摘要

The fertilizer formulations namely, CM - the composted chicken manure (a local formulation commonly used by farmers) were evaluated in combination with seven levels of biochar (0, 5, 10, 15, 20, 25 and 30%) and plant in the pots to enhance growth, yield and quality of the Ocimum basilicum in the acid soil (pH= 3,8-4,2) that located on the Sen Viet Farm, Binh Thanh District, Ho Chi Minh city, Viet Nam. The increase of 30% biochar some time makes the plant die and was not progressing of the Ocimum basilicum yield. At the concentration of twenty (20%) and twenty five percent (25%) biochar increased the growth and yield of the Ocimum basilicum plant, the yield increase 80% compared to the control and increased 120% compared to the local formulation. These combinations between biochar and CM at the suitable rates significantly improve the plant growth, the leaf weight (biomass) and the quality of leaf. Besides, the soil quality become better (pH=6,0-6,5). Hence the local compost formulation of in combination with 20% of biochar is recommended for better yield of Ocimum basilicum.

本文針對肥料配方（堆肥雞糞，農民常用的當地配方）與七種生物炭（0%，5%，10%，15%，20%，25%和30%）的組合進行評估，並研究針對位於越南胡志明市Binh Thanh區Sen Viet農場的酸性土壤（pH = 3,8-4,2），如何在盆栽技術中提高羅勒的產質量。當生物炭增加30％會使植物死亡，而控制在濃度為20%和25%的生物炭可以增加羅勒的產量。與對照相比，產量增加了80%，同時局部製劑相比增加了120%。藉由生物炭和堆肥雞糞之間組合，可以顯著改善了植物葉部的重量和品質。此外，土質可以改變得更好（pH = 6.0-6,5）。最後本文結論建議使用與20％生物炭組合的局部堆肥配方，可以獲得較佳的羅勒產量。
