闽北2013年气象条件对红地球葡萄生长及品质的影响

Effects of meteorological conditions on the growth and quality of Red Globe Grape in northern of Fujian in 2013

通过对闽北2013年红地球葡萄花序明显减少、开花不整齐,全市70%的红地球葡萄减产、品质下降原因和田间管理的分析表明:花序原始体分化期和花器官分化期的气象条件是导致葡萄花序原始体分化期和花器官分化期缩短,引起原始体分化不充分、花器官分化不良,以及2013年花量少、花穗减小、开花不整齐的主要原因;而前期多雨、少光照是引起霜霉病、炭疽病、白腐病等病害暴发或流行,以及后期7月中旬后气温高、降雨少,部分果园出现旱兆或夏旱,是果实品质下降的主要原因之一。

The causes of infLorescence decreased,irreguLar bLossom,reduction of output,decLine in ＆#232;uaLity of 70%Red GLobe Grape and fieLd management were anaLysed. The resuLts showed that the meteoroLogicaL conditions at infLo-rescence primordium differentiation stage and fLoraL organ differentiation stage were the main causes for shortening of infLorescence primordium differentiation stage and fLower organ differentiation stage,insufficiency in originaL body dif-ferentiation,unheaLthy in fLoraL organs differentiation,and aLso for the fLower number and spicas decreased,irreguLar fLowering in 2013. Moreover earLy rainy and Less Light resuLted in outbreak and epidemic of downy miLdew,anthrac-nose,white rot and other diseases. High temperatures and Low rainfaLL after mid JuLy were one of the main causes of fruit ＆#232;uaLity decLine.
