多点测定结果表明,“吨粮田”与低产田的土壤孔隙性、团聚性、持水性及土壤生产力等均有明显差异.在此基础上,提出一些土壤物理性及生产力的量化指标,为改良低产田提供了科学依据.
The result of multi-point measurement showed that there was a significant difference in the soil porosity, reunion, water holding capacity and soil productivity between the “grain fields” and the low-yield fields. Based on this, some quantitative indicators of soil physical properties and productivity were proposed Improve the low yield field provides a scientific basis.
