Effects of amino acid fluid fertilizer on yield and quality of Shatangju

The field experiment was carried out to study the application effect of amino acid fluid fertilizer on Shatangju. The results showed that applying amino acid fertilizer solution was more effective, the chlorophyll content of leaf, fruit diameter and fruit number per plant improved by 5.8%~20.3%, 6.7%~16.3% and 54.4%~95.7%, respectively. In a word, the yield of Shatangju increased by 10.4% 41.6% compared with the treatment of commercial fertilizer appling. The Shatangju applied with fluid fertilizer had better fruit quality, the contents of soluble sugar and solid were higher than those of control, while the organic acid was lower than control.
