不同豆禾混播组合在帕米尔高原牧区产草量和营养品质的比较
Comparison of grass yield and nutritional quality of different mixed sowing combinations of beans and grasses in pastoral areas of Pamirs Plateau
摘要
Abstract
The purpose of the experiment was to investigate the yield and nutritional quality of the mixed sowing combination of beans and grasses in Pamirs Plateau.The mixed sowing combination of Vicia sativa,Avena sativa,Triticale,and Secale was carried out.In the experiment,we set up mono-sowing 255 kg/hm2 of Bianfeng(B-D),255 kg/hm2 of Kaisu(K-D),255 kg/hm2 ofSujie(S-D),255 kg/hm2 of Jiedadongmu 70(J-D),and 150 kg/hm2 of Longjian 2(L-D)as control.Mixed 210 kg/hm2 of Bianfeng+120 kg/hm2 of Longjian 2(BL-H),210 kg/hm2 of Kaisu+120 kg/hm2 of Longjian 2(KL-H),210 kg/hm2 of Sujie+120 kg/hm2 of Longjian 2(SL-H),210 kg/hm2 of Jiedadongmu 70+120 kg/hm2 of Longjian 2(JL-H)as the treatment group,nine treatments were set up in the experiment,and the production performance and nutrition index were measured,and the grey relational grade was used for comprehensive evaluation.The results showed that the hay yield of JL-H was the highest(15.58 t/hm2),which was extremely higher than that of other mixed sowing combinations(P＜0.01).The crude protein content of SL-H was 12.73％,significantly higher than that of other mixed sowing combinations(P＜0.05).The content of NDF and ADF in mixed sowing treatment were lower than those in unicast grasses and higher than those in bean grass.The content of NDF and ADF in BL-H treatment was the smallest,which were 56.27％and 36.63％,respectively.The results showed that SL-H mixed sowing combination had the highest comprehensive evaluation value(0.218),and SL-H mixed sowing combination(210 kg/hm2 of Sujie+120 kg/hm2 of Longjian 2)was suitable for planting and application in pastoral areas of Pamirs Plateau if both yield and nutritional quality were taken into account.关键词
