| Abstract: |
| The aim of the present work was to evaluate the effects of different cultivation system including conventional cultivation (CK, spacing 5 m×2 m, 999 trees·hm-2) and wide and narrow row planting (WN, spacing 2 m, wide row 4 m, narrow row 1 m, 1 998 trees·hm-2) on light intensity distribution, and the content of sugar and acid components, yield per hectare, and fruit quality of ‘GaiLiangBaiFeng’ peach. The results showed that compared with CK, WN allowed the light to be evenly distributed. Under CK, the light was mostly distributed in the top layer and the light intensity in the lower portion was less than 20%. However, it was over 40% in the middle and lower layers under WN. In 2011, 2012 and 2013, it was found that the yield of peach was significantly improved by WN and the yield per hectare was 31.3%, 41.0% and 33.1%, respectively, higher than that by CK. The sucrose content and sugar acid ratio were significantly increased by WN, but the malate content was decreased significantly. Therefore, WN not only could improve canopy light intensity in the tree, but also could enhance the yield and quality of fruit, demonstrating that WN may be an ideal way of cultivation. |
