摘要
本文分析了水稻土生态系统的特点及其中作物与土壤系统的相互影响,作物的适种性与土壤供肥性是左右生态系统功能的主要因素,这均与土壤基础肥力水平有密切关系,所以土壤基础肥力水平是运筹熟制的重要依据。 基于热量条件,土壤水文状况与土壤基础肥力的区域差异,讨论了太湖地区水稻土生态分区。
The properties of paddy soil ecosystem and mutual impacts between crop system and soil condition were analyzed. Crop aaaptaomty and fertilizer supply, the main two factors determining the functions of the ecosystem, arc closely related to soil property. Based on regional variation of heat condition, soil hydrology and soil fertility, the rcgionalhation of paddy soil ecosystem in Taihu lake region has been discussed.
