摘  要:
利用正交试验研究了不同刈割周期、施肥水平对5种臂形草属牧草产量的影响。结果表明:刈割周期和草种对产量的影响显著;施肥处理对产量影响不大;各因素对产量的影响为RC>RA>RB,即刈割周期>品种>施肥量。极差分析得出各因素的最优水平为:品种——杂交臂形草;施肥量——30t/hm2;刈割周期——90d。

摘  要:
The effect of different application rates of fertilizer and cutting period on yield and quality of Brachiaria Grisebach was observed. There was no evident yield difference between the treatments of fertilizer application. The yield and quality of Brachiaria were found obviously different between the treatments of cutting period and Brachiaria species. The effect of the three factors on yield of Brachiaria was in the order of cutting period > species > fertilizer. The maximum difference analysis of the resulting data showed that the best cutting period was 90 days, the best species B. hybrid, and the optimum fertilizing rate 30 t/ha.
