From study of germinated characteristics,per-germination and pressing in four kinds of turfgrass Seeds,the results showed that activity of seedling was ALomium multiforum,Festuca rubra,Festuca arundinacea,poa pratensis L.
对四种草坪草种子进行了萌发特性测定及预萌发和镇压对建坪影响。
Defoliation and soil compaction also reduced the Mycorrhizal colonization of Orchardgrass.
施磷肥、强度刈割和土壤镇压都能显著降低鸭茅(Dactylis glomerata L。
Planting with individual profiling press wheel on drill can provide an optinum soil environment for seeds due to its appropriate compaction and consistent drilling depth.
本文从这一农艺要求出发，在分析单组的受力，镇压轮接地面上的压力分布，力在土壤中的传递规律以及土壤的压实特性的基础上，建立了土壤压密程度与单组使用参数及镇压轮结构参数之间的数学模型，确定了影响土壤压密程度的主要参数以及各参数的适宜范围。
