柱花草高产栽培技术的研究

Study on the cultivated methods of Styiosanthes guianensis

采用随机区组试验,以不同播种方式、不同刈割方式及不同施肥水平对柱花草Styiosanthes guianensis的分枝数及产量的影响进行了分析。结果表明:随2次刈割时间间隔的增长,柱花草分枝数减少。在中等肥力处理条件下,适宜播种方式为撒播15 kg/hm2,2次刈割时间间隔为60 d,施肥模式为:基肥为复合肥600 kg/hm2,农家肥22 500 kg/hm2,不使用追肥,此时,投入产出比最低,经济可行。

By randomized block experiment, the number of ramification and yield of Styiosanthes guianensis in different ways of sowing, cutting and fertilization were studied. The result showed that the number of ramification of S. guianensis were reduced with the increase of time between two cutting treatments. The middle fertility treatment showed the lowest ratio of investment/output and ben- efit. The suitable sowing method was broadcast with 15 kg/hm^2 sowing rate, the period of time between two cutting treatments was 60 d, the way of fertilization was： the basic fertilizer was compound fertilizer 600 kg/hm^2 and dunghill 22 500 kg/hm^2.
