草种混播技术在草坪建植中的应用

Application of mixture turfgrass in establishment

探讨了 2个混合草种在上海的引种适应性 ,3年的试验结果表明 ,混合草种的密度、绿度、抗热性均优于单一草种 ,具有更好的综合表现 ,更强的抗逆性 ,适于在草坪建植中应用。

year-experiment result showed that density, greenness and resistance to heat of mixture turfgrass were superior to that of single turfgrass. Key words:mixture turfgrass; adaptability of inducing; turf establishmentABSTRACT The report made use of the electron microscopy technology to examine the sick Pagrosomus Major at Qingdao in 1995 expounded, a lot of sphereovirus particles which were found in the cytonucleus and cytoplasm of tissues of hepar, gut, kidney and grill. Study result showed: the sphereovirus had an irregular inclusion body in cytonucleus and cytoplasm at all, whose diameter was between about 80-100nm.The virus particles had a middle density nucleus with an envelope. In diseased cells, nuclear chromatin changed and formed virus inclusion body,and part of the nuclear envelope was dissolved and distributed a lot of ribosome's over the cytoplasm, part of the outer membrane and crest of mitochondrion were out of shape and dissolved.
