不同光照条件及混播比例对冷季型草坪草混播质量的影响

Effect of Light Exposure and Cold-season Turfgrass Mixing on Performance of Lawn

摘要

摘要:
目的研究全光照及遮阴条件下，冷季型草坪草草地早熟禾（优美、肯塔基）、紫羊茅（梦神）和多年生黑麦草（轰炸机）与狗牙根混播的草坪质量，比较不同光照条件及混播比例的成坪效果差异，提出适合长春地区夏季混播的草种及组合。
方法通过草坪草外观评价指标，运用隶属函数法及权重法进行综合评价，比较成坪效果差异。
结果在遮阴条件下，多年生黑麦草轰炸机:草地早熟禾优美=1:2效果最好，质量评价分数为0.731；在全光照条件下，多年生黑麦草轰炸机:草地早熟禾肯塔基:普通狗牙根=3:4:3效果最好，质量评价分数为0.396，多年生黑麦草轰炸机与草地早熟禾优美、紫羊茅梦神混播不成坪。
结论在遮阴条件下，两种草坪草混播组合优于含有保护种狗牙根的3个草坪草品种混播组合；在全光照条件下，含有保护种狗牙根的3个草坪草品种混播组合整体草坪质量优于两种草坪草混播组合。

Abstract:
Objective Effects of full light exposure or shading condition and mixing ratio of the cool season meadow grass (Euromyth and K.B.G), Festuca rubra (Rubra), perennial ryegrass (Bomber) and Bermudagrass on the growth and appearance of the lawn were evaluated for turf building in the city of Changchun in northern China.
Method Turf appearance indices on the treatment lawns were compared and evaluated using the membership function method and weights comprehensive evaluation method.
Result In the shade, the mixing ratio of Bomber:Euromyth at 1:2 performed the best with an evaluation score of 0.731. Under full sunlight exposure, the Bomber:K.B.G:Common=3:4:3 combination had the highest score of 0.396, whereas mixing Bomber and Euromyth or Bomber and Rubra would not form an acceptable lawn.
Conclusion The combination of two turfgrasses appeared superior on lawn performance to that of 3-turfgrass containing the protective Bermuda variety in a shaded lot. However, with full sunlight the later were better than the former.
