Abstract

Abstract: Gravitation ecology is a new research field developed in the recent two years:This paper attemptsto explain the effects of gravitation ecology on the productivity of farmland ecosystem by analysisof the dynamic variations in environmental factors and productivity of farmland ecosystem alongthe east-west section of the Haihe River(from Taihang Mountain to the gulf of Bohai Sea).Itaims to help for the overall management of farmland ecosystem and regional agricultural development.

Key words: soda-alkaline soil, oat, salt stress, K⁺/Na⁺, absorption selectivity
