应用低位嫁接换种新技术,可进行枇杷实生树改造,或品种改良,既可利用原有树砧的根系,迅速恢复树冠,提早结果,又能加速对枇杷果园品种的更新换代。 一、接穗的采集 确保在优良品种上采集接穗,在结果母树上,选生长健壮、叶片浓绿、芽眼饱满、无病虫害、树冠外围中上部的一年生枝条为接穗。采穗前10天左右,去掉母穗枝条上端幼嫩部分或花穗,促进腋芽饱满。 接穗最好随采随用,剪穗应在晴天露水于后进行,剪下的接穗应立即剪去叶片和末端幼嫩部分,仅留短叶柄护芽,剪后应立即用塑料薄膜包裹,并挂上标签,注明品种、日期、地点,接穗用塑料薄膜包裹放
Application of low grafting for a new technology, loquat can be made of real tree transformation, or species improvement, both the root system can be used to restore the crown quickly, early results, but also accelerate the replacement of loquat orchard varieties. First, the collection of scions to ensure that good varieties in the collection of scion, the results of the mother tree, choose robust growth, dark green leaves, buds full, no pests, the crown of the upper middle branch of the annual scion. 10 days before heading, remove the top part of the eldest shoots or spikes to promote full axillary buds. Scion with mining with the best, cuttings should be carried out in the sunny dew in the scion should be cut immediately cut the leaves and the end of the young part, leaving only the short petiole protect buds, cut immediately after the plastic film wrapped and Hang the label, indicate the species, date, location, scion wrapped in plastic film
