摘要

固氮细菌和产生生长激素的根瘤菌的使用提供氮,增强植物对养分的吸收,并减少无机肥料的使用。由于经济、食品安全和可持续性因素,在水培系统中施用生物肥料作为减少合成养分的一种手段最近引起了人们的兴趣。本研究确定了水培系统中生物肥料用量对番茄产量的影响。采用随机区组设计,采用100%无机肥+ 0%生物肥(对照)7个处理,以及不同剂量无机肥与25%、50%、75%和100%生物肥的组合处理。结果表明,施用生物肥料增加了土壤内生细菌、固氮菌、固氮螺旋菌和增磷菌的数量,提高了土壤氮含量。与对照样品相比,不同的生物肥料组合没有改变番茄的磷和钾含量,但导致番茄等级更高。50%无机肥料和100%生物肥料的组合使果实重量比对照增加了36%。说明在番茄水培系统中施用生物肥料不仅有利于减少无机肥料用量,而且有利于提高果实品质。

The effect of beneficial microorganism as biofertilizer application in hydroponic-grown tomato
The use of N2-fixing bacteria and growth hormone-producing rhizobacteria delivers nitrogen, enhances nutrients absorption by plants, and reduces the usage of inorganic fertilizers. Implementing biofertilizer in the hydroponic system as a means to reduce application of synthetic nutrient is recently in interest due to economic, food safety, and sustainability factors. This study determines the effects of biofertilizer dose on tomato yields in the hydroponics system. A randomized block design was utilized that consisted of seven treatments, namely 100% inorganic fertilizer and 0% biofertilizer (control), and various doses of inorganic nutrient combined with 25%, 50%, 75%, and 100% biofertilizer. The result illustrated that the application of biofertilizer augmented the population of endophytic bacteria, Azotobacter sp., Azospirillum sp., phosphate solubilizing bacteria, and nitrogen content. The distinct combination of biofertilizer did not alter the phosphorus and potassium content compared to control samples however resulted in superior tomato grade. The 50% inorganic fertilizer and 100% biofertilizer combination amplified the weight of the fruit by 36% compared to the control. This finding indicates that the application of biofertilizers in the hydroponic system for tomato plants is not only beneficial in minimizing the dosage of inorganic fertilizers but also enhancing the fruit quality.
