Abstract


Studies have evaluated the golf course greens recipe root zone soil physical properties and traits of lawn to guide the construction of golf course turf has practical significance. Experiment with 13 different recipes with different particle size distribution that is different from the content of peat soil and golf course greens mixed creeping bentgrass, as materials, canonical correlation analysis, regression analysis and other methods to establish a formula lawn soil physical properties and characteristics of each index Recipe ingredients with significant correlation between the regression model to determine the physical properties of soil and lawn traits and recipe ingredients qualitative and quantitative relationship between the obtained formulas soil physical properties of each index optimization formulation program. The main results are as follows: different formulations of soil water holding capacity significantly different, recipes available soil moisture characteristic curve equation y = ax -b fitting. Layer structure, the two-story structure and the three-tier structure, etc. 3 rootzones structure on the formulation has an important impact on soil water holding capacity, root zone layer structure and the total water content of the soil at different depths of the volumetric water content was significantly greater. Compared with the three-tier structure, two-story structure root zone soil water content and the total volumetric water content at different depths are more, of which five full-sandy soil formula (AE) and containing less peat soils (F) in two The total water content of the layer structure and the volumetric water content at different depths were significantly more than the three-tier structure, while others contain more 7 recipes peat soils (GM) in the two-story structure and the three-tier structure of the total water content and volumetric water content at different depths were no significant differences. In addition to handling mixed sieve sift silt clay soil and peat in the fine particles, a significant increase in soil saturated hydraulic conductivity, can make recommendations that do not meet USGA mix of soil physical properties up to standard. The physical properties of different formulations of soil and turf traits were significantly different. Recipe total soil water storage capacity and capillary pores mainly by very fine sand and silty clay (x 3 ) and the content of peat; bulk density and total porosity mainly in coarse sand and peat content related; against saturated hydraulic conductivity affect the order of sand, the coarse sand, peat, very fine sand and silty clay; turf relationship between speed and smaller in coarse sand, but by the other three factors influenced recipes; clippings mainly by the amount of sand and very fine sand and silty clay (x 3 ) Content; June aboveground biomass only by the content of peat; November root biomass is mainly affected by extremely fine sand and powder content of clay and peat. Reviving speed are associated with all recipe ingredients, which by the very fine sand and silty clay content greatest impact; June apparent in coarse turf quality by less affected by the impact of the other three factors are larger; 11 Month apparent mainly in coarse turf quality, sand content related. Physical properties can be screened out of the reach USGA specification golf green root zone soil solution optimized formulation. By adjusting rootzones structure and sieved soil (<0.05mm) treatment, soil material formulations can significantly expand the range of options, indicating that do not meet USGA specification greens recipe soil physical properties was able to compliance, USGA specification can be further improvement.
