Most plants can make their own food from sunlight, (1) some have discovered that stealing is an easier way to live. Thousands of plant species get by (2) photosynthesizing, and over 400 of these species seem to live by pilfering sugars from an underground (3) of fungi(真菌). But in (4) a handful of these plants has this modus operandi been traced to a relatively obscure fungus. To find out how (5) are (6) , mycologist Martin Bidartondo of the University of California at Berkeley and his team looked in their roots. What they found were (7) of a common type of fungus, so (8) that it is found in nearly 70 percent of all plants. The presence of this common fungus in these plants not only (9) at how they survive, says Bidartondo, but also suggests that many ordinary plants might prosper from a little looting, too.

Plants have (10) relations to get what they need to survive. Normal, (11) plants can make their own carbohydrates through photosynthesis, but they still need minerals. Most plants have (12) a symbiotic relationship with a (13) network of what are called my corrhizal fungi, which lies beneath the forest (14) . The fungi help green plants absorb minerals through their roots, and (15) , the plants normally (16) the fungi with sugars, or carbon with a number of plants sharing the same fungal web, it was perhaps (17) that a few cheaters—dubbed epiparasites—would evolve to beat the system. (18) , these plants reversed the flow of carbon, (19) it into their roots from the fungi (20) releasing it as "payment.\

某新建一级公路土方路基工程施工，该工程取土困难。K10+000～K12+000段路堤位于横坡陡于1:5的地面，施工方进行了挖台阶等地基处理，然后采用几种不同土体填料分层填筑路基，填筑至0～80cm，施工方选择细粒土，采用18t光轮压路机，分两层碾压。两层碾压完成后，检测了中线偏位(合格率90%)、纵断高程(合格率85%)、平整度(合格率85%)、宽度(合格率88%)，横坡(合格率92%)和边坡坡度(合格率90%)，认定土方路基施工质量合格，提请下一道工序开工。
问题

影响土方路基质量最关键的因素是填料和压实，该工程的施工方法对此是否有效控制为什么
