摘要
探明蓝莓萌芽期气象指标,为蓝莓灰霉病防治提供参考,采用2012年贵州黔东南州蓝莓主要种植区13个样地蓝莓物候期观测资料,结合样地周边自动气象观测站2011年10月1日至2012年4月30日逐日气温资料,研究蓝莓萌芽的气象指标,并进行应用检验。结果表明:蓝莓萌芽前≥7.2℃的活动积温、≥7.2℃的有效积温、≥10℃的活动积温、≥10℃的有效积温均基本恒定;≥10℃的有效积温比≥7.2℃有效积温和≥10℃的活动积温更具稳定性;气候学意义上入冬以后,气温稳定通过10℃终日后≥10℃的活动积温≥195℃·d,气温稳定通过7.2℃终日后≥7.2℃的有效积温≥90℃·d,且连续5d平均气温≥12.3℃即为蓝莓萌芽的气象指标;此时蓝莓进入萌芽普遍期。蓝莓芽开始萌动的下限温度选10℃更好。
In order to provide references for the prevention and control of grey mould disease of blueberry,the meteorological indexes of blueberry germination were studied and tested by using the observation data of phenophase of blueberry in 13 sample plots in the main blueberry growing areas in Qiandongnan Prefecture in 2012,combined with the daily temperature data of the surrounding automatic meteorological observation stations from October 1,2011 to April 30,2012.Results:The active accumulated temperature of ≥ 7.2℃ before germination of blueberry,the effective accumulated temperature of≥7.2℃,the active accumulated temperature of ≥10℃,and the effective accumulated temperature of≥10℃ were basically constant;The effective accumulated temperature of≥10℃ was more stable than effective accumulated temperature of≥7.2℃ and the active accumulated temperature of≥10℃.In winter,the ≥10℃ active accumulated temperature reached ≥195℃ ·d.And the ≥7.2℃effective accumulated temperature was ≥90℃ ·d,constant 5-day temperature of ≥12.3℃ was the meteorological indicator of blueberry sprouting;At this time,blueberry entered the universal stage of germination.The lower limit temperature at which the blueberry buds start to sprout was preferably 10°C.
