- Abstract:
- ‘Merlot’ and ‘Cabernet Sauvignon’ were taken as test materials,selenium fertilizers with selenium concentration of 0,100,200,400 and 800 mg·L-1 were set up by field test.The amount of selenium per 667 m2 was 60 L.The effect of selenium fertilizer on the yield,quality and selenium content of grape wine grape was studied at different growth stages of grape,and the optimum period and dosage of selenium fertilizer for selenium rich wine grape were determined,in order to provide raw material for selenium rich wine brewing.The results showed that the single grain weight,transverse longitudinal diameter,soluble solid and vitamin C content of ‘Merlot’ and ‘Cabernet Sauvignon’ could be improved by spraying different concentrations of selenium fertilizer on the leaves of grape fruit at different growth stages,and as the amount of fertilizer increased,it increased first and then decreased.In the period of fruit expansion,the effect was the best when the leaf surface spray was 200 mg·L-1.At this time,the single weight,transverse diameter,longitudinal diameter and vitamin C content of ‘Merlot’ and ‘Cabernet Sauvignon’ increased by 28.6%,15.4%,13.7%,72.6% and 23%,11.85%,12.9%,71.4% respectively.The yield of ‘Merlot’ and ‘Cabernet Sauvignon’ was 10.2% and 9.1% higher than that of the control at the fruit expansion stage when the concentration of selenium was 200 mg·L-1.In the range of safety,the effect of selenium enrichment was the best when the wine grape fruit was treated with 200 mg·L-1.The selenium content of ‘Merlot’ and ‘Cabernet Sauvignon’ seeds,skin and grape berries increased by 342.2%,954.9%,3 311% and 352.3%,1 518.9%，2 818%,respectively,compared with the control.In summary,the optimum spraying time for ‘Merlot’ and ‘Cabernet Sauvignon’ foliage was fruit enlargement,and the optimum spraying concentration was 200 mg·L-1.
