The results showed that RF, SF and RSF could increase the fresh fruit yield compared with CF and decrease the water content of grapes, increase the absorption of nitrogen,phosphorus and potassium in leaves,reduce the residue of nitrate nitrogen in one meter soil profile.SF and RSF could significantly increase soil available potassium residue in 60 cm soil profile.Among them,RF was the best fertilization mode,which increased the fresh weight of grape fruit by 3.1%,decreased the moisture content by 1.0 percentage points,increased the absorption of nitrogen,phosphorus and potassium of leaves by 13.9%,22.7%,14.0%,increased the absorption of potassium of fruit by 2.5%,decreased nitrate nitrogen residue in 1-meter soil by 16.4%,and decreased available phosphorus and potassium residues by 16.6% and 12.7% in 60 cm soil profile.Therefore,reasonable reduced fertilization can not only reduce fertilizer input and production cost,but also increase grape yield and nutrient absorption,reduce soil nutrient residue,and can be applied in production.

The total sugar content and the activities of acid invertase(AI),neutral invertase(NI),sucrose synthase(SS) and sucrose phosphate synthase(SPS) were determined by physiological and biochemical methods.The results showed that the“厂”-shaped tree shape was beneficial to the accumulation of glucose,fructose and sucrose in‘Cabernet Sauvignon’ grape,fructose and sucrose in‘Chardonnay’grape,and fan-shaped tree shape was beneficial to glucose accumulation in‘Chardonnay’ grape.However,the total sugar contents of ‘Cabernet Sauvignon’ and ‘Chardonnay’grape were higher in the shape of fan than in the shape of “厂”.Tree shape had significant influence on AI and SPS activities of ‘Cabernet Sauvignon’ grape,and the difference reached significant level at the color transformation stage and mature stage. The AI activity of the“厂”-shaped tree shape was higher than that of the fan-shaped tree shape,and activities of NI,SS and SPS in the shape of fan were better than that in the shape of “厂”.The activities of AI,NI,SS and SPS of ‘Chardonnay’grape in the fanshape were better than those in the shape of “厂”.The tree shape of fan was more beneficial to the accumulation of total sugar and the increase of enzyme activity in wine grape.The tree shape of “厂”was more beneficial to the accumulation of glucose,fructose,and sucrose in‘Cabernet Sauvignon’,and the accumulation of fructose and sucrose in ‘Chardonnay’.

The principal component analysis of the fruit quality of Beimei grape showed that the first principal component contained the contents of peonidin-3-O-glucoside, delphinidin-3-O-glucoside, total soluble sugar,cyanidin-3-O-glucoside,the second principal component contained the contents of titratable acid and petunidin-3-O-glucoside.The comprehensive score of fruit quality of Beimei grape with different leaf-fruit ratio treatment was the highest in T3 treatment,followed by T4 treatment,and the lowest in T1 treatment.Therefore,in order to ensure the grape yield,it is suggested that the leaf-fruit ratio of grape plant should be adjusted to 22 leaves/panicle,so as to improve the anthocyanin content in the pericarp and fruit quality of Beimei grape.

The yield loads of four treatments were one cluster per two（F1），three（F2），four（F3），and five（F4）shoots，respectively，and yield load of one cluster per shoot was the control（CK）.The fruit quality during the delayed harvest and the nutrient storage of branches after defoliation were compared.Results showed that the berry softening rate and soluble sugar content increased gradually，the berry weight，hardness and titratable acid（TA）content decreased gradually，and the total soluble solid（TSS）content and ratio of TSS and TA increased first and then decreased during the delayed harvest time.The berry softening rate and the soluble sugar content of branches decreased gradually，the decline rates of berry weight and hardness slowed down，and the contents of nitrogen，phosphorus，potassium and starch in branches increased gradually with the yield load level decreasing. The berry softening rate of all treatments reached about 50% at 63 days after fruit ripening.At 42 days，42 days，49 days，63 days and 70 days after fruit ripening，the berry weight of CK，F1，F2，F3 and F4 decreased significantly compaired with that at ripening. The fruit soluble sugar content of F2 was always the highest，which reached 22.06% at 77 days after fruit ripening.In order to obtain better economic benefit，it is suggested that the suitable harvest time is about 45 days after fruit ripening（mid⁃October）for Shine Muscat under the condition of rain⁃shelter cultivation in the old flooded area of Yellow River，and the yield load is from 6.25 t/ha to 7.50 t/ha，that is one cluster per three shoots based on the fruit quality and nutrient accumulation of branches.

Results showed that berry russet occured in the intercellular space and cell wall first，and the cell structure became obvious. Then it spreaded into the cell gradually. Meanwhile，the browning range and cell space increased，and the peel surface was uneven.It penetrated into the whole cell when berry russet was severe. With the increase of berry russet level，the permeability of cell membrane increased gradually.The cell membrane permeability of berry russet levels 3 and 4 increased significantly，which reached above 77%.Meanwhile，the contents of cellulose，hemicellulose and protopectin decreased gradually，and the contents of lignin and total phenol increased gradually. And the contents of lignin and total phenol at berry russet levels 1，2，3 and 4 increased significantly，which reached 161. 3 mg/g and 1.29 mg/g or above，respectively.Furthermore，the activities of cellulase and acid phosphatase increased first and then decreased with the increase of berry russet level.The activities of alkaline phosphatase and peroxidase decreased first and then increased.The activity of phenylalanine ammonia‐lyase increased gradually.The polyphenol oxidase activity decreased gradually.In conclusion，the formation of berry russet in Shine Muscat grape is a process of the degradation of cell wall structure and the accumulation of lignin and other berry russet substances.The phenylalanine ammonia‐lyase is the key enzyme to regulate the formation of berry russet of Shine Muscat grape.
