金帅苹果高产稳产、果大质优、适应性强,易管理,是欧美许多国家的主要品种,在我国其栽培面积和产量也都占有相当比重。但该品种在我国的大部分地区,特别是在沿海和幼果期低温多湿的苹果栽培区,普遍产生果锈,严重影响果实外观,降低商品价值,成为金帅苹果生产中的一大难题。近年来我们在调查中了解到,肥水管理好的果园金帅果锈比较轻。为了进一步探索土壤和果实营养水平与果锈发生的关系,我们从1990年开始对金帅苹果设区进行了试验研究。现将试验结果总结如下: Golden Delicious apple high yield stable, high quality and good, adaptable, easy to manage, is the main species in many countries in Europe and America, in China its cultivation area and output also occupy a considerable proportion. However, in most areas of our country, especially in low-temperature and wet apple-growing areas in the coastal and young fruit stage, fruit rust is generally produced, which seriously affects the appearance of fruits and reduces the value of the commodities, thus becoming a major problem in the production of the apple. In recent years, we have learned from the survey that the management of fertilizer or water in the Golden Orchard fruit rust is relatively light. In order to further explore the soil and fruit nutrition levels and the relationship between the occurrence of rust, we started from 1990, the apple tree trial set. Now the test results are summarized as follows:
