不同方法生产草皮的对比试验

本试验以矮生黑麦草为材料 ,研究比较了A :营养土 +种子 ;B :沙层 +营养土 +种子 ;C :三合土 (土壤、锯末、炉渣 ) +种子 ;D :三合土 +尼龙网 +种子四种不同方法在草皮生产中的优劣。结果表明 :四种方法在出苗期、成坪时间、生长速度、颜色、质地方面无明显变化 ,即对坪用性状影响不大。但在草皮性状方面四种处理差异显著。D处理在草皮破损率、撕裂强度、重量方面表现最佳 ,统计结果差异极显著(P <0 0 1 ) ;A处理在这些方面表现最差 (P <0 0 1 ) ;B、C处理界于A、D之间。说明三合土代替土壤和采用隔离层在草皮生产中是完全可行并有必要的。

Contrastive experiment on producing sod with different methode

With lowgrow Lolium perenne L.,four methods used in sod production were compared each other:A.nutritious soil seed;B.sand layer nutritious soil seed;C.three-mixture-soil(a mixture of soil,sawdust and cinder) seed;D.three-mixture-soil nylon net seed.The results showed:all of four treats had no obvious difference in sod Visual Quality such as emergence date,fully developed date,growing velocity,color and texture.But they were very different in sod Functional Quality including torn ratio,tearing intensity and weight.Treat D was the best (P<0.01)and treat A was the worst (P<0.01)and Treat B,C were in the middle.These proved that it was feasible and necessary to replace soil with three-mixture-soil and using isolation-layer in sod production.
