摘要
调查了粉红佳人和长富2优质高产苹果园的树体和群体结构参数。结果表明:株行距3 m×4 m的果园,粉红佳人666.7m2产量4 400 kg时,单株留枝量为1 071条,枝类组成以中枝、叶丛枝为主,其次依次为长枝、短枝,发育枝所占比例最小;长富2 666.7m2产量5 000～6 200 kg时,单株留枝量为966～1 745条,枝类组成以短枝、中枝和叶丛枝为主,其次为长枝,发育枝所占比例最小;多数新梢只有一次生长,二次生长新梢比例较少;果园叶面积系数为2.7～3.9,果园覆盖率为79.3%～100%。
Taking Pink Lady and Fuji Nagafu No.2 as materials,the high yielding and good quality tree and population structural parameters were researched.The results showed that in the orchard with the spacing of 3 m in the row and 4 m between rows,when the yield of Pink Lady was 4 400 kg per 666.7m2,the reserved shoots per plant was 1 071,which consisted mainly of middle shoots and phyllome shoots followed by long shoots,short shoots and the least of developing shoots.When the yield of Fuji Nagafu N0.2 was 5 000～6 200 kg per 666.7m2,the reserved shoots per plant reached 966～1 745,which consist mainly of short shoots,middle shoots and phyllome shoots,followed by long shoots and the developing shoots.Most shoots only grew one time.The leaf area index was 2.7～3.9,and the coverage rate was 79.3%～100%.
