摘要
为探索黔草4号鸭茅在贵州气候条件下的最适宜播种期,开展了5个不同秋播期对其株高、鲜草产量、干鲜比和叶茎比影响的试验。结果表明,在贵州中海拔地区尽量提早播种不仅可使刈割次数增加,还可以提高鲜草产量,且干鲜比和叶茎比均较高;黔草4号鸭茅的最佳播种期在9月中旬,其鲜草产量可达75 000 kg/hm^2以上。
In order to determine the optimum sowing date of Qiancao NO.4 cocksfoot under the climatic condition of Guizhou, the effect of 5 different fall sowing dates on plant height, fresh yield, ratio of dry weight to fresh weight and the leaf stem ratio was investigated. The results showed that the cutting frequency was increased by early sowing as possible, the fresh yield was increased and the ratio of dry weight to fresh weight and the leaf stem ratio were both higher. The optimum sowing date of Qiancao NO.4 cocksfoot was in the middle of September and the fresh yield exceeded 75 000 kg/hm2.
