不同设施栽培方式对刺五加采摘期及产量的影响

Effects of Different Protected Cultivation Methods on Picking Time and Yield of Acanthopanax senticosus

为了加强对刺五加资源的保护、扩大资源量,本研究采用大棚、中棚、小棚等设施栽培方式对养生保健型蔬菜刺五加进行促早栽培试验,以提高设施栽培的经济效益。试验结果表明:刺五加大棚种植在株高、茎粗、冠幅和根长方面表现较好,综合研究认为大棚栽培对刺五加采摘期的提早效果最好,比露地提前30 d以上。运用设施栽培刺五加,大棚增产1350 kg/hm2,中棚增产1050 kg/hm2,小棚增产750 kg/hm2。扣除设施成本后,大棚覆盖栽培的效益最好,增效为9.375万元/hm2,中棚增效5.737万元/hm2,小棚增效2.400万元/hm2。

In order to strengthen the protection of Acanthopanax senticosus resources and expand the amount of resources,this project adopts big shed,middle shed,small shed and other facilities cultivation methods to promote the early cultivation experiment of Acanthopanax senticosus,to improve higher economic benefits.Experimental results showed that Acanthopanax senticosus covering planting was better in plant height,stem diameter,crown width and root length.Comprehensive research suggestedthat big shed cultivation had the best effect on the picking time,which was more than 30 days earlier than that in open field.After Acanthopanax senticosus was cultivated with facilities,the yield was increased by 1350 kg/hm2 in greenhouses,1050 kg/hm2 in middle sheds and 750 kg/hm2 in small sheds.After deducting the shared cost of facilities,the best cultivation benefit was achieved by big shed covering,with an increase of 93750 yuan/hm2,57370 yuan/hm2 in the middle shed and 24000 yuan/hm2 in the small shed.
