Abstract
According to high importance of sodding for fast creating green beds in all seasons, this experiment carried out with aimidentifying suitable substrate and covering plant including two lawn genus and Dichondra with blend seed. The trial carried out as factorial experiment with three factors based on complete block design in three replications. Experimental factors consisted of planting networks (a1: plastic mesh, a2: plastic sack) and planting substrates (b1 :garden soil, b2 :garden soil + carbonized rice husk, b3: garden soil + perlite, b4: garden soil + sand (v/v)) and types of covering plant (c1:Dichondra repens, c2 :Lolium perenne, c3:Poa pratensis, c4: blend seed including Lolium perenne Numan, Lolium perenne common type, Poa pratnesis Cronino, Poa pratensis Commonand Festuca rubra). The results showed the effect of experimental factors was significant on traits such as germination rate, the appearance quality of the lawn, height of the lawn, rooting depth, content of chlorophyll a, b and total, fresh and dry weight of shoots and total plant dry matter (P< 0.01 or 0.05). Based on the results the most chlorophyll content was observed in garden soil and the highest dry matter and plant growth belonged to garden soil + perlite bed. Lolium was the best in the most of traits such as germination rate and plant growth. Chlorophyll content of plants on sack plastic was better than plastic network, but the plastic network was better one in other traits such as dry matter.
