摘要
研究表明在盆景树水无土栽培中,蛭石和砂按1:1混合作基质,树木的生长指标与土栽接近;由于该二种材料均为无机物质,便于清毒处理,可作为外销盆景的栽培基质并适合出口检疫的要求;在上述基质中分树种加入小屑或泥炭对盆景树木的生长是有一定促进作用。任以蛭石和砂为1:1的栽培基质中,施用 NO_3-N:12me·1^(-1),PO_4-P:6.3me·1^(-1),K:9me·1^(-1),Ca:5.4me·1^(-1),Mg:4me·1^(-1)等组成的新配方营养液(1号液),对五针松、真柏和红枫的生长效果优于土栽,而六月雪虽较土栽生长差,但新生枝较2、3号液处理的粗壮。
The results showed that in the soilless culture of potted trees,growth in the mixture of vermiculite and sand at the ratio of 1∶1 used as a culture medium was almost similar with that grown in the soil,For the two materials are all inorganic substances,they are easy for treatment and export quar- antine.The growth of the potted trees was promoted as saw dust or peat was added into the mixture.When the mixture was added with No.1 nutrient solution composed of NO_3-N(12me.1^(-1),PO_4-P (6.3me.1^(-1),K(9me.1^(-1),Ca(5.4me.1^(-1)and Mg (4me.1^(-1),etc.the growth of Pinus parvflora,Sabinu chinensis and Acer palmatum and other potted trees was better than the growth in soil except Serrisa japonica whose branches however,were stronger than those grown in No.2 and No.3 nutreint solitions.
