- Abstract:
-
In order to irrigate urban green space of lawn grass more reasonable, the water requirement regulation for Agrostis stolonifera, Dichondra repens, Poa pratensis and Trifolium repens was studied by the micro irrigation experiment in the plots. The results show that: (1) the pattern of root system distribution in the soil is similar to the shape of umbrella, and 83%~94.4% of root system distribut in 0—10 cm depth of soil. Therefore, they need supplementary irrigation timely to maintain their normal growth; (2) the annual total water requirement is about 1000 mm, and 66% of which is concentrated in June, July, August and September. Thus, the turfgrass can not be cultivated in large scale for the construction of urban green land in northern China; (3) the irrigation period is 5 days for turgrass, and it is better to irrigate about 33 mm for the second irrigation.
