以13种高尔夫球场果岭配方土壤为材料,比较了一层结构、二层结构、三层结构等3种坪床结构对配方土壤水分特性的影响,用通径分析方法分析了各种配方成分对总含水量的效应。结果表明:全沙配方土壤总含水量及不同深度的体积含水量显著较少,泥炭、极细沙和粉粒粘粒含量越多,含水量越大。三种高尔夫球场果岭坪床结构中,一层结构的总含水量及不同深度的体积含水量显著较多。与三层结构相比,二层结构的总含水量及不同深度的体积含水量均较多,其中5个全沙配方土壤(A-E)及含泥炭较少的土壤(F)在二层结构中的总含水量及不同深度的体积含水量均显著较三层结构多,而其它含泥炭较多的7个配方土壤(G-M)在二层结构和三层结构中的总含水量及不同深度的体积含水量差异不显著。通径分析表明,中粗沙和泥炭是影响配方土壤总含水量的主要因子;细沙和极细沙及粉粒粘粒是影响配方土壤总含水量的次要因子。
The effects of three types of flat bed structure, including one-story structure, two-story structure and three-tier structure, on soil moisture characteristics of the formula were compared by using 13 types of golf course green formula soil. Through the path analysis method, Effect on total water content. The results showed that the total soil water content of the whole sand formula and the volume water content at different depths were significantly less. The more the contents of peat, fine sand and silt, the more the water content. In the three types of golf courses, the total water content of one-layer structure and the volumetric water content at different depths are significantly higher. Compared with the three-layer structure, the total water content of the two-layer structure and the volume of water content at different depths are more, of which five full-sediment soil (AE) and soil with less peat (F) in the two-story structure The total water content and the volumetric water content at different depths were significantly more than the three-layer structure, while the total water content of seven other formula-bearing soils (GM) The difference of volumetric water content is not significant. Path analysis shows that medium and coarse sand and peat are the main factors that affect the total soil moisture content of formulated formula. Fine sand, ultra-fine sand and grit are the secondary factors affecting the total soil moisture content of formulated soil.
