Abstract

Abstract: According to the observed data of edaphic humidity in Suizhou from 1991 to 2013, the local annual distribution of edaphic humidity, soil moisture distribution in different layer and suitable soil moisture of main crops were analyzed. The results show that, the annual variation of edaphic humidity is about five main stages and is regular. Both no precipitation and heavy rainfall cause a conspicuous influence for edaphic humidity. The increasing or decreasing of soil humidity will have a big impact on crops and agriculture.

Key words: edaphic humidity, soil moisture, annual variation, Suizhou city
