摘要
2005-2007年在泡泡幼树上进行环割、拉枝开角试验,结果证明:拉枝开角60°可明显缓和树势,降低发枝部位,增加有效枝量和有效花数量,促进泡泡树早实丰产。
A study was made of ring incision and trimming the branches on little pawpaw in 2005 to 2007.The results showed that ring incision is no effect on pawpaw and opening angle of 60 ° of trimming the branches can significantly relax trees、depress parts of wattle,and increase efficient branches and the number of flowers to promote the pawpaw high yield early.
