以无灌溉条件生长在丘陵地上的 8年生红富士苹果树为试材 ,探讨了树盘内埋罐节水渗灌的生理生产效应 ,结果表明 :树盘埋罐渗灌明显增加了新梢长度、短枝叶叶面积、叶绿素含量、光合和蒸腾速率 ,提高了树体的水分利用效率和果实的单果重、糖 /酸比 ,降低了果实的可溶性固形物和含酸量。如果埋罐结合施肥 ,所测定的各项形态和生理指标均显著高于单独埋罐处理 ,果实品质也得到了改善。另外 ,各种处理还不同程度地提高了叶片和果实某些矿质元素的含量 ,降低了果实的N/Ca比。
The 8-year-old Red Fuji apple tree grown on the hilly ground without irrigation condition was used as the test material to study the physiological effect of water-saving infiltration irrigation on the tree trunk. The results showed that: , Short leaf area, chlorophyll content, photosynthesis and transpiration rate increased the water use efficiency of tree and fruit weight, sugar / acid ratio, decreased the soluble solid content and acid content of the fruit. If buried cans combined with fertilization, the measured morphological and physiological indicators were significantly higher than the individual buried cans, fruit quality has also been improved. In addition, various treatments increased the content of some mineral elements in leaves and fruits to some extent, and reduced the N / Ca ratio of fruits.
