栗钙土钙积层扰动对土壤物理性质和作物产量的影响
Effect of Disturbing Calcic Horizon of Chestnut Soil on Soil Physical Properties and Crop Yield
摘要
Abstract
A field experiment was carried out to explore the effect of disturbing (deep tillage and deep loosening) the calcic horizon on soil water and physical properties and crop yield on chestnut soil.The results showed that the soil became soft and soil hardness decreased for the hard calcic horizon was broke by deep loosening.The soil bulk density was reduced by 0.03g/cm 3 in 0~ 80cm soil layer after deep loosening,then the rainfall infiltration rate and soil water storage capacity was increased,so the crop yield and rainfall use efficiency was increased.关键词
