非饱和灌溉条件下番茄施肥减量技术研究
Reduction Fertilization for Tomato under Unsaturated Irrigation
摘要
Abstract
A field experiment of reductive fertilization on tomato under unsaturated irrigation condition was carried out to establish a technological system for irrigating and fertilizing scientifically.The results showed that the Nitrogen(N),Phosphorous(P2O5)and potassium(K2O)uptake rate and their absorptive intensities in different growth stages of tomatoes under drip irrigation were significantly higher than that in the treatment of conventional irrigation and fertilization.In addition,the yield and quality of tomato under drip irrigation were also significantly higher than that in the conventional irrigation and fertilization.Meanwhile,the amount of fertilizers used in drip irrigation could be decreased than that used in the traditional method.Especially,the N-fertilizer,P-fertilizer and K-fertilizer could be reduced 118 kg/hm2,15 kg/hm2 and 150 kg/hm2,respectively.Based on the results,it showed that the benefit of tomato production was increased significantly by fertigation which compared with the conventional irrigation and fertilization.It also suggested that the method of fertigation was a suitable irrigation and fertilization technique for tomato production in Guangxi.关键词
