【目的】为昭苏燕麦与箭筈豌豆混播草地选择最适宜的混播组合及刈割时期提供科学依据。【方法】在昭苏地区进行燕麦与箭筈豌豆5种处理和2个刈割时期的田间试验,测定牧草产量、叶茎比及营养品质,并用灰色关联度法进行综合评价。【结果】蜡熟期燕麦与箭筈豌豆混播比例为46组合排名最高,综合生产性能最好。其次为乳熟末期燕麦与箭筈豌豆混播比例为64的处理,再次为蜡熟期混播比例为55的组合。【结论】燕麦与箭筈豌豆混播后,可显著提高牧草产量、牧草品质、资源利用效率和抗倒伏能力;基于灰色关联度法的综合生产性能评价,将燕麦与箭筈豌豆混播草地生产性能的内涵进一步扩展,建立高产优质的人工草地,并充分发挥其生产生态优势特性。
【Objective】 The objective of this study was to provide the scientific basis for selecting the most suitable mixed-sowing and mowing period for the ooze grass of Zhaosu oats and arrowhead peas. 【Method】 Field experiments were conducted in five treatments of oat and arrow 筈 peas and two cutting stages in Zhaosu area. The yield, leaf-stem ratio and nutritional quality of forage were determined and evaluated by gray relational method. 【Result】 The results showed that the mix proportion of oat and arrowhead pea in the waxy stage was the highest in the combination of 46, and the comprehensive production performance was the best. Followed by the milk end of the oats and arrowhead peas mixed sowing ratio of 6 4 treatment, again for the waxy mixed sowing ratio of 5 5 combination. 【Conclusion】 The results showed that the combination of oats and arrowhead peas could significantly improve pasture yield, forage quality, resource use efficiency and lodging resistance. According to the comprehensive production performance evaluation of gray correlation method, Connotation to further expand the establishment of high yield and high quality artificial grassland, and give full play to its ecological advantages of production characteristics.
