红叶石楠营养钵扦插繁殖技术

The Cutting Reproduction Technique on the Culture Pans of Photinia fraser

以红叶石楠为试材,选取生长粗壮、半木质化1a生枝条,进行春季和秋季扦插,对插穗用"国光生根粉"进行蘸根处理,采用一个营养钵扦插2～3个插穗的育苗技术。基本上10～12个月即可达到出圃要求,成活率可达92%～98%,高度可以达到50～80cm,有5～8个分枝,并有一定的冠幅,苗齐苗壮,根系发达,带钵移栽根系完整,不伤苗,保水保肥,便于长途运输,移栽后相对于未使用营养钵育苗的成活率可提高10%～20%,且生长速度快。价高易销,上市很受欢迎。

This experiment collected the strong and semi-lignified branch of one year age from the Photinia fraser,the following techniques were adopted to breed the seedlings,the spring and autumn cuttings,to treat the cutting slips with the root-dipping technique with ＇Guoguang powder＇,the seedling-breeding technique with 2~3 slips in one culture.These seedlings whose survival percentage could reach to 92%~98% and a height of 50~80 cm,and they also could meet the transportation demand in 10~12 months.There were 5~8 branches in each seedling with a big canopy and strong root system.The transplantation with culture plates had a whole root system,reservation to the water and fertilizer,convenient to the long-distance seedlings transportation and a 10%~20% higher survival percentage comparing to the seedlings with the ordinary seedlings.Besides that,these seedlings were popular because of their high speed of growth,high price and a good marketing feedback.
