应用花枝水培、盆栽试验等方法,确定出杏不同品种的自然休眠结束期,依此为基础,根据0℃～7.2℃模型,结合当地气象资料,测算出不同品种的需冷量,杏的需冷量为860～910h。这为各地科学合理地确定适宜扣棚时间提供了依据。
Based on the 0 ℃ ~ 7.2 ℃ model and the local meteorological data, the different cold tolerance and apricot of different varieties were calculated based on the methods of hydroponics and pot experiment. Required cooling capacity of 860 ~ 910h. This provides a basis for scientifically and reasonably determining the appropriate time for deduction.
