摘  要：
采用土壤物理性质测定、土壤化学分析方法,研究了吉林省玉米高产土壤肥力特性。结果表明:吉林省玉米高产土壤与一般土壤在肥力体型与肥力体质方面均存在明显的差异;在肥力体型上主要表现在高产土壤1 0～10 0mm的颗粒比例、总孔隙度、通气孔隙度、渗透速度、自然含水量、田间持水量、毛管含水量等方面明显高于一般土壤,而土壤容重明显低于一般土壤;在肥力体质上主要表现在高产土壤有机质、速效氮、速效磷、速效钾、速效锌的含量明显高于一般土壤。

摘  要：
Specific property of highyielding soil fertility for maize in Jilin province was studied, by soil physical property determination and the analytic method of soil chemistry The result showed that in Jilin province, there were obvious differences in fertility build and fertility constitution between the highyielding soil and general soil for maize In the fertility build for the highyielding soil, the granular rate of 10～100 mm, total porosity, aeration porosity, percolation rate, natural water capacity, field water capacity and capillary water holding capacity all exceeded those of the general soil, but bulk density was lower In fertility constitution for the highyielding soil, the content of organic matter, available N, available P, available K, and available Zn were higher than those of the general soil
