有机肥与无机肥配施对土壤肥力和番茄产量的影响

Effects of Organic-inorganic Fertilizers Combined Application on Soil Fertility and Tomato Yield

为明确不同比例有机肥与无机肥配施对番茄产量和土壤肥力的影响,以冬暖番茄为研究对象,田间试验设计4个处理,分别为常规施肥对照(CK)、施有机肥1 500 kg/hm^(2)+常规化肥施用量90%(T_(1))、施有机肥3 000 kg/hm^(2)+常规化肥施用量80%(T_(2))、施有机肥4 500 kg/hm^(2)+常规化肥施用量70%(T_(3)),3次重复,随机排列。结果表明,不同比例有机肥与无机肥配施不但能提高土壤有机质,增加土壤养分,减轻土壤酸化程度,还能不同程度增加番茄产量,以施有机肥1 500 kg/hm^(2)+常规化肥施用量90%、施有机肥3 000 kg/hm^(2)+常规化肥施用量80%处理增产较为显著,分别较常规施肥对照增产4.53%、9.05%,施有机肥4 500 kg/hm^(2)+常规化肥施用量70%处理增产不显著。综合分析认为,施有机肥1 500 kg/hm^(2)+常规化肥施用量90%、有机肥3 000 kg/hm^(2)+常规化肥施用量80%可以保证番茄增产、增效。

In order to study effects of different proportions of organic-inorganic fertilizers combined application on tomato yield and soil fertility,taking Dongnuan tomato as the research object,four treatments were designed as the follows:conventional fertilization(CK),application of organic fertilizer 1500 kg/hm^(2)+90%chemical fertilizer(T1),application of organic fertilizer 3000 kg/hm^(2)+80%chemical fertilizer(T2),application of organic fertilizer 4500 kg/hm^(2)+70%chemical fertilizer(T3),and each treatment was treated 3 times and randomly arranged.The results showed that,different proportion of organic-inorganic fertilizers combined application could not only improve soil organic matter,increase soil nutrients,reduce soil acidification,but also increase the tomato yield.Compared with the CK,the tomato yield in treatment of T1 and T2 increased significantly,the yield increased by 4.53%and 9.05%,respectively,the tomato yield in treatment of T3 didn't increase significantly.Comprehensive analysis showed that treatments of T_(1) and T_(2) could increase yield and efficiency of tomato.
