苹果是多年生作物,如何充分利用土地,提高光合作用的利用率,提高可食部分的比率,达到最大限度的高产稳产,从中找出高产的丰产参数,是当前国内外苹果栽培研究的中心内容之一。根据国内外生产水平,我们认为大面积平均亩产4000斤以上的可视为高产园,亩产在2000～4000斤的为中产园;亩产在2000斤以下的为低产园。丰产参数是指与年年高产有关的一些参考数值。本文是研究苹果地上部分有关生态方面的部分丰产参数。我们调查了辽南10块苹果高产园的实况,从中找出部分丰
Apple is a perennial crop, how to make full use of the land, improve the utilization of photosynthesis, improve the edible part of the ratio, to achieve the maximum yield and stable yield, to find high yield and yield parameters, is the current domestic and international apple cultivation research center one. According to the level of production at home and abroad, we believe that a large-area average yield of 4,000 kg or more can be regarded as a high-yielding garden with a yield of 2,000 to 4,000 kilos per mu for a middle-yielding garden; High yield parameters refer to some reference values related to annual high yield. This article is a study of some of the ecologically important yield parameters of the aerial parts of apples. We investigated the actual situation of 10 high-yield apple-growing parks in southern Liaoning and found some abundance
