| 摘 要： | 在日光温室内研究了高硝态氮营养环境下,分别喷施微量营养元素钼、锰、硼、铁、锌对砂培韭菜叶片硝酸盐含量及植株生长的影响。结果表明:叶面喷施钼或硼均可显著降低韭菜的硝酸盐含量,降幅达20.4%~32.4%,但未发现有提高韭菜生物量的作用;叶面喷施锰或铁均显著降低了春季韭菜的硝酸盐含量,降幅分别为14.7%和13.9%,且显著提高了韭菜植株的生物量,植株鲜重分别增加了17.6%和13.3%,干重增加了17.3%和18.1%;在秋冬季低温时期增施钼可提高韭菜叶绿素含量。

| Abstract: | The present investigation was carried out under solar greehouse conditions,to study the effect of micronutrient foliar application on plant growth and nitrate content of Chinese chive while the seedlings was irrigated with nutrient solution of high level nitrate nitrogen in sand culture.The micronutrient used in this experiment included molybdenum(Mo),manganese(Mn),boron(B),iron(Fe),and zinc(Zn).The results showed that the nitrate content in Chinese chive leaves was significantly decreased by foliar applica... |
