Effects of Soil Amelioration on Photosynthetic Physiology and Soil Respiration of Blueberry

摘要

The best soil for blueberries is a sandy loam that is well drained and contains lots of organic matter. And soil for blueberries should also be acidic. In order to modify the crop land to be fit for blueberry growth, we added several soil conditioners, peat, manure, commercial fertilizer slag, sawdust, pine needle and fungus, to test the abilities to provide nutrition for blueberry. Results showed that all experimental treatments have a role in promoting the growth of blueberry. Peat adding was proved the best soil conditioner here, that it improved soil organic matter content of 94.86%, raised photosynthetic rate of 96.5%, and enhanced soil respiration rate of 4.8%.
