摘　　要：为获得适应过渡带地区四季常绿的优质草坪,采用早熟禾的不同品种,同一品种采用三个播种梯度交播,在已成坪的杂交狗牙根草坪上进行试验。结果表明,不同处理的出苗及苗期生长状况、坪用性状和草坪质量有一定的差异,应用模糊数学综合评判法评定不同处理草坪质量,初步确定,采用早熟禾品种自由2号、交播量为20 g.m2的处理,其综合评判值最高,为0.779 5。In order to obtain high quality evergreen lawn in transitioual climatic zone, under earlier period research foundation, different varieties of Poa pratensis L. were seeding in established lawn of warm-season hybrid Bermudagrass, meanwhile the same variety was conducted in three grades. The results showed that the overseeding techniques were suitable for warmseason lawns established by hybrid Bermudagrass, their adaptability and quality was observed carefully. The growing state in emerge and seedling stage in different treatments was different. The synthetical quality of mixed lawn was assessed by the method of Fuzzy mathematics evaluation. The results indicated that qualities of turf were different among different treatments, and the best overseeding treatment was Freedom Ⅱ with the grades 20g·m^-2 the comprehensive evaluating value was 0.779 5.
