球场长草区原有草种为冷季型草种中的草地早熟禾，长草区坪床以原始黏土为主，排水通透性较差，夏季温度较高时草坪病、虫、草害比较严重，需要投入大量人力及物流力成本进行养护，加上球场水资源非常紧缺，球场改造时，长草区我们重新选用了抗病虫草害能力更强、耐旱性更好、养护成本更低的暖季型草种中的中华结缕草。夏季高温时段草坪病、虫、草害较原有草地早熟禾草坪大幅减轻。同时，因为中华结缕草在威海地区从9月中下旬至5月上旬基本为休眠期，真正的生长期仅有4个月，加上在无修剪状态下自身不会长地太高这一特点，所以全年长草区修剪频次较原有草地早熟禾草种也大幅减少，这样在长草区草坪修剪方面投入的人力、油料、设备维修等成本都大大减少了。

The original grass species used in the rough area of the course was a cool-season grass species. The grass bed in this area was mainly clay, with poor drainage and permeability.
Recently we reverted to Chinese knotweed, a warm-season grass that is more resistant to pests and diseases, more drought-tolerant and less costly to maintain. During the hot summer months, the grass is much less susceptible to disease, insects and weed damage than the original grass, Early Grass. Also, because Chinese knotweed is dormant from mid to late September to early May in Weihai, the true growing season is only 4 months.
