我国江西、福建等省,以前做过不少有关硫磺、石膏等硫肥试验,并反应了一定的增产效果.但这些试验一般都集中在冷浸型水稻土上,作物是水稻.对于冷浸型土壤施硫增产的原因及机理,现在还不十分清楚,通常只是从土壤化学和土壤环境作一些解释.本文主要研究南方非冷浸型土壤几种母质的供硫能力和硫肥效应,观察一些作物的缺硫症状,并探讨土壤中硫与植物硫的关系.
China’s Jiangxi Province and Fujian Province have done a lot of tests on sulfur fertilizers such as sulfur and gypsum before, and have responded to some stimulation effects, but these tests are generally concentrated on cold-soaked paddy soils and the crop is rice. The reason and mechanism of soil sulfur production increase is not yet clear, and usually only from the soil chemistry and soil environment to make some explanations.This paper mainly studies on sulfur supply capacity and sulfur fertilizer effect of several parent materials in non-soaked southern soils, Sulfur deficiency symptoms in some crops and discusses the relationship between sulfur and plant sulfur in soil.
