Embodiment 1

[0031] A method for large-area planting of sedum with ore in the field, specifically comprising the following steps

[0032] (1) Land selection and land preparation: This test was carried out in a fallow land experimental plot in Zhuzhou County, Zhuzhou City in 2016. On November 18, a fertile, high-lying and easy-to-drain sandy soil field was selected, plowed 20cm deep, and the following year Before transplanting, carry out 4 times of rotary tillage, the depth of rotary tillage is 8 cm, and apply 100 kg of compound fertilizer (N, P 2 o 5 、K 2 O are all 15wt%), leveled and raked, poured sufficient water, and ridged the field on February 20, with a ridge width of 80 cm, a ridge height of 20 cm, and a ridge-to-ridge distance of 10 cm. Cover with mulch after spraying herbicides;

[0033] (2) Transplanting: On March 10, holes were punched on the film for transplanting. The diameter of the hole was 5 cm, the cutting depth was 4 cm, 4 rows per ridge, and the distance between rows ...

Embodiment 2

[0038] As a preferred embodiment of the present invention, a method for large-area planting of sedum with ore in the field, specifically includes the following steps

[0039] (1) Land selection and land preparation: This experiment was carried out in a fallow land experimental plot in Junchu Town, Liling City in 2017. On November 16, a fertile, high-lying and easy-to-drain sandy soil field was selected and plowed at a depth of 15 cm. , before transplanting in the following year, carry out 3 times of rotary tillage, the depth of rotary tillage is 5 cm, and apply 100 kg of compound fertilizer (N, P 2 o 5 、K 2 O are all 15%), leveling and raking, pouring sufficient water, and on February 25, the field was ridged, the ridge width was 60 cm, the ridge height was 15 cm, and the distance between ridges was 15 cm. Cover with mulch after spraying herbicides;

[0040](2) Transplanting: On March 5, punch holes on the film for transplanting. The diameter of the holes is 5 cm, the cutti...

Abstract

The invention relates to a method suitable for large-area planting of sedum plumbizincicola. The method comprises the following steps: rotary tillage is carried out before transplanting next year, field parcel ridging is carried out in late February, and field parcels are covered with mulch films after herbicide spraying operation; in early March, transplanting of the sedum plumbizincicola is carried out, and perforating and transplanting operation is carried out on the mulch films; in middle July, the sedum plumbizincicola is cut while stubbles that are 3 to 5 cm in length are left uncut, andthe stubbles can grow again; the cut sedum plumbizincicola is cut into 8~10 cm single-branched cuttings which are then immersed in an acetylsalicylic acid solution before subjected being cottage operation, a sunshade was set up above a planting area and harvest can be reaped in middle November. Via adoption of the planting method disclosed in the invention, survival rates of the sedum plumbizincicola can reach above 90%, a two season propagation coefficient can reach above 40 times, and weed removal rates are controlled to be more than 60%. The method is characterized by simple operation, small investment, good effects and the like; a problem of large area weed control in sedum plumbizincicola plantation can be solved, costs can be greatly lowered, and survival rates and the biomass of the sedum plumbizincicola can be remarkably increased.

Description

technical field [0001] The invention belongs to the technical field of soil heavy metal restoration plant planting, and relates to a method suitable for large-area planting of Sedum sedum accompanied by ore, in particular to a method for large-area planting of a zinc-cadmium super-enrichment plant in the field of Sedum sedum. Background technique [0002] Sedum with ore is a heavy metal tolerance and super-accumulator plant discovered in my country. It likes to be born in areas rich in Pb and Zn mines. It is a perennial succulent herb. The propagation of sedum sedum mainly includes seed propagation, tissue culture and stem / leaf cuttings, but the seeds of sedum sedum are extremely small, and seed propagation requires special climatic conditions, nutritional conditions and methods to break seed dormancy, so production It is difficult to use seeds for propagation; and tissue culture propagation is still in the stage of laboratory research due to immature technology, high cost o...
