影响锥栗嫁接成活率的几个因子

Influence Factors on Graft Survival of Chinquapin

以锥栗6个类型16个单株为接穗,野生锥栗、板栗、大果锥栗、麻栎为砧木,选择不同立地条件地块,研究影响锥栗嫁接成活率的因子。结果表明,不同锥栗品种类型、嫁接时间、砧木、圃地条件、剪砧方法对锥栗嫁接成活率均存在较大影响。嫁接时间以秋季9月底到10月上旬和春季萌芽前1个月最好;宜选择排水良好的山脚梯田;在芽萌动时离接芽25 cm处第1次剪砧,接芽抽出20~25 cm后在其上部2 cm处第2次剪砧最好;砧木宜用野生锥栗及本砧,板栗、麻栎不适宜作锥栗砧木。

In order to study influence factors on graft survival of chinquapin （ Castanea henryi （Skan） Rehd. et Wils. ）, taking passing primary 16 individuals of 6 type of chinquapin as scions, taking native Qing Yuan native chinquapin （ Qing Yuan county gold Chinese chestnut）, Chinese chestnut , big fruit chinquapin, Ma Li etc. as stocks under different garden conditions. The results showed that those all influenced graft survival, including chinquapin type, grafting time, stock, garden field condition, method of cutting scion and so on. The proper graft time was from the end of September to the first ten-day of October in autumn, and one month before bud in spring. Terrace with good drainage condition was good selection. It is necessary to cut at 25 cm near the bud firstly, then cut at 2 cm near the bud after drawing out 20 - 25 cm. The native small chinquapin and free stock were equal to stock, Chinese chestnut and Ma Li was not suit for stock.
