摘要
为在新疆伊犁昭苏盆地筛选出综合生产性能较优的一年生豆禾混播草地,分别以毛苕子(Vicia villosa)+燕麦(Avena sativa)、毛苕子+小黑麦(Triticale)、箭筈豌豆(Vicia sativa)+燕麦和箭筈豌豆+小黑麦按豆禾牧草异行混播(豆科牧草:禾草为1:1、2:1、3:1和4:1)的方式建植栽培草地,将牧草产量、牧草营养产量、相对饲用价值和种间相容性作为指标体系,利用主成分分析法和模糊综合评价法分别对不同混播方式的生产性能进行综合评价。结果表明:1)毛苕子+燕麦在1:1混播时具有较高牧草产量、粗蛋白(CP)产量、粗脂肪(EE)产量和磷(P)产量;毛苕子+小黑麦和箭筈豌豆+燕麦均在3:1混播时具有较高的CP产量、EE产量,或较低的中性洗涤纤维(NDF)和酸性洗涤纤维(ADF)产量以及较高的P产量;而箭筈豌豆+小黑麦在1:1与4:1混播时生产性能相似。2)两种评价方法均显示箭筈豌豆+燕麦在3:1混播、箭筈豌豆+小黑麦在2:1混播、毛苕子+燕麦在1:1混播和毛苕子+小黑麦在4:1混播时具有较高的综合生产性能。因此,在评价指标相同的情况下,两种评价方法的评价结果具有相似性;箭筈豌豆+小黑麦2:1和毛苕子+燕麦1:1的豆禾异行混播方式具有较高的综合生产性能,适宜在昭苏盆地推广示范。
To screen for annual mixed soybean-grass grassland with higher comprehensive production performance in the Zhaosu Basin,Yili,Xinjiang,China,four mixed soybean-grass treatments of Vicia villosa+Avena sativa,V.villosa+triticale,V.sativa+A.sativa,and V.sativa+triticale(1꞉1,2꞉1,3꞉1 and 4꞉1,legume forage꞉grass)were designed to develop artificial grassland.Forage yield,forage nutrient yield,relative forage value,and interspecific compatibility were used as the indices to comprehensively evaluate the production performance.The production performance of the different treatments was comprehensively evaluated via principal component analysis and fuzzy evaluation.The results showed the following:1)The forage,crude protein,ether extract,and P hosphorus yields of V.villosa+A.sativa were higher at a 1꞉1 mixing ratio;the CP and EE yields of both V.villosa+triticale and V.sativa+A.sativa were higher at a 3꞉1 mixing ratio;otherwise Neutral detergent fiber and Acid detergent fiber yields were lower,and P yield was higher.The yield performance of V.sativa+triticale was similar at 1꞉1 and 4꞉1 mixing ratios.2)The results of both evaluation methods showed that the mixing ratios of 3꞉1 for V.sativa+A.sativa,2꞉1 for V.sativa+triticale,1꞉1 of V.villosa+A.sativa,and 4꞉1 of V.villosa+triticale produced higher overall production performance.Therefore,when the same evaluation indicators were used,the results of the two evaluation methods were similar.Higher comprehensive production performance can be achieved with a mixed-sowing method of V.sativa with triticale in a 2꞉1 ratio and V.villosa with A.sativa in a 1꞉1 ratio,which are suitable for promotion and demonstration in the Zhaosu Basin.
