摘要
通过花生盆栽砂培试验 ,研究不同钾肥处理对花生萌发、出苗和生长发育的影响 ,分析不同钾肥对花生造成的毒害原因。结果表明 :在低水平 ,K2 SO4处理的效果比 KCl好 ;而在高水平 ,KCl处理的效果比K2 SO4好。对同一种钾肥 ,均随着施钾量的增大 ,花生受到的毒害作用也越大。但以 KCl处理毒害更重 ,发生毒害的时间也提前。两种钾肥处理均以施 K2 O1 .0 g/kg砂水平为最佳。在生产上低水平施用 K2
A sand pot culture experiment was carried out to study the effect of different potassium treatments on seed germination and seedling growth ,and analysed the poisonous reason of potash fertilizer in peanut. The results showed that the effect of K 2SO 4 treatment was better than that of KCl treatment with lower potassium level, but the effect of KCl was better than that of K 2SO 4 with higher potassium level.The poisonous degree increased with the increase of potash fertilizer.The poison of KCl treatment was more severe and its poisonous time occured early.The treatments of KCl and K 2SO 4 with K_2O 1 0 g/kg were best,indicating that it is safe to use lower K_2SO_4 fertilizer in practice.
