高海拔冷凉区红地球葡萄开花生物学特性观察

Observation on the biological characteristics of Red Globe grape blooming in high-altitude and cold area

为给高海拔冷凉地区葡萄预防花期灾害、安全生产、保证产量和品质提供参考依据,本试验在高海拔冷凉地区(2450m)观察了红地球葡萄在设施延后栽培(中间露地)条件下的开花生物学特性。结果表明:在高海拔冷凉地区红地球葡萄花期长、开花高峰期在中午12时;设施内开花位置、顺序与低海拔地区有较大差异。

In order to provide a reference for grape flowering disaster prevention, safety production, yield and quality assurance in high-altitude cold area. The biological characteristics of blooming of Red Globe were observed in high-altitude cold area （2450m）, where it was postponed culture in protected field （growing on field in middle period）. The result showed that the blossoming period was longer than low altitude area, blossoming peak was at 12：00 of noon; place and order of blossoming was more different with low altitude area.
