Effects of different ground mulch types on the berry quality of Marselan wine grape and comprehensive evaluation
[Objective]To study the effects of different ground mulching types on the berry quality of wine grape Marselan.[Methods]Five-year old grafted Marselan/SO4 was taken as test materials,clean till-age one as the control to study the effects of inter-row spaces of the vineyard covered with black geotextiles(BGM)and inter-row spaces of the vineyard with natural growing grass(GM)on Marselan grape quality.[Results]The results showed that cluster weight,berry weight,longitudinal diameter and transverse diameter were increased by ground mulch.Wilting percent of BGM was the highest,with 5.45%,juice yield was the lowest(32.89%),there was no wilting percent for GM,juice yield was significant higher for GM than CK.Soluble solid and reducing sugar content were decreased for BGM and increased fur GM.BGM and GM de-creased titratable acid and pH,but increased sugar/acid.Total phenol,flavonoids,flavanols and tannins con-tent in fruit peel were significantly increased for BGM and GM,anthocyanins content in peel were changed,but there was no difference.FRAP and ABTS antioxidant activity for BGM and GM were increased,but DPPH antioxidant activity for BGM and GM were significantly decreased.The correlation analysis of 26 berry quality indexes showed that there were significant positive or negative correlations,with correlation coefficients ranging from-1.00 to+1.00.[Conclusion]In turpan,grass mulch can be selected as a new model of wine grape cultivation.
