Embodiment

[0032] An embodiment of the present invention provides a method for screening and planting germplasm resources of pasture grasses in grasslands. The screening method includes the screening of pasture grasses. The collection, preservation, evaluation, and selection of important plant germplasm resources such as genus are suitable for the establishment of artificial grasslands in arid and alpine regions, or the excellent leguminous and gramineous forage varieties that are competitive in supplementary grasslands, which are helpful for accelerating degraded grasslands. Vegetation restoration, improving the grass structure and nutrient ratio of natural grassland, improving the quality of grassland cattle and mutton production;

[0033] s1: First of all, focus on the collection, preservation, evaluation and utilization of important plant germplasm resources in grasslands; that is, the collection of important plant germplasm resources such as Leymus chinensis, Agropyrona, Brome, Elymu...

Abstract

The invention provides a screening and planting method for grassland pasture germplasm resources, and relates to the field of screening and planting methods for grassland forage germplasm resources. The screening method for the grassland pasture germplasm resources comprises screening of pasture, important plant germplasm resources such as leymus chinensis, wheatgrass, bromegrass, elymus dahuricus, medicago ruthenica and lespedeza in the grassland are collected, stored and evaluated, and excellent legumes which are suitable for artificial grassland establishment under arid and alpine region environmental conditions or have competitive power on reseeding grassland are screened. Pasture seeds and technical methods adapting to the arid and alpine regions in our province are mainly researched, and the regions also have the characteristics of the arid and cold regions in China, so that the method can form competitive advantages with similar researches in China; By implementing the method, technologies such as pasture variety cultivation, pasture high-quality and high-yield cultivation and the like in arid and alpine regions in the province are internationally connected, and particularly, the method has strong advantages in the aspects of parent selection and matching and dry farming cultivation technologies.

Description

technical field [0001] The invention relates to the technical field of forage germplasm resources screening, in particular to a screening and planting method for grassland forage germplasm resources. Background technique [0002] In terms of the collection and evaluation of forage germplasm resources, through the construction of the national science and technology resource platform "standardization, integration and sharing of forage plant germplasm resources" project, more than 30 superior units of national forage germplasm resources research have been combined to carry out the research of forage species in my country. It is the most systematic basic work in the field of germplasm resources, and has formulated more than 90 description specifications and data standards of important forage germplasm resources. It provides a wealth of research materials and information for the research of national 863, 973, national scientific and technological breakthroughs, basic scientific an...
