板栗是扦插生根十分困难的树种。笔者经过四年研究,探索出嫩枝扦插繁殖技术,生根率稳定在80％以上,生根质量好,数量多。现将主要技术环节介绍如下: 1.建立采穗圃 选择排水良好、土壤疏松肥沃的地块,定植一年生的板栗实生苗,建立采穗圃,定植的株行距0.3米×0.8米,也可用幼龄实生苗作采 Chestnut root cutting is very difficult species. After four years of research, the author explored the technology of cutting propagation of softwoods. The rooting rate was stable at over 80%. The rooting quality was good and the quantity was high. Now the main technical aspects are described as follows: 1. To establish a pickpockets Choose well-drained, loose and fertile soil plots, planting annual chestnut seedlings, the establishment of mining garden, planting row spacing 0.3 m × 0.8 m, can also be used Age seedlings for mining
