| Abstract: |
| Xiyin No:2 barley cultivar belongs to that with six-edged and husk ears of half winterness.Plants grow densely with erect leaves and longawned and erect ears.Their crown layers are so good that light can well pass through.Plant height is 80-90 cm.And stems with 5 nodes and longnecked nodes but short at base are rough,strong,thickwalled,good elastic and lodgging-resistant.After all beading,the length of the main ears is similar to that of the tillering ears with uniform ear layers.The length of ear is 4.5-5 cm and spikelets are densely arranged with 50-60 barley corns per ear and seed weight being 30-34/1000.Barley corns are yellowish and uniform in size.This variety has such characteristics as high and uniform in size.This variety has such characteristics as high and stable yielding and good adaptibility with per mu yield can reaching 700-800 jin under good soil fertility and irrigation conditions.And per mu yield can reach over 1000 jin even under high soil fertility,water and good mangement conditions.Barley corn contains rough protein,11.22-12.45％,starch 59.1％ and amino acids 0.827％.Stalk and leaves are rich in nutrients and good for feeds.In order to get high and stable yield,the cultivar should be planted in the land with good fertility and better irrigation conditions,and it should also be rationally planted with right seed rate and in right time. |
