不同海拔高度对半野生栽培猪苓产量的影响

Study on the Yield Effect of Growing Semi-wild Polyporus umbellatus at Different Altitudes

以当地野生灰苓和人工培养的蜜环菌材为材料,采用海拔高度为600～800、800～1 000、1 000～1 200和1 200～1 400m的4个栽种范围,随机区组设计,研究猪苓半野生栽培的适宜海拔高度。结果表明:猪苓栽种在海拔高度800～1 200m产量与经济效益均较好;栽种在海拔高度1 000～1 200和800～1 000m林区的猪苓产量显著高于1 200～1 400和600～800m的产量,其经济效益高近1倍。因此,猪苓半野生栽培时,建议在海拔高度800～1 200m范围内的丘陵地区栽培。

lhking local wild gray Polyporus umbellatus and cultured Armillaria as the material,the appropriate altitudes of semi-wild cultivation of Polyporus umbellatus were selected by cultivating areas ranging from 600-800 m,800-l 000 m,1 000-1 200 m to 1 200-1 400 m. The results showed that the yield and economic benefit of Polyporus umbellatus planted at 800- 1 200 m altitude were better than the other groups. The yield production of those growing in forest area at 1 000-1 200 m,and 800-1 000 m altitudes were significamly higher than that of 1 200-1 400 m and 600-800 m altitudes, with nearly doubled economic benefit. Therefore,the suitable cultivation area of semi-wild Polyporus umbellatus should be within the scope of hilly areas at 800-1 200 m altitude.
