两种立体A字架结构草莓营养生长特性研究

A Study of Vegetative Growing Characteristics of Strawberry in Two Stereoscopic A Frame

设计2种A字架结构,对各部位草莓营养生长特性进行比较。结果表明:除了第1层外(底层),2种结构其他各层草莓的株高、株径、叶面积、叶柄差异很小,各层次新叶数和叶绿素差异不显著;叶片鲜重、干重、比叶重上层与底层差异极显著;相对含水量5层结构的上层与底层差异显著,4层结构的差异也达极显著水平。认为:适当提高第1层(底层)高度,可以选择5层A字架结构进行草莓立体栽培。

Two stereoscopic A frame were designed to cultivate strawberry.The growing characteristics of strawberry on different position were compared.The result showed that the stem height and diameter,leaf area and petiole in upper tiers and middle tiers had small difference,the new leaf number and chlorophyll had no significant difference in all tiers.Leaf fresh weight,dry weight and specific leaf weight had significant difference between upper tiers and lower tiers.Relative water content had difference between upper tiers and lower tiers of five frame layer and had significant difference with four frame layer.It is suggested to lift the height of the lowest layer and the stereoscopic A five frame was the best to cultivate strawberry.
