Salt Tolerance Evaluation Of Forage Oat And Its Planting And Harvesting Strategies

To explore forage salt resistant properties of oat and salinity soil influence on yield and quality forage oats,in baotou jiuyuan king of animal husbandry and so on six varieties forage for oatmeal carried out related research,on the basis of soil salinity measurement of testbed,the testbed is divided into mild,moderate,and moderate three salt gradient,and press the salinity gradient in six varieties of forage oat seed salt resistant test.Then,according to the results of salt-tolerance experiments on the seeds of the six varieties of forage oat,the six varieties were planted in the test plots with different salt gradients.The indexes of growth period,agronomic character,yield character and quality character of 6 varieties were systematically observed and compared.Relevant experimental results show that:(1)Different concentrations of salt stress had effects on seedling germination,plant plexus morphology,yield and quality,and the overall inhibition was observed.With the increase of salinity,the inhibition was stronger;among them,the medium salt concentration soil was more special.It has a certain promoting effect on seed yield,which is manifested by an increase in the ratio of grain to grass;(2)The salt resistance of the variety is from strong to weak:leader,shepherd,Baylor,Yan Wang,Baylor 2,Ai Wo;(3)Casting period:comprehensively consider the yield and quality,and the best feeding period is the milking period;(4)Modulation method:Among the 6 varieties,the leader and Baylor 2 are suitable for preparing hay,and the king,the swallow king,the Baylor and the Ai Wo are suitable for fresh feeding.
