山楂幼树枝量与对面积的相关性以６年生‘大金里’山楂品种为试材，测定了两种栽植密度（４ｍ×４ｍ，２ｍ×２ｍ）下的单株枝量与叶面积，分析结果表明，单株枝量与叶面积呈高度正相关，经显著性检验、误差分析等证明，可以由单株枝量来估测叶面积。上述两种栽植密度下的... The correlation between the amount of young branches and the area of ​​hawthorn Six-year-old ’Daijinli’ varieties of hawthorn were used as materials to determine the branch number and leaf area under two planting densities (4m × 4m, 2m × 2m) The results showed that the branch number per plant was highly positively correlated with the leaf area. After significant tests and error analysis, it was proved that the leaf area per plant could be estimated. The above two planting density ...
