以黑宝石李为材料,采用不同的整型修剪方法,对不同树型的株高、地径、冠幅和产量进行了调查,研究了不同整型修剪方式对黑宝石李冠幅和产量的影响。结果表明:在供试验条件下,采用拱棚形整型修剪,亩产最高,三年平均亩产达4074.8 kg/667 m2。采用拱棚形修剪,果园的通风、透光性好,果实着色好,外形美观,优质果率超过80.00%。
Taking black plum Li as material, different pruning methods were used to investigate the plant height, diameter, crown width and yield of different tree types. The effects of different pruning methods on crown width and yield of black gem influences. The results showed that under the conditions of the experiment, the arch-shaped pruning was the best, with the highest yield per mu in three years reaching 4074.8 kg / 667 m2. The use of arch-shaped pruning, orchard ventilation, good light transmission, fruit coloring, good appearance, high-quality fruit rate of more than 80.00%.
