【Abstract】 Growth of Dianthus carryophllus grown in soilless substrate containing two parts of cinder in raw,one part of wood dust and one part of sand over summer was studied in the experiment. The results indicated that soilless cultivation not only improve rhizosphere environment, promote plant growth,but also enhance the capacity of resisting to plant disease and raise rate, which effectively improving the growth\|obstruction caused by high temperature.更多还原
