| 摘 要： | 对渭北旱原红富士苹果进行了不同生育期不同处理喷施钙肥研究,结果表明,钙肥能有效提高红富士苹果的产量和品质,并能降低果实的发病率和储藏烂果率,尤其以盛果期喷施硝酸钙加奈乙酸处理的产量、硬度、含糖量、维生素C分别比对照增加86.50%、9.99%、31.8%和47.84%,发病率仅为6.7%,烂果率也低于对照72.97%,果实的氯离子和硝酸根离子也低于对照。由此可见,苹果施用钙肥应以叶面喷施为主,盛花期喷施效果最佳。

| 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(NO_3)_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 NO~(3-) was also lower than CK.Therefore,it is most ideal to spray calcium fertilizer in flourishing flower phase. |
