【摘要】:[目的]為合理利用農(nóng)業(yè)氣候資源,主動適應(yīng)氣候變化提供依據(jù)。[方法]基于寧夏銀川地區(qū)1961-2015年地面氣象觀測資料,明確了釀酒葡萄生長季內(nèi)主要農(nóng)業(yè)氣候資源、影響釀酒葡萄品質(zhì)的主要農(nóng)業(yè)氣候因子及主要農(nóng)業(yè)氣象災(zāi)害的演變特征。[結(jié)果]近55年銀川日平均氣溫穩(wěn)定通過10℃起始時間提前,結(jié)束時間顯著推遲,日平均氣溫穩(wěn)定通過10℃持續(xù)時間顯著增加,每10年分別增加97.6℃和2.6d,尤其是1995年后積溫出現(xiàn)了明顯增加。近55年釀酒葡萄適宜的放條出土?xí)r間提前,可能的生長季呈顯著延長趨勢,生長季內(nèi)熱量資源顯著增加。近55年釀酒葡萄全生育期內(nèi)日照時數(shù)呈顯著減少趨勢,生育期內(nèi)日較差均呈不顯著的減少趨勢,但在釀酒葡萄適宜生長范圍內(nèi)。最熱月(7~8月)平均氣溫顯著增加,每10年增加0.28℃,不利于釀酒葡萄優(yōu)良品質(zhì)的形成。釀酒葡萄采收前1個月(9月)降水量及降水日數(shù)表現(xiàn)為增加趨勢,對品質(zhì)形成不利。不同級別霜凍及越冬凍害發(fā)生頻率有所減少。[結(jié)論]熱量資源增加為晚熟品種的成熟提供了保證,但是霜凍及越冬凍害依然不容忽視。
[Abstract]:Objective to provide evidence for rational utilization of agricultural climate resources and active adaptation to climate change. [methods] based on the surface meteorological observation data from 1961 to 2015 in Yinchuan area of Ningxia, the main agroclimatic resources, the main agroclimatic factors affecting the quality of wine grape and the evolution characteristics of main agrometeorological disasters in the growing season of wine grape were determined. [results] in recent 55 years, the starting time and ending time of Yinchuan daily mean temperature stable passing through 10 鈩,
