The Research Of The Productive Technique And Rule Of Alfalfa

The study on alfalfa planting and harvesting in large scale is carried in modern agricultural demonstration areas of JinHe in accordance with situation of alfalfa use, in order to Establish and improve a set of Coordinated Technology of alfalfa production and industrialized Exploitation. The result of alfalfa planting in large scale indicated that alfalfa germination,growth and yield is influenced by soil improvement,seed treatment,planting technology. It can improve the character of soil and alfalfa germination that soil is treated by KangDiBao at 15kg/hm2.The effect of weed controlling is better when soil was treated by Trifluralin as 2100ml/hm2. Alfalfa high of Rhizobia inoculatio is higher than alfalfa high of no Rhizobia inoculatio as 24%. negative relative relationship is found alfalfa germination to seeding depth, the best seeding depth is 2cm.The technology of planting alfalfa in large scale is established in hohhot by systematic study on every link of planting. And Technical specification and regulation of alfalfa mechanization Planting technology is established.The result of alfalfa mechanization harvesting indicated that yield and quality of alfalfa is effected by different harvesting time,cutting way,raking time,bailing time. The results are indicated as follows: when alfalfa is raking at any time with moisture content 40% and alfalfa is cutting at any time with moisture content 22%, the character and leaf preserving rate of alfalfa is high.And Technical specification and regulation of alfalfa mechanization Planting technology is established by study on every liking of harvesting.
