Effect of Rain Shelter Cultivation and Light Supplement Measures on Characters of'Sunshine Rose'Grape
This article used the'Sunshine Rose'grape as the experimental material to compare the effects of rain shelter and open field cultivation modes on the'Sunshine Rose'grape.The results showed that the'Sunshine Rose'grape introduced in southwestern Shandong could bloom and bear fruit normally in open field cultivation,with good adaptability and stress resistance.The disease susceptibility rate of plants under rain shelter cultivation had significantly decreased,with a 10.6％decrease compared to that under open field cultivation.After the use of LED white light supplementation measures,the yield and quality of grape cultivation under rain shelter significantly improved,with a 14.1％increase in yield per 666.7 m2 compared to open field cultivation,and the soluble solid content,titratable acid content,and solid acid ratio were 0.22％,-0.02％,and 2.92％higher than those in open field cultivation,respectively,aiming to provide new ideas for'Sunshine Rose'grape planting.
