| 摘 要： | 研究了钾、钙和硅的混合喷施对番茄叶片中的可溶性糖和水溶性总酚含量的影响。结果表明:叶面喷施钾溶液及其与钙和硅溶液的搭配使用均可显著提高叶片中可溶性糖的积累量,分别增加了68%和129%,即钾、钙和硅溶液同时使用的效果最显著;而对于水溶性总酚含量,叶面喷施钾溶液的效果最好,显著地高于其它处理,其次是混合喷施钾、钙和硅溶液,显著高于对照处理,2个处理分别比对照增加了10.1%和5.2%。

| Abstract: | The effect of KHCO3,amino acid calcium and Na2SiO3 on the content of soluble sugar and total soluble phenolics in tomato leaves were investigated.The results showed that the content of soluble sugar were increased with the single or compound application of K,Ca,Si.There was a significant relationship between the compound application of K,Ca,Si and other treatments,the next was the single application of K,which were 129% and 68%.higher than that of control respectively.As for the total phenolics,the content ... |
