| Abstract: | Based on original research on a seed coating formulation for Lespedeza davurica,in this experiment a fungicide(carbendazim,50%wettable powder),water retaining agent(super absorbent polymer,SAP),filling materials(corn stalk powder)and other coating materials were selected as ingredients for further testing and modification of the recipe.The tests were conducted with L.davurica cv."Jinnong No.1"and studied the effects of different formulations on seed germination and seedling growth of L.davurica.The results showed that carbendazim to seed ratio 1∶60 effectively solved the problems with seed decay and inactivation during seed germination.SAP at a range of concentrations was used as a water-retaining agent in the coating formulation,and 5%SAP was found to provide optimum efficacy.At this concentration of SAP,water was effectively held,and the seed vigor was the strongest with the highest germination index.In addition,5%SAP also resulted in a higher emergence rate and seedling growth rates in a greenhouse emergence test,indicating better seedling vigour.Adding corn stalk powder to the coating formulation was also beneficial.A range of powders of different fineness were tested.Among these,fine corn stalk powder(able to pass a 75μm sieve)resulted in a better germination status then the others tested and enhanced seedling biomass accumulation.The 1000-seed weight of the coated seeds was 2.3 times that of the naked seeds,and the coated seed diameter was close to 2 times that of the naked seeds.The tested seed coating formulation was therefore suitable for industrial production and mechanical seeding. |
