夏季水分管理对梨橙果实发育和产量品质的影响

干旱缺水是导致果园低产、低效的主要原因之一。重庆三峡库区降水丰沛,但水资源在时空上分布很不均匀,许多坡地果园水源紧缺,季节性干旱十分突出。2002年7月至2006年1月,通过用叶片水分亏缺与果实膨大相关性的研究以及水分管理模式,对柑橘生长和发育的影响进行试验研究,总结出了一套适合坡地柑橘园的水分管理模式。

Study of the Effects of Water Management in Summer on Development and Quality of 'Licheng' Orange

Drought is one of the main restriction factors for citrus production. The precipitation is abundant in Chongqing,but water resource distribution variates in seasons and regions. We carried out the research from July 2002 to January 2006,and studied the relationship between water deficit of leaf and the development of fruit. And the effect of water management pattern during the development of citrus was also studied. A water management model for hilly citrus orchards in the hot and dry valleys was established based on the research.
