发展芒果是国家科委在我省攀西地区星火项目的一个内容。目前,攀西地区芒果开发的一个主要问题是苗木繁殖较困难。为此,特介绍一下芒果嫁接繁殖技术,以供参考。一、播种砧木苗:一般用多胚的芒果品种作为砧木。将砧木种子在50℃的热水中浸泡20分钟,以去除病虫害。然后,将内果皮和外种皮去掉。播种时,将种子凸边朝上,浅播于土壤。这样能保证根直立向下生长。去掉弱小苗,保留强壮的实生苗。二、采取接穗:接穗选用直接与砧木干径相似的成熟枝条。在春梢抽发前,芽子开始膨大时采取接穗。若是在其他季节采取接穗,必须先选成熟的枝条,将顶端轮生叶片的叶身或顶端5厘米长内叶片的叶身摘掉。在约2周后,摘掉叶身的叶柄脱落,苞芽开始膨大。此阶段,枝条可用作接穗。芒果的接穗只能 The development of mango is a part of State Science and Technology Commission in our province Panxi area Spark project. At present, one of the major problems in mango development in Panxi is that seedling propagation is more difficult. To this end, special introduction to mango grafting and breeding techniques for reference. First, planting rootstock seedlings: general multi-embryo mango varieties as rootstocks. Soak rootstock seeds in hot water at 50 ° C for 20 minutes to remove pests and diseases. Then, remove the endocarp and outer seed coat. Sowing, the seed convex side up, shallow broadcast in the soil. This will ensure root upright growth. Remove the weak seedlings, keep the strong seedlings. Second, take the scion: scion selection and rootstock dry diameter similar to mature branches. Before the spring shoots are taken, the shoots start to swell and take the scion. If the scion is to be taken in other seasons, mature branches must be selected first to remove the leaf blade of the top leaf or the leaf blade of the inner leaf at the top of 5 cm. After about 2 weeks, the petiole of the leaf body is removed and the bud begins to expand. At this stage, branches can be used as scion. Mango scion only
