Abstract:
Taking seedlings of C.Reticulata as test materials，with water as the control (CK)，the effect of different concentrations of glycine on C.Reticulata dry weight，rhizosphere and non-rhizosphere soil nutrient content were studied.The results showed that the dry matter weigh contents at 4 mmol/L were observably higher than others，the soil moisture content in 79.80%~83.95% was requirement for the normal growth of C.Reticulata seedling，the rhizosphere soil pH，in addition to the Gly-N 6 mmol/L was higher than that of non rhizosphere soil，the others were lower.The organic matter content of the rhizosphere was lower than that of the non rhizosphere soil，only including the Gly-N 6 mmol/L.The soil total nitrogen content in rhizosphere was as well as in non rhizosphere soil.As for the soil total phosphorus content，the rhizosphere including CK，Gly-N 2 mmol/L were lower，the others were contrary.For total potassium content the Gly-N 4 mmol/L，the Gly-N 6 mmol/L was higher than that of rhizosphere soil，others were contrary.Under the conditions of this experiment，it was suggested that Gly-N 4 mmol/L treatment was better on C.Reticulata seedling.
