| 摘 要： | 以10年生苹果为试材,研究了不同程度改形对树体光合能力及果实品质的影响。结果表明,改形后随每hm2留枝量的减少,光合作用加强,净光合速率提高,净光合产量增加,果实品质提高;但改形过重,留枝量过少,净光合产量有下降趋势,果实品质提高不明显。对间伐果园,改形以隔2株伐1株,抬干60～80cm,每株留枝量650～700最好;对不间伐果园,以抬干80～100cm,每株留枝量350～550为佳。冬剪改形后留枝量以60万～90万/hm2较为适宜。 |

| Abstract: | The effects of modifying tree form on photosynthetic ability and fruit quality were studied with 10-year-old Red Fuji apple/M26.The results showed that the photosynthesis strengthened,the net photosynthetic rate rose,the net photosynthetic yield increased and the fruit quality improved with reducing of shoot number per hm2.However,if tree forms were modified heavily,the shoot number per hm2 left less,there was a decreasing tendency with the net photosynthetic yield and the improvement of the fruit quality was not distinct.The first iea on modifying tree form was cut one every two trees,major low branches kept 60-80 cm high,and good to keep 650-700 shoots per tree.Otherwise,the major low branches should keep 80-100 cm high and the shoots number keep 350-500 per tree for intermediate cutting.After modifying tree form,it's better to keep 600-900 thousand shoots pre hm2. |
