以盛果期‘长富二号’苹果树为试材,比较了改良十字形和主干疏层形树形的结构,以及2种树形对结果个数、单株产量、总产量、果实大小、可溶性固形物含量、果实着色、优果率、商品果率的影响。结果表明,改良十字形树形的单株产量和总产量与主干疏层形基本相同,但1级、2级大个果实比率、可溶性固形物含量、良好着色率、优果率、商品果率远远高于主干疏层形树形。 Taking the apple tree of “Chang Fu II” in full fruit stage as test material, the structure of improved cruciform and sparsely layered tree shape was compared, and the results of two tree types on the number of fruit, yield per plant, total yield, fruit size , Soluble solids content, fruit coloring, excellent fruit rate, the impact of commodity fruit rate. The results showed that the yield per plant and the total yield of improved cruciform tree were basically the same as those of the main stratosphere, but the ratio of the first grade and the second grade of large fruit, soluble solid content, good coloring rate, excellent fruit rate, Much higher than the trunk sparsely layered tree.
