Effects of different soil moisture management measures on Camellia oleifera growth
In order to provide some technical supports for soil moisture management and water saving irrigation of Camellia oleifera forest,effects of different soil moisture management measures on fruits,flower buds and leaf anatomical structure in C.oleifera were researched,and the three treatments included natural condition,drought stress and covering straw,using 6-year-old Changlin No.4 C.oleifera forest as test materials.The results showed that,increments of fruit height,fruit diameter,flower diameter,flower height had very significant differences among the three treatments of natural conditions,drought stress and covering straw.Under natural condition and covering straw condition,the leaf anatomical structure was weakly correlated with soil moisture content at different depths.Under drought stress condition,lower epidermis and leaf thickness were moderately correlated (0.5 ＜ r ＜ 0.8) with soil moisture content at different depths.Under natural condition,soil moisture content at different depths was weakly correlated with increments of fruit diameter,flower diameter and flower height,but moderate negative correlated (0.5 ＜ r ＜ 0.8) with fruit height increment.Under drought stress and covering straw conditions,flower diameter and flower height were highly negative correlated (0.8 ＜ r ＜ 1.0) with soil moisture content.Under covering straw condition,fruit diameter was moderate negative correlated (0.5 ＜ r ＜ 0.8) with soil moisture content at four depths.Under drought stress condition,fruit height was moderate positive correlated (0.5 ＜ r ＜ 0.8) with soil moisture content at four depths.
