板栗嫁接在新梢生长期进行,可随采集接穗随嫁接,免去冬春采集大量结果母枝(接穗),经过贮藏保鲜等手续,延长了嫁接时期,具有投资少、效率高、简便易行等优点,一般成活率达90％以上。 1.嫁接时期:燕山地区在5月下旬至6月上旬,即新梢停止生长至雌花初期进行。嫁接时期过晚新梢已全部木质化影响成活;过早新梢生长量少未木质化、枝嫩易风干成活率低。 2.采集接穗:选用早丰、燕魁、燕短枝等优良品种。采集半木质化、枝粗0.4厘米以上的发育枝。用中间壮芽部分、去掉基部瘪芽部分和顶端细嫩枝以及叶片、保
Chestnut grafting in the shoot growth stage, with the scion with the grafting with grafting, eliminating the need to collect a large number of winter and spring results of the parent branch (scion), after storage and preservation and other procedures, extending the grafting period, with less investment, high efficiency, simple and easy And other advantages, the general survival rate of 90% or more. 1 grafting period: Yanshan area in late May to early June, that is, the new shoots stop growing until the early female flower. Grafting too late shoots have all the impact of lignification survival; early growth of young shoots less lignification, easy to dry branches and easy to survive low. 2. Collection Scion: Selection of early abundance, Yan Kui, Yan spur and other fine varieties. Collection of semi-lignified, branches thick 0.4 cm above the development of branches. With the middle part of the strong buds, buds to remove part of the bud and the top of fine shoots and leaves, Paul
