摘要

本研究的目的是将有机废物和茶叶废物转化为有机土壤调节剂,并将有机废物的填埋和非法倾倒减少68%。将茶叶与有机废物按10%的增量比例混合,分组为T0-T100组,T0组为0%茶废物,100%有机废物,T100组为100%茶废物,0%有机废物。随后研究了该土壤调节剂对茄茄(番茄)植株生长的影响,并对酵母制造装置产生的废污泥进行了21周的增加。研究了堆肥的微生物检测及pH、温度、有机碳、碳氮比、水分、阳离子交换容量(CEC)、湿度等理化参数。目视颜色变化表明堆肥成熟,适合进一步施用。对堆肥前和堆肥后土壤质量进行了分析。土壤电导率为3.0 mho, pH 8.3,有机质0.84%,磷1.0 mg/kg,钾225 mg/kg,饱和度为40%。有机废弃物与有机质呈反比关系,T0组有机质含量最高。好氧T0组氮含量最高(9.07%),磷含量最高(0.7%),钾含量最高(2.3%)。好氧T100组有机碳含量最高(78.23%),CEC最高(109.09 meq/100g)。施用后番茄植株营养生长、开花结果均以T60处理最佳。综合我们的研究结果,可以得出结论,有机堆肥提高了土壤肥力高达70%,这对番茄植株的生长有积极影响。

Significant impact on the growth of Solanum lycopersicum in Microbially augmented organic waste
The objectives of this study were to convert organic and tea waste to organic soil cond conditioners and achieve a 68% reduction in landfilling and illegal dumping of organic waste. The tea was mixed at an incremental ratio of 10% with the organic waste, and the groups were designated as T0-T100 groups, indicating 0% of tea waste and 100% of organic waste in T0 group and 100% of tea waste, and 0% of organic waste in T100 group. The impact of this soil conditioner was later studied on the growth of the Solanum lycopersicum (tomato) plant for twenty-one weeks along with the augmentation of waste sludge from the yeast manufacturing unit. Microbial examination, and other physicochemical parameters like pH, temperature, organic carbon, C/N ratio, moisture, cation exchange capacity (CEC), and humidity of the compost were studied. A visual color change indicated the compost maturity for further application. The quality of the soil was analyzed in both pre-compost and post-compost applications. The electrical conductivity of the soil was 3.0 mho with 8.3 pH, 0.84 % organic matter, phosphorous 1.0 mg/kg, and potassium 225 mg/kg with a saturation level of 40%. There was an inverse relation between organic waste and organic matter with the highest percentage of organic matter in the T0 group. Maximum nitrogen content (9.07%), the highest levels of phosphorous (0.7%), and potassium (2.3%) were recorded in the aerobic T0 group. The highest amount of organic carbon (78.23%), maximum CEC (109.09 meq/100g) was found in the aerobic T100 group. The best vegetative post-application growth of tomato plants, flowering, and fruiting was observed in the T60 group. Taken together with our findings, it can be concluded that the organic compost boosted the soil fertility by up to 70% which positively affected the growth of tomato plants.
