牧草种子品质的好坏不仅直接决定着种子的种用价值,而且对播种后幼苗生长发育及牧草产量和质量也具有很大影响。随着大面积人工草地的建设,天然草地的补播改良以及荒山秃岭的绿化,都需要大量的优质牧草种子。鉴于目前我国牧草品种混杂,种子质量参差不齐的情况,我们对甘肃省几种主要栽培豆科牧草的种子品质进行了抽样检验。材料与方法一、材料来源供试牧草有豌豆、毛苕子、红豆草、苜蓿等10个种共20个品种。绝大多数牧草种子系由科研站和生产单位的种子田或大田生产的,因此可以代表一般情况。
The quality of pasture seeds not only directly determines the seed value, but also has great influence on seedling growth and forage yield and quality after sowing. With the construction of a large area of artificial grassland, the improvement of natural grass and the afforestation of barren hills, a large amount of high-quality forage seeds are needed. In view of the current situation of mixed forage species and uneven seed quality in our country, we conducted a sample test on the seed quality of several main legume forage species in Gansu Province. Materials and methods First, the source of materials for the test forage peas, hairy seeds, safflower, alfalfa and other 10 kinds of a total of 20 species. The vast majority of forage seeds are produced from seed fields or fields in research stations and production units and can thus represent the general situation.
