桂林地区轮作与非轮作条件下水稻土收缩变化研究
【目的】研究不同耕作条件下水稻田土壤收缩变化,为防治土壤收缩产生裂隙以及水稻安全生长提供理论依据及指导。【方法】以水稻田为研究对象,在轮作与非轮作条件下,利用van-Genuchten修改方程得到的土壤收缩曲线模型对不同土壤含水量条件下的水稻田原状土壤进行土壤线性伸展系数变化和土壤收缩曲线拟合的研究。【结果】土壤收缩特征曲线拟合值和原状土壤样品实测值拟合度高（R~2〉0.97）;在轮作条件下,土壤黏粒含量大于非轮作,而土壤孔隙度却与之相反;轮作与非轮作条件下,土壤线性伸展系数都随土层深度的增加而减小,0~8 cm土层和18~26 cm土层土壤收缩曲线呈现＂S＂型,在40~46 cm土层非轮作区...
