Effects of Different Fertilization Levels on Yield and Quality of Tomato in Plastics Greenhouse

This experiment designed 6 treatments using Random Blocks,used jinpeng 1 tomato as the experiment material,effects of different fertilization levels on middle fertility land ranged,yield and quality of tomato were studied.The study was done to evaluate the relationship between fertilization level and the yield,quality in tomato,and to provide theoretical foundation for further research of increasing yield and improving quality.It had 2 treatments reached the target yield in all fertilization level,tomato yield and content of Soluble matter,Vitamin C,soluble sugar,Organic acid,nitrate were obviously superior compared with the control.And all were remark increased by increasing the amount of fertilization levels.But the excessive fertilization made various index of tomato was downtrend.Considering the factors of both quality and yield,about dry cattle manure 7 500 kg/667m2,carbamide 125 kg/667m2,calcium superphosphate 250 kg/667m2 and potassium sulphate 84 kg/667m2 as the optimal fertilizer rate during spring season tomato cultivation in plastic greenhouse with medium soil fertility according to experiment.
