摘要
通过不同浓度、不同时期和不同方法对烤烟施用Mo6 + 的试验表明 :烤烟施Mo6 + 的协调烟株生理代谢 ,改善烟株植物学性状 ,使烟叶增产、增质。试验各处理以浓度 0 .5g/kg(NH4 ) 6 Mo7O2 4 ·4H2 O在还苗期叶面喷施 1次效果最佳 ,浓度 1.5g/kg(NH4 ) 6 Mo7O2 4 ·4H2 O在团棵期叶面喷施 2次及浓度 2 .5g/kg(NH4 ) 6 Mo7O2 4 ·4H2 O在旺长期根部浇施 1次的效果居第 2位 ,施Mo6 +
The experiment of using different concentration, periods and methods to apply Mo 6+ to tobacco plants was conducted. The results showed that experiment could coordinate the physiology metabolism, meet the nutrition and improve the botany properties, which would result in high yield and quality. The best treatment was the leaves spraying of 0.5g/kg (NH 4) 6Mo 7O 24 ·H 2O at the seedling renew knee high stage one time. The better treatment was the leaves spraying of 1.5g/kg (NH 4) 6Mo 7O 24 ·H 2O at the Knee high stage two times and applying fertilizer of 2.5g/kg (NH 4) 6Mo 7O 24 ·H 2O to the root area at the rapid growth and enlongation stage one time. The tobacco plants applied Mo 6+ got a better quality than those not applied Mo 6+ .
