摘要
以8年生岳阳红/平邑甜茶苹果为试材,研究了每667 m^(2)产量2 000、2 500、3 000 kg等3种负载量对树体结构、叶绿素、光照强度、果实品质的影响。结果表明:每667 m^(2)产量2 500 kg,枝量69 139个,长中短枝比例1∶2∶7,较合理;叶绿素含量和比叶鲜重随着负载量的增加先增加后降低;树冠内相对光照强度60%~80%占比在70%以上,强光区和弱光区比率较低,有利于花芽分化和优质果的形成;果面光洁度好,易着红色,果实硬度、可溶性糖含量、可滴定酸含量适宜,品质优于其他处理。
Taking Yueyanghong/Malus hupehensis apple 8 years as experimental material, the effects of three kinds of loading loads on tree structure, chlorophyll, photosynthetic index and fruit quality were studied, the three treatments are2 000 kg/667 m^(2), 2 500 kg/667 m^(2) and 3 000 kg/667 m^(2). The treatment 2 500 kg/667 m2with medium load had good internal and external fruit quality, which contributed to the nutrient accumulation, high yield and stable yield of the tree. The number of shoots was 69 139 per 667 m2, and the ratio of long, medium and short branches was 1∶2∶7;with the increase of load,chlorophyll content and specific leaf fresh weight first increased and then decreased;the effective relative light intensity of treatment 2 500 kg/667 m^(2)reached more than 70% from 60% to 80%, the proportion of strong light area and weak light area is low, which is beneficial to flower bud differentiation and high-quality fruit formation;good fruit surface finish, easy to turn red, suitable fruit hardness, sugar and acid, and its quality is better than other treatments.
