Effect of Different Fertilizer Treatment on Nutrients Uptake of Tomato in Plastics Greenhouse

This study was to provide a theoretical foundation for further research of increasing yield and rational fertilization.This experiment designed 6 treatments using random blocks,used Jinpeng 1 tomato as the experiment material.The absorption N,P,K and yield on fruit of the increasing amount of N,P,K on same rate were studied.Results has 2 treatments reached the target yield in all fertilization level,the yield results basically identical to the results of nutrient uptake,all were remark increased by increasing the amount of fertilization levels.But the excessive fertilization make various index of tomato is downtrend.In conclusion about dry cattle manure 7 500 kg,carbamide 125 kg,calcium superphosphate 250 kg and potassium sulphate 84 kg per 667m2 as the optimal fertilizer rate during spring season tomato cultivation in plastic greenhouse with medium soil fertility according to experiment.The content of fruit(dry weight) N,P,K per kilogram were 20.63 g,4.3 g and 34 g.
