控失尿素施用量及不同配比对新疆加工番茄产量、品质、氮肥利用率的影响
Effects of Loss-control Urea Application and Different Ratio on Yield, Quality and Nitrogen Use Efficiency of Processing Tomato
摘要
Abstract
[Objective] A field experiment was conducted to study the effects of loss-control urea and common urea different application proportion on plant dry matters,nitrogen uptake and yield of processing tomato'Tunhe 9'.[Method] Eight treatments were designed,including CK(N 0 kg/hm2),common urea (N 240 kg/hm2),loss-control urea (N 240 kg/hm2),80% loss-control urea (N 192 kg/hm2),70% loss-control urea (N 168 kg/hm2),70% loss-control urea + 30% common urea (total N 240 kg/hm2),50% loss -control urea + 50% common urea (total of N 240 kg/hm2),30% loss-control urea + 70%common urea (total of N 240 kg/hm2) to research the effects of loss-control urea and common urea on accumulation rate for plant dry matters,nitrogen uptake and yield of processing tomato.[Result] The results showed that compared with conventional urea,the application of 70% loss-control urea + 30% common urea and 50% loss -control urea + 50% common urea could significantly increase the plant dry matters and nitrogen uptake,and fertilizer nitrogen use efficiency was increased by 12.28 and 9.05 percentage point,respectively;the biomass and yield between 80% loss-control urea and common urea treatments showed no significant difference,but the fertilizer nitrogen use efficiency increased by 11.94 percentage point.the application of 70% loss-control urea + 30% common urea and 50% loss-control urea + 50% common urea significantly increased the yield of processing tomato,respectively by 12.99% and 5.38%;Compared to the loss-control urea and common urea treatments,the application of loss-control urea could significantly increase the color difference,but the treatments had no effects on soluble solids,pH value and the total acidity.[Conclusion] The application rate of controlled urea and loss-control urea combined with common urea increased the utilization rate of nitrogen in processing tomato,but the application of 70% loss-control urea + 30% common urea treatment is the best.关键词
