阜平山区草莓错季栽培的生物表现及适宜区域

Biological performance and suitable planting areas of unseasonable strawberry in Fuping mountainous region of Hebei Province

通过田间试验和平行观测气象资料,利用地理信息技术和气候要素计算模型,研究了阜平山区种植草莓的生物表现及适宜种植区域。结果表明:在阜平山区种植草莓能够安全越冬、开花、结果,草莓发育期滞后于河北平原,从而达到错季生产的目的;其草莓品质优良,果实中可溶性固形物和维生素C含量均高于河北平原对应的草莓品种;阜平山区错季草莓的适宜发展区域为海拔900～1200m的地区。

Based on field experiment and corresponding meteorological data, and by using GIS and climatic elements-computing model, this paper studied the biological performance and suitable planting areas of unseasonable strawberry in Fuping mountainous region of Hebei Province. The results showed that in study region, strawberry could over-winter, blossom and seed. Its growth period was lagged behind of that in Hebei Plain, and thus, could mature unseasonably. The quality of unseasonable strawberry was excellent, with higher soluble solid and vitamin C contents than those planted in Hebei Plain. The suitable planting areas of unseasonable strawberry in Fuping mountainous region were at the altitudes of 900-1200 m.
