Preliminary Experimental Report on the Effects of Mineral Potassium Humate on the Germination and Growth of Corn Seeds
Through pot experiments,corn seeds were used as material,and mineral potassium humate solutions(100,300 and 500 mg/L)with different concentrations were prepared for seed soaking.Distilled water was used as the control to determine the seed germination rate,germination potential and germination index,as well as plant height,root length,root number,fresh weight and dry weight of seedlings,to study the effects of different concentrations of mineral potassium humate on the corn seed germination and seedling growth.The results showed that 100 and 300 mg/L potassium humate seed soaking was beneficial to the corn seed germination to varying degrees,effectively improved seed germination rate,germination potential and germination index,promoted the root growth,increased the fresh and dry weight of seedlings,and 300 mg/L showed the best performance.
