Abstract
[Objective]To select the drying agent which could accelerate the drying of Medicago sativa plants without reducing the seed quality and yield.[Method]The effects of different drying agents on the leaf-losing rate during maturing stage,water-losing rate of stems and leaves,seed quality and yield of Medicago sativa were studied.[Result]Different concentrations of paraquat all improved the relative water-losing rates in Medicago sativa stems and leaves,which were all above 50%,it also speeded up the drying process of Medicago sativa plants.Paraquat did not decrease the seed yield and thousand-seed weight,and had no effect on germination rate within the appropriate concentration range.K2CO3 increased leaf-losing rate significantly,water-losing rate of stem and leaf reached 16.58% by 5% K2CO3,and did not had negative effect on seed yield and seed quality,Na2SO4 increased seed yield,but its drying effect was worse than K2CO3,CaCl2 had the same effects as K2CO3,but its overall drying effect was worse than K2CO3.[Conclusion]The results provided theoretical support for the application of drying agents to the production of K2CO3.
