Abstract EN
The purpose of this study is to investigate the interactions between irrigation and fertilizer treatments on soil N O 3 - -N content and vertical distribution under drip fertigation in greenhouse tomatoes.
Randomized block design with three replications and the treatments consisting of three levels of irrigation and three levels of N fertilizer were used.
Three irrigation levels were W1 (100% E T 0 ), W2 (75% E T 0 ), and W3 (50% E T 0 ) and fertilizer levels were F1 (N240–P2O5120–K2O150 kg hm−2), F2 (N180–P2O590–K2O112.5 kg hm−2), and F3 (N120–P2O560–K2O75 kg hm−2).
The result demonstrates that dynamics of soil N O 3 - -N and its response to drip fertigation and levels of N moved toward the fore soil moist, and the average soil N O 3 - -N content with W3 treatment was 1.23 times higher than that of the W1 treatment in 0–60 cm at 43 days after transplanting.
The negative correlation between N use efficiency and levels of fertilizer N and the N recovery efficiency was increased with increases of N fertilizer application.
The fertilizer nitrogen rate greatly significantly influenced soil N O 3 - -N content.
Avoiding N leaching through controlled matching N fertilizer application and controlled irrigation to tomato N demand is the key to maintain crop yield and improve N use efficiency.
