摘要
高产优质的豆科饲草是高寒地区人工饲草发展的主选之一。为筛选适合西藏河谷农区种植的饲用豌豆新品种(系),采用隶属函数法对豌豆的农艺性状、产量和品质指标进行综合分析评价。结果表明,单株产量与单株荚数呈极显著正相关(r=0.809^(**)),与百粒重呈显著正相关(r=0.676^(*))。G0002305鲜草产量和干草产量均最高,分别为69434.7和15107.6kg/hm^(2),其次为拉萨黑豌豆和LB1202。不同豌豆材料之间粗蛋白、中性洗涤纤维和酸性洗涤纤维含量差异显著,且中性洗涤纤维与酸性洗涤纤维相关性极显著(r=0.976^(**))。饲草中矿物营养元素Ca、K、P含量差异显著(P<0.05)。24个主要相关指标隶属函数平均值排名为青豆>ATC196>PG2020-28>LB1202>拉萨黑豌豆>K-13>K-1541>CS6007>G0002305>PG2020-40>PG2014-87>草原7号。初步筛选出青豆、G0002305、LB1202和拉萨黑豌豆4个豌豆品种(系)作为优质饲用豌豆推广利用。
High-yield and high-quality legume forage is one of the main choices for the development of artificial forage in alpine regions.In order to breed new forage peas varieties(lines)suitable for planting in the valley agricultural areas of Tibet,the subordinate function method was used to comprehensively analyze and evaluate the agronomic traits,yield and quality indexes of peas.The results showed that the yield per plant was extremely significant positively correlated with the number of pods per plant(r=0.809^(**)),and significant positively correlated with 100-grain weight(r=0.676^(*)).The fresh yield and hay yield of G0002305 were the highest,69434.7 and 15107.6kg/ha,respectively,followed by Lhasa black pea and LB1202.The correlation among crude protein,neutral detergent fibre and acid detergent fibre in straw were extremely significant.There were significant differences in NDF and ADF among different pea varieties(r=0.976^(**)).The contents of mineral nutrient elements Ca,K and P were significantly different(P<0.05).The average value of membership function of 24 related indexes of agronomic traits,yield and quality from high to low were Green bean>ATC196>PG2020-28>LB1202>Lhasa black pea>K-13>K-1541>CS6007>G0002305>PG2020-40>PG2014-87>Grassland 7.Based on the above analysis,four pea varieties(lines)of Green bean,G0002305,LB1202 and Lhasa black pea can be used as high-quality forage peas.
