摘要
为提高设施栽培番茄产量和肥料利用率,以金鹏1号番茄为试材,采用随机区组设计,研究了相同N、P、K配比下增加施肥量对番茄果实N、P、K吸收和产量的影响。结果表明,所有施肥处理中有2个处理达到目标产量,产量结果与养分吸收结果基本一致,均随施肥水平的提高而提高,但肥水过剩的条件下,产量与养分吸收量又呈下降趋势。综合各因素,中等土壤肥力的塑料大棚番茄春季栽培中,推荐最佳施肥量大约每667 m2施风干牛粪7 500 kg,尿素125 kg,过磷酸钙250 kg,硫酸钾84 kg。每kg番茄果实(干质量)的氮、磷和钾含量分别为20.63 g/kg4、.3 g/kg和34 g/kg。
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 667m^2 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.
