| 摘 要： | 试验采用5因素二次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,并建立了干物质产量与种植密度、收割次数、施过磷酸钙量、施复合肥量、喷施钼酸铵浓度等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:收割次数>种植密度>施复合肥量>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 mode! 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. |
