摘要:
以海南长期深沟盖草培肥后的橡胶园土壤为对象,分析土壤物理性质的空间分异特征。结果表明:施肥沟沟壁容重最低,平均为1.29 g/cm3,比施肥沟沟底低0.11 g/cm3,比萌生带低0.20 g/cm3;施肥沟沟壁毛管持水量最高,平均为51.43%;施肥沟沟壁渗透性系数最高,10℃时渗透系数K10平均为1.51;施肥沟沟壁大团聚体(>250μm)平均含量最高。深沟盖草培肥能够改善土壤团粒结构,增加土壤结构稳定性,使施肥沟沟壁土壤物理性状最好。
Abstract:
This paper studied spatial heterogeneity of soil physical properties under Hainan rubber plantation after Deep groove Mulching Fertilizer. The results showed that: the lowest soil bulk density is fertilization groove wall, an average of 129 g/cm3, lower than the end of fertilization groove 011 g/cm3, lower than the Initiation belt 020 g/cm3;fertilization groove wall capillary moisture capacity is the highest of average 5143%; when 10 ℃ permeability coefficient K10 is the highest 151. Large aggregates (> 250 μm) the average was the highest. Deep groove Mulching Fertilizer can improve soil aggregate structure, increase soil structural stability, the physical properties of soil fertilization Gully wall best.
