Straw Mulching Reduces the Harmful Effects of Extreme Hydrological and Temperature Conditions in Citrus Orchards
Figure 4
Seasonal variation in and annual total runoff under control (CK) and straw mulching (SM) treatments during 2010 and 2011.
Error bars are twice the standard error of the mean (n = 3). Statistically significant differences are given after Wilcoxon signed rank test; Notations a and b indicate statistical significance at P<0.05 between CK and SM.
