[目的]研究刈割次数对黑麦草产量和品质的影响.[方法]以大田栽培的黑麦草为试验材料,分别对其进行不同的刈割处理(①:刈割1次;②:刈割2次;③刈割3次;④:刈割4次),比较不同处理黑麦草的产量、再生能力及营养品质(粗蛋白、粗脂肪、粗灰分含量)的影响.[结果]处理③黑麦草的鲜草、干草、粗蛋白产量最高(分别为80.3、9.80、2.40 t/hm~2),分别为处理①、②、④的2.18、1.02、1.21倍,2.28、1.24、1.47倍及2.79、1.24、1.30倍;处理②、③黑麦草的再生能力较强;处理③黑麦草的营养品质最好,其粗蛋白、粗脂肪、粗灰分含量分别为24.469 7%、6.128 3%、14.910 3%.[结论]刈割3次黑麦草的产量最高、营养品质最好.

[Objective] The aim was to study the effects of cutting times on yield and quality of Lolium multiflorum. [Method] With L. multiflorum planted in field as the tested material, it was cut with different cutting times (①:cutting 1 time;②:cutting 2 times;③:cutting 3 times;④:cutting 4 times). The yield, regeneration ability and nutritional quality (contents of crude protein, crude fat and crude ash) of L. multiflorum in different treatments were compared. [Result] The yields of fresh grass, dry grass and crude protein of L. multiflorum in treatment ③ were the highest (being 80.3, 9.80, 2.40 t/hm~2 resp.), being 2.18, 1.02, 1.21 times,2.28, 1.24, 1.47 times and 2.79, 1.24, 1.30 times of those of L. multiflorum in treatments ①, ②, ④. The regeneration ability of L. multiflorum in treatments ② and ③ were stronger. The nutritional quality of L. multiflorum in treatment ③ was the best with contents of crude protein, crude fat and crude ash of 24.469 7%, 6.128 3% and 14.910 3% resp. [Conclusion] The yield of L. multiflorum which was cut 3 times was the highest with the best nutritional quality.
