图4. 甘肃陇东苹果园不同覆膜年限苹果树细根构型性状土层差异(平均值±标准差)。CK, 对照; 2Y, 覆膜2年; 4Y, 覆膜4年; 6Y, 覆膜6年。不同小写字母表示不同处理间各指标存在显著性差异(p < 0.05)。
Fig. 4. Soil layer difference of fine root architecture characters with different years of film mulching apple orchard in Longdong, Gansu (mean ± SD). CK, control treatment; 2Y, mulching for 2 years; 4Y, mulching for 4 years; 6Y, mulching for 6 years. Different lowercase letters indicate that there are significant differences (p < 0.05) in each index among different treatments.
