| چکیده | ||
| Considering a large number of cities located in arid and semi-arid climatic regions of the world with limited water resources, reducing water consumption and maintenance costs is an important research and implementation priority in urban landscaping. In other words, reducing the high costs of irrigation, increasing water use efficiency and reducing weed competition are important factors in achieving sustainable green spaces in arid and semiarid regions. Application of mulches is one of the suggested strategies for maintaining bed moisture and weed control. In this research, the effects of organic and inorganic mulches on the performance of the flowering plant of Blanket flower (Gaillardia sp.) were investigated in the arid climate city of Mashhad located in the northeast of Iran. The experiment was conducted as a randomized complete block design with three replications. The four mulch treatments included wood chips, scoria, pine leaves, polyethylene as a layer mulch, and no mulch as the control. The polyethylene mulch inhibited the weed growth up to 100%, and other mulch types also significantly reduced the percentage of the weed coverage (p≤0.01). Application of pine leaves delayed the flowering for seven days while polyethylene caused an early flowering to six days compared to the control. Using different mulch types in water shortage conditions of urban landscapes in arid and semi-arid regions is recommended. | ||
