不同氮素施用模式对大棚番茄产量和品质的影响
The effects of different nitrogen application methods on yield and quality of greenhouse tomatoes
摘要
Abstract
[Objective]This study aimed to address the issues of soil degradation and reduced tomato yield and quality caused by improper nitrogen fertilizer application during the growth period of plastic greenhouses tomatoes.[Methods]In this experiment,the tomato variety'Ruifen 882'was used as the experimental material.The conventional farmer fertilization practices were used as the control(CK),and four different nitrogen application methods were tested:no nitrogen(T1),100%urea(T2),calcium ammonium nitrate replacing 75%of urea(T3),and chelated polypeptide calcium-magnesium fertilizer replacing 30%of urea(T4).The total nitrogen content in treatments T2,T3,and T4 was 95%of that in the control treatment.Indicators such as soil nitrate and ammonium nitrogen content,fruit yield,and quality were measured to compare the effects of different ni-trogen application methods.[Results]At 90 days after tomato planting,the T4 treatment reduced soil nitrate and ammonium ni-trogen content while increasing organic matter content in the 0～60 cm soil layer.The average membership function value of soil nutrients in the T4 treatment was 0.763,the highest among all treatments.T4 treatment also achieved the highest yield of 11.52 kg/m2,which was not significantly different from T3 treatment but significantly higher than other treatments,showing a 31.64%increase compared to CK.Additionally,the T4 treatment significantly improved the soluble protein,soluble sugar,and reduced vitamin C content in tomato fruits by 32.63%,12.00%,and 10.33%,respectively,compared to CK.[Conclu-sion]The application of chelated polypeptide calcium-magnesium fertilizer replacing 30%of urea effectively increased tomato yield and quality,making it a viable approach for improving soil fertility and nutrient supply in greenhouse cultivation.关键词
