本文分析比较了“金冠”苹果自然扇形与生产上普遍应用的疏散分层形两种树体结构。通过调查树冠内光照分布情况,测定光合强度、称量百叶重、计算生产部位体积、投影面积指数及其各自的果实产量,初步认为:自然扇形结构合理,有利于光照和光能利用,群体产量高,加之整形容易,且有利于机械化栽培,可以在矮密栽培中推广应用。
This paper analyzes and compares the structure of two kinds of trees, which are generally used in natural fanning and production of “Golden Delicious” apple. By investigating the distribution of light in the canopy, measuring the photosynthetic intensity, weighing the leaf weight, calculating the volume of production site, projection area index and their respective fruit yield, it is preliminarily believed that the natural fan-shaped structure is reasonable and conducive to light and light energy utilization, , Together with plastic surgery is easy, and is conducive to mechanized cultivation, can be popularized and applied in the cultivation of low density.
