ABSTRACT

One of the main problems with soil chemistry of phosphorus (P) fertilizers is its limited availability by plants. Residual P remains on the soil surface and may cause environmental problems. The use of materials such as peat moss is not cost-effective in some countries due to its scarcity and high price. This study was performed to reduce the use of chemical fertilizers and limited expensive organic compounds in the cultivation beds to prevent environmental pollution and to investigate the effect of organic compounds from agricultural plant wastes and bio-fertilizers on characteristics of ivy geranium (Pelargonium peltatum). The experiment was carried out in a randomized complete block design (R.C.B.D) with 16 treatments and 4 repetitions. Cuttings were rooted and transferred to cultivation beds containing municipal solid waste compost, tea waste compost, leaf and wood compost, pond sediment and sand. Plant characteristics including morphological, biochemical, physiological and flowering parameters were evaluated at the end of the first flower shedding stage. Phosphate solubilizing microorganisms’ bio-fertilizer improved plant vegetative and generative growth. The best results were obtained in plants cultivated in a mixture of sand, tea compost, cocopeat and pond sediment. It could be concluded that phosphate solubilizing microorganisms as a bio-fertilizer together with a mixture of sand, tea compost, cocopeat and pond sediment as a new cultivation bed may be applied for suitable growth and development of ivy geranium.

摘要

磷 (P) 肥料土壤化学的主要问题之一是植物对其的可用性有限。残留的磷残留在土壤表面，可能导致环境问题。使用泥炭苔等材料在一些国家由于其稀缺性和高价格而并不划算。本研究旨在减少栽培床中化肥和有限昂贵有机化合物的使用以防止环境污染，并研究农业植物废弃物和生物肥料中的有机化合物对常春藤天竺葵（Pelargonium peltatum）特性的影响。）。实验采用随机完全区组设计（RCBD）进行，处理 16 次，重复 4 次。将插条生根并转移到含有城市固体废物堆肥、茶叶废物堆肥、树叶和木材堆肥、池塘沉积物和沙子的栽培床中。在第一次开花阶段结束时评估植物特征，包括形态、生化、生理和开花参数。磷酸盐增溶微生物的生物肥料改善了植物的营养和生殖生长。在沙子、茶堆肥、椰糠和池塘沉积物的混合物中种植的植物中获得了最好的结果。可以得出结论，磷酸盐溶解微生物作为生物肥料与沙子、茶堆肥、
