Investigation On Early Spring Plant Resources In Liaoning Province

Through the field investigation of early spring plant resources in Liaoning province,the composition,ecological type and utilization of plant resources of early spring flowering plants and early spring ephemeral plants in early spring plants in Liaoning province were further recognized and supplemented.More scientific development and utilization of recommendations and protective measures to provide a theoretical basis and scientific basis for the rational use of early spring plant resources.some important conclusions are as follows:There are a total of 125 species of early spring plants belonging to 22 families and 60 genera in Liaoning Province,all of which are distributed in angiosperms.Among them,64 species of early spring flowering plants belong to 18 families and 45 genera,and 30 families of small and medium-sized families and small families all account for the proportion of total species.46.88%,4 species of monotypic family,accounting for 6.25% of the total species.Among them,Asteraceae is a dominant species of 8 species and 6 genera;the dominant genus is 7 species of amaranth,accounting for 10.94% of the total species,and there are 33 genera belonging to a genus within the genus,indicating the composition of the genus of early spring flowering plants in Liaoning Province.Among the genus,the genus contains a variety of plants and is cumbersome.The life types of flowering plants in early spring were as follows: the growth type of buds was dominated by ground buds and aboveground buds,accounting for 51.56% of the total species;the growth type of plants was the most erect,accounting for 31.25% of the total species;The growth type has the most rhizome type,accounting for 39.06% of the total species.There are 61 species of early-season ephemeral plants belonging to 10 families and 19 genera,including 20 species of large families,accounting for 32.79% of the total species,26 species of medium-sized families,accounting for 42.62% of the total species,and 6 small and medium-sized families and small families.The species accounted for 9.84% of the total species,and there were 3 species of the monotypic family,accounting for 4.92% of the total species.Among them,the key to thedominant family of the early spring ephemeral plants in Liaoning Province is 20 species and 5 genera;the dominant genera are 27 species of Aster and Anemone,accounting for 44.26% of the total species,belonging to a genus of plants.Less,it can be seen that the composition of the genus of early spring ephemeral plants in Liaoning Province is less genus containing a plant.The life forms of early spring ephemeral plants are as follows: the growth type of shoots is up to 59.02% of the total number of shoots;the growth type of plants is the most upright,accounting for50.82% of the total species;the growth type of roots is rhizome type.Most,accounting for 49.18% of the total species.Liaoning Province has abundant plant resources in early spring.First of all,64 species of early spring flowering plants can be divided into five categories: 50 kinds of medicinal resources account for the highest proportion,accounting for 78.13% of the total species,followed by protection and transformation of the environment.Plant resources,once again,are edible plant resources,industrial plant resources and poisonous plant resources are the least;for 61 early spring ephemeral plants,they can be divided into six categories: 31 medicinal plants occupy the total number of short-lived plants in early spring in Liaoning Province.50.82% of the species,followed by edible plant resources,while plant resources,industrial plant resources and poisonous plant resources are relatively small for the protection and transformation of the environment.Only one kind of cherished plant is Oxalis obtriangulata L.subsp.japonica Hara.
