在果树矮化密植栽培中,有以下几种方法使果树变矮:①利用矮化砧或矮化中间砧;②采用紧凑型品种;③采用致矮的农业技术;④使用生长调节剂。现仅用矮化砧为例,分析一下矮砧果树变矮的原因: 什么是矮化砧木具有矮化作用的砧木,叫矮化砧。矮化砧具有比其接穗细胞渗透势低的生物学特性。由于细胞的渗透势与溶质浓度成反比,所以,矮化砧组织细胞渗透势低而细胞液浓度较高。通过嫁接后,将与其接穗细胞形成浓度的逆生理差。
In the fruit tree dwarf close planting cultivation, there are several ways to make fruit trees shorter: ① use dwarfing an dwarf or dwarfing anvil; ② using compact varieties; ③ using induced short agricultural technology; ④ the use of growth regulators. The dwarfing anvil is only used as an example to analyze the reason why the dwarf ancestors are dwarfing. What is the dwarfing rootstock that has the dwarfing rootstock called dwarfing anvil? Dwarfing anvil has biological characteristics that are less invasive than its scutellum. As the cell’s osmotic potential is inversely proportional to solute concentration, dwarfing anaerobic tissue cells have low osmolality and high concentrations of cytosol. After grafting, it will form an inverse inverse physiological difference with its scion cells.
