| Abstract: |
| The experiment was conducted to study the effects of spraying calcium fertilizers at different growth phase on Red Fuji apple in Weibei dryland.The results showed that calcium fertilizers could efficiently increase the yield and quality of Red Fuji apple,and reduce the rate of disease and rotting rate of stored fruits.The effects of the treatment of spraying Ca(NO3)2+NAA at flourishing flower phase were most remarkable,under which the yield,hardness,sugar content and vitamin C were increased by 86.50%,9.99%,31.8% and 47.8% respectively compared to CK,the rate of disease was only 6.7%,the rotting rate of fruits was 72.97% lower than CK,and the content of Cl-and NO3- was also lower than CK.Therefore,it is most ideal to spray calcium fertilizer in flourishing flower phase. |
