The invention relates to the technical field of remediation of contaminated soil in the environment, and particularly relates to a method for removing lead from contaminated soil by virtue of taro leaf or achyranthes bidentata leaching. The method comprises the following steps: (1) preparing biomass leachate: washing a biomass material taro leaves with tap water, rinsing the taro leaves with distilled water, air-drying the taro leaves at a naturally-ventilated place, grinding the taro leaves by virtue of a crusher, sieving the taro leaves with a 2mm sieve, adding a proper amount of distilled water, performing oscillatory extraction on the mixed liquor for 12h, and performing filtration to obtain the leachate; (2) leaching the contaminated soil: adding the leachate obtained in step (1) into the lead-contaminated soil, regulating the pH value of the mixed solution to 4.4 to 5.0 by virtue of diluted hydrochloric acid and a sodium hydroxide solution, and performing oscillatory leaching. Achyranthes bidentata can be used instead of the biomass material taro leaves. The method is convenient and simple, an obvious leaching effect on the lead-contaminated soil is played, and secondary contamination to the environment is avoided.

The invention discloses a Rhizome corydalis and taro interplanting cultivation method comprising the following steps: simultaneously sowing Rhizome corydalis and taro from the first 10 days of October to the first 10days of November, wherein the taro is sowed, and then Rhizome corydalis is sowed; harvesting the rhizoma corydalis 4-6 days after the rhizoma corydalis plant is fully withered in the first 10 days of May, returning the rhizoma corydalis withered plants back to the soil, and earthing up the taro; drying the land after autumn begins; cutting petioles on the ground before harvesting, and harvesting the taro after wounds heal, wherein the best harvesting time is when the taro leaves turn yellow and fibres whither. The method simultaneously sow the Rhizome corydalis and taro, so taro sowing safe overwintering problems can be solved; two crops can be planted in one season, thus improving land utilization rate, and increasing yield per unit area; heavy fertilizer is applied in the Rhizome corydalis growth period, yet the fertilizer utilization rate is low, so mass fertilizer can be left after harvesting; the left fertilizer can be utilized by the interplanting taro, thus greatly improving fertilizer utilization rate.
