Its flower bud is mixed bud and forms in the year before flowering and fruiting, but it is difficult to control the formation of flower bud, and the phenomenon of biennial bearing that influencing the production is prone to appears by poor management.

其花芽是混合芽，形成于开花结果的前一年，但花芽形成控制困难，管理不善很容易出现大小年，影响产量。

The ratio of dry matter distribution to annual branch, biennial branch and capillary root was higher than weeping peach. That to coarse and fine roots was lower than weeping peach. 5.

柱型桃干物质分配到一年生枝、二年生枝及毛细根比例高于垂枝桃，而分配到粗根和细根的比例低于垂枝桃。

At present, the rate of broken biennial root in cutting sugarcane is very high, exceeds more than 20%, and is arriving at 35% when it works in sweat field.

目前切割器切割甘蔗的破头率较大，超过20%，湿地作业达到35%以上。

Higher the rate of broken biennial root is, lower the germination of sugarcane is in the next year, and the output of sugarcane accordingly.

甘蔗破头率高，来年甘蔗发芽率就低，甘蔗的产量相应地就低。

However, there are a lot of factors that affect the cutting quality ( the rate of broken biennial root) of cutter.

而影响切割器切割质量（破头率）的因素较多，因此，有必要对甘蔗切割器影响切割质量的各因素进行优化研究，提高其切割质量。
