Embodiment 1

[0024] In high-altitude areas without heavy metal pollution, set up 4 blocks, each 1 mu, marked as A, B, C, and D, and follow the steps below:

[0025] Preparation of soil solution A: Dissolve 50g of planting soil in 1000ml of distilled water at 25°C, and stir evenly.

[0026] Preparation of soil solution B: Dissolve 50 g of planting soil in 1000 ml of distilled water at 25° C., stir evenly, 2) add Bacillus subtilis, stir evenly, the content of Bacillus subtilis is (5×10 10 ) cfu / ml. Prepare the Bacillus subtilis soil solution.

[0027] Preparation of C soil solution: mix 50g of planting soil with rhizobia evenly, the content of rhizobia is 600-800 million / g, dissolve in 1000ml distilled water at 25°C, and stir evenly. Prepare the rhizobia soil solution.

[0028] Prepare D soil solution: mix 50g of planting soil with rhizobia evenly, the content of rhizobia is 600-800 million / g, dissolve in 1000ml distilled water at 25°C, stir evenly, 2) add Bacillus subtilis, stir evenly, ...

Embodiment 2

[0039] Set up 4 groups of land without heavy metal pollution in high-altitude areas, with 4 blocks in each group and 1 mu in each block, which are recorded as groups A, B, C, and D. Follow the steps below:

[0040] Sowing ground preparation: According to the remaining moisture after the crops before planting, only the surface of the seed bed is treated, the underground rhizomes of the previous crops are completely removed, the soil is finely broken, and the soil surface is leveled by raking.

[0041] Seed disinfection: use 2% NaCLO solution to sterilize alfalfa seeds, then rinse with distilled water 3 times, then use 75% ethanol to sterilize the seeds for 30 seconds, rinse with distilled water 3 times and dry them on sterilized gauze.

[0042] Seed treatment: Soak alfalfa seeds in 200-500mg / L potassium permanganate solution.

[0043] Preparation of group A soil solution: Dissolve 50g of planting soil in 1000ml of distilled water at 25°C, and stir evenly.

[0044] Preparation ...

Embodiment 3

[0055] Set up 3 groups of test fields in high-altitude areas without heavy metal pollution, each group of 6 test fields, each 1 mu. Follow these steps:

[0056] Sowing ground preparation: According to the remaining moisture after the crops before planting, only the surface of the seed bed is treated, the underground rhizomes of the previous crops are completely removed, the soil is finely broken, and the soil surface is leveled by raking.

[0057] 1-6 test plots were sprayed with cadmium salt solution with cadmium solubility of 0mg / l, 10mg / l, 50mg / l, 100mg / l, 200mg / l, 400mg / l respectively to simulate cadmium pollution test plots.

[0058] Test fields 7-12 were sprayed with lead salt solutions with lead concentrations of 0mg / l, 10mg / l, 50mg / l, 100mg / l, 200mg / l, and 400mg / l respectively to simulate lead pollution test fields.

[0059] Experimental fields 13-18 were sprayed with aluminum salt solutions with aluminum concentrations of 0mg / l, 10mg / l, 50mg / l, 100mg / l, 200mg / l, and ...

Abstract

The invention discloses a planting method for anti-heavy metal alfalfa in high altitude localities. The planting method comprises the following steps: treating a sowing ground, disinfecting seeds, soaking the disinfected alfalfa seeds in a potassium permanganate solution, then soaking the alfalfa seeds in a culture soil solution containing bacillus subtilis and nodule bacteria and sowing the alfalfa seeds with a base fertilizer; covering the seeds with thin soil and treading the soil after sowing; and spraying an oxalic acid solution near the sowing place in 3-5 days after sowing. The plantingmethod can improve the germinating ability of alfalfa in the heavy metal polluted soil in the high altitude localities, so that the ecological environment of the high altitude localities is protectedand development of animal husbandry is promoted.

Description

technical field [0001] The invention belongs to the field of agricultural planting, and relates to a method for planting alfalfa, in particular to a method for planting alfalfa which is resistant to heavy metals in altitude areas. Background technique [0002] my country has a vast territory, and the Qinghai-Tibet Plateau is known as the "roof of the world". High-altitude areas are rich in mineral resources and are important heavy metal minerals in my country. In recent years, with the economic development of high-altitude areas, mineral resources have been developed and utilized on a large scale. A large amount of heavy metals such as cadmium and lead remain in the soil, causing serious heavy metal pollution. Ecosystems at high altitudes have low resistance, and soils are easily damaged and difficult to restore. [0003] At present, soil heavy metal pollution in high-altitude areas in my country is serious. Although there are some studies on heavy metal super-accumulating p...
