Invetigation On Characters And Load Analysis Of Grape Varieties Introduced Into Yangling

In this experiment,eight wine grape varieties,Sangiovese,Aligote,Beimei,Behong,Beibinghong,Kiralyleanyka,Xuelanhong,Zuoyouhong,and four fresh grape varieties,including the Beauty finger,Golden finger,Summer black,Crimsonseedless were used as the research objects.The botanical characters and economic and biological characters of each grape variety were preliminarily investigated and analyzed.In order to provide basic variety data for the cultivation and research of wine grape in Yang Ling area.and to provide a preliminary basis for the next variety extension.The main conclusions of this study are as follows:Zuoyouhong grape is the best in all aspects of Yang Ling area of Shaanxi province,the fruit is of good quality and suitable for popularization.The fruit characteristics of Kiralyleanyka and Xuelanhong in Yang Ling area are not good overall feeling evaluation.The white variety Aligote performed well in Yang Ling area.Maintain its variety of excellent variety characteristics,suitable for promotion in Yang Ling.The fruit characters of Beimei,Beihong and Sangiovese grape are very good.Fully adapt to the climatic conditions of Yang Ling area,adapt to the planting in this area.The test results show that,Summer black grapes keeping 6-8 clusters per plant was the best treatment considering the yield,which was of a berry load of 891-956 kg/667 m~2.Beauty finger grapes keeping 6 clusters per plant was the best treatment considering the yield the production should be controlled 900 kg/hm~2.Crop load of Golden finger grape should be controlled 8 clusters per plant,whether from the appearance quality,or intrinsic quality point of view,as which was the best treatment considering optimum quality,comprehensive traits and the best economic benefits.Crimsonseedless grapes keeping 10 clusters per plant was the best treatment considering the yield,which was of a berry load of 1561 kg/667 m~2.Among the eight wine grape varieties,Zuoyouhong,Beimei,Beibinghong and Kiralyleanyka grape had 10 clusters per plant.The reasonable yield per mu of the four grape varieties was 414 kg/667 m~2,636 kg/667 m~2 and 563 kg/667 m~2,respectively.Under such loading conditions,both soluble solids,acid content and ear weight are optimal.The reasonable amount of Behong,Sangiovese,Xuelanhong grapes keeping 15 clusters per plant was the best treatment,and the yield per mu was 578 kg/667 m~2,809 kg/667 m~2and 516 kg/667 m~2,respectively.In this case,the fruit quality is not affected and the fruit yield is considerable.
