通过对板栗实生大树高接营建板栗采穗圃配套技术研究,内容包括:高产接穗良种板栗采穗圃园地选择;采穗圃选用的良种应与砧木嫁接亲和力强,发枝力、成枝力强,耐修剪;大树高接技术;接后栽培管理;培养高产枝量树形;田间管理。良种板栗采穗圃快速营建,应选立地条件较好,密度采用2 m×3 m、2 m×4 m可获得理想接穗产量。其中2 m×3 m密度可产接穗21 645个/667 m2穗段。
Through the chestnut tall tree construction of chestnut picking high-matching technology research, including: high-yield scion elite chestnut scion garden selection; picking sprouts selected varieties should be grafted with rootstock affinity, hair force, branch force Strong, anti-pruning; tree high access technology; then cultivation and management; cultivate high-yield branch tree; field management. Quick planting of seed chestnut nursery garden should be selected site conditions are good, the density of 2 m × 3 m, 2 m × 4 m to obtain the desired yield of scion. Among them, the density of 2 m × 3 m produced 21 645/667 m2 spikes.
