PURPOSE: A fertilizer additive using portulaca oleracea l. plant is provided to enhance nutrient component of crops by increasing content of unsaturated fatty acid in crops. CONSTITUTION: A fertilizer additive includes unsaturated fatty acid extracted from portulaca oleracea l. plant. The portulaca oleracea l. plant is a mixture of one or more selected from purslane, Portulaca grandiflora HOOKER. and Portulacae Herba. The sampling method of the unsaturated fatty acid in the portulaca oleracea l. plant comprises the following carbonizing steps: heating the portulaca oleracea l. plant at 250-400 deg. Celsius for 30-200 minutes under anoxic condition; and processing the heated portulaca oleracea l. plant at 15-50 deg. Celsius for 45-300 minutes. |
