苹果幼树提早结果,对黄河故道新区大面积发展果树来说,是一个非常重要的问题。提前结果,就是在大面积新植果园里提早生产大量的果品,它不但能提前供应人们所需要的果品,而且还能早日增加经济收益,相应地减少了果园经营投资。1958年大跃进中,故道地区曾经出现了一些幼树早期丰产的果园,创造了提早结果的先例。1959年4月全国果树生产会议上提出了新辟果园早期丰产的号召以后,故道地区很多新辟果园都实现了提前结果。为了总结早期丰产的原因与技术措施,曾进行调查,兹将调查初步结果介绍于下。 Earlier results of young apple trees, the development of large areas of fruit trees in the New Fourth Old Route of the Yellow River is a very important issue. The early result is the early production of large quantities of fruit in a large area of ​​newly planted orchards. It not only provides people with the fruits they need in advance, but also increases their economic benefits as soon as possible and reduces the investment in orchard management accordingly. In the Great Leap Forward of 1958, there were some orchards where early saplings were abundant in the Old Course, setting a precedent for early results. In April 1959, at the National Fruit Production Conference, a call was made to the early harvest of new orchards. Many of the new orchards in the Old Course District achieved early results. In order to summarize the causes and technical measures of early high yield, we conducted a survey and hereby introduce the preliminary results of the investigation below.
