摘要
本文通过调查贵阳二环林带种植的凯特杏、李、沙梨和石榴4种经济果树的种植密度、胸径和单株产量,寻找出各树种的产量--密度和密度--胸径的相关关系,并选用一元一次方程对其相关性进行拟合,找出不同果树的最佳种植密度,为它们在生产上夺取高产、稳产提供依据.
Cultivation densities, breast - height diameter of stem and production in 4 different fruit trees have been investigated. Correlation among production, cultivation density and breast - height diameter of stem are described. The correlation is expressed as y =f（X）, y = a ＋ bx. According to these, we can find optimum cultivation density of different trees and provide proof for high and stable production.
