Effects of Different Water and Fertilizers Treatment on Yield and Quality of Tomato Grown in Organic Sandy Substrate

A tomato cultivar(Jinpeng No.1)was used to study the organic cultivation patterns of different fertilizers and water management.The research studied the effects of different fertilizers and water managements on yield and quality of tomato.(95±5)%,(80±5)% and(65±5)%,were designed in the experiment.There were four fertilizer treatments in this study:Tl,supplied with organic substrates only and without inorganic fertilizer;T2,the fertilization amount:CO(NH2)2 1 084.665 kg/hm2,K2SO4 483.06 kg/hm2;T3,CO(NH2)2 1 812.825 kg/hm2,K2SO4 1 115.775 kg/hm2;T4,CO(NH2)2 2 540.835 kg/hm2,K2SO4 1 748.505 kg/hm2.The results showed that,under different fertilizer treatments,the soluble sugar,soluble protein and yield of tomato in treatment T3 was the highest in the same substrate relative water content.At the same time,Vc and soluble matter in treatment T4 was the highest.With the different water treatments under the same fertility conditions,the yield of tomato with the treatment H1 was higher than other water treatments while the quality appeared contrary trend.When tomato would be planted in organic substrate,from the view of yields and fruit quality,H2T3 could be taken as a quantitative index for water and fertilizer management of tomato.In addition,considered the higher fruit quality,H2T4 also can be an index for water and fertilizer management of tomato grown in organic substrate.
