive malignant weeds, or poor site conditions (such as red clover, lantana, dragon boat flower, perilla, etc.). ), and some trees, such as Du Ying, with sharp leaves, have been replanted but died after being blown down and righted by the typhoon, or have been destroyed by drought-eating pests, which greatly affects the integrity and aesthetics of the green space. In spring, the park will raise funds through various channels to repair, replant or replant dead or missing lawns, flowers, shrubs and trees with no renewal value, so as to strive for all green spaces to be intact and grow well in the first half of the year.
Seven, strengthen pest control and fertilizer and water management, to ensure that plants thrive, healthy and normal, full of vitality.
A large number of big trees are planted in the garden, and there are many wounds after pruning during transplantation, which causes borers such as longicorn beetles and diamondback moth larvae, such as Huanghuai, Du Ying with sharp leaves and Manmianzai. In addition, termites do great harm to large and old trees such as Ficus tenuifolia, so it is suggested to strengthen comprehensive control by means of artificial control and drug control. Some flowers and trees, such as chlorophytum, agave and other leaf spot diseases, usually pay more attention to prevention, timely drug control. Due to the poor soil quality, sandy soil and poor water and fertilizer conservation in some areas of the park, some flowers and trees are not growing well. When the weather is sunny and dry, irrigation should be increased, quick-acting compound fertilizer or foliar fertilizer should be applied at the top during the growth period, and long-acting farmyard manure should be applied in moderation during the dormancy period to keep flowers and trees evergreen and full of vitality.
Eight, completes the typhoon, cold and other protective measures, timely handling of emergencies.
Before the typhoon comes in summer and autumn, cut off the branches and leaves of some trees with shallow roots, high crowns and unstable centers of gravity, and pay attention to setting wooden stakes to protect the trees. After the typhoon, the trees damaged or broken by the typhoon should be trimmed and straightened in time, and the potential safety hazards such as accumulated water should be removed. Before the arrival of winter, take corresponding heat preservation measures for tropical plants that are not cold-tolerant, such as sisal and perilla. All trees above the ground 1.2- 1.0 meters below the ground should be painted with lime water of about 1: 10, which can play a role in preventing cold and freezing, pests and diseases and beautifying.
Nine, improve the comprehensive quality of gardeners, and build a relatively stable, professional, strong combat effectiveness and quick response maintenance team.
Regularly organize discipline education and technical business study for horticultural workers, visit and study elsewhere when conditions permit, and establish a team that can strictly abide by relevant rules and regulations, be familiar with technical operation and business work, and independently carry out landscaping maintenance management. At the same time, we should pay attention to training technical business backbones and managers, maintain the relative stability of the workforce, and make all work step into a planned, purposeful and step-by-step normal state.
Ten, establish and improve the technical archives of plant conservation management, easy to summarize and establish a complete technical archives of plant conservation, including quantity, source, tree species (including name, alias, scientific name, family, origin, habit, use, etc.). ), specifications, planting year, growth potential, daily maintenance measures, management and protection effects and natural conditions, single technical data, statistical reports and surveys. , timely collection, accumulation, sorting, analysis and summing up experience, sorting, binding, cataloging, classification and filing.
