新疆卡拉苏口岸公路沿线区域野生饲用植物资源研究

Research on wild forage resources in the area along the highway of Kalasu port in Xinjiang

为了了解新疆卡拉苏口岸公路沿线区域野生饲用植物资源情况,结合相关资料,对新疆卡拉苏口岸公路沿线区域野生饲用植物资源进行调查,分析了该区域野生饲用植物的科属组成及其生活型和生态型特点,并对其适口性和营养价值进行了分析。结果表明:该区共有野生饲用植物21科76属134种,优势科有禾本科(25种,占总种数的18.66%)、菊科(21种,占总种数的15.67%)、十字花科(19种,占总种数的14.18%)、藜科(15种,占总种数的11.84%)、豆科(12种,占总种数的8.96%);生活型以草本植物为主,有124种(占该区野生饲用植物总种数的92.54%),木本植物有10种(占总种数的7.46%);依据生态型可分为旱生(21种)、中生(98种)和湿生(15种),分别占该区植物总种数的15.67%、73.13%和11.19%。依据适口性可将该区野生饲用植物划分为优、良、中、低4个等级,其中优等32种,良等31种,中等52种,低等19种。说明适口性较好的科有禾本科、豆科、菊科和莎草科等,综合分析发现利用价值较高的野生饲用植物有11种。

In order to understand the situation of wild forage plant resources along the highway of Kalasu port in Xinjiang,combined with pre⁃vious related information,the wild forage plant resources along the highway of Kalasu port in Xinjiang were investigated.The family and genus composition,life form and ecotype characteristics of wild forage plants in this area were analyzed,and their palatability and nutritional value were investigated.The results showed there were 21 families,76 genera and 134 species of wild forage in this area.The dominant families in⁃cluded Poaceae(25 species,accounting for 18.66%of the total species),Compositae(21 species,accounting for 15.67%of the total spe⁃cies),Cruciferae(19 species,accounting for 14.18%of the total species),Chenopodiaceae(15 species,accounting for 11.84%of the total species),and Leguminosae(12 species,accounting for 8.96%of the total species).Herbaceous plants were the main life forms with 124 spe⁃cies(accounting for 92.54%of the total species of wild forage in the area),and there were 10 species of woody plants(accounting for 7.46%of the total species).According to the ecotype,it could be divided into xerophyte(21 species),mesophyte(98 species)and hygrophyte(15 species),accounting for 15.67%,73.13%and 11.19%of the total plant species in the area,respectively.According to the palatability,the wild forage in this area could be divided into four grades:excellent,good,medium and low,of which 32 species were excellent,31 species were good,52 species were medium,and 19 species were low.The results indicated that families with good palatability included Poaceae,Le⁃guminosae,Compositae and Cyperaceae,etc.The comprehensive analysis found that there were 11 species of wild forage with high utilization value.
