有机肥和化肥对盆栽番茄氮素利用以及损失的影响
Effects of organic and mineral fertilizers on nitrogen utilization and losses
摘要
Abstract
In order to elevate the tomato yield,nitrogen losses by ammonia volatilization and N2O emissions under the different types of N fertilizers,a tomato plot experiment was carried out on three equal amount of nitrogen fertilizer treatments,i.e.,manure (M),Urea (U) and combined application of manure and chemical fertilizer (MU) and two control treatments,CK (plant with no fertilizer) and CKN (no plant and no fertilizer).The results indicated that there was no significant difference of yield among M,MU and U treatments.Compared with U,the NH3 volatilization of M treatment reduced by 62％ and N2O emissions 53％.Compared with MU,the NH3 volatilization and N2O emissions of M treatment reduced by 57％ and by 69％,respectively.The amount of residual N fertilizer in the soil was in the order of M (64.9％) ＞ MU (36.7％) ＞ U (23.7％) and there was significant difference among them (P＜0.05).Considering of the nitrogen loss and crop yield,it was concluded that the organic fertilizer ensured high tomato yield and decreased nitrogen loss,which could be used as technical extension in tomato production.Due to the complexities of climate conditions,crop and fertilizer types,more comparative studies of environmental impact and crop yield of combined application of organic with chemical fertilizers need to be undertaken to further optimize the intensive vegetable production.关键词
