壁饰草毯开发研究Ⅲ养护管理

综合管理技术对壁饰草毯的正常生长十分重要,当按3,6,9 g/m2施用保水剂时,根层饱和持水量分别提高89.2%,106.1%和114.3%,正常生长期延长6,10,13 d;当按0.3%,0.6%和0.9%的浓度喷施植物生长调节剂B9时,草地早熟禾Poa pratensis的叶量依次降低1.8%,9.2%和16.7%,根量相应增加4.4%,7.8%和19.1%.而匍匐翦股颖Agrostis stolonifera相应增加为8.3%,25.0%,41.7%和11.1%,50.0%,83.3%.营养供给以基本基质加菜籽饼水液为佳.其综合长势评价值分别比对照、1号营养液及CO(NH2)2 FeSO4提高42.5%,7.5%,92.5%(对于早熟禾)和131.0%,65.5%,181.0%(对于匍匐翦股颖).

Research and development of grass tapestry on decorative wall III maintenance and management

The comprehensive management technology is very important for ensuring normal growth of grass tapestry. The saturated water holding capacity in roots layer increased 89.2%, 106.1% and 114.3%, respectively, when using 3.0, 6.0 and 9.0 g/m~2 absorbent; correspondingly, the normal growth stage prolonged 6,10 and 13 d. When applied 0.3%, 0.6% and 0.9% plant growth regulator B9 to Poa pratensis and Agrostis stelonifena, the leaf biomass reduced 1.8%, 9.2%, 16.7% and 8.3%, 25.0%, 41.7% respectively; while root biomass increased 4.4%, 7.8%, 19.1% and 11.1%, 50.0%, 83.3%, accordingly. The best nutrition supply was basic substratum mixed with rapeseed cake liquid. The comprehensive evaluation of this treatment revealed that the growth potential of Poa pratensis and Agrostis stelonifera enhanced 42.5%, 7.5%, 92.5% and 131.5%, 65.5%, 181.00%, respectively, compared with control, the nutritious liquid No 1 and CO(NH_2)_2+FeSO_4.
