- Abstract:
-
The seedling emergency rate and average plant height of Leymus chinensis which is the common plant in cold regions were observed by using a pot experiment in greenhouse. The seeds of L. chinensis were sowed in different mixed media from a thick-layer matrix used in a demonstration project of highway from Arong Qi to Bork Chart in Inner Mongolia, and cultured at 15℃, 20℃, 25℃ and room temperature, respectively. Results are as follows: the seedling emergency rate and average plant height of L.chinensis increase with temperature rise. The order of seedling emergency rate from high to low in different mixed medias is Mixed 2, Control, Mixed 3 and Mixed 1 (P < 0.05), and average plant height is the sequences of Mixed 2 > Mixed 1 > Mixed 3 > Control (P < 0.05). Furthermore, the difference between average plant height of Mixed 2 and others will be more significant when temperature increases, so Mixed 2 or the media of the ratio of foreign-soils and peat soil(4∶6) can significantly increase seedling emergency rate and average plant height, and make plant better adapt to temperature change . In a word, the Mixed 2 is optimal medium for slope protection in cold regions.
