A method for promoting the 
germination of ryegrass multiflora seeds and the growth of seedlings is to sow ryegrass multiflora seeds directly in a 
nutrient bowl equipped with a substrate, sow 1 to 3 seeds per 
nutrient bowl, and cover the upper layer with a substrate of 1.5 to 2.0 cm.  Press lightly, place the 
nutrient pot on the 
seedbed, add water to the 
seedbed to 1~1.2cm from the bottom of the nutrient pot, the water will completely infiltrate the substrate, before emergence, add water at any time so that the 
moisture content of the substrate is 35~40%, after 
germination, spray 
indium  Indoleacetic acid IAA solution.  The invention can make the 
germination rate of ryegrass multiflora seeds high, which can be as high as 93%, the germination index is high, which can be as high as 53, the 
vitality index is high, which can be as high as 448 or more, the growth of seedlings is good, the whole 
plant of seedlings can reach more than 11cm, and the seedlings can  The length is more than 8.4cm, the 
root length can be more than 2.5cm, the 
fresh weight of the whole 
plant can reach more than 4g, the 
fresh weight of the 
seedling can reach more than 1.48g, and the 
fresh weight of the root can reach more than 2.4g.  The cycle is short, the method of the invention is simple and reliable, and is worthy of market promotion and application.
