| 摘 要： | 为探明贵州高寒山区优质高产牧草黔饲1号小黑麦人工混播草地的适宜建植技术,采用随机区组试验研究饲用小黑麦与箭舌豌豆不同混播比例的生产效应。结果表明:混播处理的生产能力显著优于单播处理(P0.05),其中,黔饲1号小黑麦50%+兰箭3号箭舌豌豆50%混播处理的鲜草产量、草层高度、叶茎比及0~30cm土层的地下生物量均最高,分别为57 349.2kg/hm2、176.9cm、0.534 8和21 298.32kg/hm2。该混播模式具有较好的协同效应,可在威宁高原及类似地区推广应用。

Effects of Different Mixed Seeding Rates on Triticale and Vicia sativa Yield |
| |
| Abstract: | In order to explore an establishment technology of artificial cultivated grassland suitable for highland and cold area in Guizhou, forage triticale and V.sativa were used to study the production effect of mixed seeding.Random block design was employed to explore the effects of different mixed seeding rates on triticale and V.sativa yield.Results: Mixed seeding treatment, especially for mixed sowing with 50% triticale and 50% V.sativa treatment, was significantly higher than the clean culture treatments(P<0.05), with the highest fresh yield, layer height, leaf/stem, and underground biomass in 0~30 cm soil layer of 57 349.2 kg/hm2, 176.9 cm, 0.534 8 and 21 298.32 kg/hm2 respectively.Synergistic effect played an important role in grass biomass production.The mixed sowing model with 50% triticale and 50% V.sativa should be applied to plateau area in Weining and other similar areas. |
