Statistical characteristics of soil moisture content in different layers in June.

Soil depth (cm)	Min	Max	Mean	STDE	CV (%)	Skewness	Kurtosis	K-S test
0~10	0.32	1.88	0.93d	0.51	0.55	0.40	-1.25	0.42
10~20	2.09	4.22	2.90c	0.70	0.24	0.50	-1.08	0.38
20~30	6.52	10.02	7.90a	1.05	0.13	0.47	-0.88	0.63
30~40	2.43	5.31	3.69b	1.03	0.28	0.28	-1.56	0.37
40~50	2.02	3.65	2.62c	0.58	0.22	0.40	-1.68	0.03

Note: test of K-S representing normal distribution. Different lowercase letters showed that the soil moisture content had significant differences in different layers (), .
