双切嫁接对板栗春接成活率的影响

采用劈接、切接、三刀切接及作者创造的新方法─—双切接四种嫁接方法进行板栗春接对比试验，嫁接成活率分别为６５．２％、７２．０％、８１．２％、９２．８％。通过对嫁接后不同日期萌芽株数、嫁接成活率、成活初期抽梢长度、当年抽梢长度、粗度进行统计分析，双切接明显优于其它三种嫁接方法，嫁接部位愈合状况也比其它三种方法好。

湖桑春接夏栽育苗技术探讨

我市培育湖桑苗木以起接为多数。通常起接都是春接春栽,也就是春季嫁接好后,随即栽到苗圃地里,或嫁接后将嫁接体作短期贮藏,待伤口愈合后即栽植。湖桑春接春栽育苗大都在3～4月进行。此时用来栽植嫁接体的苗圃地,一般是各季留茬的空白地,或是将未成熟的夏熟作物割去后作为苗圃地。为不影响夏熟收成。

月季冬接窖藏春栽快速育苗新技术

月季繁殖常用野蔷薇嫁接育苗,嫁接繁殖比扦插成苗快,枝接又比芽接成苗快。“利用砧木效应”花开的早、开的大,是商品苗的主要繁殖方法。为加快育苗速度,通过嫁接生产,革新传统的嫁接操作方法和季节时间,并充分利用冬闲季节,将砧木掘起,在室内进行裸根硬枝嫁接,进行窖藏春?..
