多方试验综合得到不同品种全生育期丰年指标:早熟品种积温>3050℃,降水400—600mm;日照时数>1030小时。中、晚熟品种相应增加积温200℃,降水50mm,日照时数100小时.欠年比丰年相应积温少100℃,日照少6O—70小时,降水差150—200mm.胶东目前种植方式气候条件满足程度较高,渤海湾沿岸受干旱威胁,鲁北热量欠缺,鲁南降水过多,光照不足。
Multi-party trials to get the full year of different varieties of richness indicators: precocious varieties of accumulated temperature> 3050 ℃, precipitation 400-600mm; sunshine hours> 1030 hours. Middle and late varieties corresponding increase accumulated temperature 200 ℃, precipitation 50mm, sunshine hours 100 hours.Year than the corresponding accumulated temperature less 100 ℃, sunshine less 6O-70 hours, precipitation is poor 150-200mm.Jiaodong current planting climate conditions to meet the degree Higher, the coast of Bohai Bay threatened by drought, Lubei lack of heat, excessive rainfall in Lunan, inadequate lighting.
