表明钾锌配施有较好的互作效应，尤以在灰潮土田上效果最好。

This result shown there was a positive interaction effect of Kand Zn on rice yield , especially on calcareous alluvial .

主要土壤类型中灰潮土缺S状况最为严重，有效S不足的土壤所占比例高达80%。

Among the category of important soils , gray-alluvial meadow soil was the most deficient in sulfur , and the proportion of soil available sulfur being insufficient reached 80 % .

结果表明，在灰潮土上，施用锰肥盆栽试验平均增产27.8%，田间试验增产14.3%，增产效果非常显著，表明该土壤严重缺锰。

The results showed that Mn fertilization significantly increased wheat seed yield by 27 8 % in a pot experiment and 14 3 % in a field experiment on the alluvial soil .

盆栽试验中，同一处理油菜干重生物量和含硫量都表现为黄棕壤>红壤>灰潮土。

To the same treatment in pot trial , dry weight and sulfur content of rape were observed in the sequence : Yellow Brown soil > Red soil > Grey Cultivated Meadow soil .

通过盆栽试验研究了包膜尿素（自制）和尿素等肥料在灰潮土中对芹菜生长、氮吸收、产量和品质等的影响。

Pot experiment was conducted in a glasshouse to investigate the effect of coated urea in calcareous Chao soil on uptake and balance of nitrogen ( N ), yield and quality of vegetable crops .

本体土壤中，好气性细菌总数、耐寒细菌（Psychrotrophicbacteria）、芽孢细菌群在灰潮土中数量分别是砂姜黑土中的47.59、14.62和31.42倍。

There were in grey fluro-aquic soil 47 . 59 , 14 . 62 and 31 . 42 times as many total aerobacteria . psychrotrophic bacteria and spore-forming bacteria in that lime concretion black soil as in bulk soil .

本研究利用盆栽和田间试验，在四川的两个主要土壤，即灰潮土和黄红紫泥上，探讨了锰与钼、铜、硫、氯元素间的交互作用及其对小麦生长的影响。

This study investigated the interactions between Mn and Mo , Cu , S , Cl and the effect of interactions on wheat growth on two manganese deficient soils-a grey alluvial soil and a calcareous purple soil in Sichuan province .

吸附速率顺序为：灰棕潮土>紫色潮土>中性紫色土>黄壤>酸性紫色土。解吸动力学规律与吸附过程相类似。

The order of the maximal amount of Hg ~ ( 2 + ) adsorption was : purple alluvial soil > neutral purple soil > yellow soil > grey-brown alluvial soil > acid purple soil .
