自50年代末黄河故道地区开始大量种植苹果,到现在已近30年历史,并已成为我国六大苹果商品生产基地之一。从栽培而论,发展初期研究的主要课题是如何提早结果和早期丰产,继而研究高产稳产的途径和措施,但对如何提高苹果品质方面的工作相对做得较少,加强这一方面的试验研究已日趋必要。 一、黄河故道地区的气候特点及其对苹果品质的影响
Since the late 1950s, large quantities of apples began to be planted in the old course of the Yellow River. Now it has nearly 30 years of history and has become one of the six major apple product bases in China. From the perspective of cultivation, the main research topics in the early stage of development are how to get early results and early high yield, and then to explore ways and measures of high and stable yield. However, relatively little work has been done on how to improve the quality of apples, and the experimental studies in this respect should be strengthened It is increasingly necessary. First, the climate characteristics of the old course of the Yellow River and its impact on apple quality
