| 摘 要： | 试验采用５因素二交正交旋转组合回归设计，对柱花草高产栽培的综合农艺措施进行研究，并建立了千物质产量与种植密度，收割次数、施过磷酸钙量、施复合肥量、喷施钼酸铵浓度先进５项农艺措施之间的数学模型，通过模型解析和寻优，得出在试验条件下，５项农艺措施对热研２号柱花草产量影响的程度依次为：收缩次数〉种植密度〉复合肥量〉施过磷酸钙量〉喷施钼酸铵浓度，并得出高产栽培组合方案。

| Abstract: | Field test was conducted by quadratic orthogonal regression design. A regressive model between the dry matter yield of Stylosanthes guianensis cv. Reyan No.2 and cultural variables included plant density, cutting frequency, superphosphate application rates, compound fertilizer application rates and spraying concentration of ammonium molybdate was built. After analysis and optimization, it was concluded from the model that based on the extent of the effects of the variables on forae yields their order as follows: cutting frequency>plant density>compound fertilizer application rates>superphosphate application rates>spraying concentration of ammonium molybdate. Cultural pratcices for high forage yield in S.guianensis cv. Reyan No.2 was recommended. |
