[Result] The results showed that the content of water-soluble salt and EC value in greenhouse soil was significantly higher than in the open field, and the content of tot.

[结果]大棚土壤中水溶性总盐含量与电导率(EC)比露地蔬菜土壤明显增高,且随栽培年限的延长总盐含量与EC值逐渐升高,水溶性总盐与EC值在0-10cm土层呈线性正相关,R2=0。

The results suggested that EC value was decreased, micro organism community was improved obviously; the rate of withering was reduced; the growth of cucumber was promoted, the obstruction of plastic house soil was released under three treatments.

试验结果表明 :3种处理下 ,土壤全盐含量 (EC值 )均下降 ,微生物区系得到明显改善 ,黄瓜枯萎病减轻 ,促进了黄瓜生长发育 ,达到了缓解大棚土壤连作障碍的目的。

92,which shows that the soil is alkaline;②The average pH value of the 0~10 cm surface layer soil from Fuyang Road and the 10~30 cm surface layer soil from Shouchun Road are close to the pH value of the control,however,the average pH value of the other soil samples is significantly higher than that of the control;③ The average EC value of the soil is from 21.

92,表现为碱性;②除寿春路和阜阳路0~10 cm表层土样、阜阳路和蒙城路10~30 cm深层土样的pH平均值,与对照土样的pH值比较接近外,其他土样pH平均值都明显高于对照样的pH值;③除了芜湖路0~10 cm表层土样、蒙城路和芜湖路10~30 cm深层土样的EC平均值与对照样比较接近外,其他的土样EC平均值都比对照土样的EC值高出21。

Effects of N Application Rates on Yield,Nitrate Accumulation of Lettuce and EC,pH Value of Soil;

氮肥施用量对生菜产量、硝酸盐积累及土壤EC值、pH值的影响

The Influence of Appling Organic Materials in the Continuous Cropping Soil on the Soil pH and EC Value and Microbe;

施用稻草等有机物料对黄瓜连作土壤pH、EC值和微生物的影响

The results show that greater proportion of reclaimed water irrigated,greater EC value and lower pH value of soil water extract appeared in farmland and ditch cross-section.

研究发现:再生水灌溉量占总灌水量的比例越高的区域,农田和农沟断面处的土壤浸提液的EC值越大,pH值则越小。
