In the field experiment of five years in this paper, ecological analysis based on paddy-field rotate system and continuous cropping was studied in the view of soil physical and chemical characteristics, crop output variety, occurring and developing rule of plant diseases and insect pests of farmland, power-flow and state of equilibrium nutrient.
结果表明,与连作耕作制度相比较,在试验设计范围内,稻田轮作系统明显改善了土壤的理化性状,使得土壤随着耕种年限增加,容重下降,而孔隙度增加,固相比率下降,气相比率上升,气液比值增大,土壤通透性大大增强,有效阻止土壤次生潜育化和土壤酸化,提高土壤pH值。
