The experiment aimed to determine the optimal cutting frequency for desho grass to maximize dry matter yield and forage quality. Three cutting intervals (30, 45, and 60 days) were tested in a randomized complete block design with four replications. The agronomic parameters, dry matter yield, and chemical composition of the grass were collected and analyzed via standard procedures. The cutting frequency significantly affected the agronomic parameters and chemical composition but did not affect the DM yield. The tallest plants and most leaves were observed at 60-day intervals, while the tiller density was greater at 30 days. A relatively high DM yield (8.64 t/ha) was obtained by cutting desho grass at 30-day intervals, which was comparable to the results of the other treatments. The crude protein content decreased with increasing intervals, whereas the ADF content increased. Overall, cutting desho grass at 30-45 days optimized both the DM yield and nutritional value in the study areas.
该实验旨在确定德肖草的最佳刈割频率,以实现干物质产量和饲草质量的最大化。采用随机完全区组设计,设置了三个刈割间隔(30天、45天和60天),每个间隔重复四次。通过标准程序收集并分析了该草的农艺参数、干物质产量和化学成分。刈割频率对农艺参数和化学成分有显著影响,但对干物质产量没有影响。每隔60天观察到的植株最高且叶片最多,而30天时分蘖密度更大。每隔30天刈割德肖草可获得相对较高的干物质产量(8.64吨/公顷),这与其他处理结果相当。粗蛋白含量随间隔时间的增加而降低,而酸性洗涤纤维含量则增加。总体而言,在研究区域内,每隔30 - 45天刈割德肖草可优化干物质产量和营养价值。
