摘要
通过在黑土、草甸黑土、草甸土 3种不同土壤上连续种植水稻的盆栽试验 ,研究水稻植株吸硫量与土壤无机硫含量的关系 ,以及土壤无机硫下降量的变化规律 ,探讨水稻对土壤硫的吸收规律。研究初步得出 :水稻吸硫量与土壤初始无机硫含量呈正相关 ;土壤中无机硫下降量与土壤初始无机硫含量呈正相关。图 2 ,表 4 ,参 4。
The relation between rice plants absorbing sulphur rate and inorganic sulphur content in soil was studied by pot cultivation test in black soil, meadow black soil and meadow soil The inorganic sulphur variance in soil and the regulation of rice plants absorbing sulphur were analyzed The result showed that there was positive relation between rate of rice plants absorbing sulphur, decreased content of inorganic sulphur in soil and primary content in soil
