The invention provides a method for recovering heavy metal contaminated soil through magnetotactic bacteria and chlorophytum comosum together. The magnetotactic bacteria and the heavy metal contaminated soil are mixed. The heavy metal contaminated soil mixed with the magnetotactic bacteria is irrigated. A magnetic field is set on the heavy metal contaminated soil, and the heavy metal contaminated soil containing the magnetotactic bacteria is collected, washed and filled back. The chlorophytum comosum is planted in the heavy metal contaminated soil primarily recovered through the magnetotactic bacteria and is removed overall after 90-100 days. The above steps are repeated until the content of heavy metal in the soil meets the safety standard. Compared with the prior art, the magnetotactic bacteria are easy to collect, and the chlorophytum comosum has high economic value besides recovering the soil. By means of the method, many kinds of heavy metal contaminated soil can be recovered at the same time, secondary pollution is avoided, and the method is suitable for treatment of large-area contaminated soil.

The invention discloses a method for promoting the germination and sowing of Chinese scholar tree seeds, belongs to the field of plant seed germination and seedling culture, and solves the problem that the germination rate of Chinese scholar tree seeds is low. The method comprises the following steps: mixing Chinese scholar tree seeds, Chinese scholar tree leaves, which are picked at the same time, and fine soil to obtain a Chinese scholar tree seed primary raw material, processing the primary raw material for 1 to 2 hours at a temperature of 50 to 60 DEG C, then steaming the primary raw material by diluted edible vinegar for 2 to 5 hours at a temperature of 55 to 65 DEG C, covering the primary raw material by a plastic film for 1 to 5 hours; removing the plastic film, screening out Chinese scholar tree seeds from the primary raw material, saving the Chinese scholar tree seeds for later use, before sowing, soaking the Chinese scholar tree seeds in a soaking liquid, which is prepared by blending purified water and white granulated sugar, for 3 to 8 hours at a temperature of 10 to 20 DEG C, and sowing the seeds. The method has the advantages of simple operation, low cost, few steps, and short time, and is capable of prominently improving the processing efficiency of Chinese scholar tree seeds. The germination of processed Chinese scholar tree seeds is quick, the quality of seed bud is good, and the survival rate is high and can reach 92 to 98%.

The invention discloses a wind-resistant and yield-increasing cultivation device for cassava, which comprises a bottom support plate, a bottom connecting ring, a field ridge covering base, a cultivation hole, a support rod, a cover, a cross bar, locking bolts, a sliding sleeve, a fixing pipe, and a through hole , pressing plate, long pole, barb, field ridge and cassava crops, the top of the field ridge covering base is provided with a loading hole, and the field ridge covering base is used to cover on the arranged field ridge, and the field ridge covering base is covered with a single cassava crop Planting area settings. The invention realizes the division of the cassava planting area through the structure based on the ridge covering base, so that the cassava crops in a plurality of small areas have good wind resistance, which is helpful for increasing the production of cassava; at the same time, the structure of the invention is stable , low cost, suitable for large-scale planting.

The invention discloses a stand column cultivation device and method. The cultivation device comprises a circular stand column and a plurality of layers of cultivation container supports which are arranged up and down along the stand column. The supports comprise a plurality of supporting arms, and the tail ends of the supporting arms are connected with the stand column. Steel rings for containing cultivation containers are arranged at the front ends and in the middle of the supporting arms, the steel rings extend out of the stand column through the supporting arms, the cultivation containers are arranged on the steel rings, accordingly, plants in the containers cannot be gathered on the surface of the stand column, growing spaces of the plants cannot be limited, meanwhile, a plurality of plants can be cultivated on each layer of support, large-area planting can be well achieved, and production cost is lowered.
