一、引言果树隔年结果习性已在过去的园艺学文章中叙述过了,并被认为是不理想的事。隔年结果对商品生产和业余种植的果树都是一个重要的经济问题。苹果的大小年比梨的严重,对晚熟品种和早熟品种有同样的重要性。由于选用了现代砧木和树形,又由于果园栽培管理技术大为提高,目前,西欧隔年结果问题比1940年之前少多了。核果类果树没有明显的隔年结果现象。我们知道,有特别明显隔年结果习性的苹果品种有:较老的荷兰品种Brabantse Bellefleur和Zoete Campagne、老的德国品种Johannes Bottner、英国品种Miller’s Seedling、现代品种Benoni和Laxton’s Superb。虽然现代品种在总种植面积中所占比例很小,但其果实品质好,收益大。
I. INTRODUCTION The following year’s results of fruit trees have been described in past horticultural articles and are considered to be undesirable. The results of the following year are an important economic issue for both commercial production and amateur fruit trees. The size of an apple is more severe than that of a pear and is equally important for late-maturing and precocious varieties. As a result of the selection of modern rootstocks and trees, and because of orchard cultivation and management techniques greatly improved, at present, Western Europe, the results of the next year than before 1940 less. Stone fruit trees there is no obvious second year results phenomenon. We know that there are apples that have a particularly distinct year-by-year result: the older Dutch breeds Brabantse Bellefleur and Zoete Campagne, the older German breed Johannes Bottner, the British breed Miller’s Seedling, the modern breed Benoni and Laxton’s Superb. Although the proportion of modern varieties in the total area planted is very small, but the fruit quality is good, the benefits are large.
