| Abstract: | Objective]The research aimed to raise fertilizer use efficiency,obtain high yield and high quality crops.Method] The effects of self-made chitosan coated slow release fertilizers on the growth of tomato,cucumber and corn was investigated.And the effects of fertilizers on agronomic characters,yield,fertilizer use efficiency and residual effect were compared.Result] The results of comparative cultivation of tomato and cucumber showed that the utilization efficiency of nitrogen was up to 58% with the application of chitosan coated slow release fertilizers.Conclusion] The chitosan coated slow release fertilizers had stronger effects to promote the stable growth of crops and realize the yield increase than that of available nitrogen fertilizer. |
