增施EM菌和生物纳米有机硒肥对番茄生长、产量及品质的影响

Addition of effective microorganisms and nano-bio selenium fertilizer affectsgrowth,yield,and quality of tomato

为探究增施EM菌和生物纳米有机硒肥对番茄种植过程的影响,以番茄多美瑞F1为试验材料,将EM菌和真希生物纳米有机硒肥进行根部淋施和叶面喷施,研究不同施用方式对番茄生长、产量和品质的影响。结果表明,施用EM菌和生物纳米有机硒肥对促进番茄的生长、提高产量和品质等方面有积极作用,不同施用方式的效果不同,其中T1处理根部淋施EM菌150倍液+真希500倍液3次+叶面喷施EM菌150倍液+真希300倍液2次的施用方式效果最佳,不但能促进番茄生长,提高产量(增产19.83%),增加果实中蛋白质、可溶性糖、维生素C和硒含量,显著降低果实中重金属镉含量,还能改善风味,提高经济效益。

In this paper,in order to explore the effect of increasing effective microorganisms and nano-bio selenium fertil-izer on the planting process of tomato,the tomato duomeirui F1 was used as the test material through root spraying and leaf spraying with effective microorganisms and zhenxi nano-bio selenium fertilizer,we studied the effects of different application methods on growth,yield,and quality of tomato.The results showed that it had a positive effect on promoting the growth,yield and quality of tomato when applying effective microorganisms and nano-bio selenium,and it had differ-ent effects on different application methods.Among these application methods,3 times of root spraying with 150 times of effective microorganisms+500 times of zhenxi and 2 times of leaf spraying with 150 times of effective microorganisms+300 times of zhenxi was the best application method.It could not only promote the growth of tomato,increase its yield(by 19.83%),increase the content of protein,soluble sugar,vitamin C and selenium in fruits,significantly reduce the content of heavy metals(Cd)in fruits,but also improve flavor and economic benefits.
