本试验旨在研究金红密植(不同密度)的效应及不同密度的树体丰产参数。该试验获得了八年生密植金红折合亩产4387kg的高额产量。证明在加强綜合管理的前提下密植可以早结果、早丰产、充分利用光能,显著的提高单产、提高经济效益、增强植株间的群体保护作用。为了稳产、优质,必须根据不同密度控制负载量、枝量、树高、冠径、叶面积系数、叶果比。通过综合比较分析最佳密度为2×4米以及变化型密度1×3米(当6—7年生时,间伐成2×3米保留一株移走一株)。
The purpose of this experiment is to study the effect of dense planting density of gold and red (different densities) and the tree yield parameters of different densities. The experiment received a high yield of 4387kg of eight-year-old planting gold red yield per mu. Proved that in the strengthening of integrated management under the premise of planting can be early results, early high yield, make full use of light, significantly improve yields, improve economic efficiency and enhance the role of group protection among plants. In order to stable and high quality, we must control the load, branch quantity, tree height, crown diameter, leaf area coefficient and leaf-fruit ratio according to different density. Through comprehensive comparison and analysis, the optimal density is 2 × 4 meters and the variation density is 1 × 3 meters (when 6-7 years old, thinning to 2 × 3 meters to retain one strain to remove one strain).
