采用多头高接换种技术改造枣树,嫁接的接穗多,成活后树冠恢复很快,如把价格低廉的金丝小枣换成市场潜力大的冬枣,1～2年便能大量结果。现把枣树的多头高接换种技术要点介绍如下: 1.采集接穗,及时贮藏 采集接穗要选择丰产树上部比较健康粗壮,生长允实、芽较饱满的无病虫害枝条。不能采下部徒长枝和幼树上的枝条作接穗。接穗采集后若不能
The use of multi-head high exchange technology to transform jujube tree, scion and more grafted surviving crown recovery quickly, such as the low price of gold jujube into the market potential of jujube, 1 to 2 years will be able to produce a large number of results. The jujube tree is now a new high-alternate technology points are as follows: 1 collection of scion, timely storage and collection of scion to choose the upper part of high yielding trees healthy and sturdy, growth allows real, bud full of pest-free branches. Can not be taken under the branches and young saplings branches scion. If scions can not be collected
