腐植酸钾对栽培五味子钾素含量及果实品质影响的研究

试验结果表明：腐植酸钾处理和硫酸钾 磷酸二氢钾处理下相比，五味子植株钾素含量差异不显著，相比对照处理钾素含量差异极显著。五味子果实在腐植酸钾处理和硫酸钾 磷酸二氢钾处理下相比对照果实中各种有效成分含量明显增加，并且腐植酸钾处理效果好于硫酸钾 磷酸二氢钾处理，对栽培五味子果实品质有明显改善作用。

Study on the effect of potassium content and fruit quality of Schisandra chinensis under potassium fertilizer

The experimental results showed that compared to those not applied by potassium fertilizer,the potassium content and all kinds of effective ingredient of Schisandra chinensis were enhanced obviously.While there is no significant difference between potassium contents of the two treatments applied by potassium humate and by potassium sulphate plus potassium dihydrogen phosphate.The contents of all effective ingredients applied by potassium humate were higher than those applied by potassium sulphate plus potassium dihydrogen phosphate.Fruit quality of cultivated Schisandra chinensis was improved significantly.
