Experiment on Flotation Coefficient of Cnidium Monnieri Harvesting Isolate
摘要
Abstract
At present,Cnidium monnieri seeds are difficult to plant,difficult to mechanize,high harvest losses,high labor costs and low work efficiency.In view of the problems existing in the process of mechanized harvesting of Cnidium monnieri,the physical parameters of Cnidium monnieri isolates were determined,the suspension speeds and the floation coefficients of Cnidium monnieri seeds,leaves and stems were determined,derive the optimal wind tempo for wind-se-lected Cnidium monnieri seeds Isolates.The floation coefficients of the Cnidium monnieri seeds,leaves and stems were 0.065-0.069,0.052-0.055 and 0.033-0.036 respectively,which provided effective basic data for reducing the loss of mechanized harvesting of Cnidium monnieri seeds.The test results showed that the floation coefficient was positively proportional to the windage area of the material and inversely proportional to the mass of the material,which can be sorted by wind selection.Although there were differences in the windage area and mass of the seeds and leaves,the floating co-efficientt of seeds and leaves were similar,which made it difficult to sort them by wind power alone.Therefore,by choo-sing an appropriate harvest period and maintaining a certain harvest moisture content in Cnidium monnieri,the percentage of leaves and stalks in the isolates can be reduced,and the difference in the floation coefficients of the various isolates can also be improved.关键词
