| 摘 要： | 研究了温室黄瓜植株叶片养分含量和土壤养分状况,并探讨了植株叶片养分吸收与土壤养分之间的关系。结果表明：6个温室大棚中的黄瓜植株叶片氮含量明显低于临界值,磷含量偏高,而钾含量适宜,Fe、Mn、Cu和Zn含量丰富;土壤氮、磷、钾养分严重不平衡;叶片磷含量与土壤速效磷含量呈极显著正相关,叶片钾含量与土壤缓效钾和速效钾含量呈显著正相关。叶片中的磷、钾含量可作为土壤肥力指标。 |

| Abstract: | The nutrient contents of cucumber leaves and soil in greenhouse were studied,and the relationship between nutrient absorption of leaves and soil nutrients was discussed.The results showed that the content of N of cucumber leaves in six greenhouses was lower significantly than the critical value,that of P was higher,that of K was suitable,and there were high contents of Fe,Mn,Cu and Zn.The contents of N,P and K were severly unbalance.There was a significantly positive correlation between the content of P in leaves and that of available P in soil,and there was a positive correlation between the content of K in leaves and the contents of slowly available K and available K in soil.The contents of P and K in leaves could be used as the soil fertility index. |
