摘要
[目的]探讨不同施肥配方对番茄经济性状、产量和经济效益的影响,以提高番茄种植效益.[方法]试验设计5个施肥配方,1个常规处理,通过试验筛选最适宜番茄种植的施肥配方.[结果]在5个施肥配方中,以N∶P∶K =22∶ 20∶20(62％)的配比表现最佳,产量达40 122.30 kg/hm2,较当地常规处理增产6 750.75 kg/hm2,增产率达20.23％,产值为80 244.60元/hm2,较当地常规处理增加产值13 501.50元/hm2.[结论]综合番茄经济性状、经济效益、产量来看,以N∶P∶K =22∶20∶20(62％)施肥配方最优,该施肥配方设置合理,有利于番茄生长和产量提高.
Abstract
[Objective] To discuss the fertilization formula on the economic character,yield and economic benefit of tomato,and to enhance the planting benefit of tomato.[Method] Five fertilization formulas were designed in the test with one conventional treatment.The optimal fertilization formula was selected for tomato planting.[Result] Among the five fertilization formulas,formula N∶ P∶ K =22∶ 20∶ 20(62％)showed the best effects;the yield reached 40 122.30 kg/hm2,which enhanced by 6 750.75 kg/hm2 compared with local normal processing.The growth rate was 20.23％.Output value was 80 244.60 yuan/hm2,which increased by 13 501.50 yuan/hm2 compared with local normal processing.[Conclusion] Comparing with the economic character,economic benefit and yield of tomato,formula N∶ P∶ K =22∶ 20∶ 20(62％)is the optimal.This fertilization formula is reasonable and is helpful to the yield increase and growth of tomato.
