滨海盐碱地区土壤渗透系数普测及改良措施

通过对天津开发区绿地进行普查表明，土壤渗透系数小（在１×１０－ ６～ｎ×１０－ ７ ｃｍ ／ｓ范围内），是植物生长不良的主要原因。必须掺拌改变土壤结构的物质，才能提高土壤通透性，达到种植土的要求。

Determination of Soil Permeability and the Soil Improvement in Shore Saline Region

TEDA is located in Bohai shore ,the land in this region is formed by the modern sea regression.The soil is clay and structure is very bad.The soil permeability is very low by the determination of the green land ,is 1×10 -6 ～n×10 -7 cm/s,and that is the reason that the plants grow bad.The soil must mix into other materials that reform the soil structure.
