Water-saving irrigation technology that should be used at present in landscape development

Modern landscape engineering construction irrigation should apply the new technology of landscape irrigation, take reasonable and effective measures to maximize the application value of the new technology of modern landscape engineering construction irrigation, save water resources more effectively, and promote the implementation of the construction of a conservation-oriented society in China. This paper expounds the irrigation technology suitable for the current development of gardens.

1. Micro-irrigation irrigation technology in modern urban gardens

Landscape micro-irrigation irrigation is conducted by using micro-irrigation irrigation system assembled by micro-irrigation equipment, including drip irrigation and micro-spray. As a local irrigation technology, it has certain advantages. Among them, the effective saving and utilization rate of drip irrigation fertilizer is about 70%, the flow rate is relatively small, and it is suitable for irrigation and fertilization of flowers, trees and hedges in a small amount, many times, and the effective saving and utilization rate of water resources is more than 90%, which can further promote the growth of plants, better meet the fertilizer and water requirements of flowers, trees and hedges, and can better save the related costs of garden irrigation management, It is conducive to the effective implementation of garden irrigation automation technology and reduces the labor force of garden irrigation construction. However, micro-irrigation technology also has shortcomings, such as high requirements for irrigation water quality, relatively high cost of garden irrigation construction, and relatively difficult management and maintenance.

2. Micro spray technology in modern urban landscape

The flow of micro-spray is larger than that of drip irrigation, but smaller than that of large sprinkler. Therefore, its atomization effect is relatively ideal, so the damage to flowers in the garden and seedlings in the nursery is relatively small. It is suitable for the irrigation of seedlings, trees and flowers in the nursery, and can effectively form a local humid microclimate in the field.

3. Sprinkler irrigation technology for lawn

Pipeline water delivery conforms to the natural growth and distribution characteristics of lawn roots. It can extensively wet the lawn. The effective rate of water application can reach more than 90%. It is relatively easy to meet the actual water demand of the lawn. It can effectively save about 50% of water resources and can be well applied in lawn irrigation. However, it also has shortcomings, such as the deep leakage loss of water resources and the drift loss of water resources.
