- Abstract:
-
The effects of different water-nitrogen on photosynthetic characteristics and the quality of red Fuji apples were studied. The results indicated that photosynthetic characteristics of the Fuji apples changed with the different water and fertility treatments and appeared obvious phenomenon of the midday depression. Middle water and high nitrogen, high water and nitrogen treatments can keep the photosynthetic with certain effect. The treatment of the low water and middle nitrogen combination was the lowest and had the best effect of the water conservation. Under the moderate water, applying more nitrogen can enhance Gs and benefit of photosynthesis. The best scheme of fertilizer and water management were 5250 m3/hm2 of irrigation water, 600 kg/hm2 of nitrogen, which could obtain higher quality performance.
